SUNNY CENTRAL 250U/500U

Perfect for commercial systems in North America
 
The two proven central inverters are ideally suitable for commercial plants in North America: The integrated transformer makes possible direct connection with the low-voltage grid and, thanks to the outdoor enclosure with the OptiCool cooling concept, the devices can be installed practically anywhere. The leading edge efficiency of 97.5 %, which is remarkable for transformer devices, is just as convincing as the simple monitoring and remote maintenance via the integrated data logger – optionally with RS485, Ethernet or OPC interface. Special highlight: when others switch off, the two Sunny Central inverters continue to feed at a lower output. This means that in the temperature range of 122 to 140 °F (50 to 60 °C), up to 75 % of the nominal output is still available.
