I use a 10w solar panel and PR1210L regulator [cost approx $80-100). I made up a small plug at the back up under the number plate and run a wire to the battery.

I don't disconnect my battery or do anything like that. The solar panel is mounted on the carport roof and the wires for it come down the column and exit just about adjacent the the rear of the car.

So simply drive in and plug in. Its a '98 and the battery is in the boot but you could make it work for any position.

Not quite on topic, but sort of relevant.

awesome setup, I think I'll copy it for the ute that lives outside.

those cheapy solar chargers do not work well with good quality (eg AGM) batteries because they don't regulate properly, so while the $80 seems expensive it is actually pretty cheap for that sort of setup

I probably should add that I have an Odyssey battery in mine. But the solar changer set up should work with any sort of battery..........but pls don't forget your solar panel regulator otherwise you will cook the battery cos on a warm summers day they can run as 20 volts and the reg. keeps this to 12-14 volts.

Then wire and either alligator clips or a plug for your battery end.

As an aside I use this same setup on my minidumper and excavator as well. They can be parked out in the paddock for days at a time and in the cold weather that is death to batteries - but with this setup, I turn the key and they go, always charged and ready.

Let me know how you go. If you need any help or more info let me know in msg's and I should answer quicker - cos I get an email notification.

Terry that setup has to be for a second battery and fridge, its way overkill for just the battery alone. You'd need a very good regulator for that one as well cos on a hot day it would be thumping some amps. I'd also check that it doesn't discharge overnight, a lot of the bigger solar panels don't include the blocking doide so what you make during the day gets lost at night or in dark sheds/carparks etc. Just check your voltage after a sunny day and then again in the morning, if its dropped away heaps it means one of two things your battery is cactus or the solar panel setup is discharging. To check that disconnect your battery after a sunny day and again check the voltage if its down heaps its the battery, if its not then its the solar panel set up. A blocking diode costs around $5 at a guess and is an easy fit for just about anyone but needs to be orientated correctly.

And by dropping away overnight, I'm talking from 13 volts down to say 8 volts. Discharge is pretty severe when it happens - thats for your size panel.If the panel is smaller and discharging the rate may be a bit smaller say down to 9-10 volts.

awesome thank you will definitely be trying this for my self

I really appreciate the time and effort you've spent on my system. Having been installed by Pat Callinan I'd be interested in what ARB has to convey to me about this Redarc Management System wrt how the regulator operates etc.

I only have a bit of knowledge about chemistry but bugger all about electricity.

Oh I should have looked a bit harder the regulator is there next to the battery. Being a good one plus the set up being installed by ppl that know what they are doing I'd say your fine. But its for a fridge or some such for sure, you could put a good quality inverter on that and use power tools as well - either directly or to charge 18v batteries via the 240v charger. We do that with some of our work vehicles.

Anyway having that sort of system is a definiate bonus, you could go 4wding and trekking across the centre with that set up.

I've ended up using the Jaycar charger on a digital timer i bought from Bunnings.

Turns on every 2nd day for 45 mins. Has been going good now from when i started this post.

P.S i have an Optima battery too

Which trickle charger does everyone use? I'm going on holidays in the future, and last time it was left for a couple weeks off twice per time, and don't want to keep doing it to damage my battery so looking to have something hooked up to the battery which connected to the car, as I need to keep my immobiliser system on. If the battery goes flat it will mess up my security system (already happened once)

I was looking at the following, so can have someone turn it on every couple of days and run it overnight then turn it off)

though these don't say anything about trickle charging, don't want it to overcharge the battery.

I have a projecta one.  A proper trickle charger can be left attached 24x7, that's what the trickle bit is about.

Yup, just wanted to make sure I found one that was a trickle charger and not just a battery charger, not sure if there is a difference there but assumed there was, was why I was worried about overcharging.

    • Probably being in IT for 2 decades, and spending my time documenting trees worth of shit and also being on the receiving end has taught me a thing or two.
    • Why's that depressing, wouldn't it be able to go indefinitely until the battery gets old and craps itself? If it's constantly on charge/maintaining charge, won't that keep the battery healthy?
    • One of my concerns initially was if something catches fire somehow.
    • I think I know what you mean. I saw the same thing a while back, I think either the images on the website were wrong or the model was slightly updated. It was weird when I first looked at it, same model but different looking unit.
    • At work we've got a smaller version of the Projecta that Duncan posted above. At home, I have an ALDI trickle charger. Ive had it for about 8 years now. Only issue with it, it's a smart charger, so if the battery is dead, it won't bring it up, but I have a variable power supply that I limit current on, and set to a max of 14.4v. once it starts charging up, I put the aldi unit on and remove the variable PSU. ALDI one will do 12v, or 6v, then has mode for "car" "motorbike", and "snow". With car or motorbike more for its internal workings, and snow is the trickle mode. I have a battery in the garage that lives on this charger for about the last 18 months now on Snow mode. When I need to charge my other batteries (eg, ones that have died in a car), I get them started and then run it on car mode. Voltage is always sitting really nice, and hasn't killed a battery yet. that charger isn't good for things like Lithium batteries etc, I'd only use it on Lead Acid.
