Today, photovoltaic installations are the order of the day, having become a real and affordable way to promote sustainability and energy savings in the home. With a truly rapid payback period, taking advantage of incentive packages in the form of subsidies or grants, we can achieve energy self-consumption in our homes in a simple and cost-effective way. The main challenge facing solar installations lies in the lack of production during the night, which interrupts the self-consumption cycle if a storage system is not available. This situation prevails in all renewable energy sources, which, because they are cyclical (solar energy) or inconsistent (wind energy), do not fully achieve their efficiency and effectiveness, preventing the coordination of a stable, sustainable, and constant system. To close the loop, we manage their entire production capacity through instantaneous consumption and the accumulation of surplus energy (not consumed immediately) by storing it, which is consumed during periods of productive slack within the system itself, through batteries.

Why it is essential to have a hybrid and battery inverter

Installing batteries to store the energy generated in the morning is both advisable and necessary. Not only to save money, but also for family and personal safety, ensuring that electricity remains available even if there are interruptions (micro-outages) in the power supply, and even if we experience a major blackout, such as the one that occurred in Spain on April 28, 2025.

When we install solar panels, the most common “due to price” is that the installation company suggests installing the typical simple photovoltaic inverter (Huawei is the best-selling brand in Spain), without considering (until now) the option of installing batteries in the medium term to, as we said before, close the circle of renewable energies completely and profitably. To operate a photovoltaic system, a simple inverter is enough for the solar panels to produce their full energy capacity; however, to take the next and obligatory step of accumulating that excess energy in batteries, it is essential to install a so-called “Hybrid” inverter , which makes it possible to manage and consume the energy from the panels in addition to accumulating the excess energy in the batteries, and consume it later.

It’s very common for installers to provide their clients with one or two solutions at most. It’s always advisable to explain the pros and cons of each system, as they will typically recommend a simple inverter or a hybrid one. It’s very important for installers to understand the client’s reasons for wanting to install solar panels at home, their consumption habits, and their expected future consumption, in order to properly size the entire system (both the inverter and the kWp of installed panels). It’s quite common for people to opt for the cheapest system, but we must weigh the pros and cons of each decision. Another important aspect is that each inverter brand usually offers clients battery models that are usually from its own brand, and few inverter brands are compatible with most battery brands on the market (and vice versa), which further complicates the choice of system due to incompatibility issues.

To give a clear example, in Spain and other parts of Europe, the best-selling brand is Huawei. Huawei’s equipment is very limited in terms of compatibility with external batteries (it does not offer third-party compatibility). With backup systems other than its own, we can basically only use its own LUNA2000 batteries plus the corresponding BMS. This means that the entire system (inverter if it needs to be replaced with a hybrid, batteries, BMS, backup, and stand) takes up a lot of physical space, requires an additional installation system, and requires the knowledge of an approved installer. In short, this solution is tremendously expensive compared to other options on the market, which actually improve both product quality, price, and installation time.

The “All in One” battery system from NEWBATT’s UHome Series , comes to solve all the problems we have mentioned in previous points, and to facilitate the customer’s decision when choosing which system they need to implement in their home, and not have power outages or lack of energy. The solution of this brand is much smaller in size , has a really good design with hardly any wiring, a more economical price , and a backup capacity so fast that we will not notice a cut in the power supply in our home, that is, we have a giant UPS throughout our home. In addition, this solution has a fire protection system that provides NEWBATT and our home with great security.

Main features

The NEWBATT UHome Series consists of a hybrid solar inverter with battery support and backup output, as well as one or more batteries with a capacity of 5kWh each. We must clearly differentiate between the inverter’s power in kW, which will be the maximum power it can provide through the grid and backup power in your home, and the battery capacity, which is measured in kWh and can be purchased in 5kWh increments since they are modular.

Investor

This inverter has the following technical characteristics. Depending on your power needs, you will have to choose one model or another; the only difference is the power it is capable of providing.

• Input power via solar or grid, and output via backup : between 3kW and 8kW maximum.
• Photovoltaic current input : we have 2 strings of up to 14A of current intensity.
• Maximum efficiency : 97.6% system efficiency.
• IP65 protection against dust and water, allowing indoor and outdoor installation.
• Fully modular design and Plug&Play : no wiring required between inverter, BMS and batteries.

