We are introducing an advanced ALFA+ Solar PCU that is mainly used in Hospitals, schools, industries petrol pumps, banks and also in home. PCU means Power Conditioning Unit, is an integrated unit consists of grid charger, inverter, MPPT solar charger. Alfa + solar PCU continuously monitor battery and solar voltage as well as grid and output voltage with their current.

MPPT based solar charge controller extracts the maximum power from the solar panel whereby it increases the efficiency of the system. In Alfa+ Solar PCU MPPT charger has multi stage charging which maintains the battery charging voltage such that it increases the life of solar battery.


PCU means Power Conditioning Unit which uses solar power energy in first priority and grid (government electricity) in second priority to charge the solar batteries. Since usage of power from grid in Alfa+ Solar PCU is secondary, grid power is only used when solar energy isn't present and battery voltage level reduces to 11.5V/Battery (Default 11.5V, Configurable). Grid power is also needed when solar power generation is less and battery voltage is reduced to 11.5V/Battery (Default 11.5V, Configurable).
