Not sure what is going on as I've had my system in my RV for 6 months now (controller with two 150w panels on the roof). Am on my way to Alaska now and all of a sudden the PV light continues for fast blink telling me it's in over voltage. Had no idea what that means. The battery light will stay solid and I can not use my 1000w inverter to do anything like this. I need to say it has been cloudy and rainy for days with little sun.
Once I noticed both PV and battery lights were fast blinking.
Can someone explain to me what over voltage is and means as I don't want to do harm.
Thanks,
Patsy

you solar system should have no impact on an inverter connected to the battery.
Over-voltage - that exceeds specs
"PV is over-voltage Use a multi-meter to check the voltage of the panels. Ensure
that they meet the specification of the controller to not
exceed 25 VDC."
I'd disconnect the panels then the battery from the controller, wait a minute and reconnect, hopefully that will reset everything.
Or the controller is just broke.

Rabird, hate to admit it but I am quite the novice at all this. The blinking on the PV side has gone on for 4 days now but the battery side seems to be fine (either solid and slow blinking for in float). Now that the sun is shinning can use the system as usual just the blinking light confuses me and I don't want to harm anything.
Had the controller for a little over a year now. Am driving to a campground and will be there for a few days... will try pull out my battery tray and see if I am brave enough to disconnent the cables then reconnect to see if it will reset.
Thank you for your reply. Will let you know what happens. If it is the controller gone bad -- what type/model controller would be suggest that would also show me more than just the 3 lights (Wanderer)?
Again.... thanks!

Hi patsy, you are not the first to report the pv over voltage blinking, while the spec is 25v I don't see that ever exceed with '12v' panel or 12v panels in parallel. You can disconnect at the controller in leiu of at the battery, I assume you have access, disconnect one panel wire first, then one battery wire. Wait a short while and reconnect the battery and then the panel. The controller is a good place to measure voltage of both the panels and battery. What you are after is the batt voltage rising to mid 14v, staying there for 2 hrs and then holding FLOAT voltage of 13.?v, That's what I consider a FULL batt, getting to 14+v and staying there for 2 hrs or so. I once loved the View Star but now I'm using a grape solar 40A with bluetooth, I enjoy monitoring the status via a smart phone. Renogy carries the View Star, it is programable the grape needs to picked up at home depot www.homedepot.com/p/Grape-Solar-40-Amp-PWM-Solar-Charge-Controller-with-Bluetooth-GS-PWM-40BT/207100856grape support will email the app. |

I lookd up the Grape controller and like the information. My plan is to be home in a few months and will order on then have someone switch out the Wanderer to the Grape.... I like the smartphone deal. Thanks for suggestions.
The current controller is located on the wall in the bedroom part of the RV with the cables going inside from the bottom. Whole thing is screwed to the wall so unless I take it off the wall don't think I can take the cables out.
Right now, the PV is fast blinking and battery lights states in-float and I am making a pot of coffee so it's working (even on a cloudy Alaska day).
Thanks for jumping in..... makes me feel better!

Does anyone have a video of what "fast blink" looks like, as opposed to "slow?"

If I could upload a video here I would be happy to show you what the "fast blink" looks like -- mine has been going non-stop for 2 weeks now. Personally, I think it's a defective controller and the batteries will go to a slow blink (in float) during the day and the PV still has the fast blink going.
