MPPT charger controller | MPPT Solar Charger
Cosmic has developed micro charger controller based MPPT (Maximum Power Point Tracking) charger for solar panels from 1Kva to 100Kva. The micro controller scans the impedance of the circuit from maximum to minimum and finds the point at which maximum power is delivered and fixes the impedance at that point. MPPT solar charger provides 20% to 30% extra energy compared to conventional charges.
