SUNNY CENTRAL 250-US / 500-US

SUNNY CENTRAL 250-US / 500-US

Perfect for commercial systems in North America

The Sunny Central 250-US and 500-US solar inverters are ideally suited for commercial projects in North America. The integrated transformer makes direct connection with the low-voltage grid possible and, thanks to the outdoor-rated enclosure and OptiCool™ temperature management system, the units can be installed practically anywhere. The CEC efficiency of 97 percent is remarkable for transformer based inverters. Monitoring and remote maintenance is performed via the integrated data logger, which is accessible through RS485, Ethernet or OPC interfaces.
