When sizing wire between batteries, fuses, inverter, bus bar, breaker box/fuses, etc.
My set up:
Panels: 1100W panels (6 x 185W)
CC: 60A
Battery system: 24V, 4800Wh, 12V x 4 @ 100Ah each, LiFePo4, 2s2p
Inverter: 3000W 24V
When is the wire too big?
When does upsizing become pointless...
Inverter fan keeps running constantly. Just started doing this yesterday. Zero loads being pulled thru inverter. Wired-in remote installed on wall panel doesn't turn it off anymore like before. It doesn't respond at all. When I turn remote on/off, inverter fan slows slightly upon power on, and...
I've got:
-Eg4-3000EHV-48 all in one
-4800Wh battery storage (4 x 12V @ 100Ah lithium from LiTime)
-1100W solar: 6 x 185W, going all series for ~ 220V PV input
-Victron lynx distributor
-Victron BMV-712 smart shunt
I'm going up to 48V system @ 100Ah with 4 x lithium batteries in series...
I have 4 x 12V 100Ah LiFePo4 batteries. Wired in series for 24V 200Ah. Batteries have 100A/1C discharge rate (LiTime brand).
So my breaker/shut off switch should be DC rated at 250A or 225A correct? 200 x 1.25 to allow for safety margin puts me around 250A, but 225A might be better due to lower...
Looking to potentially buy EG4 3000 EHV-48 all in one.
Does fan run constantly? Even with no loads? I've heard the fan runs constantly vs only on when it heats up from loads and needs to cool down. Anyone confirm this?
How loud are inverter and charge controller fans? It will be in skoolie...
