UTL Alfa Solar PCU 7.5 KVA 120V Price Specification

ALFA PCU is a Model of Power Conditioning Unit (PCU) which uses Solar (primary) and Grid (secondary), to charge the batteries. Since usage of power from grid is secondary, grid power is only used when solar energy is not 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).

MPPT based solar charger extracts the maximum power from the solar panels whereby it increases the efficiency of the system. MPPT charger has multistage charging which maintains the battery charging voltage such that it increases the lifespan of battery.PCU (Power Conditioning Unit) is an integrated unit consists of grid charger, inverter, MPPT Solar Charger. It continuously monitors Battery and Solar voltage as well as Grid and Output voltage with their currents.
