DIY inverter transfer switch questions

[beemerphile1]

Back story, I installed a Xantrex PSW inverter in my previous trailer and was able to modify the circuits in order to get everything onto one circuit and operate from the inverter. I used the Xantrex PROwatt Auto Transfer Switch. We occasionally had an issue with the contacts in the PROwatt sticking and I think it was because we pushed hard against the 15a rating.

I have moved the inverter to our new TT but have two circuits I want to power from the inverter.

Option one is adding a second Xantrex PROwatt, but one of the circuits is 20a. I fear the contacts sticking will get to be a problem, the PROwatt is not available in 20a.

Option two is a DPDT (double pole double throw) manual switch. The manual switch would certainly keep it simple but the wife likes everything automatic.

Option three would be some other transfer switch but I don't know where to start on that one.

I'm open for suggestions on manual switches, automatic transfer switch or maybe something else that I have yet to consider.

Get your own plastic box. (2) would offer 60 amp transfer capacity. One for line the second for neutral. Real-world experience not a hypothesis

Progressive Dynamics 30 amp automatic transfer switch is what I installed.

Hi,

20 on 20 = some arcing

20 on 60 = not as much arcing.

Path:

inverter-->transfer switch-->subpanel-->items to be powered.

It doesn't get much simpler than that.

Personally I do not use a transfer switch. I manually set the fridge to propane, and the default for the converter is unplugged.

Go Power makes a 30 amp transfer switch. I'd try to find a 60 amp one.

After my original post I found the KISAE Technology TS20A 20 Amp Transfer Switch. I'm thinking two of them, one for each circuit would keep it simple. Reasonably priced at $65 each from Don Rowe and it would keep everything automatic which pleases the wife.

We love the new trailer but it has been a lot of work making mods. I've probably done 100 or more mods in the last couple of months but I love doing it. I modded the previous trailer for 13 years and doing this one in one summer.

I opted to do it manually. I have the Xantrax 2000 PSW. I plug into it with an extension cord and plug that into shore power. Flip off the on board converter circuit breaker switch and viola the fiver is powered up. Takes like a minute to do.
