We’ve just done that run. We put a 4 pint of frozen milk in the fridge section and a cold pack previously frozen. Survived the crossing no problem. The milk hadn’t thawed either!

(Sorry did I say milk ?, I meant errr Fruit Juice…. Mr Customs man)

can i just run 2 wires (6mm) straight to the fridge with a 15amp fuse. Has any one got a wiring diagram for a Autotrail 2018?

What side is your fridge on...if it's the right then..from memory the tribute was the same as the Imala which I re wired...
Check the right hand pillar behind the drivers right shoulder..is where the cables run. Then split to go down to a fuse box in the floor behind the drivers seat and also run up and along the cupboard backs.

I think the fridge ignition fuse may be in there. But the relay in mine was in the battery compartment near the door step buzzer one.
I found the fridge averaged about 8-9 amps per hour

Isn’t just leaving a large bottle of ice in the fridge easier?? :getmecoat:

I thought the whole idea of lithium was you could use 90 per cent. If the OP only uses 220 out of 300 then surely that's the reason for having lithium in the first place?

Hmm, most (?) fridges have mains elements of 185W.

At 12V, thats a current of 15.5A.

On a 30 hr journey, thats 462Ah.

But using a load factor of 60%, that equates to 278Ah.

That ignores inverter inefficiencies and embarkation/disembarkation time.

Conclusion: you need more battery capacity if you intend to go down this route but, as others have pointed out, filling the fridge and freezer with bottles of frozen milk/water is a better strategy.

Lenny HB Sorry for being thick but even allowing three hours messing about would still have more than ten percent left. How often can you use the ninety percent that justifies the expense of lithium? Without damaging the batteries?

When we crossed at the end of August we froze a 6l of water then transferred it to the fridge after boarding and was still partly frozen when we stopped for our first night in Spain 30hrs later.

Seems to me the work involved in keeping the fridge on throught the journey is far in excess, and not even guaranteed to work, when a couple of frozen bottles of water will do the job quite adequately.

Ever since lighting was by Calor gas.
When we crossed at the end of August we froze a 6l of water then transferred it to the fridge after boarding and was still partly frozen when we stopped for our first night in Spain 30hrs later.
Keeping the fridge powered up seems like a lot of unnecessary fuss to me.
I freeze milk to utilise the space better.
I would only take enough perishables for the first day anyway (although I rarely take any perishables at all) and rather enjoy stocking up after arrival.
I wouldn't take any fresh fish or meat (especially fresh chicken) with me and can't see why anyone would need to.
As for frozen food..................I discovered that they've had shops abroad for many years which sell it. (y)

as i said just seeing what the art of poss is. its drawing 9.9amps. and as two on tour correctly said 132 w. (not sure where i saw 55)

how long will 300Ah lith last
That 132W won't be for 100% of the time, because the thermostat will switch it off and on as required. So maybe 55W was the average consumption over a 24hr period. But that does sound a bit too optimistic.

Whether the 300Ah will last depends on how long the voyage is. Is it a 24hr or 36hr voyage?

Worst case is if it's 10A max current consumption, then that will last at least 300/10 = 30 hours, but then the batteries will be totally flat.
Best case is if it's 55W average current consumption, ie 4.6A average, which will last 300/4.6 = 65hr. So the 50% level will be reached after about 33 hours.

how do i tell the fridge the engine is running lol
Depends on the fridge. I presume it's 'Automatic Energy Selection' (AES). But does it have a manual override selection switch, like mine, or is it fully automatic with no manual selection possible?

Taking them down below 20% regularly will shorten their life but not enough to worry about and 10% will be OK the odd time. But if it goes any lower you will be relying on the BMS to protect them. Not a risk I'd want to take.
