Battery wiring to inverter

SD_DRACULA

Just wondering how people wired they batteries to their inverters.

I went with this setup so was wondering if it looks good (has been in operation for 1 year)

Using the fuse holder as a disconnect switch and the batteries also have their on/off switches.

I see some people keep adding extra switches/fuses etc but maybe that's for the DIY batteries etc.

Also what lug crimpers are people using? Need to redo some cabling with 35mm cables.

Your setup is the same as mine, and seems to follow the best practice as far as I can see

Yeah that's what I thought.

What crimpers did people use from amazon?

Reviews are hit and miss for both but I only need it to crimp 6 lugs so I should hope either are fine.

I have the hydraulic ones they work fine

Which way are you guys reading the following diagram?

I am reading it that you have to double up on the + and - cables if going for 200a charge/discharge (diagram on the right)?

Not sure that makes sense to me since 35mm2 should be plenty for 200a across one - and one + cable and I don't see that in any of the Dyness manuals (unless that's so you don't heat up just the one pair of cables and spread the load?)
