SUNNY CENTRAL- High Tech for solar power stations

We have developed the Sunny Centrals specially for use in large PV power stations and open-field plants. Hence they possess completely special properties. String monitoring, capacity for teamwork and the ability to feed into the medium-voltage power grid make them first choice for PV systems with homogenous structure.

The Sunny Centrals are easy to install - indoors as well as outdoors. With peak efficiencies of over 98 % they belong to the most efficient central inverters on the market. maximum reliability and durability furthermore ensures the greatest investment security.

Perfect for commercial plants in North America

The two proven central inverters are ideally suited for commercial plants in North America. The integrated transformer makes direct connection with the low-voltage grid possible and, thanks to the outdoor enclosure and OptiCool cooling concept, the devices can be installed practically anywhere. The peak efficiency of 97.5 percent is remarkable for inverters with transformers. Monitoring and remote maintenance is performed via the integrated data logger, which is accessible through modbus, RS485, Ethernet or OPC interface.
