HI, I just joined the forum and I know this thread is a little old but this info is great and exactly what I was looking for. I have a new Momentum with factory generator. I'm installing my inverter and want it 3rd in line. My last trailer didn't have a gen and I had the inverter primary with a single ATS. This time around, with 3 power sources,I think I'd like to have it last in line..
Anyway, my question, I also have an EMS to install. My original thought was to install it just before the panel so it would protect from all three sources but my new ATS is Progressive Dynamics with extensive built in protection similar to the EMS, just without the lifetime warranty and readout panel. Now, using your this diagram as an example, I'm thinking to use my new ATS in place of the factory one, moving the factory one to the shore/inverter slot and installing the EMS on the shore power cord only. This way, the EMS would be the first to blow if there was a shore power problem and the warranty would take of it and the ProDyn ATS would protect from a less likely problem with the gen. The only thing that wouldn't be protected is the factory switch on the inverter leg, which I'm not to worried about because it's a quality inverter and the switch is factory low quality that I would mind replacing of I had to..
Am I missing something? Anyone have any other thoughts?
Thank you!!!!
