BSL Batteries 5.32kWh 51.2V LiFePO4 Wall Mount Battery

BSL Batteries offers a 5.32kWh 51.2V lithium iron phosphate (LiFePO4) wall mount battery designed for reliable energy storage in residential and small commercial solar applications. Built with stable chemistry and a compact form factor, this unit provides safe, long-cycle performance for daily charge-discharge operations in off-grid or hybrid solar systems.

The battery features a nominal capacity of 5.32kWh at 51.2V, delivering approximately 104Ah of usable energy. It uses LiFePO4 chemistry, known for thermal stability and a lifespan exceeding 6,000 cycles at 80% depth of discharge. The wall-mount design includes an integrated battery management system (BMS) that protects against overvoltage, undervoltage, overcurrent, short circuits, and overtemperature. Communication is supported via CAN and RS485 protocols for seamless integration with compatible inverters such as those from Sunsynk and other major brands.

This battery enables homeowners and installers to store excess solar energy for use during evenings or power outages, increasing self-consumption and reducing reliance on the grid. Its lightweight construction and wall-mount capability save floor space, while the modular design allows for parallel expansion to meet growing energy needs. The maintenance-free operation and wide operating temperature range make it suitable for diverse South African climates.
