The 200amp bus bar box I pointed out before that you have on your drawing doesn’t need crimps, it’s a brass assembly where a machine grub screw grabs onto the cables.


I’m going for mersen isolator too.
Drawing looks fine

This is an 8mm lug on a 6mm bolt, it will still work but I know which one I would be using.

EDIT - I've updated the photo to make it more obvious.

Thanks...

The image in the manual was putting me off:

Inside inverter (6mm bolt)

It's like it's recommended an M8 to me even though it's an M6

Hi Colin....

Are you sure the communication cables are correct in your diagram?

In the manual it says wire it like below (what I drew in red):

Hi Richard
Please refer to the manuels on the parallel
The diagram is mainly for parallel the 2 batteries together

Thanks

Was that the greenbrook one AGT?

So that doesn't use any lugs on the cables?

It's a 6 way... Could get away with 1 box with the positive using 3 terminals (2 in 1 out) and negative using 3 terminals (2 in 1 out)? didn't notice it was a 1x6 oooops :oops:

Or need 2 separate boxes for each?

Yep it’s either a flat blade screwdriver or an Allan key to tighten the bolt
