I have 3 - 100w Panels. All of them worked (in parallel) with my Wanderer Controller. I got the Rover 40A in today and it only recognizes 1 panel. The PV light comes on. When I connect another panel, the PV light goes out and the Rover shows "Nighttime". It doesn't matter which of the 3 panels, I run, I can only charge using 1 panel. Is there a setting I am missing? Why are you hooking them up one at a time? Or did it start not working when you hooked it up? What kind and how many batteries are you using? What voltage?? More info needed.... I have 3 100AH Lead Acid Batteries. They are connected in parallel and are 12 volts. I bought a beginner kit from Renogy of 3 - 100 watt panels (Mono) and a 30A PWM charge controller. I would hook all 3 panels up to it and the PV light would shine bright. I just bought the Rover MPPT 40A Controller because I wanted better efficiency. I don't have the panels mounted. I take them out of my Motorhome and hook them up 1 at a time. Individually, each panel alone causes the Rover PV light to come on. Add either or both in parallel or series and the PV light goes out (Nighttime mode) I think you need to hook them up all together and then hook them up to the Rover... MPPT is different than a PWM.... I did that early on with my prior 40a CC and it did the same thing... Thanks. I'll try that. I did see a kit on Renogy's site with the same setup. 40A Rover and 3-100W panels. The diagram shows the panels hooked up in Series. Is that how you do it? Yes sir that's how I did it and it worked great... Good luck... Appreciate the help. When I hooked up the 3 panels in Series, the MPPT Rover accepted it. Thanks! Well there you go, Glad I could help... |

Kind of confused, should this CC also be able handle the 3 solar panels in parallel ??
I would say yes !!!

I bought the Renogy 3 panel kit with the 40 amp Rover, waiting on a battery. I was planning on wiring the panels in parallel, I read that if wired in series and one panel was shaded it would decrease efficiency of the other two? Did I base my plan on bad information? What is the difference does it make to the controller? New to me and want to go boondocking with our trailer.

For an MPPT controller the higher voltage should let it maintain the necessary charge voltages with less sun. In series shading on one will kill the full string. Think garden hoses connected together, kink one and the flow stops. |
