Home > News & Events The efficiency of the PV inverter

PV inverterconversion efficiency of the inverter means electrically converts solar panels issued power efficiency. Plays the DC inverter solar panels into alternating current emitted and transported them to the role of the AC power company grid. High conversion efficiency of the inverter, for their own use and sale of electric power can be increased.

There are two factors that determine the efficiency of the inverter. First, when the direct current into alternating sine wave, you need to take advantage of the use of power semiconductor circuit of direct current for switching process (a very short time and turned off), then the power semiconductors will generate heat, resulting in losses. By improving the switching circuit design, it can minimize this loss. Another factor is experience with inverter control to improve efficiency. Output current and voltage of the solar panels will be as sunlight and temperature changes in time, the inverter may be the best current and voltage control, so as to achieve the maximum amount of power (power point). In the short period of time to find the optimum power point, the conversion efficiency will be higher.

This inverter control characteristics, the manufacturers of the products are different, the conversion efficiency is also different. Some high conversion efficiency of the inverter even though the maximum power output, but low power output when the conversion efficiency is very low; there is the power output from low to high power output has maintained an average conversion efficiency. Thus, the choice of the inverter, and the need to consider the solar panels is provided between the output of the matching characteristics.
