I'm considering getting a solar panel to recharge the battery when on sites without electricity. I want one that is free standing, not fixed to the roof.
I have searched the forum and spent several hours reading through the "solar panel" threads, but there are a couple of unanswered questions that I have.
Can you still use your 12v system whilst it is being charged?
Can you leave it connected all the time?
There appear to be 2 ways that panels are connected. One is using crocodile clips, the other seems to be via the white 12v socket used whilst towing. Which method is best and can either method be used on all vans?
Thanks

Yes and yes. We join ours through crocodile clips to the battery box the downside is we can not then lock the box shut. Not a problem when the awning is up. ( Maplin suitcase for us)

We have the same one and don't have a problem locking the battery box, but did have to alter the handle where it covers the battery terminals a little bit. The regulator sits nicely alongside the battery and the wires come out through the door. It wouldn't be difficult to cut the crocodile clips off and hard wire the regulator into the van, just plugging the panel into the regulator when required.

Does the Maplin one do a good job?

I have the maplin 13 watt suitcase one and it is permanatley wired in using the supplied regulator. I have also bought one of maplins small 1.5 watt units and leave that plugged in when the unit is in storage to keep the battery trickle charged using the very same wiring supplied with the 13 watt unit. And they both do the job although the suitcase one requires pointing at the sun to get it to work well. The other seems to work in all weather.

What do you want it to do Jeepster? It trebles the amount of time our battery lasts but it does not make us self sufficient. ( I blame the TV)
Don't want it for lights, just tv about an hour a night, water pump and toilet flush, and perhaps a shower or two (pump). 40w.
But that is not answering my questions. Can anyone answer Q3?

My 80w panel is connected via a pair of terminals that are permanently connected to the battery via an idiot proof connecter that in turn is connected to the solar panel via about 5mts of decent thickness orange coloured cable(so that it is visible)
At the solar panel end there is a short spur off the regulator to another idiot proof connector.
In other words I can't c*ck up the connections, the connectors can't come undone as can happen with crocs and the solar panel is removable at any time.(Not by the scumbags, its shackled to the 'van).
I hope this answersm

I think the grey plug gives the option of charging the battery when the car engine is running but would normally isolate the 12 v supplies in the van. With the car engine not running the grey plug would supply the 12v circuits in the van but isolate them from the van battery. So no, I don't think you can connect via the grey plug if you want to use the 12 v circuits at the same time.
Can you not fit an extra socket inlet (not outlet) in the battery box and run the cable in via the mains lead entry. A socket inlet has bare pins like a plug. A plug outlet has matching shrouded holes. It would be a smaller version of your mains lead arrangement.

Having looked at several web sites that sell them, it looks like the majority just use crocodile clips on to the battery terminals. My battery has additional + & - terminals next to the main posts that are threaded, these would be ideal to fix cables on to.

If you have a PV panel, use the croc clips when you have set up your van either on site or at home. Take 'em off when towing. (The panel makes a hell of a noise when dragged along the road!) Q3, forget about the grey plug. All pins and sockets should be in use, and some are live permanently and some only when the engine is running. (Fridge line is one as it takes a lot of juice.)
