Extra Leisure Battery or Solar Panels Off Grid?

Simple job to bring one cable from linked solar panels through a roof is by using a boat deck gland, which can be hidden under the panels.

That looks like about 450Wh per day overall. At this time of year you expect the equivalent of about 1.75 hours of sun per day, so that'd be what I'd expect from 750 to 800 watts of panels.
What surprised me is that the graph is backwards. Why does time go backwards?
Have to say no idea lol

If you mean the numbers at the bottom of the chart they are dates not times 👍
 
Just a single panel on the roof (cant remember if its 100w or 120w) and this MPPT controller.


The controller is a fair few years old now or at least mine is and I remember there was quite a buzz about them when they came out and lots of us bought them. Its brilliant as it shows you the battery status, whats going in and if you wire sockets off it then it shows you whats going out.

I'm hopeless and DIY practical stuff also so I bought all the gear myself, panel, corner fixers, solar cable and the MPPT Controller and got my Mr Motorhome Fixer guy to fit it all. I think he did use an existing hole to run the cables through. Satellite Dome I think. Took him two or three hours for which he charged me about £90 I think. All in was about £300. I wouldnt be without it now. Absolutely essential for us as we often spend weeks off grid in the same spot in Spring and summer. Pretty useless in winter really.
 
@Phil M - I may have missed it but you mention "gas heating" - is it the sort that has a "fire" and you just need 12v to fire it up, or is it a blown air system like I have in my Adria? Mine uses quite a bit of 12v power for the fan.

I have a 200w solar panel on the roof and just one 110 Aph lead acid battery, and I can usually stop in one place for up to 4 nights in winter, 5 if it isn't sub zero temps.
Just catching up with replies....yes, blown air heating from a Gas Heater on 12v....your system sounds good to me....I'm going off for a few days soon to work out what life I can get currently....thanks for replying....
