Yesterday we left @ 0.11.00 for a cycle tour, returned @ 16.00 hrs. Before leaving I popped my single 100w jackery solar panel flat on MH roof. Unit read zero, in return 39 %. Not bad says I, and unit used this morning same setup in motion again today, unit @ 49%.

With leisure battery @ 13.8V, both eBike batteries topped up using 2000W inverter and ready for another tour today.

Looks good !
Inevitably a fridge question.
Could you feed your motorhome using the normal input..
To only run your 3 way fridge off electic.
Jackery and solar providing the power.
I assume lights water pump would be powered by the 12 v system
My dometic fridge claims to use 190 watts on electric which is lees than 1amp ?
It seems that it will use this power about 2/3 rds of the time.
I suggest that if you are stood from say 3pm then for a few hours at least the drain on the jackery battery will be less due to solar input.
Indeed also overnight even a 3 way fridge will be slightly more dormant (11pm to 7am).
Interested as our gas option on the fridge is literally on the blink.
A simple repair would be good but I baulk at buying and fitting a new direct replacement.
We have a pair of leisure batteries so a reconfiguration using a compressor fridge would be considered but that has significant internal structural issues.!
Ps the blinking fridge has stopped blinking temporarily but I am concerned about the 2 internal temperatures

Jagmanx, to answer your question about running a fridge off solar/ power bank/leisure batteries.
I currently do it on good sunny days swapping between a ecoflow power bank charged by 260w panel and the motorhomes inverter with two lithium batteries and 600w of panels on roof.
Fridge/freezer pulls about 270w, about 20amp through a 12v system so quite a heavy drain.
With the sun at the moment more than possible but don't expect it to run all night.
 
This is jackory hooked up to 230 and the mrs sewing machine in operation
three other pice jackory on charge from two solars with phone/pad getting charged
draws 350 ish when fridge on mains but very happy with this kit

Neil I'm going to couple one up but at present doing like this as I'm changing the van when I get back pissibly
it was just to give an in sight to how it can be used with various methods asi find it very versatile

I must be missing something with these. If you have decent battery bank and rooftop solar why can’t you run totally off grid all summer without a power brick? I manage fine approx 7 months (minimum) in U.K. and I use an inverter to charge my escooter?

Nabsim, I think you might be referring to me with a decent setup.
I only have a power bank because I have an off grid property in France and need the versatility of mobile power.
So as I have it I might as well use it and get free electric while the sun's out instead of using gas to run the fridge, do all cooking and hot water.

I wasnt referring to anyone in particular, by decent setup I was thinking a lot of folks who go off grid would have at least 300W. Was thinking maybe it was the battery side letting them down but no common factors yet. Unless it’s extra electrical appliances as does seem a trend these days.
Needing to use power tools or use at home out camping or anywhere you wouldn’t normally get power is the ideal use. Same if you live somewhere that experiences frequent power cuts.
Same as always though everyone is different with different needs, it just puzzles me why so many buy them, can’t decide if it’s just new gadget or if YouTube influencers really do have that much power lol

Gadget Fever :)

I think you mentioned somewhere I did a DIY version? I kind of did when I used to do shows and so wanted self-contained power in the marquee. Basically a Battery in a Battery Box, with a 12V Socket, USB Socket, and an Anderson Connector that is used to connect either a charger or an Inverter.
It would be so simple to just have the inverter and/or the charger inside the battery box and that is all the Jackery, Bluetti, EcoFlow, etc are... a nicely packaged group of components.


FWIW, I used one of these DIY jobbies at a show a few years ago, with an old Starter Battery inside (as just wanted basic low current power) and lots of people wanted to buy the box as it was a lot cheaper than these Jackery type systems! Ended up selling it and made a few more to sell but shows then stopped so still have them :(
 
Faffing about, Jackery now running the fridge, folks coming round tonight and cooling 🍹. Stuck it on without solar added @ 13.00 hrs @100%, see how much is used by 14.00 hrs.11D75C13-589F-4D46-81EF-5E17F0BF159C.jpeg
 
Practising my (non-existent) maths skills now so please correct me if I’m wrong. Terry has his fridge on and it appears to be drawing 134watts. So with a 12v battery system this is near enough 11amps. 11 amps for one hour from an 80ah Jackery battery equates to 14% of battery useage (ie leaving 86%) so presumably the extra couple of % comes from the solar input - would this be right?. So in theory,ignoring solar input, there is a max 7 hours of Terry size fridge time in the Jackery If you want to run the battery right down?

For comparison I have a largish fridge/freezer (142 litre) in my van. When I use this off my 220ah lithium battery set up with a 2kw inverter the fridge draws around 20amps less whatever the 320w solar array puts in.
 
Tony yes.
Ignoring your lithium set up will give you 11 hours But.
1 you have lots of solar.
2 what sort of fridge is it and will it draw less power overnight. Given the power is draws it would seem to be an absorption fridge.
If it os a compressor I think you have loadsapower
 
Running a 3-way fridge off a Battery overnight is going to be a no-no unless you spend a lot of money on a lot of battery power. If that is a long-term aim, it would be cheaper to replace the 3-way with a Compressor Fridge!

I'll thown in a couple of comparative graphs of my own 3-way Thetford N180 (180L?) Fridge/Freezer compared to the replacement, a 240V Compressor Fridge/Freezer (140L?)

Taking both the power when running and the duty cycle, a Compressor unit uses around 1/7th of the power of a 3-Way on Electric.
 
Gents, after my second post, I coupled up the solar panel, % gain was quickly evident and unit is now back to 100%.

I am really not trying to prove Jackery is the mutts nutts, just some feedback on what can be a food saver is LPG is hard to source.

Nor was I influenced by a youtuber for motorhome use.

Yes, thanks David.
3way on 240v is simply nogo IMO.
If pur 3 way pops its clogs I will replace with a compressor type..
@runnach . Terry Interestong to muse over reducing gas usage I know we use about 1 lite a day with fridge on gas for ay least 16 hours.
A bit more when very hot.
So 1 tank lasts 3 weeks and we look to top up (having switched bottles asap..always within a week.
Might work well 4 U in Morocco although I have read that Mr Heath Robinson has solutions
