InfiniSolar V III TWIN
High PV voltage range
InfiniSolar V III is an upgraded version of our InfiniSolar V second generation. This third-generation inverter can accept a high PV voltage range and this feature will facilitate PV system installation. InfiniSolar VIII also comes with a built-in Wi-Fi function, mobile monitoring can be carried out through mobile applications. Besides, the battery independence feature will keep the inverter running whether the battery is connected or not. We also offer a parallel operation function for up to 9 units. It provides high flexibility for future power expansion.
