[RE-wrenches] Outback AC Backfeed Error

[jay]

HI Jon,

Can you tell us how long the system has been operational?  Trying to figure out if this is a new system or an older.

And what size generator do you have? 

If its an older system and with a big generator/big loads then there is a possibility of damaged/sticky relays.

Looking at the manual it states that "Usually indicates another AC power source (out of phase with the inverter) was connected to the unit’s AC output. Can also occur if an out-of-phase AC source is connected to the inverter’s AC input."
