OK, so I'm getting close to getting back up to camp to start working on the solar setup cleanup & expansion. Time to check my work please. There are some parts I already have that I'm going to be using, they'll be notated in the parts list.
Parts list:
Battery: 304Ah 24v
8s 304Ah Eve cells (have 4 in box already, buying 4 more soon, c'mon Amy!)
JK B2A8S20P-H with the heater function (already have)
4x 24v 15w heating pads
80a 2-pole breaker (can't find a 150a to use on the battery so I figured 2x wires in and 2x wires out, will that work?)
Isolating box penetrations
3x Noctua 120mm IP rated 12v fans
Digital thermostat for fans (to cool the box down in summer)
8u rackmount case (I'll have to find one at the local used PC shop, but
I have saws, drills, and a welder to make my own case!
Inverter Side 24v & 120v
Growatt 3Kw 24v AIO (I already have)
150a Breaker/Disconnect for 48v
40a 2-pole breaker for PV input in a DIN breaker box
Small project box with a momentary contact switch and 10w/50Ohm resistor (already have all those parts)
2AWG copper cable and 3/8" lugs (I think I have the lugs)
4-port Combiner Box ~102v @ 34a total (already have, will mount at the panels)
12x 208w panels in 3s4p (already have on site)
8AWG wire from combiner to AIO
Ground mount array of PT lumber
Lots of conduit
12v System
4x WallyWorld DC29 110Ah FLA batteries (already on site)
Weize 40a MPPT (already on site)
2x 208w panels in series (already on site)
4-lug bus bars (already on site)
150a MEGA Fuses (already on site)
4awg copper wire with 5/16 lugs
12-port DC fuse block
Utility 12awg wire
50a 2-pole breaker for MPPT to bus bars in a breaker box
8awg wire and lugs
Battery Disconnect to fuse panel (already on site)
Notes:
The battery box will be surrounded by 2" thick Mylar coated foam and will have 3x 120mm fans through the battery box to suck air through in summer.
I think I need to replace the 60a breaker in the combiner box with a 40a, yes?
Yes, the MEGA fuses are oversized but 1) I have them and 2) worst case I can still get all my loads off a single battery.
It started life as a travel trailer so I have a lot of 12v systems. I have a 60a step-down converter but I think I like the idea of keeping everything as a separate system for redundancy.
No, I'm not buying Victron.
OK y'all, how am I screwing myself over?
