Excess current from damaging or reducing the lifespan of the battery when it is fully charged.
Prevents deep discharge
It disconnects the load when the battery is too low, helping avoid battery damage.
Regulates voltage and current
It ensures the solar panel output matches what the battery can safely handle.
Improves battery life
By controlling charging cycles properly, it helps batteries last longer.
Prevents reverse current flow
It stops electricity from flowing back from the battery to the solar panels at night.