In the following screenshot you can see the detailed technical characteristics of all the available inverters:

As you can see, it has some really interesting features. You’ve already seen how compact it is, measuring just 67.5 cm wide x 41.5 cm high x 20 cm deep. The inverter weighs 34 kg.

Batteries

The batteries are completely modular, making it perfect for installing a 5kWh capacity first, then expanding the energy storage later if necessary. In addition, expanding capacity is as simple as adding another module, without the need for any wiring.

• Battery capacity : 5kWh per module.
• Completely modular vertical design .
• It allows the battery to be expanded up to 20kWh on the same “tower” along with the inverter. If we need more, we’ll have to place the rest of the module next to it and wire it up.
• LiFePO4 battery : safer, longer-lasting and more reliable than other batteries with similar characteristics.

In the following screenshot you can see the detailed technical characteristics of all the available inverters:

As you can see, they have a very compact design, measuring just 67.5 cm wide x 36.5 cm high x 20 cm deep. This 5 kWh battery weighs 53.6 kg.

On the official NEWBATT website, you can find all the detailed technical specifications for both the inverter and the batteries. All specifications have been taken directly from the official source.

Management software

As for management software, the inverter has a touchscreen where we can view the system status , make advanced adjustments, and also see any potential alerts. This feature is really useful for seeing everything that’s happening without a Wi-Fi or internet connection, as we can view everything completely locally. If this battery system is installed in a location isolated from the internet, it will continue to operate without problems, although you won’t be able to view the status using the various tools available.

Of course, we have a web-based platform where we can view the status and make certain adjustments, as well as the app available on the official Google Play and App Stores . Additionally, something we value very positively is that it integrates with any home automation system thanks to the MQTT protocol . In our case, we have all the home automation with Home Assistant. We can configure the NEWBATT UHome with the MQTT server with the corresponding user credentials, and it will send us all the detailed information.

How much money is saved with this energy system?

When we have a solar photovoltaic installation, we typically use the self-consumption option with surplus compensation. This way, we buy energy from our supplier at a price of around €0.15/kWh and sell it to them at a price of around €0.06/kWh. Depending on the agreement we reach with the supplier, we can lower the import price and raise the export price. Nowadays, the supplier will buy energy from us at a very low price, making it worthwhile to install batteries to recoup the investment much more quickly.

To give you an idea of the savings this represents when it comes to energy imports, in May 2024, when we didn’t have these batteries, we imported (from May 1 to May 19) a total of 135 kWh.

However, with the battery, we imported only 34.8kWh, almost four times less. We saved about 100kWh on imports, with roughly similar household consumption.

If we have a 24-hour flat rate at a price of €0.15/kWh, we have gone from paying about €20 to paying just €5 during this period, so the savings are 75% in our case.

The key lies in how much we are paid for the surpluses. Retailers are paying increasingly less money per kWh, making it very difficult to recoup the investment in panels. Each individual case is different; you’ll have to do the math to determine whether installing panels at home, and also adding batteries, is worth it. Remember that batteries will not only allow you to save money, but they will also allow you to have electricity, even if there is a major blackout like the one that occurred in Spain on April 28, 2025.

In our personal case and the tests we’ve conducted, this system typically uses 1kWh of daily consumption (import) from the external electricity grid , so we’ll consume approximately 25kWh-30kWh monthly. If you sell surplus electricity to the retailer, you’ll likely pay €0 of the variable price, although you’ll always have to pay the fixed price (power) if you don’t have the so-called “virtual battery,” which will also be discounted from the fixed portion of your bill.

