Thor Hurricane (or Windsport) Solar Panel add

Hello all, I have a 2018 29M Thor Hurricane (Windsport same unit different name) it says it is prewired for Solar Panels. Has anyone added any? What does prewired actually mean? Is it a plug and play add on? Any help would be greatly appreciated! Love the idea of adding a trickle more power to the batteries for those week long dry camping moments!

Happy trials!

I have a 2019 thior hurricane ...29m .. mine came pre wired with a controller....I put a panel on the roof, plugged it in.... nothing....

the controller has power and shows battery volts,,.. but shows no solar charge..

seems I read here some where that you have to do something to make it work, but can't remember what..

here's what Ive done so far... pulled the controller off the wall,it's a go power model GP PWM-10-SQ...10 amp controller...

there are 4 wires hooked up a + & - from battery, and + &- from solar charger...( 2 orange, and 2 white...both orange hooked to positive... and whites neg....with a test light, on the battery side... shows power.... on the solar side nothing....but,... if you use the ground from the battery side... the orange lights up... and if you use the battey ground.... the neg lights up...???

my first thought is that the solar panel needs to be grounded??? or the controller need to be programmed or something else???

I have the same Controller in my Magnitude SV34. You just need to add the panels and don't need to do anything else.... other than making sure it is configured for the right type of battery. Nothing should be connected to a chassis ground.

I would first check is to make sure you did not mix up the positive and negative connections on the roof. If you did, it will not function properly.

If that is not the issue, I would make sure you are getting voltage from the wires running from the roof to the controller when there is some light available to the panels. If everything is wired properly, the red and blue lights should be lit.

OK folks... got this figured out...obvious , the controller.... 10a... pretty much worthless...I garage keep my rv so to use it as a trickle charger won't work for me...that and you would never get enough benefit with a 100 watt solar panel to do anything..butÖ here's where you can go wrong quick....these controllers only work with 12v solar panels...my 300 watt is 24 volts... so there's the problem...I need a new controller... which I knew as soon as I seen it was 10 amp.. for me... we boon dock or use camp shore power...when boon docking you have all day to recapture the AH you lost threw the night, watching tv and such..the goal is to not run the gen as much..when it's hot out,.. the only way is to run the gen for the ac.... but winter, you run the heater off batterys...we'll see...I might have to add more storage battery to make it work,

You are correct..... you need an MPPT Controller for those voltages.

I have two 160W flexible Renogy panels connected to my GoPower 10A Controller and it is serving me well. I could only install them in parallel and not series for that reason. When / if my GoPower controller dies, I will probably go to a 30A Renogy PWM or MPPT Controller. Leaning towards the PWM because the MPPT Controller is so big and bulky.

solar charging

I have a similar problem on my 23a 2013 model year, the trickle charge solar panel for the house battery when stored it is not working . I am getting voltage (I installed a meter to check but still not working ) seems diagram of the system is not available or a big secret.Original panel was trashed so I replaced it with a similar panel to re charge the house battery when stored.
Any one hhave a helpful suggestion???
Thanks

Solar charging

I had the same issue with my 2017 26B. I had installed 5 165 watt solar panels , with a 3000 watt pure sine inverter and added 2 more batteries to the battery bank for a total of 4 (later upgraded all batteries to AGM) and had to upgrade the controller as well. Now everything works great and I can power a small city.

Duh, of course! The panel I installed is a 190W 24V panel so the 10A 12V controller can't handle it ... Thanks for making me realize my mistake!

Going to update the controller to MPPT 20A and that should solve my problems.
