You should nail down that bank size, a 400AH LFP bank @ 0.4C is 160A, 160A * 12V = 1920W, you could run this through a Honda EU2200 Companion w/30A plug and a 20A circuit on the charger, but that genset is gonna be wound up to 100% load, so you can kiss quietness goodbye..
I don't want to build a system that's running on the ragged edge- I'd rather charge slower and/or downsize the house bank if I need to.
But by your math, I should be able to do the 120A charger off an EU2200i. Do I need the "companion" model to gain the 30A connection, or can I do that off of a regular EU2200i?
...you do know you can chain Honda EU chargers in parallel if you need more wattage but needa keep a small easy to carry genset.. two together can give yeh 4400W max and each one would be running at half throttle and likely much less decibels...
Yeah, but I barely have room for one of them, and the Rube Goldberg factor of running two generators would turn me off.
If your charger maxes out at no more than 0.4C, and can handle continuous duty operation then it would be fine, make sure whatever you get states it works with lithium.. one designed for Lead charging is gonna only expect to output full power for a short time and not hours on end.
Yeah, I'm looking at fan-cooled components, and they say they are designed to work with lithium (although the online operators manual is not real helpful there).
No 24V alternative winches?
Not that I can find. These winches are all going to be working well below their capacity- the smallest winches I could find with automatic load-holding brakes, were rated at 3,500 pounds each.
What size Inverter you planning on running?
The 9K BTU mini-split is rated at about 700 watts, but lists a range that goes up to about 1,250 watts. Here are the specs:
I figured a 2,000-watt fan-cooled pure sine wave inverter would be good.
Is your alternator output 12v? I'd of thought those big ass military trucks would be 24v already like most ambulances and stuff with high power needs.. If you double your voltage you cut your amps in half, so things like fuses/cabling and everything goes down..
It is 24V.
For smaller 12v loads you can easily convert 24v to 12v with negligible losses with things like these:

Yeah, but those winches aren't exactly small loads, even though their use is going to be pretty intermittent.
Most RV style fridges and appliances are actually dual voltage 12/24v if you check their spec sheets.. if my LFP bank was any larger than it is I'd probably go 24v, its not that restrictive..
My wife is looking at the Norcold #N3104 3.7 cubic foot unit. 16.2A @ 12VDC, or 1.8A @ 120VAC. We do not plan to use propane to power it.
And I'm listening...
