    Product Description

    10-35 kWh BSLBATT HV Storage B-BOXHEV

    The newly designed system provides easy connector to save valuable time for installaters. The stacking system provides flexible configurations from 204.8V to 614.4V voltage and 10.24 kWh to 30.72kWh capacity. The high power DC-coupled ESS battery of BSLBATT converts energy more efficiently than the AC-coupled ESS battery. As a result, BSL-BOXHEV can achieve higher efficiency.

    In addition, the BSL-BOX-HEV can be connected to your three-phase inverter to provide emergency power capabilities to protect your customer's home in the event of a sudden power outage, allowing your home to increase its independence from the grid and providing you with greater flexibility to change your system to meet demand in the future.

    The BSLBATT storage systems capture excess solar energy to provide power when it is needed most—when the power goes out, when electricity prices spike, or when the sun isn’t shining. BSLBATT curates a portfolio of hardware options from internationally recognized battery and power electronics suppliers in order to provide homeowners and businesses with safe, reliable, and renewable power.

    As one of the top lithium ion solar battery manufacturers, we can custom different specification batteries. Voltage: 12 to 48V; capacity: 50Ah to 600ah.


    “BSLBATT batteries eliminated the most difficult challenges we face when building microgrids in remote tropical locations. The batteries are much easier to transport and they have a good chance of lasting the entire 20 years. This means BSLBATT batteries generally pay for themselves in under 4 years!”
