I’m doing my first job that involves a solar panel so I am a total rooky with a question.
The job has one solar panel with about a 40 volt output. The panel comes with a negative and a positive output wire with some special pre-made connectors. The panel feeds a battery and charger system that goes on to feed a heliport lighting system. The solar panel, battery/charger and lighting controller are all mounted within a few feet of each other on a fence that forms the perimeter of the landing area. Most things seem pretty straight forward except for the wiring between the solar panel and the battery/charger. The solar panel has a positive and a negative wire with each having a special looking connector on the end.
My question is about how to extend these leads to the solar output to the battery/charger. I’m picturing these DC wires being run to a pvc junction box and spliced on to thhn/thhn wire run in pvc conduit back to the battery/charger. I’m not sure how to have the solar output wires enter the pvc box. Can I just drill two holes the size of the insulated wires?
