Question Need advice from someone with knowledge on either 30A or 15A power systems

You might consider an inverter for the 15/20 amp outlets and maybe refrigerator and running the large consumption appliances, microwave, water htr, elect. htr., a/c, from ac. If you're planning on a lot of off grid you'd need a lot of battery to keep those bigger appliances operating.

I'm planning to use a beverage cooler (44 can) as my fridge (fridge door type cooler), and that has a 12 volts on the end of it, I think, but I don't remember. I think the A/C unit is the only thing that will use AC power except both of those AC outlets.

I'm actually considering not using the inverter for the outlets since I already bought the power center.

I copied and pasted my earlier reply to Red Baron.'I will have 1 2-outlet inverter to supply 2 AC plugs for up to 500w. I MIGHT also add a single outlet 1500-2000w inverter for a rooftop A/C (ASA AC135/AC150). MIGHT.'

When as you say you "plan to have 2 large special batteries". They'll need to have the capacity to run that rooftop a/c for a time, unless you have a method like the Evotrex to auto replenish energy to the batteries or unless you're planning to plug up to a pedestal.

I have occasionally considered that I could attempt to install a couple solar panels on the roof.

If you're looking to sustain yourself off grid for a time you'd need something substantial. Even Lightship with it's massive solar admits that it's time off grid when running the a/c is reduced considerably.

No, I'm not trying to do that. And I'm on social security. I only make one or two hundred dollars extra every month on top of that so I'm just doing a basic RV build. Lol I'm poor. If you go to my OP of this thread, you will find a link to Matthew's Volvo site. You'll see my entire build and all of my ideas/sketches. I'm about to pick up the required steel for both the tongue and the wall for that build. I have flipped a couple cars for a small profit so that's how I'm able to get this much going already.

Well hang in there.

You do understand that 120V AC is only available when your connected to shore power right? If you need to convert your battery power (DC) to 120V AC then you must have an inverter. The power center will charge your DC from shore and provide for breakers and distribution of both AC and DC power, but does not convert DC to AC. That is what an inverter does.

As a newb, I failed to realize that the air conditioner hooked up to the power center would not be able to provide me with cold air off grid.

On a different note, I have purchased both a genuine WFCO WF-8930/50 and WF-9865. Next up, a 2500 watt inverter.

Before you make a purchase, you will need to know the starting power requirements of your air conditioner as well as the battery and inverter peak and sustained power abilities.

Even with a very large battery system, air units off grid are normally measured in minutes usage ( up to 120 ) vs full day. This information should be researched to the point of understanding before you make your next purchase. So far you have the write power center for a normal usage scenario. The next steps of solar, inverter, and stored energy are expensive, and you may want to know your goals before proceeding.

The screenshots show AC and battery. I downloaded the manual for both a Chicago Electric 92464 and Cobra cpi2500. I also downloaded a spec sheet for that Cobra. The cobra looks cheap though.
