Inverter Fault
The yellow LED is on for 5 seconds, remains off for 3 seconds and then blinks 5 times.
The code is repeated 3 times. If the condition remains the code will continue to be sent.
The inverter has encountered an internal fault that prohibits normal operation and will
most likely require servicing.
Contact SMA America for assistance.
