Battery Cable Lug Sizes? EG4 6000XP and EG4 LiFePo4 System

Hey all,

I just ordered the EG4 6000XP and noticed that unlike a lot of the other inverters they offer, there wouldn't be any battery cables coming. I looked in the manual to see what the needed gauge would be and am seeing 1AWG for Inverter-to-Battery. So I go to search for my favorite cables - WindyNation - and they offer 3/8th or 5/16ths lug sizes. I've got a 3 battery array with the 3-size EG4 rack and would connect to the EG4 6000XP, so I'm probably going to get 5 feet to connect to the bottom of the array on one side, and the top of the array on the other side.

My question is what is the recommended lug size to get for this? I didn't see in the manual, what recommended lug size, but they did list the terminal block size. I'd rather buy from WindyNation and get an appropriate lug size than try and crimp my own, but would need to know the size.

3/8ths or 5/16ths?

Advice much appreciated!
 
After looking at Signature Solar's site's inverter cables for sale, they're all listed as 3/8ths so I bought the WindyNation 3/8ths one. It's less than half the price of the SS site inverter cables - will see how the WindyNation ones compare to the inverter cables that came with my EG4 3000 inverters. If they're not great quality (should be, never had any WindyNation that had any issues for me), then may look into getting the ones listed on SS site.

Go with 1/4 or 5/16

3/8 is almost to big.

The battery terminal studs on the EG4 6000XP that I received from Signature Solar on Feb 28, 2024 are 5/16 inch in diameter or M8 in metric.
