Product description

The SolaX S51 BAT is a 5.1 kWh lithium iron phosphate (LFP) battery module that is the base unit of the manufacturer's HS51 high-voltage energy storage system. The modules can be stacked on top of each other, allowing for flexible expansion of the total capacity from small residential applications to industrial scale.

Capacity: 5.1 kWh per module
Cell technology: LFP → safe, long life (>6000 cycles)
Protection: IP66, for both outdoor and indoor installation
Multiple modules can be combined: 2–13 pieces → 10.2–66.5 kWh capacity

The module is stackable, saving space and allowing for quick installation. It also supports the mixed use of old and new batteries (plug & play connection, lossless), making it easy to expand. The version with heating function allows use in environments down to -30 °C, which is particularly beneficial in cold climates.

Safety is ensured by multi-layered protection and an aerosol fire extinguishing module that is automatically activated when necessary. This provides industrial-grade safety even in residential installations.

Modular expandability from 10.2 to 66.5 kWh.
It can be expanded with a mix of new and old modules.
Built-in heating function (optional model).
Aerosol fire protection for maximum safety.

Compact, easy-to-install stack system. The SolaX S51 BAT is a flexible, safe and future-proof battery module, which, as part of the HS51 system, is an excellent solution for increasing the energy independence of family homes and small industrial facilities.

Do you have a question?

How do I choose the right battery?

The most important thing is that the battery fits your inverter and the performance of your system. It is worth considering how much capacity (kWh) you need and whether you want to expand the system later.

Always check the inverter's technical data sheet, as it will tell you which batteries it is compatible with. For example, Huawei inverters only work with Huawei batteries, while Deye inverters can be connected to multiple manufacturers, offering a more flexible solution.

How do inverter types differ?

The lifespan of modern lithium batteries is usually 10–15 years, depending on usage and temperature conditions.

Manufacturers typically give an expected lifespan of 6,000–8,000 charging cycles – this can mean up to a decade and a half, assuming one cycle per day.

What happens in the event of a power outage?

If the inverter supports backup (stand-alone) operation, it will automatically switch to the battery during a power outage, so the most important consumers continue to operate.

It is important to know that if there is no backup function, the system will completely stop in the event of a power outage, even if the solar panels are producing. This is because most on-grid inverters cannot operate without mains voltage for safety reasons, so they cannot supply power or charge batteries.

What warranty does the battery have?

Depending on the manufacturer, batteries come with a 5 or 10 year warranty, and for some models this is also tied to the number of cycles. We indicate the exact warranty period on each product page, so you can always see how long the manufacturer's warranty lasts before you buy.

What happens if the battery fails?

If the battery is not working properly, it is a good idea to first have the problem diagnosed by a professional to rule out incorrect setup or installation. It is possible that the problem is not with the battery itself, but with a non-activated function or communication setting.

If it is proven that there is indeed a problem with the product, you should contact the manufacturer's or distributor's customer service, who will assist you in the troubleshooting process and the warranty administration process.
