I have:
-skoolie build
-24V system
-4 x 12V 100Ah Amperetime lifepo4 batteries (5000Wh battery capacity)
-6 x 185W 36V 5A panels ~1100W (either 3s2p @ 108V 10A or 2s3p @ 72V 15A)
-gifted 30A 48V to 12V buck converter (with inline fuse)
-also have 40A 24V, but can buy higher 48-12 capacity converter
-now broken 24V Edecoa 3000W inverter. Came with bus (Edecoa brand), cheap, and temp fan (or something) stopped working recently, so I'm going to upgrade and get a new all in one, which was the plan for some time now.

Why not 48V? What are cons of 48V vs 24V besides 24V needing bigger wires and more inefficient? My system is small (1100W + 5000Wh battery capacity), but if 24V vs 48V all in one unit price is the same, why not save $ on wiring and go 48V? Could expand system later on, but will still have plenty as is.
I've decided on a growatt all in one system. Was gonna get 24V but now I'm thinking why not 48V? The only specific thing I had that was 24V specific was inverter and charge controller. I'm replacing both those, so why not 48V? Seems like at 24V, I'm just paying more for wire and I'm replacing all equipment with 48V or 24V all in one, anyways.
4 batteries in series charging issues? Other potential issues?
Buck converter at 30A: I'll never come close to that.
12v loads: 26.5Amps if all on at once
6 gal water heater 12Amps
Water pump 8Amps
Furnace 6.5Amps
Maybe some max air fans I'll install way down road.
Yes, 40A+ buck would be good for extra ceiling and I have a 24V one, but I was given a 48V 30A. I can buy a new one with higher Amp capacity.
Other reason to do 24V vs 48V?
