Wire connections

[Revid]

I have to tie four 12v panels 2s2p to give me 24v system. Was told I need to go to 8 awg after the “Y” connection but wires on panels are 10 awg ! How can I go to 8 awg?

Are you familiar with 'split bolt wire connectors'?


Or these?

make sure that all exposed bare wire is coated with 'No-Ox' BEFORE you fit the clamp on. Every piece of metal needs to have No-Ox on it before they get mashed together.

Yeah iam familiar with them and thought of them but they would be exposed to elements. Was just thinking there must be a better option. Thanks for the input.

If you think it through well enough. You could place each splice inside a section of 2" PVC pipe shot full of silicon sealant from both ends.

It makes inspection 10 years later difficult, but if your primary concern is about being exposed, ...

2s2p needing 8 AWG is unusual for amperage, but possible for voltage loss.

I was told by Victron tech that it could use 10 awg wire so it’s good to use the mc4 connectors I have.
