How to use off grid inverter?

The off grid inverter will use the maximum power point tracking technology to extract the maximum possible power from the solar panel. There is a complex relationship between solar irradiance, temperature, and the total resistance of solar cells, so the output efficiency will change nonlinearly, which is called the current-voltage curve. The purpose of maximum power point tracking is to generate a load resistance (of the solar module) to obtain the maximum power according to the output sampling of the solar module in each environment.
