I think you will find the dash socket is only live when the ignition is on, if that is the case then it will not charge the vehical battery either.:thumb:

Hi, Smudger, welcome to the fun site, I concur that you may be plugging the solar panel into the engine battery. Unfortunately a solar panel won't charge your flat leisure battery up - they only provide a trickle charge so the battery needs charging off the vehicle first, then connect the solar panel to it directly by croc clips if you don't have a suitable socke inside the van. This should then keep the charge whilst not using the van .Of course it's better to have the van on hookup if possible -is it at the side of your house? if not a solar panel should help.
Hope this clarifies things a bit. By the way where are you in the country?
Regards, Dave:thumb:

forgot to mention that bit :Doh:
a 13watt certainly wont charge it as its less than 1amp depending on available sunlight.
but it will keep it topped up if there is no other drain on the 'house' battery.

as already said mate, it will only maintain a fully charged battery.

i have a 120w panel on the roof and that only chucks out around 7 to 8amp on a normal english day. about the same as a 'halfords' type home charger.
as most of our useage is on a night it nicely charges the batteries the next day :thumb:

Just as the dash socket isn't live unless the ignition is in the ACC position, a house socket may not be live unless the house electrical panel is switched on. Plug the TV in. If it works then unplugging it and plugging the panel in will supply some charge to the battery.

As others have pointed out, unless the panel is in full sun most of the day, the panel may not be big enough to keep up with some of the fixed loads (perhaps referred to as phantom loads) in some motorhomes. Winter time with the panel in the shade between neighbouring houses, and the output of the panel may be close to zero.

A flat battery becomes a permanently dead or severely damaged battery within a few days - and a flat battery can also freeze if it is a flooded cell type - so getting it fully charged ASAP is the main priority. The panel can't do it so you will need shore power and a mains three stage battery charger

you need to undo the four allen bolts holding the seat in place....two at the back in the runner channel(slide the seat fully forward.) and two at the front down the front face of the seat box.

no other way to get it out.

they might be the 6 or 12 point star type bolts....mine were but i changed 'em for normal allen bolts.
