I took advantage of the current SS promotion and I'm expanding my setup from a single to 3 EG4-LLs, and hence moving from the 4AWG cables that came with the EG4 3000 to a bus bar setup. I need some help with the math part as the transition between 2 very different wire sizes looks odd to me:
Presumably the 3000 should be able to handle (3000/48/0.85=) 73.5A, the manual says max amperage is 80A but then also has this note:
"Please Note: Maximum current drawn by the inverter is 80A. If using EG4 Batteries, the maximum output is 100A."
In addition, the 3000 has terminal blocks for the battery connection which according to the product page on SS accommodate a max cable size of 2AWG, which aligns with the above max draw.
I'd like to future proof the 3-battery cab cabling, in case I upgrade inverters later on, hence would this cabling size configuration work (disregard lack of fuse)?
3K inverter(s) -> 2AWG -> bus bar -> 2/0 -> cab with 3 x EG4-LL 48V
thank you
