Mine is working correctly as of today.
1- When I took my motorhome out of inside storage for the winter, the chassis battery had died and the house batteries, which were used to jump start the engine, had low voltage.
2- Once home, it took awhile for me to drive the motorhome to charge my house batteries. (My solar hook up to the house batteries was incorrect, and it has always showed 0 voltage to the house batteries.) When I turned on my inverter, it said “fault” with an error code because my house batteries were too low.
3- In all of this, my solar controller was completely off — no lights on.
4- After enough driving to charge my house batteries, the solar controller came to life.
5- Today, I finally figured out how the wiring is supposed to work on the house batteries. When I bought the motorhome last April, Entegra had connected my white solar wire to my aft house battery’s negative terminal — which is correct.
But the black solar wire was connected to my forward house battery’s negative terminal — which is not correct. I moved that wire to the forward battery’s positive terminal today. As soon as I did this, my solar display showed voltage to Battery 1 for the first time ever. I now have charging to my Battery 1 (House) and Battery 2 (Chassis) from solar.
So … 1) Are your house batteries charged completely in order to get your solar controller to come to life? 2) Is your wiring from the solar controller connected properly to your house batteries and to your chassis battery?
If you are not sure, I can give you more information and even include pictures of mine for you to compare if needed.
I’m very excited that I finally have everything working properly for the first time. I hope you can get yours working properly too.
