[RE-wrenches] Voltage seeking transfer switch

[Kienan Maxfield]

I’ve used the Cumins, and it works well. It has a 120 VAC to 12 VDC converter inside, so it doesn’t require a generator battery. That being said, the power supply comes pre-wired to the grid side, so I had to rewire it to the “gen” (solar) side since that side always has power.

Hello, the generator transfer switches work as you request, however the ones that I have used require the generator start battery 12-volt connection to pull the transfer switch.   You may have to provide a 12-volt source to accomplish this transfer.  The last ones I used were from Eaton, Generac, and others, all using a 12-volt to activate the transfer

Hello Wrenches,

Does anyone have experience with a 200A outdoor transfer switch that will automatically seek voltage?  Meaning that if priority voltage source (grid) isn't available and second source is available it will switch to it with no external communication?  We are trying to do a whole house backup, and critical load panel isn't possible.  This may be common, I just haven't done it.

Thanks in advance
