Characteristics

String inverters ZGR SOLAR STR are easy-to-use devices that have been designed to meet the needs of all solar power plants connected to the grid.
In an effort to improve the performance of solar plants, these inverters offer high energy efficiency, greater than 98%.
ZGR SOLAR STR inverters have an LCD display, to make it easier for the user to access the information of the inverter and its parameters.
This new range of string inverters offers a DC input voltage range between 480 to 800 Vdc and an IP 65 tightness rating.
