SolaX HS25 T-BAT-SYS-HV-S2.5 battery

SolaX T-BAT-SYS-HV-S2.5 – High-voltage, heatable, IP65 battery tower

The SolaX T-BAT-SYS-HV-S2.5 is a modular, high-voltage (HV) LiFePO₄ energy storage system designed for residential and small commercial hybrid systems. The tower can be assembled from 2 to 13 battery modules, allowing for flexible capacity increasesfrom 5.1 kWh to 33.2 kWh.

One of the system's biggest advantages is its built-in heating technology, which allows charging and discharging even inextreme temperature conditions (-30°C to +53°C), while IP65 protection makes outdoor installation safe. 

The Triple MCS0800 control unitis required for the first tower connection , and the T-BAT-SYS-HV Series Box is required for the second tower connection.

SOLARKIT reviews

The SolaX T-BAT-SYS-HV-S2.5 is one of the most reliable and configurable residential/home-capacity Solax energy storage systems.

The LiFePO₄ cells, IP65 protection, 45A charging/discharging capacity, and a lifespan ofover 6000 cycles combine to ensure that the system provides stable and efficient operation over the long term.

The battery tower is particularly recommended for:

• hybrid systems (SolaX X3-Hybrid, Solax X3 Ultra, X1-Hybrid compatibility),
  
  
• outdoor installation,
  
  
• systems operating in extremely cold conditions,
  
  
• users who wish to expand their storage capacity in the future.

Can it be used in off-grid systems?

Yes, the T-BAT-SYS-HV-S2.5 is suitable for off-grid operation with the appropriate SolaX hybrid inverter.

Which inverters is it compatible with?

The T-BAT-SYS-HV-S2.5 is only compatible with SolaX high-voltage hybrid inverters:

• SolaX X1-Hybrid 
• Solax X3 Ultra 
• SolaX X3-Hybrid 

It cannot be used with inverters from other manufacturers , as the system communication and HV BMS integration are closed and SolaX-specific.
