I was still thinking AGS and Dometic thermo control.......but no AGS; no Dometic. So gen basically dies when the air conditioner reaches set point temp (compressor shuts off). The compressor shut off should create a sudden current drop and simultaneous AC voltage increase on the gen output.......so perhaps the gen control board is responding (for some reason) with a shutdown, but normally that should not be an issue. Any fail codes created with this shutdown at the generator?
Short cycling the compressor (if it tries to restart very quickly after just turning off) could create very high AC load currents, which you would think would trip either the gen breaker or the air conditioning breaker. Since that is not happening short cycling probably not happening either. Just thinking out loud here.
The other strange issue is the 20-60 minute time to be able to manually restart the gen. When the gen stops the transfer switch should disconnect and transfer back to shore connections (even if you are boondocking), so trying to restart the gen should be easy since it would be unloaded. If the transfer switch is not switching off the gen output feed then perhaps the gen is trying to restart under load? This is a stretch, but turn off air cond and converter and try to restart the gen after one of these air conditioning compressor temp reached cycles. If the gen still does not start there must be a gen issue perhaps resulting from being hot and trying to restart......nothing to do with the air conditioning other than being a 1.5kw load on the gen. So flakey fuel pump etc. ? What happens if you just start and run the gen with no air conditioning at all until the gen is hot and then shut off manually......does it restart without issue?
Time to grab my "beauty sleep"......some more thinking and testing things required on this one.
