Regulated and unregulated
I would like to add a portable fold up panel that can top up my caravan solar system and also be used at times to connect to my Anderson plug in my Land Cruiser, to keep my car batteries topped up for the car fridge. The application for the caravan would need to be unregulated ( already have battery charger and regulator in the caravan) and the application for the vehicle would need to be regulated. Can you purchase say a100-120 watt portable solar panel that will do both, or can it be modified, and if so how?
Any advice appreciated.

Can be done, purchase a panel with a good quality mppt controller but make sure it has a connecting cable going to the mppt controller that will allow you to cut, install a socket on the panel side of cable and a plug on the input side of the controller. Install a socket on the output side of the controller and a plug on the connecting car to the car/van.
When you want to charge the car plug in controller then plug your cable into controller.

When you want to charge van, unplug controller and connect cable directly to panel socket.

When you want to charge the car plug the controller in and then plug cable into controller.

Hi,

I haven't purchased any panels for a long time, you could try Mandrakes Solar Power, probably not the cheapest but he has a very good reputation with myswag members and I can confirm the gear I have purchased from him has been very good quality, PS I'm am in no way affiliated with this business.

If you are getting portable ones, definitely look at the semi flexible ones. Much lighter and thinner. I replaced my 2 80W framed ones that were 75mm thick when folded and weighed 22kg with 2 panels that are about 5mm thick ( plus a small block) and about 6kgs. I can lift them and move them between 2 fingers easily. Only a small price premium these days.

Richard,
If your caravan's fixed solar system is being connected to the same regulator as the portable solar panels, you must ensure that the regulator has the capacity to connect both systems. Also if used in this way, all solar panels may need to be matched.

Another way is to operate the portable solar panels independently of the caravan fixed solar system, connecting a regulated input through the caravan anderson plug or through the vehicles rear anderson plug as required.
