Could be a good find, I don't know anything about the cheaper unit. If it has a shunt, which this one does, it has the capability to do what the Victron one does. Just need to dig through the...

As I see it, the issue with running an A/C isn't the inverter. There's video of 'gone with the wynn's' where they test running their A/C and it pulls about 1,100W while running. 1100W @ 12V at 95%...

No problem. The purpose of measuring actual amps in and out of the batteries is to establish an actual State of Charge. IE, if the battery a capacity of 215ah and you draw 43AH the SOC is now 80...

Converter is 24V, indeed the losses are lower at 24V vs 12V. I built the system to ultimately use lithium batteries, possibly salvaged from an EV if I become confident in how to work on and adapt...

Yes, it's just got an extra detail because I've done a 24V system to reduce line losses and voltage drop. I'm running a 24 to 12V stepdown transformer to run the DC side of the trailer.

That was a depiction of a big draw day that would require a generator to get me back charged up. In theory three full hours would nearly do that...I never get three full hours.

Not sure I was clear on that:

your case: 40 AH * 12.8V = 512 WH
my case: 80 AH * 25.6V = 2,048 WH

Full sun solves all the issues, I've lots of panel to deal with that, keep in mind it's a 24V system so 80AH is four times your 40AH.

7 pin wiring - how much juice?

It looks as...
