Reasons to stick with 12v?

What inverter/SCC would you have used if you'd stayed at 12V to keep fan noise down?

If I did it again, I think I'd get one of the "budget" inverters from will's site and pair that with a renogy or rich solar 40 amp MPPT

Hello i had a good run with kings 3000w inverter was able to pull 2kw (did not do it for a extended time) without the fans running
Renorgy 40a mppt is where its at cheap and fully customisable

And here I am, regretting staying with 12v... but I'm also using a MP II 2x that is quiet. Under high loads, the inverter does have a slight buzz, but it's not anything that bothers me. My 5th wheel has a 60a CB for the 12v systems. My leveling jacks are fused at 30a each, and they only extend two at a time. My reason for staying with 12v, as I started with two 12v LFP batteries and didn't want to have to deal with replacing those batteries and did not want to get into wiring batteries in series.

I am off grid full time and use 12 volt fridge/freezer water pump and have many 12 volt appliances I run off direct DC.

So my main system is 12 volt using a 400Ah Enjoybot LFP and 12 volt inverter.

That reduces the extra wiring for parallel or serial connections and I can get cheap 12 volt inverters locally if needed.

I left my 12v system intact. Then added a Samlex EVO4248 with a 48v 302ah battery for my ac loads. Mainly because of my wifes bypap. However as many times as I have been unable to find a campground to stay in it is also there so we can boondock and still have coffee in the am.

All the replies are very helpful. Im starting to lean towards keeping the existing 12v setup and then add a 24v battery and inverter. With winter coming its easy to rely on propane. Its the summer when i wish i had a mini split and enough solar and battery to run it.
