The central inverters of the SOLIVIA CS and CM series are designed for use with all common types of solar modules and photovoltaic systems with power output of between 44 and 100 kWp. Thanks to their built in high frequency technology, these Delta inverters achieve a peak efficiency rating of 95.9 percent. Even at working temperatures of +50° C, the central inverters of the SOLIVIA CS and CM series help your solar modules reach the highest possible efficiency, even on hot days.

These central inverters have between four and nine separate racks. If one inverter rack fails, another is able to instantly take over its load, thus ensuring a system availability of over 90 percent. All CS and CM inverters are equipped with surge, temperature, short circuit and overload protection devices. In case the device still needs maintenance, an integrated DC load break switch allows the system to be easily disconnected from the electrical grid. The wide input voltage range of 400 to 900 V enables a wide variety of system configurations and this offers the highest possible flexibility in system design.
