Review on JHBOX Solar Panel Connectors: Male and Female Kit for Heavy-Duty Design (10) – IP67 Waterproof and Resistant to Extreme Temperatures by Joe Patterson

I bought these to make some modifications to my off-grid solar panel in the garage. I'm adding new panels and moving them from the floor mount to the roof so I had to make some connections and new connectors. They arrived with all the necessary parts. They accept 10 AWG wire and are easily crimped. The rubber grommets in the cap were a bit stiff to get through the insulation but it might just have been the wire I used. The plastic for the connectors is tough and pretty much the same as my Renogy panels so I expect it to last a long time. Generally they are of good value.
