SMA Sunny Boy 7.0-US and Rule 21:

The Sunny Boy 7.0-US SMA inverter is one of the smart solar 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 7.0-US not only provides in depth monitoring data for the home, or business owner, but the SMA 7.0 also allows utilities access to accurate energy production levels from residential solar systems.

SMA smart connected inverter will streamline future grid functionality and limit power surges, voltage sags, and grid blackouts.
