Three-phase string inverters

Designed for commercial usage, this three-phase inverter is highly unique in its ability to control the performance of the PV panels, especially during periods of variable weather conditions.

This transformerless device has two independent MPPTs and efficiency ratings of up to 97.7%. The wide input voltage range makes the inverter suitable to low power installations with reduced string size. It is available with an optional fully-integrated DC switch, fuse and remote controlled DC disconnect function.