Reasons to buy NEWBATT Uhome instead of other alternatives

We currently have high-quality products on the market. Depending on the features you need and your budget, you can choose one solution or another. In our opinion, we believe this solution is one of the best right now for the following reasons:

• Compatible with all existing photovoltaic installations : it can be installed next to any existing inverter, but the panels can also be connected directly to the inverter.
• Advanced fire protection system : we have battery-powered sensors, with automatic extinguishing by cooling.
• Ultra-fast backup : allows you to create a backup in less than 20ms, perfect for ensuring you don’t detect any outages on critical equipment like computers or servers. The response is instantaneous.
• All-in-One : We have an inverter with the BMS, batteries, and power management all in one, with a compact and truly attractive design. It’s IP65 certified, so it can be installed indoors or outdoors.
• Up to 40kWh of storage : the installation is modular and stackable, perfect for reducing space usage, simplifying assembly and reducing installation time.
• Multiple power sources : Supports photovoltaic, wind, external generator, and grid power.
• Advanced software-level features : allows for no grid discharge, island mode, and others.
• Completely silent : it has passive dissipation, without fans, so it is totally silent.
• Long and reliable lifespan : allows more than 6,000 charge and discharge cycles, and is maintenance-free.

Now that we’ve seen the main features of this energy system, let’s move on to an external analysis so you can see all the components in detail.

External analysis

The NEWBATT UHome Series energy system  is completely modular , with a carefully designed design that allows it to be installed in any home and looks really good, with hardly any cables visible. The first thing we need to put on the floor of this solution is its base. This metal base has connectors where we will later place a 5kWh battery module. Then, if we want to install more batteries, we will have to stack them one on top of the other , also including the inverter, which will be at the top of the head.

The battery is perfectly protected by corks and plastic. To move these 5kWh batteries, it’s recommended that two people do so because they weigh quite a bit, about 55kg. You can see all the connectors on the sides, as well as on the bottom and top.

This battery must be installed directly above the metal base we saw earlier, making the correct connection. On the right side, we can see a small handle to make it easier to install it on the base. On the left side, we also have this same handle, some connectors, and a power button for the battery itself. If we want to turn off a battery, we can do so simply by pressing the “Power” button. Once installed, on the left side, you can see a connector, on top of which we can install another battery, or directly the NEWBATT UHome inverter.

As for the NEWBATT UHome Series inverter, it’s a truly complete unit. Inside the box, we can see the following contents:

• MC4 connectors for solar.
• Clamp meter that we must put on the general phase of the house, it has an RJ-45 connector to connect directly to the inverter.
• Connectors for grid (electrical network) and load (backup system) that we will have to use later.
• USB Wi-Fi adapter that we will connect to the inverter, and that must be connected to our Wi-Fi network to manage and monitor the system.
• Hardware and accessories for correct assembly.

On the left side of the inverter is where we can see the photovoltaic input. We have two strings, each with a current of up to 14A. We also have the photovoltaic shutoff switch, as well as the main shutoff switch for the inverter, and therefore for the power system. Finally, we find the battery connectors.

On the right side is where we have the grid (connection to the electrical network), and also the load (backup for critical loads in our home), in addition, we will also have the USB connector for the Wi-Fi network, as well as the CT (clamp meter).

In the following photo, you can see the NEWBATT UHome Series with a 5kWh battery and the 5kW inverter directly above it. However, as mentioned above, this system is completely modular; simply add another battery between the current battery and the inverter, and you’ll automatically have 10kWh of storage.

In the following gallery, you can see the final installation with a total of 10kWh of battery (two modules), as well as the inverter on top. Along with the batteries and inverter, we have different covers to hide absolutely everything, except for the “Power” buttons on the batteries and the top section, which houses the photovoltaic input and the main on/off switch.

On the right side is where we have the USB adapter input. It’s recommended to use a USB extension cable so we can position the antenna in a better position for better signal reception and to avoid coverage issues. We also have the CT input, which is the current clamp. This is done through a familiar Ethernet network cable, as it only uses two wires internally to receive data.

Just below, we can see the GRID socket, which will be connected to our home’s electrical grid, and the LOAD socket is the critical or backup load socket. In our case, the entire home is connected to the LOAD socket except for the electric vehicle charger, which also has a socket, so we can continue to have normal power at home. Sometimes, it may be a good decision to remove large loads such as the oven, AC, and others from the backup socket, but that depends on your needs and the inverter’s power.

