The NPS 4500 and 5500 generators don't list any sound level specs, that I can find.

I am not doubting you, but something does not seem right with that, especially if it is a "standard" built in converter.

What unit is it? Most have some form of multi stage charging, and that does not happen with 3 amps.

The Noco will be a huge upgrade over the existing charger, the soft start will allow me to run both AC units on the generator or 30 amps shore power and the AGS to make it happen with minimal intervention.

Which AGS are you looking at?

Thus far I have never had a real situation when both ACs were needed where I only had 30 amp shore power. At home I have played with it and sometimes both run and sometimes it shuts down I quit trying because it sounded kind of weird.

Oddly our experience is we either have 50 amp service or only 15/20 service where we are confined to 1 AC regardless. I am sure it will happen eventually to be at pole with 30 amp and no 50 amp? But hey any excuse to run generator is to me what it is all about. Never had situation where at night it was so hot that I needed both ACs anyway.

Speaking of hot, we just survived that crazy freeze here in Dallas. I pulled out my portable inverter and it ran 3 straight days non stop. I have a transfer switch at home so we had all the essentials in the house with no extension cords. Because power would only stay on 30 min to an hour before shutting off again I just kept the generator running so I didn't have to fool with flipping circuit breakers and restarting genset. I had to refuel ever 6 1/2 hours (1.8 gal of gas). It was by far the best workout that generator has had since I bough new 10 years ago. Our home stayed warm and it has paid for itself (again). I started the RV up twice during the freeze and engine and Onan 5500 (67db) started up with no issues and no priming.

It looks like you are right. I did some research on it and there are a lot of negative reviews on that unit. Search "model 6345 power converter charging" and there are a lot of results.

It so yes, 10 amps/battery is a lot more. Just keep in mind that you will need about 1hr of charging for every 10% of battery usage in the system you proposed. That is not to say it is good or bad.

I have heard nothing but good from Magnum. It was in the coach standard I was looking to buy originally. The coach we bought (Winnebago 29VE) was perfect but no AGS, the model above it Adventurer) came with the Onan EC-30 AGS standard but the coach was $25k more and it was only relevant difference to us.

I got with Cummins directly and had Winnebago dealer install the below the way it was installed in the Adventurer, but I went a step further. I had then wire the shore sense wire in front of the ATS. So with my unit when I am driving and the ACs are on, when I get to the campsite gensets continues to run. When I finally get to connecting shorepower it will automatically shut the genset down

Similarly, if I am at a campsite and power is loss, my EC-30 will automatically start regardless. It cost a little more than I had hoped (*Dealer labor) but I just love it. Onan extended the warranty from 1 year to 3 year to align with my generator which was a nice touch.
