Looking for some help. I have a new system Completely OFF GRID (Generator back -up )with a sunny boy 6.0US-41 and two sunny island 60/48 inverters.
Do i need a grid guard code to set the sunny boy to off grid mode only and is the RS 485 piggy back cards required for both units to communicate for monitoring and Frequency shift. On sunny days the sunny boy pushes 90 amps regardless of what the sunny island is set at and then the sunny boy disconnects. As the battery is not near full i would think there is some communication error. I have exhausted all other SMA tech tips as they only over some models and not much for completely OFF GRID
Any help would be Great
