The functions of solar powered inverter
Solar powered inverter not only has the function of direct AC conversion, but also has the fuctions of maximize solar cell and system maintenance. Here we introduce the functions of active operation and shutdown , and maximum power point tracking briefly.
1.Active operation and shutdown
After sunrise in the morning, the intensity of the solar radiation is gradually strengthened, and the output of the solar cell increases. When the output power of the inverter is reached, the solar powered inverter is active. After entering the operation, the inverter will always look after the output of the solar cell module, as long as the output power of the solar cell component is greater than the output power of the inverter need, the inverter will continue to run;
until sunset, the inverter shut down. The solar powered inverter can run even if the rainy day. When the output of the solar cell module becomes smaller, the output of the inverter is close to 0, the inverter will enter the standby mode.

2.Maximum power point tracking(MPPT)
The output of the solar cell module is changed with the solar radiation intensity and the temperature of the solar cell component itself (chip temperature). Because other solar cell module has the characteristic of the voltage decreases with the increase of current, thus has the best task point can reach the maximum power. The intensity of solar radiation is always changing, and the most obvious point is in the transition. With regard to these changes, make the solar cell components always reach the task point at the maximum power point, the system obtain maximum power output from the solar battery components, this control is the maximum power point tracking. The biggest feature of the solar panel inverter is the maximum power point tracking (MPPT).
