Description Datasheet

SMA Sunny Boy > 6.0 kW 208 / 240 Volt Single Phase Grid-Tie Inverter

Sunny Boy 6.0-US with integrated DC Disconnect, LCD, Grey Lid, AFCI, 208 & 240VAC; SunSpec Compliant.

The SMA "-41" Series Sunny Boy inverter, featuring SunSpec signal transmitter chip, is one of the most versatile residential inverters available. Combine this series with the SunSpec certified JMS-F Rapid Shutdown MLPE (SMA JMS-F) in order to build cost effective NEC 2017 PV RSS compliant string systems. Or leave all the rooftop electronics behind and design the system to take full advantage of the Secure Power Supply (SPS feature not Compatible with Sunspec based PV RSS). 600V max system DCV, compatible with both 240V and 208V sites, and backed by SMA's Power+ customer service package.

NOTE: All SMA Sunny Boy -41 Grid-Tie inverter models are being discontinued by manufacturer, replacement models expected Q3 of 2023. Check local AHJ Requirements as these units do not have IEEE 1547-2018 which may be required in some states like CA, PA, NY and New England.

The SMA Sunny Boy SB-41 series of transformerless single-phase residential inverters can be used for both residential single phase 120/240 VAC applications, as well as for three-phase 208 and three-phase 240 volt applications, when used in groups of three inverters to balance the phases. These inverters utilize three separate MPPT channels, allowing more stringing options, and up to three array facings. The integrated DC disconnect simplifies and speeds installation. Solar array monitoring through SMA’s Sunny Portal has also have 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, smart phone, or other WiFi enabled device.

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, which provides a single ‘protected’outlet useful for recharging portable devices or a small UPS directly from the PV array.

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 customer 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.

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-year and 10-year extensions available.
