MNRon, I looked at the fault history and to be honest nothing looks out of the ordinary. Just the point when it switches from inverting to pass through from the generator that it just doesn't play well with eack other at times.
Here is how mine looked
H1 D 6 11:18
Inverting 12.8 -336a (this amp # is the locked rotor peaking from the A/C unit, I know the inverting at time of this happening would be around 10-15a normal minimum daily draw.)
BTS:77F
TFMER:122F
FETS:104F
There was a couple of older faults with amp being 110 upto 200a but from the same issue of inverting to generator pass through not playing well with each other. Since raising the load share incoming AC to 16a instead of 15a no more faults.
