Looking for a transfer switch

Hello,

Does anyone know of a 120v min 50amp transfer switch that also switches the neutral. The solar set up I use on my work truck has an inverter that detects ground faults through the neutral, so the typical transfer switch causes the inverter to fault out when switched from generator to inverter power. I've been shopping around and can't find one as of now. The current switch I use is 240 volt 100 amp and I tried to switch neutral on the other side of the bus but for some reason, it won't work correctly.
Thanks in advanced.

Eaton catalog number DT362UGK is a 60 Amp 3 pole double throw safety switch. You can order through an electrical distributor like Rexel.

Here is the Eaton brochure for double throw safety switches. If you need circuit breakers for any reason look at the Generac transfer switches used for generator hook ups. You can buy both of these on Amazon.
Yeah needs breakers for sure. I could use the double throw to feed a panel but space is a concern. I have a 240v transfer switch already with phase on one leg and neutral on the other, for reason the inverter works and the gen doesn't, double checked the config multiple times, unless.. the breaker tieing the generator neutral in is bad but I get continuity on the bus, idk what the deal is.

It seems to me that your set up should work since you are switching both the hot and neutral wires. Do you have the ground wire connected to both the inverter and the generator? Also check that the neutral of the generator is not connected to the generator ground. I would spend $20 and buy a new breaker and see how it works. If it doesn't work with the new breaker I am not sure what else you might check.

So where is the earth connected? If you are running off the generator, then the neutral and earth should be connected. And they should be connected to the chassis of the vehicle. Then live and neutral should go through an RCCB.
