Inverter for photovoltaic systems

Sungrow SG3.0RT AFCI inverter* Product code: ST-3240

SunGrow are high-quality grid inverters used to convert electrical energy into direct current energy for the needs of photovoltaic PV systems. Inverters limit power output at high temperatures to prevent equipment damage. Therefore, a high-quality cooling solution is essential. The fans ensure the optimal temperature inside the inverter by adjusting their rotational speed to changes in ambient temperature.
