Hi,

Can someone point me to where to find parts for these connections, I've just bought longer 10 AWG cables to move batteries a bit further away from the inverter, I already have the spare plugs, it's just the metal inserts I need to crimp, do I just need a standard part with the correct diameter to fit the inverter/BMS connections?

I read from this post that I shouldn't exceed 3m long, which is fine, and to use 8 AWG? I was following:

Sadly these connectors are not standard MC4 as they have a groove in them, but the good news is FoxESS supply a spare set with each inverter - double check the bag that came with the inverter.

I've never been able to source them myself but if you don't have the spare set contact you're original installer as they should have lots spare, failing that it'll have to be an email to FoxESS support.

I see, that relates to the "pin contact" too, I have the plastic plugs. Thanks
