Hi Jennifer Ministries
As others have noted knowing which breaker is tripping would improve our ability to narrow down the issue & offer more accurate suggestions.
Without more info, I see 4 possible breakers involved depending on equipment installed.
Distribution panel Main breaker.
Distribution panel AC breaker.
Generator breaker.
EMS contactor (breaker)?
In my case the EMS contactor was opening on low voltage, the generators were still supplying power. A Micro-Air Easy Start device solved the issue and I can start & run the AC on a single EU2200i Honda with the fridge on electric & converter in trickle mode.
It will also interrupt the AC power should someone start the microwave, toaster, or coffee maker, etc. It will restore the AC once conditions improve.
The Micro-Air is $$$ but can be swapped into future AC units if a replacement becomes warranted.
