• New Installation Assistant with direct access via smartphone minimizes time in the field
• Integrated disconnect simplifies equipment stocking and speeds installation

Unmatched Flexibility
• SMA’s proprietary OptiTracTM Global Peak technology mitigates shade with ease
• Multiple independent MPPTs accommodate hundreds of stringing possibilities

Trouble-Free Servicing
• Two-part enclosure concept allows for simple, expedited servicing
• Enhanced AFCI technology reduces false tripping while improving sensitivity in real arcs, greatly reducing unneeded service calls

SMA Sunny Boy 3.8 and Rule 21:

The Sunny Boy 3.8 SMA inverter is one of the smart inverters approved by Rule 21. California’s new Electric Rule 21 was created to ensure a safer, more reliable grid by facilitating a bidirectional communications link between the inverters and the utility. Therefore, the Sunny Boy 3.8 not only provides in depth monitoring data for the home, or business owner, but the SMA 3.8-US also allows utilities access to accurate energy production levels from residential solar systems.

This smart inverter-utility interconnectivity will streamline future grid functionality and limit power surges, voltage sags, and grid blackouts.
