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!”
