Solar power generation is a new energy field that is energy-saving and environmentally friendly. It is a popular project so far.
For solar inverters, most people probably know solar energy and do not understand inverters, but with the improvement of science and technology, solar inverters have been widely used in our lives, including solar inverters.
Inverter refers to the conversion of direct current into alternating current (usually 220V, 50Hz sine wave).
Solar inverters can be divided into four categories: centralized, string, distributed and micro inverters.
Use exclusion. Unplug all the strings on the input side of the inverter, and then connect them one by one. Use the function of the inverter to start up to detect the insulation resistance to detect the faulty strings.
The core of the solar inverter device is the inverter switch circuit, referred to as the inverter circuit. The circuit completes the inverter function by turning on and off the power electronic switch.
