Characteristics

The ZGR SOLAR CTRh 3300 modular inverters have been specially designed to take advantage of the performance and power density in medium and large PV plants.

It has a great power density per unit volume, making possible a significant reduction of space in the surface area required for the implementation of PV Inverters in utility-scale plants.

Another very important feature is its reactive power regulation and its capabilities regarding communications between inverters and centralized systems of control and supervision.

ZGR SOLAR CTRh 3300 inverters adapt to different regulations to comply with the requirements for response to voltage drops without disconnection. They are perfect for PV Utility projects Medium – Large scale and are speci!cally designed for operate under severe weather conditions.
