Sunny Central 250U, 500U, and 500HE-US Inverters

The Sunny Central 250U and 500U include integrated isolation transformers and deliver 97% CEC-rated efficiency. The Sunny Central 500HE-US couples to an external medium voltage transformer to accommodate long distance power feeds to distribution substations. The user interface features a large LCD screen that provides a graphical view of daily plant production and the status of the PV array, inverter, and utility grid. With SMA's OptiCool temperature management system, the units can be operated in ambient temperatures of up to 50°C (122°F).

The Sunny Central product line also offers a variety of remote monitoring options. Users can choose from RS-485, Ethernet, or wireless communications via Bluetooth or GSM with the optional WebBox. Daily performance data can be automatically uploaded to the free Sunny Portal website (www.sunnyportal.com). Optional Sunny Central String-Monitor-US smart combiners enable string level monitoring. The accuracy of performance data can be increased by using the optional Sunny SensorBox, which provides monitoring of local irradiance, temperatures, and wind speed.

All Sunny Central inverters are UL Listed to UL 1741 for the U.S. and Canada / IEEE-1547 compliant.
