SMA · Sunny Boy Inverters
The Sunny Boy inverter has either disconnected from the grid or is limiting its output to 6 kW (adjustable) over a 10-minute average. This occurs in a three-phase system with other Sunny Boys and an SMA Power Balancer, specifically to prevent unbalanced loads when another inverter detects a fault or grid issue.
Click steps to track your progress.
Check other Sunny Boy inverters in the three-phase system for any fault messages or disconnections.
Your installer can check the 'PowerBalancer' operating parameter settings (PhaseGuard, PowerGuard, FaultGuard).
Consult your installer to ensure the system configuration is correct and address any underlying faults in the multi-inverter setup.
