Ok, that's exactly what we do.
If you have a standard leisure battery then generally a 100W panel (with built in controller) will do, unless you have unusually heavy power demands.
The solar panel (with controller) connects to your leisure battery (wherever that is).
But this also depends on...
Just for anyone browsing...
Got an Ecoworthy fold up 100w solar panel. Fits on dash when parked - see pic above posted by DellMassive - that is the one.
In full sun, when solar panel is on dash it supplies about 20-30 watts which is more than I was expecting as cells not angled exactly and are a...
Hi thanks for reply
The inverter is to run a small slow cooker, about 100w and our hot choc machine at 500w, from the 240 sockets in van, when we aren’t on EHU.
I would say 48hrs would be the max we would be in the van without driving or plugging in to EHU.
Building van to use in all seasons...
Hi all, quick question ref a 100w solar panel that I’m having installed. I’ve also asked for a dometic fridge to be installed. Would the 100w panel be enough to keep the leisure battery topped up and keep the fridge going? Especially over winter.
...blocked heater matrix I don't have time to deal with before a long roadtrip in half term. Myself and MrsR have the lovely heated seats in the front but I'm pondering a heated fleece for an hour or so to help the younguns in the back. At about 100w should be good off the little 150w inverter...
...figure to look at here is "P max" as this is the highest overall power the panel achieved. I'm assuming from the figures you have a nominal 100w panel, so on the "2 days ago" you got very close to ideal with a peak power of 90w, but the days before you got very low values in the 10-15w...
...Plugged all back in…..Vic shows nothing
Unplugged tested cables ….shows 22-24v BUT no Amps
Tested cables straight from PV same as above
Tried 100w portable PV …. 23-24v BUT no Amps
Attached portable PV to Vic …. Nothing
PV out in garden …. 22-24v BUT no Amps
PV plugged into battery bank...
I tried to use 40w on the dash of my T-Cross whilst lockdown was on - not good enough. I then used a 100w panel that just fitted across the dash which gave enough juice to keep all the electrics ticking over whilst being used. The screen does cut down the output considerably so I don't know that...
the only draw back with these portable power packs is the slow recharge rate from 12v. . .
all are limited to the 100w / 8A input limiter, as above this the 12v plug socket will melt.. . . .
in a nutshell they can take longer to charge than drain down - so net effect is they run flat over the...
If it's 100% sunny you can get 6A ish charge from a decent 100w setup.
Assuming you have a 100ah AGM battery.
You might be able to get a day or so depending on your loads.
So start with the 100w kit and see how you go.
Future of upgrades could be....
A second 100ah battery for longer run...
just add in a MC4 fly lead to the 75/15 controller.
then when camping, just plug it in. . . you will get power from both 100w panels.
ie:

and . . . add something like these in with your existing panel.

...going around in circles as to how to progress. I also want around 300W so need to use more of the roof anyway.
Expect that Hillside quote is for a 100W bonded, with an unknown controller.
I spoke to them about solar panels when I purchased mine and they were too restrictive on what they...
