A: Solar panels В: Grid inverter C: AC cable D: AC power distribution box E: Electricity unit F: Low-voltage power grid
Description: Solar panels are connected to 1 piece of solar grid tie inverter. This micro inverter draws power electrical energy from the solar panels through maximum power point tracking (MPPT) function. After high-efficiency inverter conversion, the DC power of the solar panels is converted into AC power. The high frequency modulation and zero-phase offset technology are used to synchronize the connection with the solar micro grid and finally to realize the transmission of electric energy to the grid.
