How far back does the history in your Victron MPPT go and if so what's the charging history the week before that Sunday?
If the van was unused for a couple of weeks howdid you leave it? Did you turn off the leisure battery (if you have an isolator for it)? Did you leave any heavy consumers...
Idid search but couldn’t find anything. This link talks about using the 250 to charge the starter but it only trick charges from solar which I don’t have. Are you suggesting either get solar or disconnecting my battery charger and connect directly to the starter leaving the 250 to pull from the...
no, unless you get a gizmo that will trickle charge the starter, from the leisure battery.
or
you can use one charger to charge the starter battery, to the point that it turns on your dc-dc charger to charge the leisure setup - but you need a large charger and its a faily waistful way of doing...
Suppose I'm thinking that by sealing the leading edge, they're shouldn't be too much stuff gets in there that will stick around. Even with pop top up, anything that does get in should run out with gravity as it'll be slanted downwards.
I ended up going with a similar route (I think) to @Deaky...
The roof fitter, fitted it for me and run the cables back to the seat base...(£200 to fit the supplied panel and run new cable back)
Yes they drilled the roof tub, and also the lower section to get the cables inside.
And used Tiger seal to seal up.
But I redone the cable loop but when I got...
if the dimensions are good,
and the terminals are in the right place, then you are good to go.
the other option is the LOACH i listed above..

as for drop-n voltages. - i would FULLY charge both battery's before putting them in the van, that will reduce the shock on the van when the...

Due to the ever increasing number of flexible solar panels failing, mostly due to being installed incorrectly.
I've added the install guide to the start of this thread...
its not the panel (mostly) - its the poor fitting.
that causes uneven thermal expansion, where the panel is not evenly...

Thank you! Last two questions. As per the diagram below, isn’t there already a fuse for the battery? (Red arrow) and if I just disconnected the white clips and the solar (the green arrows), this should be safe to keep the controller connected to the battery when the solaris not in use?
looks like that charger is for SLI batterys
CB-516 mains battery charger
but it shows 14.3v/13.8v on the Gel setting - which help charge the Fogstar.

defo dont go on the NEG post for the charger. . . . only use the NEG post for a just start.
that becasue the sensor on the battery wont see the power coming in from the charger. . . .
use a chassis NEG point, like ligh bracket bolt or other.