To install a backup system in the home, certain modifications must be made to the electrical panel . Basically, we must connect all the loads directly to the LOAD in the garage, and for that reason, we will need to run cables to the main panel, and we also need to run cables from the Automatic Main Circuit Breaker (AMC) to the inverter’s GRID. This way, in the event of a power outage, the inverter will automatically activate an energy island, disconnecting from the external electrical grid and continuing to provide power to the house through solar production and the batteries. In the following gallery, you can see the differences in the upper left part of the electrical panel, removing the EV charger’s automatic circuit breaker (to place it inside the charger itself), thus making room for the necessary wiring.

Of course, it’s also necessary to run all the wiring through the garage conduits. If they don’t fit, additional conduits would be necessary to carry all the electrical wiring. A very important aspect is that in the auxiliary electrical panel, we’ll have an automatic switch for the GRID, another automatic switch for the LOAD or backup, and we also have a selector switch . In case we want to bypass the inverter due to some kind of error or failure , we can always lower the selector switch so that the power will not pass through the NEWBATT UHome Series.

As you can see, the NEWBATT UHome Series has a truly beautiful design, perfect for any home. What impressed us most was its size, which is truly compact. The system is only 22 cm deep, perfect for placing in a garage so it doesn’t get in the way when parking the car or other vehicles, as is the case with us.

Now that you know what this NEWBATT UHome is like, we’re going to show you all the configuration and customization options available in the different menus, both on the touch screen, via the web, and also with the official app.

This is how we tested the NEWBATT UHome Series

For this comprehensive analysis, we used the NEWBATT UHome Series system (5kW inverter model with two 5kWh battery modules, totaling 10kWh capacity) installed in a standard single-family home since March 2025. For over 3 months, we evaluated the following key aspects:

• Energy and economic savings: In May 2024, we imported a total of 218 kWh into our home, usually at night when there is no sunlight to generate energy, and we exported 465 kWh. In May 2025, with this system installed, we imported a total of 45 kWh and exported 206 kWh. Depending on your home’s electricity rate, and if it has a virtual battery so that it also deducts from the fixed energy bill, you could easily have a €0 bill. But the most important thing is to be sure that we will never run out of electricity.
• Backup system performance: The configuration we’ve implemented in my home is that everything in the house, except for the electric vehicle charger, goes through critical loads, also known as “LOAD.” We’ve run numerous switching tests in the event of power outages from the outside, lowering the IGA (Automatic Main Switch), and in every case, the system has provided power immediately, without any interruption in power, neither to our PCs, which are the most sensitive, nor to any household appliances.
• Battery life: This depends on how much power you require from the system and for how long. In our case, we average about 0.4kWh, so it lasts all night until the next day without any problems. This also depends on the number of hours of sunlight we have, and when the inverter starts and stops producing energy.
• Ease of use and interfaces : Using the inverter’s touchscreen is very easy to understand, although we’ll need to understand a minimum of how the system works. We can also monitor the system in detail through the UCANESS web platform and mobile app, which also allows us to make certain adjustments.
• Integration with home automation: This system allows us to send data to our home automation system with Home Assistant via MQTT, perfect for storing a complete history of all values, such as voltage (V) and power (W) of the battery, PV inverter, grid, and backup, perfect for keeping everything under control.

During the testing of this system, we suffered the blackout of April 28, 2025, although in our home we didn’t even notice that the power had gone out throughout Spain, because everything continued to operate electrically normally. However, we have a Huawei inverter to produce energy; in this case, the Huawei inverter was disconnected from the grid and produced absolutely nothing. To recharge the batteries, we had to connect the solar panels directly to the NEWBATT inverter, and thus we would have electricity coming from the panels and also from the battery itself. This is something you should keep in mind: the system is compatible with other inverters, but in the event of a power outage, that other inverter will not be able to produce energy to recharge the batteries; instead, we will have to connect the panels directly to the NEWBATT inverter.

Inverter Touchscreen Options

The NEWBATT inverter has a truly comprehensive touchscreen. Not only can we see the overall status of the energy flowing through the home, but we can also configure advanced operating settings. In the main menu, we can see the energy supplied by the photovoltaic panels (if connected), the energy coming from the grid (positive value) or exported (negative value). We can also see whether the battery is charging (positive value) or discharging (negative value). In addition, we can view our home’s consumption, all in real time.

