Characteristics

The ZGR SOLAR STRci string inverters are easy-to-use devices that have been designed to meet the energy needs. Given its power, they are ideal for commercial and small industrial self-consumption, where the aim is to reduce the consumption of the electrical grid.

In an effort to improve the performance of solar plants, these inverters offer high energy performance of over 98%. The ZGR SOLAR STRci inverters are equipped with an LCD display, to provide the user with easy access to inverter information and its parameters.

This new range of inverters achieves the maximum utilization of the energy delivered by the photovoltaic panels by handling multiple MPPT of the inverter string and offers a wide DC input voltage range between 200 and 1000 Vdc; and a rating of protection IP 66.
