SolaX TSYS-HS51 5.1kWh HV Heated energy storage

SolaX TSYS-HS51 – 5.1 kWh stackable, high-voltage LFP heated battery

The SolaX TSYS-HS51 isa 5.1 kWh high-voltage (HV) LiFePO₄ battery module, which is the basic building block of the TSYS-HS51 battery tower. The module does not operate on its own; the system is controlled by the TBMS-S51-8 BMS, which allows for the construction of towers with a total capacity of up to66.5 kWh.

The TSYS-HS51 module is suitable for outdoor and indoor installation, has IP66 protection, and uses built-in battery heating technology to ensure safe charging even in extreme cold.

Its high level of safety, service lifeof over 6000 cycles, and parallelizable, expandable system make it the ideal choice for larger residential, commercial, or industrial energy storage projects.

SOLARKIT reviews

The TSYS-HS51 module is SolaX's most advanced and reliable HV battery technology:

• LFP (LiFePO₄) chemistry → the safest, longest-lasting cells
  
  
• IP66 protection → fully outdoor compatible
  
  
• Battery heating down to -30°C → adequate charging even in winter
  
  
• Modular expandability → 2–13 modules, up to 66.5 kWh
  
  
• CAN + RS485 communication → stable, inverter-integrated operation

If you are looking for a reliable, safe and long-lasting energy storage solution for your SolaX Hybrid system, the TSYS-HS51 is one of the best choices in its category.

Can it be used in island mode?

Yes, the TSYS-HS51 fully supports off-grid operation in combination with the appropriate SolaX Hybrid inverter.

The module does not function as a stand-alone battery.

What controllers and systems is it compatible with?

The TSYS-HS51 only works withthe TBMS-S51-8 BMSsystem.

The TBMS-S51-8 controls the operation of the entire tower, so the TSYS-HS51 module cannot be used on its own.