If we click on the icon to the right of the house, we can access the overall status with voltage, current, power, and other advanced information, including the photovoltaic energy, the electrical grid, the house, the battery, and also the temperatures and voltages of the system itself. Thanks to this, we can see the overall status of the system at all times.

In the “Notices” section, it will alert us if there is any fault or warning. We must keep in mind that if you configure the battery to stop discharging at 20%, as soon as it reaches that 20% it will send us a warning. It is not really an error because it is something we have configured ourselves, but we will see the “Batt. Low Capacity” message that you can see in the images. If you configure the battery to stop discharging at 50%, it will also warn us with the same message. Then, once the battery rises above that percentage and a certain amount of time passes, it will automatically disappear. This warning does not appear either on the web or in the app.

We can also view statistics on energy consumption in kWh from both the grid and the battery, as well as solar energy production if we have solar panels connected.

As for configuration and customization options, the first thing we can configure is the screen brightness and the time it takes to go to sleep. The configuration options in the “Inverter” tab are as follows:

• System Settings : Here we can configure the operating mode and photovoltaic input, as well as other advanced settings. Don’t touch anything unless you know what you’re doing.
• Batt Settings : This is the most important part. The “ On Grid DOD ” value tells you how deep the battery will discharge if there is outdoor power, and the “ Off Grid DOD ” value tells you how deep the battery will discharge if there is no outdoor power (a power outage, for example). Setting the “On Grid DOD” to 80% means the battery will stop discharging when it reaches 20%. Setting the “Off Grid DOD” to 90% means the battery will stop discharging when it reaches 10% (in case of a power outage, we force it to reach 10% to have more light hours at home). We shouldn’t touch the rest of the parameters.
• Run Settings : Here we have the settings related to the voltage and Hz of the electrical grid, as well as the standard used on the grid. We shouldn’t touch these values.
• Grid Settings : allows you to activate and deactivate certain configuration options, in principle, we should not touch the default configuration for everything to work correctly.

As you’ve seen, we have many configuration options that we can adjust via the touchscreen. However, through the installation company, you’ll have even more advanced configuration options to tailor the device’s behavior to your needs.

NEWBATT UHome web options

The installation company will create a user account for you so you can use the web-based graphical user interface and the app. You’ll need to log in to the official UCANESS website , enter your email address and password, and then access the web-based monitoring panel.

On this monitoring panel, you can find all the information related to solar production, if you have connected the solar panels to the NEWBATT UHome. You can also view consumption graphs and statistics, the general and current status of the home in terms of production, power demand from the electrical grid, battery status, and the status of the home. Of course, you can see information on voltage (V) and current (A) throughout, as well as the grid frequency (typically 50Hz).

In the central section, we can see other installation details such as the firmware version, private IP address, the Wi-Fi network to which we have connected the UHome, as well as the serial number and other information. In this web-based menu, we can only change the inverter’s general operating mode (load matching mode, off-peak tariff arbitration, and backup power mode), as well as reset the Wi-Fi module in case of problems.

In the ” Settings ” section , we can change the inverter’s operating mode. Normally, for self-consumption, you should choose the first option, so that the battery is recharged with solar panels, whether those from the UHome itself or another inverter you have connected to the grid, as it is perfectly compatible if they are connected to the ” Grid ” network.

As you can see, the web-based user interface allows you to view many detailed statistics, including the current status of the energy system. Using the smartphone app, you can configure further settings, as we’ll show you now.

NEWBATT smartphone app

The app for installing, managing, administering, and monitoring the UHome is quite comprehensive and is available for both Android and iOS operating systems. You can download it directly from the official stores here:

The main menu will display a list of your UHome devices. If you have multiple homes and use this system, you can manage and monitor both from the same app. If you go into your installation, you can see everything happening in your home in real time, including the power supplied by solar energy, the grid, and the battery charge or discharge. You can also access all the photovoltaic energy graphs, the load on load, the grid load, as well as the battery charge percentage and the energy supplied or stored.

