MPN N/A Categories: ,
SMA has updated its residential inverter line with its all-new Sunny Boy transformerless single-phase residential inverters. These new inverters now have up to three separate MPPT channels, allowing, even more, stringing choices. These inverters also now have an integrated DC disconnect, that simplifies and speeds installation. SMA’s unique Secure Power Supply feature has been improved, and now can supply up to 2,000 W (15 A / 120 VAC) of power to a protected outlet during a grid outage, for recharging portable devices or a small UPS directly from the PV array. Connection to the SMA’s Sunny Portal for solar array monitoring has also been simplified. These inverters now ship with an included datalogger, allowing both WiFi and Ethernet wired connection options for monitoring the solar array. These SMA inverters are listed to UL 1741, UL 1998, UL 1699B, and are compliant with IEEE-1547, and FCC Part 15 (Class A & B), as well as both ground and arc fault detection per NEC 2011. They are covered by a standard 10-year warranty, with 5 and 10-year extensions available.   SMA Sunny Boy Grid-Tie Inverters
