The solar power generation system with hybrid and off grid inverters prioritizes the use of photovoltaic energy to power the load. When photovoltaic energy is insufficient, it can be supplemented by grid power or batteries. When photovoltaic energy is surplus, the energy will be stored in batteries or sent to the power grid to maximize the utilization of photovoltaic power generation and achieve profits. In addition, this hybrid parallel off grid inverter can set peak valley time periods according to customer requirements to achieve peak valley filling and maximize revenue. In the event of grid failure, solar energy can continue to generate electricity and switch to off grid mode to continue supplying power to the load.1.
