Thanks again.....Brent

That seems like a reasonable choice. Even with a higher output inverter, running AC isn't practical due to limited battery capacity.

Other than that, the only reasons to consider higher inverter wattage might be to run things in parallel or if you occasionally wanted to use something like a toaster, microwave, electric coffee pot, etc...

For example, our microwave draws about 130A DC, so ~1500W.

In any case, keeping the DC wiring to the batteries as short as practical will help. We used 4/0 copper for a 2000 watt inverter, so you may be able to use 2/0 wire possibly.

Oregon Joe,

That is exactly what I wanted to be able to run.....especially the coffee maker. Maybe I do need to bite the bullet and pick up the 2000W unit. That way i could run anything I would like to within reason, especially with that large battery bank. I'm away from home now, so I can't see the wattage of particular devices.

I just finished upgrading the electrical on our new 24RKS. I put 540 watts solar (3x180 Solar Cynergy $120 each on ebay), Victron 50 amp MPPT Bluetooth charger, Victron BMV712 Bluetooth monitor, Xantrex 2000 watt inverter, and 2 Lifeline AGM 8D batteries. Seems to work great. I disconnected the converter in the WFCO. No need for that, plus you want to be sure that you don't end up doing something like battery -> inverter -> converter -> battery. DAMHIK. AGM batteries, BMV712, and inverter are installed in front storage area. 12 gauge extension cord runs under camper (inside flex conduit) over to WFCO. 30 amp auto transfer switch behind WFCO. Charge controller in cabinet above bed. The only thing that I struggled with was that the Zamp wires are reversed coming down from the roof. I also had a little problem getting the app to communicate with both the charge controller and the monitor. A phone reboot solved it. I've had the Xantrex inverter for several years and it works quite well. No issues running the microwave or the coffee maker, just don't try both at the same time or it will shut down.

Sounds like you put in quite the setup! Thanks for the details, I wan to check these out and see which way is best for my needs.

LeisurePursuits, that's a lovely system.

What do you think of the BMV712 monitor? Have been wanting one but want to replace my batteries with indoor versions (AGM or LiFePO4) first, as the BMV712 has what looks to be an exposed circuit board integral to the shunt. And my battery box on the tongue is not waterproof.

I really like the BMV712. I mounted mine to the frame inside the coroplast accessible through the opening to the power junction. I also moved the frame ground to there.

Very good idea.

Many thanks.

It turns out that the issue was that the seal inside the hub was not pressed in right. It failed and a lot of bearing grease was coating the brake assembly. All four wheels. I had a repair shop fix it now I just need to file a claim with Dexter.
