[RE-wrenches] Outback AC Backfeed Error

[William Miller]

Jon:



In the deep recess of my memory I recall this error code with FX
inverters.  It was caused by a stuck transfer relay.  You might open the
inverter cover and look for signs of smoke or arcing in the relay.



Good luck!

Hey wrenches,



I have a client who has a couple of the Radian 8048's and has an error code
of "AC Backfeed Error GS-1". 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."



However when this happened the generator wasn't running and it's an off
grid system. Is there a way that the master is looking to the slave as
another power source? The system had been running fine this week, auto
running the generator early morning and shutting down on its own.



Anyone seen something like this before? Thanks,



Jon Siegenthaler
