NEC allows six breakers to disconnect panel circuits. More than six requires a main breaker.
It is not a charger, it is a converter1

A loose connection in the circuit could cause low voltage which increases amperage. Go through 120-volt distribution panel, disconnect each wire, one at a time. Clean the copper,and re-terminate. Do this to both hot wires and neutral.

I'm on it!
Funny, I tell Mrs. I never see two same campers. We had a 2001 Outback 25 RSS we loved 20 years before this.

Add a Micro Air Easy Start. They delay the start up of the compressor until the blower fan is up and running.

I love mine. My A/C never has an issue starting on my EU2200

Your generator is likeky rated at sea level. Higher elevation reduces power output.

Considering the highest point in VT is a little over 4kft it’s highly unlikely that altitude is the culprit anywhere within a 2 day drive of his home, anywhere you’re gonna park a travel trailer.

I'll try disconnecting battery. I see no circuit labeled battery charger in the breaker panel, guess it is powered through the main breaker.


If you do that than all the 12V loads will need to be powered from the generator via the 120/12V inverter.
If you could disconnect the inverter, then any 12V loads would be supplied by the battery.

Oh boy….

OP, if it starts up on a standard 15a household circuit but not on the genny, it’s likely the genny. Off brand generators, specifically inverter generators are known for being hit or miss in their performance at the upper end of their ratings.
By comparison, I had no issue (9 out of 10 times) starting 2 differnet old 13.5k A/Cs with an old Honda 2000. A soft start would have made it a 10 out of 10 relationship! Lol.

AC units (any motor) will need to draw 6X running current for just an instant at startup. When plugged in at home or a campsite that is no problem getting that from the utility.
Problem comes in trying to do it from a generator.
Solution is the Mico air soft start. Don't waste $15 on a "hard start capacitor" those only help when connected to the utility power.

Technically true but for the same reasons a 30amp shore power can handle it, a 3300w generator should be capable also.

Make sure everything else is turned off and the batteries are fully charged before starting the aircon.

Soft starters are typically for trying to get away with 2000w generators.
