Zamp Solar ZS8AWPP Plug-N-Play Solar Regulator

I needed this controller to connect my solar ready travel trailer to my Zamp panel. The unit is small, weather proof and easy to use. I mounted it directly to the back of my panel so it's always right were I need it. The instructions that come with it are easy to follow and provide good step by step guidance. There is even a good troubleshooting section to tell you what various light combinations mean. I must have wired it totally wrong on my first try. I had a light combination that wasn't covered by the troubleshooting diagram, leaving me scratching my head. Once I got my wiring and dip switches set properly, it works like a charm (verified input and output w/ multi-meter).

Works great. Had to reverse polarity on line side or load side for some reason of compatibility with with trailer or solar panel. I think it was load side with the batteries. Does the job with my 90 watt stand alone panel.
