CENTRAL THREE-PHASE INVERTERS ZGR SOLAR CTR 150/300 inverters are specially designed to improve the performance of mediumlarge solar plants. ZGR SOLAR CTR inverters have been specially designed to improve performance and reduce volume in medium-large solar plants. The range of threephase inverters ZGR SOLAR CTR is 150 and 300 kW. Likewise, the range of ZGR SOLAR CTR inverters offers high reliability and guarantee of operation. It should be noted that with these inverters has been achieved an unbeatable power density per unit of volume, 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 inverters operate with a 3 x 400 V output voltage and are adapted to several regulations for compliance with the response requirements for voltage sags without disconnection.
