This worked well to add solar connections to the outside of my caravan. I had to make my own protective covers for the connectors. Because the connectors face down, dirt and spatter can get into the connectors on the trailer, so I grabbed some spare solar connectors, sealed one end with silicone sealant, and used them as caps when my solar panels weren't plugged in. It would be nice to include some weatherproof covers with the panel.
