  • Page 86 Users can set PV types, including Independent,Parallel and Constant Voltage. Independent: The factory setting defaults to Independent, when PV is input in parallel but set to standalone mode, PV generation will be unbalanced. Parallel: Commonly used for testing in parallel mode, two or three PVs are connected in parallel.
