To connect Solar Panel kit to Anderson plug on caravan

Hi hope someone out there can advise - We have purchased a 2 x 80 watt solar panel kit that has alligator clips on the ends. If we replace the alligator clips with an anderson plug fitting can we plug it directly into the anderson plug on the caravan that connects to the car to charge battery whilst we are driving?
thanks in advance

This could be done.......IF.
1. The solar panels have an inbuilt solar controller.
2. The caravan anderson plug connects directly to the battery.
3. The connecting wires from the van anderson plug are heavy duty.

If all this is so then the connection would be simple and easy.


I used to have a handle on life, but it broke.

Cheers Dodg.

Thanks Dodg and Kevin B1
All the wiring from the landcruiser to the van has been uprgraded by reputable auto electrician because what came standard in the cruiser and jayco van was very inadequate. So the wiring from the car to the new battery and new battery charger in the caravan is all good and working very well now.
I have in my hand the instruction manual 'For solar charge controller' which is installed in the solar panel kit. It is EPRC-ST series and has technical info, is that important to know before connecting to the anderson plug?
thanks again

If you dont have an inbuilt controller, you will need one or risk over charging the batteries.
Connect to the panels by anderson plug, run the required length of wire to the input side of your controller and run a shorter cable with anderson plug to the plug on your caravan, or put the controller near your battery.
Have a read of the 3 links below and take note of the required wire sizes.

Yes if it meets above, but on the cable buy 2 Anderson plug and place them in the cable as a joiner, this way you can use the Anderson plug to plug into your car or connect the two together and you can still use the alligator clips.

This is what I do anyway.

Regards

2 ways of connecting an anderson plug.
1 is crimp, proper crimpers for the job not just multi grips or
2 solder with a big soldering iron or butane torch.
A quick call to your local auto electrician might help if you dont have the facilities to do either method properly.

No , you need a large crimping tool or solder, I brought a tool from ABR Sidewinder, but it's a tool that you will only use once or twice. just take it to you local auto sparky and they will have the Anderson plugs and will fit them.

Cheers

Thanks for all that info. Hubby Steve will take solar kit to our auto electrician and he can do that for us. And he will know if we have all that we need.
We were thinking we may have had to put another line into van but now no need to.
thanks so much

Hi Watson

This morning I just refitted an anderson plug to my car for the camper. I used one of those cigarette lighter/butane torches to melt the solder into the connectors with the wires sitting in there.

These torches are available at hardware stores and are loaded with what looks like a bic cigarette lighter. Instead of a yellow flame (low temp) they give off a blue flame (higher temp).

I keep this lighter in the camper as it is rechargeable and click start and good for all those handy jobs like melting the end of ropes, starting campfires with dampish wood etc.

Thanks Serendipity, what a handy gadget.
Will get one and keep with us. Never know when will come in handy. I have been know to use the kitchen gas lighter to soften black poly pipe to put on fittings. This will be much stronger heat and work better for that job too. And who knows what else?

Getting off the subject a bit, but use boiling water (if you can) over the poly pipe to soften. Does not distort like a flame can. Have a pair of leather gloves ready as that fitting will be hot. Can use same method to remove without destroying fittings.

I like that little 'butane' torch though. On my Xmas list.

Watson,
You ask:
"can we plug it directly into the Anderson plug on the caravan that connects to the car to charge battery *whilst we are driving* "

Why not allow the car Alternator charge the caravan battery
reason being; the amps will be far greater from the Alternator than is generated by the solar system *when your driving*

I would connect the solar system to the caravan battery via a suitable regulator independent of the vehicle Alternator charging system, so when your parked the solar system will maintain the battery charge.

Sorry but my explanation is a little misunderstood. The *whilst we are driving* relates to 'the cable from the caravan that plugs into the anderson plug fitting on the car and that charges the battery in the caravan whilst we are driving'. We don't want to change anything there but we were wanting to be able to plug the solar panel into that anderson plug fitting on the end of the cable that runs into the caravan while we are camping so we can continue to charge the battery.
Sorry about my explanation but it was clear in my head! I have the same trouble explaning what I mean to my hubbiie Steve. We talk different lanuage :-)
