Kev and Van-
How many amps does an AC unit draw on average? Thanks, Doug

I’ll be doing a two year update to this thread shortly (a few tweeks but it’s all still working great!

![]() Doug - Between 10 and 13 worst case when compressor is running. With just the fan in between it’s much lower, of course. There is a momentary spike to more than 20 on initial compressor start. However that settles down almost immediately and the micro air easily compensates, preventing an inverter fault. At this point had I to do it again, I probably would’ve just stayed with a soft capacitor upfront. That’s because I so seldom use my generator and providing BOTH ac units when traveling provides a good opportunity to do so. When bonondocking, I do occasionally run the front AC unit off the inverter mid-day, when solar is at its most productive.

I installed a Microair on the middle Atwood and I've been running it pretty much nonstop without issues. I need to put my meter on it to see what the peak came down to, but you can even hear the difference when it's starting up.

Thank you, Amigos!
I was noodling on the idea of a soft start on my front AC unit and running it for an hour or two in the heat of the day from battery and inverter. I'd have to see how well the solar compensates. Seems like @ 13A, that translates to 100 amps DC. I'm guessing solar could make up 40 to 50 amps of that. Then again... it probably just makes sense to run the generator for an hour or two if need be. That only costs $2 in diesel if it burns 1/2 gallon / hour. Back to your regularly scheduled programming.. Van's kick a$$ upgrade channel. Best, Doug

Hi Van,
When I wrote soft start, I meant something like Micro-Air (not capacitor - only) solution. In this case, I think I can better spend my $ on Diesel when I need AC here and there. Doug

The temps and humidity here on the edge of The Dismal Swamp are truly oppressive—so hot and humid I am soaked with sweat sitting here. The house has central AC but I’m in the SP with just ceiling fan on. I know a couple of weeks is what’s needed for my body to adjust, then I will be cool to do a little work outdoors or sit comfortably inside without AC. The body gets in tune with the climate if you give it time. But I’m looking forward to AZ winter, it’s the COLD that I can’tt abide!

Good update guys!
I am tempted to play with the idea of running a front AC unit off solar/alternator/inverter while travelling. But I'm still on a 2000w pure sine wave, live in AZ where one AC just isn't going to cut it. So IF I were to play with this setup it would be with a 24v 3000w inverter but then again, stuck with one AC in Arizona.... On top of all that I've upgraded all 3 AC units to 15,000 BTU units so just doesn't seem to be a logical solution for this old bus. ![]()
