I don't understand this solar lark.
On my van there is a panel on the roof. In a hab cupboard there is a switch for the panel to divert the charge from either engine or leisure battery (i'm told).
When i left the van Xmas day i made sure the switch was on engine battery.
Came back 4 months ish later engine battery flat as a pancake.
What am i not understanding?

Is that switch for the solar or from which battery your 12 volt systems will be supplied from as is the case for a similar switch of ours.
If the later then anything 12 volt running the background would have drained your starter battery.

Unfortunately it's not uncommon that Autotrail mis label the two way switch so you are charging the hab when you think you are doing engine, or vice versa.

Over the midst of winter, the charge from solar will have been very low. There is an ongoing drain on the engine battery for alarm systems, trackers. Not much, but it can be enough. Solar may, just, not keep pace. My system now trickle charges the engine from the leisure using a battery master device (works off a voltage difference), with the leisure topped up by 100W solar. Over winter that 120Ah leisure used over 80% of available charge, before eventually recovering

Do you still have the Imala,
Some Imalas (like mine) were wired wrong at the factor so leisure is engine and engine is leisure.

turn your sticker upside down

You can soon tell by sticking a volt meter across the leisure under the bench and flick to one or tother on the little switch under your PSU when suns shining

Thanks.
The solar panel was supplied and fitted at Don Amott. They wouldn't wire incorrectly..................would they?
Need to find someone with one of those meter things you talk about. And switch the switch upside down

Still got the Imala. New van supposed to be delivered end June.......we will see.

You can buy “one of those meter things” at Halfords or off eBay. I’m sure you can afford it,if not we could have a whip round!

Or you could flick the control panel on above the door, then see when the leisure says "charging"

If you did have the whip round could i take the money and i will promise to buy "one of those meter things". Where on earth (no pun intended) i would stick the end/s is beyond me.
