Description

technical field

[0001] The invention belongs to a circuit device or system for power supply or distribution; an electric energy storage system, and in particular relates to an improvement of a circuit device structure of an AC main line or an AC power distribution network. Background technique

[0002] At present, the application of photovoltaic power generation system can be divided into the following two categories: independent off-grid photovoltaic power generation system and grid-connected photovoltaic power generation system. The former is not connected to the public grid, and the battery is charged through the output inverter controller or the output electric energy is directly supplied to the user load. Its common application is to provide electric energy for special places such as remote mountainous areas or areas without grid power supply, border posts, and weather stations. Different from the independent off-grid photovoltaic power generation system, the grid-conn...
