Abstract
The invention discloses a grid-connected photovoltaic power generation system for residential housings. The grid-connected photovoltaic power generation system for residential housings comprises photovoltaic cell panel assemblies and grid-connected inverters, wherein each photovoltaic cell panel assembly is independently connected with the input end of each corresponding grid-connected inverter. In the grid-connected photovoltaic power generation system for residential housings, each grid-connected inverter is independently connected with the corresponding photovoltaic cell panel assembly, electric energy generated by each cell panel can be normally converted and output, the output ends of the grid-connected inverters can be directly inserted into an electric socket to supply electricity to a load and can be connected in parallel to input all generated electric energy to an external power grid to be used, and therefore the grid-connected photovoltaic power generation system for residential housings can greatly improve energy utilization and conversion rate, is strong in practicality and can sufficiently use the photovoltaics to generate electricity.
