    Product Description

    20-40 kWh BSLBATT HV Storage PowerGrid

    The newly designed system provides an easy connector to save valuable time for installers. The stacking system provides flexible configurations from 204.8V to 409.6V voltage and 20.48 kWh to 40.96kWh capacity. The high power DC-coupled ESS battery of BSLBATT converts energy more efficiently than the AC-coupled ESS battery. As a result, PowerGrid HVS can achieve higher efficiency.

    Residential Energy Storage System

    In addition, the PowerGrid HVS can be connected to your high-voltage three-phase or single-phase inverters 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 provide you with greater flexibility to change your system to meet demand in the future.


    home battery system

    The BSLBATT PowerGrid HVS is the ideal energy storage solution for on-grid or off-grid solar installations. Lower your utility bill by avoiding the need to buy electricity at peak times with the BSLBATT Lithium Battery PowerGrid HVS. With the BSLBATT 20 - 40 kWh residential HBattery bank, you can use more clean energy in a more efficient way. This makes you more independent of daylight and utility power.

    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!”
