Ac’s went off

In the heart of hot day my ac’s stopped. Flipped breaker at post and they came back on. Quit again 15 minutes later. Powerline control said no service. Flipped circuit breaker at post and all have been runnig full tilt (3) for about 2 hrs. Initially upon resetting the power control showed i was drawing 50 to 51 amps. It moved. After things cooled a bit it showed 36-37. They were set on auto. Were my 3 units just too much demand until they had cooled things. Initially it was cool went they shut dow. We stepped away while they were running and when returned they were off. Any advice to avoid this is always useful. Sun was beating hard and the later sun was on front of coach. 2013 Itasca Elipse.

    We are you that you need 3 AC's running? We are 36' and 1 AC keeps it 75 in here when it's 95 and we are sitting in the sun. We keep the windshield curtains closed and any place else that will block the sun. Vent pillows to keep the cool air in and the sun's heat out. Awnings out to keep the sun off the sides. If you are going to be in a hot climate all summer I think you need to get some sun shades in place.

    Just 3 a/c units drawing 15 amps each and your inverter using another 5 or 6 amps puts you at a critical point for that 50 amp pole breaker

    Good idea. Will have them all cleaned soon. I don’t do ladders and roofs anymore.

    Looking at today’s weather in Madison, he should just open the windows.

    When the power cuts out on an A/C unit, it needs to be off for at least a couple of minutes for the high pressure side to bleed off. If started right away there is a strain on the system.
    Most surge protectors have a delay when plugged in just for that reason.

    One thing you may wish to check if they seem to be drawing too much current.

    When was the last time you cleaned the condensers????? Mine will trip the 20 amp; branch breaker if I don't clean 'em after parking under cottonwoods .