In the ” Settings ” section , we can configure the maximum photovoltaic power, the maximum battery capacity, and display the temperature unit in degrees Celsius. We can also see if there are any warnings on the device in question. In the “Device Details” section, we can see the name we gave it, the serial number, time zone, firmware version, inverter model (5K, which is 5kW of power), as well as different software versions, private IP address, Wi-Fi network to which we have connected it, etc. In the “Data Report” section, we will see the same graph we saw previously with the consumption statistics.

In the “Detailed Device Information” section, we can see the battery status (voltage, current, power, and battery charge), the status of the photovoltaic system with its two strings (voltage, current, and power), and in “Load,” we see the backup and bypass status in terms of voltage, current, and power, as well as the grid status (external electrical network). All the detailed information on the power status is available in this menu.

Other settings include setting the time zone and making a comment to the company to report any issues we may have.

One of the options we like most is ” Home Assistant ,” which is very easy and quick to integrate into this home automation system. Simply install the MQTT server in Home Assistant, configure it correctly, and enter the server URL, port, and username and password in the app. When you click save, Home Assistant will automatically receive the information, create the entities, and begin storing all the data provided via MQTT. The simple, native integration with Home Assistant via MQTT (configurable in just a few minutes and with automatic creation of 9 entities) is a notable technical advantage, allowing for detailed monitoring and the creation of custom automations.

If we go to the ” Device Parameter Configuration ” section and enter the password, we can configure the operating mode. This configuration is the same as we saw online, and we can also do it through the touchscreen. The three modes are: load matching mode , which is the default and recommended option for self-consumption; peak-valley arbitrage mode (to recharge the battery during off-peak hours and supply light during peak hours); and backup power mode (always keeping the grid battery charged in case of a blackout)

As you can see, the app will allow us to view the overall status of the power system, make adjustments to the operating mode, and configure MQTT to send information to Home Assistant. If you want to configure advanced parameters such as depth of discharge (DOD), you’ll need to use the touchscreen.

Integration into Home Assistant

Integrating NEWBATT UHome into the Home Assistant home automation system couldn’t be easier. The first thing we need to do is download and install the MQTT server via ” Plugins .” Once we’ve done this, and created a user on that server, we can configure it through the application as indicated above. After a few seconds, we can see all the entities that were automatically created for us in the ” Entities ” section. We don’t have to create the entities ourselves manually in a file; they will be created automatically. The entities it will create are the following:

• Solar : power in W and also voltage in V.
• Grid : power in W and also voltage in V.
• Load (backup) : power in W and also voltage in V.
• Battery : power in W, voltage in V, as well as the battery charge percentage in %.

In total, it creates 9 entities to perfectly monitor all parameters. Thanks to this, we can monitor, for example, if there’s a power outage. We can create an automation so that if the grid voltage drops to 0, it will alert us via Telegram or any other means. We must remember that if you have the entire home in backup, you won’t really notice the power outage, unless you have something “out” of backup

If we create a card with the list of all entities, we can see something like this:

All this information is updated every few seconds; it will only update what really needs updating. This is perfect for keeping a good history of everything happening in the power system.

Thanks to the integration of NEWBATT UHome into Home Assistant, we can monitor all the main parameters in detail, create graphs, and even integrate it into the home automation system’s Energy dashboard.

This is the end of our full review of the UHome Series, an energy system that will save us money on our electricity bills, but above all, will allow us to keep our homes powered even during a major power outage, all thanks to the modular batteries it includes. Now let’s move on to our final conclusions, highlighting the strengths and weaknesses of the device.

Final conclusions

The NEWBATT UHome Series is a great option for truly self-consuming your home . The inverter manages the energy generated by the solar panels to provide electricity for your home, and any excess energy recharges the battery when there’s no solar power (at night). This is perfect for making the most of every last kWh and saving on your electricity bill. People who buy these types of energy systems don’t do so just to save on their electricity bills, but also to always have electricity at home thanks to their backup system, which allows them to use batteries in the event of a power outage.

