1. Automatic operation and shutdown function: After sunrise in the morning, the solar radiation intensity gradually increases, and the output of the solar cell also increases. When the output power required for the inverter to work is reached, the inverter will automatically start running. After entering operation, the inverter constantly monitors the output of the solar cell modules. As long as the output power of the solar cell modules is greater than the output power of the inverter, the inverter will continue to operate; Until sunset, the inverter can still operate even on rainy days. When the output of the solar cell module decreases and the output of the inverter approaches zero, the inverter enters a standby state.

2. The output of the solar cell module with maximum power tracking control function varies with the intensity of solar radiation and the temperature of the solar cell module itself (chip temperature). In addition, due to the characteristic that the voltage of the solar cell module decreases with the increase of current, there is an optimal working point to obtain the maximum power. The intensity of solar radiation varies, and obviously the optimal working point is also localized. Compared with these changes, the working point of the solar cell module is always at the maximum power point, and the system starts to obtain the maximum power output from the solar cell module. This control is called maximum power tracking control. The biggest feature of the inverter used in the solar power generation system is that it includes the function of maximum power point tracking (MPPT).

In terms of energy storage, after more than a year of outdoor practical working conditions, the measured battery efficiency of lithium batteries is above 94%, the measured efficiency of flow batteries is 76.32%, and the efficiency of power type energy storage batteries exceeds 94%. The measured values can all meet the manufacturer's promised values.
