DC Combiner box for 48V / 51.2V Solar Battery
The BSLBATT Battery DC combiner box is a core component designed for low-voltage energy storage systems, designed to safely and efficiently connect up to eight individual low-voltage battery packs (groups) in parallel to flexibly expand total system capacity and improve power supply reliability. It simplifies the wiring connections of the battery system, provides critical safety protection, and is ideal for building modular, scalable, and highly reliable 48V / 51.2V energy storage systems.
6kWh Solar PV Battery Storage
The BSLBATT 6kWh Solar Battery utilizes cobalt-free lithium iron phosphate (LFP) chemistry, ensuring safety, longevity, and environmental friendliness. Its advanced, high-efficiency BMS supports up to 1C charging and 1.25C discharging, delivering a lifespan of up to 6,000 cycles at 90% Depth of Discharge (DOD).
Designed for seamless integration into residential, commercial, and industrial energy storage systems, the BSLBATT 51.2V 6kWh rack-mounted battery provides reliable and efficient power storage. Whether you're optimizing solar self-consumption in a home, ensuring uninterrupted power for critical loads in a business, or expanding an off-grid solar installation, this battery delivers consistent performance.
