Product description
Product description
The SolaX T-BAT-SYS-HV-S2.5 is a modular, high-voltage energy storage system developed for direct integration with SolaX inverters. The system is designed for residential and small business energy storage applications, featuring high efficiency, advanced safety solutions and easy installation.
Available versions:
- SolaX T-BAT-SYS-HV-S2.5 – 7.5 kWh
- SolaX T-BAT-SYS-HV-S2.5 – 10.0 kWh
- SolaX T-BAT-SYS-HV-S2.5 – 12.5 kWh
- SolaX T-BAT-SYS-HV-S2.5 – 15.0 kWh
- SolaX T-BAT-SYS-HV-S2.5 – 17.5 kWh
- SolaX T-BAT-SYS-HV-S2.5 – 20.0 kWh
The system is built from 2.5 kWh battery modules, which are connected in series in the high-voltage architecture. A set can be formed by combining 3–8 modules, so the capacity can be freely configured between 7.5 and 20.0 kWh. The system is controlled by the BMS-BOX-HV-S2.5 central unit, which manages the operation and communication of each module.
The built-in intelligent BMS monitors temperature, voltage and current at the cell level and ensures long-term stable operation with active cell balancing. The high-voltage (HV) design ensures high system efficiency and reduces energy loss during charge-discharge cycles.
The T-BAT-SYS-HV-S2.5 has an IP65 housing, making it suitable for both outdoor and indoor installation. The naturally cooled, fanless design ensures quiet and maintenance-free operation, while the operating range from -10 °C to +50 °C guarantees stable performance.
The system is fully compatible with the SolaX X1-Hybrid, X3-Hybrid and X3-Fit inverters and is integrated with the SolaX Cloud online monitoring platform. This enables real-time energy monitoring and remote diagnostics, ensuring easy operation.

How do I choose the right battery?
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?
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?
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?
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?
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.
