[RE-wrenches] OutBack 2024 troubleshooting question

[Dave]

Wrenches,

 

Responding to a neighbors call for help troubleshooting their off grid PV
system with a ten year old OutBack 2024T  inverter I came upon a problem
that I don't recall seeing  before. I may have seen it but my semi-retired
brain cannot remember this particular problem. Issue is that the inverter
will not synchronize and charge with a seemingly good Honda 7000i generator.

.         Generator output as measured with Fluke 126Vac 59.99Hz 165Vac Peak
runs loads fine on its own

.         Connected through to OB2024 the typical 30 second delay before
transferring and charging happens per usual (Red LED blinks a couple of
times then stays off and Amber charging light blinks for the delay period).

.         Upon transfer 300 Watts of AC loads on inverter seem to run OK on
generator BUT generator output falls to 95Vac and no charging is initiated.
Hz stays good and there is no audible change in the generator performance
that I can tell. 

.         No  Red LED  error light on OutBack. Just Amber charging light is
on, but no charging happens (no rise in voltage and no positive amps showing
on a fully functional TirMetric meter). 

.         No Mate on this system and I did not have one in my truck.

 

Signed,

Easily stumped in Vermont
