When we originally put together our electrical system we bought Renogy’s 400-Watt Premium Solar Kit, which comes with four 100-watt panels. But we could only fit three of them on our roof, which left us with an extra panel. The plan was to attach our fourth panel to some sort of tilt mount and install a plug-and-play. .
Now that we’ve got our mount, we need a way to plug it into our electrical system. We wired our roof panels in parallel using the Signstek Y-branch cable connector, so we had some open MC4 connectors to plug in to. MC4. .
Things are way cooler inside Gnomie these days since we’ve been parking in the shade a lot more. We now have a use for our fourth solar panel, and we couldn’t be happier with how the. [pdf]
