SMA Sunny Boy 3.8kW 208/240VAC TL Inverter, SunSpec Compliant, SB3.8-1SP-US-41
The SMA Sunny Boy SB-41 series of transformerless single-phase residential inverters can be used for both residential single-phase applications. These inverters utilize multiple independent MPPT channels, allowing more stringing options. The integrated DC disconnect simplifies and speeds installation. Solar array monitoring through SMA’s Sunny Portal has also has been simplified, as these inverters ship with factory-installed WiFi capable data loggers that enable fast and easy connection to the Sunny Portal platform, and can be field configured via a laptop, smartphone, or other WiFi-enabled devices.
SMA’s unique Secure Power Supply feature has been improved, and now can supply up to 2,000 W of opportunity power in the event of a grid outage, as an increased value-add opportunity.
Power+ MLPE devices with the ROOFCOMKIT-P2 can be utilized for states that have adopted NEC2017 code to provide module-level optimization, shade mitigation, and/or rapid shutdown functionality, based on needs and price point. These inverters are now Sunspec compliant, and can also use the new TS4-R-F MLPE devices to comply with NEC2017 module-level RSD, without needed the ROOFCOMKIT. In states still enforcing NEC 2014 code, the SMA Rapid Shutdown Boxes and Controller can still be used.
