The decision for a Cosun Solar Home Battery is also a decision for the highest standards in safety and quality that “Technology from Germany” stands for.


     In Passive cell balancing the excess charge was not made used of, hence it is deemed to be inefficient.
    Whereas in active balancing the excess charge from one cell is transferred to another cell of low charge to equalize them. This is achieved by utilizing charge storing elements like Capacitors and Inductors.
    Cosun use the most effective DC-DC Active cell balance which largely reduce operating and sleep mode self-consumption down to 30mA and 9uA
