Sitting with 105 degree outside temperature, and running our three AC's here in Yuma, AZ. on 50 Amp shore power, as we Shelter in Place.
Then, Bam! everything shut down and I found the coach was now on inverter mode. Thus, no AC was available until I started the 12K Generator. The Generator ran all three AC's without issues. Then, I went outside to check out the issue.
Investigating, I looked at the Leviton Surge Protector and found that the two, normally green indicator lights were dark. Since I did not see a reset button on the protector, I decided shut everything down