With the massive blackout that occurred in Spain on April 28, 2025, many people with solar panels in their homes realized they were useless because their inverters weren’t configured in island mode to isolate them from the grid. Furthermore, many people with batteries in their homes couldn’t power their power due to poor configuration and installation. This system comes equipped with everything—the inverter, BMS, and modular batteries—in a single unit, unlike other solutions that consist of several separate modules wired together.

Depending on your power needs, we have inverters from 3kW to 8kW , and we can also install batteries in 5kWh modules . The most important thing when deciding on this type of system is to buy an inverter with plenty of power. For example, if you have contracted 3.5kW of power at home, it’s ideal to buy the 5kWh inverter to give yourself even more headroom and avoid problems. Batteries can be added later without making any changes to the installation. Add one, configure the inverter to recognize it, and that’s it.

The fact that a hybrid inverter has a touchscreen to view the overall status of the home, and also to make advanced adjustments, is something to keep in mind. We don’t need internet access or a smartphone; we simply approach the inverter, configure the desired parameter (such as the battery depth of discharge), and that’s it. Via the web and the app, we can only view the overall status of the equipment in terms of solar, grid, load, and battery, as well as configure the operating mode, which we normally shouldn’t touch. What we liked most is that we can send the data to our Home Assistant via MQTT , which is perfect for monitoring all the energy in our home automation system.

However, not everything is perfect with this NEWBATT UHome Series. In terms of the features of the equipment and the inverter, we believe it has everything necessary to function perfectly, but we miss the software (web and app management) with more configuration and customization options. The configuration options we have on the touchscreen should also be available via the web and app. We find the website design too “busy”; we think they should redesign it to display the information much better and in a more user-friendly way. Some settings we miss are that we cannot define the maximum battery charge ; normally, the charge would be limited to 90% or 95% to increase its durability, but it always charges at 100%. When we use the battery charging mode from the grid, we cannot define the maximum charging power; the installer does it, and we do not have access to that parameter.

In terms of price including installation (verified in June 2025), the NEWBATT UHome Series system with 5kW power and 10kWh battery (two modules) is around €6,800 . A configuration comparable in specifications to the Huawei SUN2000 system (5KTL-L1 hybrid inverter + LUNA2000 10kWh battery + BMS + Smart Meter) is around €8,000 . In addition to the initial financial savings of approximately €1,200, NEWBATT offers advantages such as faster backup switching, a more compact system, and a much more versatile system.

• Truly compact power system, without the need for additional wiring between batteries and BMS with inverter, as is the case with other brands.
• Photovoltaic power input from two strings of up to 14A current intensity.
• It allows a LOAD charge (backup or critical loads) of up to the inverter power, in our case, up to 5kW, although in reality it allows up to 10% more margin.
• In the event of a power outage, the backup switchover time is less than 20ms, so it truly acts like a giant UPS; we won’t notice a power outage in the home.
• It includes Wi-Fi for status monitoring and some adjustments, including MQTT support.
• Compatible with Home Assistant via MQTT, we can receive the status of the solar, grid, load, and battery in entities automatically created by the system.
• Price: The price-performance ratio of this solution is very good, cheaper than the equivalent Huawei brand.

Weak points

• The configuration options via the web and app should be more extensive, at least the same as those on the touchscreen to avoid having to physically access the inverter for certain settings.
• Lack of user-configurable charge limit: A maximum charge percentage (e.g., 90–95%) cannot be defined for the battery via standard user interfaces. Although LiFePO4 batteries are robust, this option could further optimize their long-term lifespan for advanced users. Currently, charging is always performed at 100%.
• The maximum battery charging power from the grid (in arbitration mode, for example) is configured by the installer and is not easily adjustable by the end user.

After more than three months of exhaustive testing, the NEWBATT UHome Series is positioned as a solid alternative. In aspects such as backup speed and the small size of the all-in-one system, it is clearly superior to other popular options such as Huawei. This device is ideal for home environments, but also for small and medium-sized offices, with the possibility of installing solar panels for self-consumption to save electricity, as well as for the UPS (Backup of critical loads) function. Considering the technical characteristics, user experience, and price of the device, RedesZone’s final rating is 9/10, as follows:
