Hi ALL,
new on forum, just putting together my system and wondering if I can get some advice on sizing cables from a Sol-Ark 15K to (2) battery racks ( w/(4) EG4 LifePower4 48V on each rack).
I am planning to use (4) 1 AWG DLO(RHH/RHW-2 listed) copper cables from the Sol-Ark 25K inverter to the bus bars at (2) EG4 battery racks (4-batteries each). Cable run is about 18-20ft between inverter and rack bus bars?
The 1 AWG DLO cables I am looking at are rated at Continuous 220A @ 90^C wet/dry per manufacturer, the Sol-Ark 15K has (2) pairs of terminal for battery connection (160A/pair, 275A/2-pairs), running (1) pair to each EG4 battery rack (4 batteries) appears to be sufficient in therory since the max per Sol-ark terminal is 160A per terminal pair. With 1 AWG (220A) cable, there should be a 37.5% amperage capacity overhead, and roughly a 1.0V drop over 20ft, vs 0.5V drop for a 4/0.
The DLO cables are quite pricy, so just want to do what is most effective for my budget. Also, since welding or automotive battery cables are not recognized cable designations by the National Electrical Code which my AHJ uses, I would likely fail my electrical inspection if I go with those.
Wondering if I am missing anything. Any feedback would be greatly appreciated. Thanks.
