I have 2 100Ah batteries right now and 200w of solar. Just trying it out to see how it works for us before I spend 10k+. The inverter was reviewed well and only $500

I think you need to step back and layout a full system...a couple 100Ah batteries will be an issue unless you limit the inverter to a small fraction of it's capability.

Ya I agree, but again, I started at 3500 watt so I don't have to buy another down the road (who knows, maybe I still will).

This is the one I got, its pure.

One downside to larger inverters is higher parasitic current. Parasitic current is the current the inverter draws when it's sitting idle with no load. Most 2000w (high-frequency) inverters typically have parasitic current in the 1-2a range. Odd are this 3500w you ordered will be in the 2-4a range. In 24 hours, 4a can discharge two, paralleled, 100ah 12v batteries (200ah total) down to ~50% (lead cell batteries would need recharging at this point); 2a would discharge down to ~75%. FYI, this draw-down occurs with the inverter just sitting in your camper, turned on, but with no load. In addition, your camper probably has its own parasitic current (typically around 1a) to add to the mix, too. It all adds up.

As mentioned, you're going to need a lot more than two 100ah batteries to power a 3500w inverter under more than a 50-60% load. A good quality, properly wired/powered, 2000w high-frequency inverter will power a Micro-Air equipped, reasonably efficient 13.5k a/c, microwave, hair-dryer, etc. Unless you have a need to power two of these devices at the same time, a 2000w inverter will suffice.
