So I'm trying to put together a parts list for my dad's camper upgrade and one problem is causing other problems... stupid physics!
The biggest issue I have is space. There isn't a lot of open space where I want to put all the guts so I'm limited to a 24v battery base because a 16s physically isn't going to fit unless I use really small, like 50ah, cells. I can fit an 8s build in there with 280's, maybe even a second battery if I mount them just right... maybe...
In a perfect world I'd get one of the 24v 3600w AIO's out there and put it between the 30a RV plug coming in and the 120v input to the converter, basically tricking the camper into thinking it's plugged into shore power all the time.
I don't think I can physically fit that in there though due to the way that end of the trailer is laid out. So, Plan B was to get a 24v base inverter/charger and separate MPPT controller because I can find room for 2 small things a lot easier than 1 large thing.
I'm just striking out on 24v based inverter charges that check the following boxes:
3500-4000w range to duplicate what a 30a shore connection can provide
NOT Midnight
24v battery based
NOT Victron
120v single output (no 240v systems)
NOT Victron
Built in ATS
NOT VICTRON
Less than $1000
So far the only thing I've found is a
SungoldPower 3kw/9kw LF unit for $900. That should be plenty even to fire up the AirCon if needed, but at "up to" 88% efficiency and probably near 60w of standby power, it's a tough pill to swallow. Any other options?
I'll be pairing it with a HQST 60a MPPT controller and probably 1200-1800w of panels (roof space willing) with a 280 or 304ah battery and 150a BMS home build.
Hopefully when I get home and start crawling around with a tape measure I'll find a way to get a 48v 280k build in there, so 48v recommendations woukd be helpful too.
Thanks all!
Oh, and NO VICTRON!!
