I have a 2015 Outback with no built in solar. I use two 50W external Renogy panels via a Renogy controller and connect to my two 100A AGM batteries. I monitor via a Victron Smart battery monitor. I have questions.
One: is there a better way to connect the panels to the controller. I have a Renogy 20' 10AGW sized braided wire to extend out to my solar panels. It seems impossible to fit the size 10 braided wire into the small square connection of the controller. I've used pliers to try to squeeze the wire into a small enough shape to fit into the connector, but the connection always seems tenuous to me, and sometimes fall out as it is moved around. Is there some sort of connector that can be more securely attached to the wire that will slide into the connector, which I can then tighten securely.
Second question: Renogy calls for the battery to be connected first, and then the controller connected. My renogy controller attaches to the battery via alligator clips, and the rest of the wiring is permanently wired to the controller and then to the solar panels. So any time I connect to the battery, the solar panels are already connected first. The only way I can see to get around this is to unscrew the connectors to the panels each time I want to connect us.. That seems unwieldy. Thanks for any suggestions.
Third question: I saw this deal for a 200W system, panels, controller, bluetooth module on Amazon for $260. Any thoughts or feedback about this system?
