In the case of an Off-Grid Solar System, Power generated from the rooftop system is stored in a battery bank and then fed to load as and when required. Both types of applications AC and DC can be connected to this system. The inverters are smart and can optionally use the grid power also to keep the load running when power from solar and battery bank is not enough to cater to the total load. Smart logic of the inverter will ensure that an uninterrupted power supply is available with bare minimum use of grid power.
