Waaree WEM 7500 Solar Off-Grid PCU Price Specifications

Waaree WEM Solar Off-Grid 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. 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 from the house of Waaree has the intelligent feature to recognize the type of battery connected to it. It may be an ordinary battery or a branded one, a tubular battery or a sealed one. No matter what the type, it auto adjusts the battery’s charging characteristics accordingly. Even those batteries which cease to go over 13.5V after a while of use work flawlessly with Waaree ’s Home UPS.
