Solar PCU is similar to a solar inverter, there are a few differences. In a solar PCU, solar charging of battery takes priority during the day. The Solar PCU controls the priority and optimally selects the source of charging. It comes with user selectable energy saver mode which allows the user to select the priority and save the bill. It also selects the source of AC output to be either from the Solar or inverter or the grid. In the Energy Saver Mode priority is given to Solar, the battery is charged first and also supports the inverter to power the appliances. Once the solar energy stops, the PCU starts consuming the stored energy from the battery. Once the stored energy is used to a particular level, the inverter switches to grid. The main focus here is to save the electricity bill cost.
