I need to wire four panels in parallel, the panels come with a 24'' lead and MC4 connectors. I need to add length to the leads to reach the junction box, I can cut the MC4 connectors off and add wire but it voids the panel warranty. Can I buy extensions with a MC4 connection with a open end to wire into a junction box? or what is the best way to do this?
