Mixing MC4 Connectors

[Siamac]

Yes, the specs list 10 AWG max wire for the TEMCo MC4 connectors and most MC4 connectors. The solar panels used have 10 AWG wire and MC4 connectors coming from the junction box so use 10 AWG MC4 connectors and wire to interface with with the solar panels. Have 8 AWG 50 foot run of wire that interfaces with the relatively short 10 AWG solar panel wiring via terminal strips. This way most of the wiring is 8 AWG between the solar panels and the solar charge controllers.

How did you connect the 10 AWG with the 8 AWG?

How did you connect the 10 AWG with the 8 AWG?

Used Dinkel Assembly Kit installed inside detached garage (where solar panels are on roof) to interface the 10 AWG wire to 8 AWG wire.
