A new generation of home and commercial energy storage is arriving soon at PV Solar Store.

A new generation of home and commercial energy storage is arriving soon at PV Solar Store. The Solax T-BAT-SYS-HV-R2.5 is a high-voltage battery solution designed for users who want reliable performance, flexible expansion, and intelligent system management—all in a compact, installation-friendly package.

Built on proven LiFePO₄ (LFP) technology, the T-BAT-SYS-HV-R2.5 offers exceptional safety, long cycle life and high system efficiency. With a modular stackable design ranging from 5.1 kWh to 33.2 kWh per string , it is perfectly suited for both residential hybrid systems and small commercial applications seeking scalable and dependable energy independence.

High Performance with Long Cycle Life

The T-BAT-SYS-HV-R2.5 is engineered for strong, consistent performance even under demanding daily cycling.
According to the datasheet:

  • Maximum 50 A charge/discharge current for fast and efficient cycling
  • Cycle life greater than 6,000 cycles, ensuring long-term value
  • Battery round-trip efficiency up to 95% (module-level)

Each TP-HR25 module provides 2.56 kWh total energy (2.3 kWh usable) with 99% faradic charge efficiency —ideal for daily solar charge and discharge operations.

Assured Safety & Reliability with LFP Technology

Safety is a core feature of the T-BAT-SYS-HV-R2.5.
The system uses LiFePO₄ battery cells (50Ah), chosen for their:

  • superior thermal stability
  • absence of toxic heavy metals
  • long lifespan
  • excellent performance across a wide temperature range

The system is certified for operation between -20°C and +50°C (discharge) and 0°C to +50°C (charge) , making it suitable for European climates and controlled indoor locations.
