Características

ZGR SOLAR CTR 1250 / 1500 inverters have been specially designed to improve performance and reduce volume in medium-large solar plants. Threephase ZGR SOLAR CTR inverters from 1250 to 1500 kW stand out for their high efficiency.
Likewise, the range of ZGR SOLAR CTR 1250 / 1500 inverters offer high reliability and guarantee of operation. It should be noted that with these inverters
an unbeatable power density per unit of volume has been achieved, making possible a significant reduction in the space required for medium-large
solar plant investors.
Another important feature is its automatic reactive regulation and its communication capabilities between them and the centralized supervision and
control system. All its parameters are configurable locally and also remotely. ZGR SOLAR CTR 1250 / 1500 inverters are adapted to several regulations to meet the requirements for response to voltage dips without disconnection.
Moreover, container solutions are a perfect for medium-large-scale projects and are specially designed to meet the most demanding specifications and to operate under adverse environmental conditions.
