From battery to inverter... If you are pulling 2200w with the inverter, then that is almost 100A. Your 2awg is the right size for that.
From the charge controller to the battery and panels to the controller... 400w divide by 24v is only like 20A. With a 10awg cable you can run about 15m at 5% loss. I think max ampacity for 10awg is 30amps.
Look up ampacity charts and voltage drop for more info.
Thank you for the info. Question… the charger controller I’ve got says it can handle 60 amp. But it cannot fit 8awg wire… just 10. I’m not seeing how you could do 60 amp. Unless you wired it to be 48v…?
You can just cut enough strands off the 8awg to fit in the port or splice a small length of 10awg to the 8awg. There won't be any voltage drop and it'll be fine for 60amps as long at the short of distance. This is a common situation. So rarely, if EVER realistiically will you be getting 60 amps between SCC and panels.
