The Jeepster can sit a few months without being driven.I dont want my expensive battery going dead in that time.So I did this....

Photos hosted offsite on Imgur.
------------------------------
My 10 watt solar panel to keep jeep charged up when I dont drive for a month or two. Still have to wire it,hard part was getting it mounted.



Here is my parts list

https://www.ebay.com/itm/PILOT-3-SPADE-12V-BATTERY-MOUNT-TERMINAL-QUICK-CONNECT-CONNECTORS-TOP-POST/112475593564?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

4 dollars to connect wires to battery


The solar panel-metal frame not a cheap plastic one...26.56

Got some solar panel work done.Im wired from battery to controller (had to remove battery and tray)...then broke battery cable end clamp and put on one of those crummy terminal ends,thru firewall,up passenger side of windshield and to top of windshield.Just need to run horizontal about 2.5 feet to left and hot glue that down and wire panel to the charge controller.There is a sill between roof and windshield where this action is taking place.

Have to mount controller and just screw on 4 wires,2 from panel,2 from battery.Paid a whopping 8 dollars from china,got the 10 amp.. 😋 LOL,LOVE the Chinglish below pic 😃

Checked it before final install,lucky I did,positive pigtail was bad.Fixed that,have to remount wiring,....whatever. 😋

Very cool to see it working....Now if I dont drive it for a week, a month, or a year,it will fire up with a fully charged battery.

This is 6 AM. 12.4 volts and 3 of 5 bars on battery charge level.This is almost a 1000 amp/hr AGM battery.Its been run dead 3 times.

It wont take the 6 amps the mains charger wants to give it,only the 2 amp setting.So I'll let the charger stay on until I see the volts have picked up,then just leave the solar charger to charge it at 0.8 amps/hour.

I have since replaced this battery that was in Jeep when I started this project,it was dead.Why I want a charger on it all the time,stupid new battery was $175 dollars USD.So I  put in the biggest lead acid Interstate battery that would fit,and lucky me it fits a nice large one.I want them to last a long time.Now its like 12.6 at rest and 13.5 in partial sun and 14.2 in full sun.It starts with authority at all times now no matter how long it sits,super nice!

That jeep solar charger is nice.I can charge phones,walkie talkies,lights at 12 volt via cigarette lighter plug or the 5.3 volt usb plugs on the controller.If we ever get stranded could be a literal life saver.This is just the coolest small power station ever!One of the best solar projects Ive ever done IMO.

Continues to work flawlessly 18 months later.

Nice!

Can't speak for your rig but 10w isn't USUALLY enough to need a controller. Still, better to be safe than sorry. For years when I was going to sea I carried a 10w? panel in my 98 Dodge Dakota. I'd simply set it on the dash and plug it into the cigar lighter plug. Worked great and kept my battery up, what more could I want?

Thanks Willie! To this day I think its among the coolest solar projects Ive done.Price vrs capability,hits it on all accounts.

Cool you also think 10 watts is a sweet spot for this application.I wanted to put a 75 watt up there but wife wasnt going for that,10 is just fine IMO,Ive seen others use 10 watt also.Small but does the job.

You are right ,I probably could have skipped the controller,but for less than 10 dollars,why? But I agree and you are correct,I could have skipped it with little risk.

Here is my thinking on that. 10 bux vrs 175 dollar battery,I couldnt resist,LOL [biggrin] Too bad I had 3 full discharges before I did this and ruined my nice huge AGM.

I get added security for next to nothing. Also it gives me powered USB ports which is just cool,as is seeing the battery voltages,just fun. I have an led 18 inch light I need to mount that will use the USB,old Jeepster doesnt have inside roof lighting. [idea] [thumb]

LOL,I had serious solar on my truck,2 separate systems of 2 panels,each with 2 large solar agm batteries,Im sure Mrs thought the clean ole Jeep would end up looking like this [eek]. But it WAS cool,worked like a champ and had no issues on the road or off.I wanted to build an offgrid homestead and this would have powered all the tools I would have needed.

Unless you are running some pretty heavy loads (radio etc) when the engine is not running, a 75w is way overkill. For simple battery maintenance the 10w should be plenty, however if you get careless and leave the lights on for a week it won't be. It's all a matter of input vs outgo.

Yes,you are right again,I wanted an agm solar battery or 2 in Jeep,but Mrs flat out wasnt going there. [mad] She is right too,the Jeepster is a very light weight vehicle,unlike the truck you can feel 100 plus pounds in the back.10 watts is very awesome though...[smile] Just love this stuff!

I put one of these:

https://www.amazon.com/gp/product/B01HIM6XIK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1

On my Kubota loader. It mainly sits around but handy to have when you need it.

Besides sitting it doesn't charge its battery when it's running, something wrong with charging system.

Been working great.
