What are the functions of solar inverter?

• Initiative operation and stop. in the morning after sunrise, solar radiation intensity strengthen; gradually, the output of solar cells also increase, when the power reach the inverter required output power, then the inverter starts operation initiatively. During operation, the inverter monitors solar cell module's output in every moment, as long as the output power of the solar cell module is greater than the inverter's required output power, the inverter will operate continuously until sunset shutdown, the inverter can operate even in rainy days. When the output of solar modules becomes smaller, the inverter output is close to 0, the solar inverter will in a standby status.
• Maximum power point tracking (MPPT). the output of solar cell modules is changeable according to solar radiation intensity and the solar cell modules' temperature. As the voltage of solar cell modules decreases when current increases, thus there is a best point of maximum power. The solar radiation intensity is changeable, obviously the maximum power point is also changeable. Related to these changes, make the solar cell modules in the maximum power point, the system obtains the maximum power output from the solar cell modules, which means MPPT control. The most important feature of the inverter in solar power system is integrated maximum power point tracking (MPPT) function.
