Will a WFCO WF-5220 Inverter can it run a single ac unit?

[Gbennett]

I'm new to the late model RV inverter scene. I just purchased a 2024 G350 Toy hauler. I just installed 4-125ah lithium batteries. Later this year (Oct 10th) we are traveling to New Mexico and will be boondocking for 6 days the hope is the run the generator at a bare minimum. The G-350 already comes with factory installed 300 watts of solar panels on the roof and a WF-5220 inverter. I understand we cant run all 3 A/C units. But at this time I can't get even 1 a/c unit to turn on only will work when its plug into shore power or generator is running. What I'm I doing wrong?
Thanks in advance,
Greg B

Since it looks like this is your first post I'd like to start by welcoming you to the forum.

The answer to your question is, in theory, the inverter could handle one of your A/C units. Since I don't have your coach, I have no idea how the inverter is wired. So this is the part you'd have to figure out: is the inverter already able to supply power to the A/C (check with GD customer service with your VIN to see if the inverter supplies power to the A/C breaker, I wouldn't expect that it did) or will you have to look at that as a separate issue?

Since you don't mention a Soft Start, I'm assuming you don't have one. You'll probably need one to run the A/C with a 2,000-watt power supply (the inverter).

Just an FYI: A/C is a real power hog. On my rig, one hour of A/C consumes about 125 Ah, about the size of one of your new batteries.

Here's what I do to get A/C on my coach:

Run a cable from the plug on the inverter (my inverter doesn't supply power to the A/C breaker) to the 50 Amp input.
Turn off the converter/charger.
Run the A/C.
When done, disconnect the cable and turn the converter back on
On our coach, we have about 900 watts of solar and 800 Ah of LiFePo4 batteries. Even with that, I'm cautious about how much I run the A/C.

The AC breaker panel has two bus bars. One bus bar received power from the shore connector and powers the Air Conditioner circuit breakers. The other bus bar provides power to/from the inverter (2 breakers labeled 'inverter') and the microwave and misc plugs. When running on inverter, there is no power to the bus bar with the air conditioner CBs. i am dealing with this now and installed a rotary selector switch so i can power 1 AC unit off of the inverter.

Could you say a bit more about how you wired the rotary selector? Do you have any pictures?

Factory installed inverters do not power the a/c units.

Running the generator is your first option. Second option is to do without AC.

Your AC will consume about 1500-1800W when running, so you will eat your batteries up quickly.
