How long will my battery last?

[ontheroadagain]

We have just purchased a new Adria Compact SC for collection Jan 2022.
It has a compressor fridge, single leisure battery, and a factory fitted 120w solar panel.
Most of our stays in the UK and Ireland are on campsites with EHU. We do however usually go to France for two weeks in Sept. I know it will depend on the weather etc. but how long can I expect my single battery to last with no EHU?

Impossible to answer - you are going to have to suc it and see.
How often will you refill the fridge? - How sunny is it today? - How big is the battery?
Give it a test while on EHU just using the battery?

If it is factory fitted battery expect it to be small.
what type and size is it.

Need to know the capacity of your battery but even so what 12v equipment will you run from it when not on EHU? E.g a T.V? for how long?
Does the m/h have an inverter?
Solar harvest hours will be more limited in Sept than in longer days.
As said, try it out but don't run the battery down below say, around 12.2v. which is 50% charged.

I don’t know what the capacity is. It is under the front passenger seat so it can’t be big! I will just have to see how long it lasts. I expect I will have to add a second battery at some stage.

How to stay longer off grid (compressor fridge).

Our set up is … PVC van 2 x lead acid leisure battery 1 x 120 solar panel We can just about manage (UK summer/France October) 3 days off grid The 4th day depletes the battery too far. Is there anything we could do without swapping fridge to absorber yo run off gas that would give us 5-6...

I've just checked the technical brochure and your SC Compact looks to come with a single 100Ah AGM battery as standard.

Example: If the fridge goes continually and you use an Avtex Telly for 4-hours and have a shower, plus LED lighting in the van for reading, then I would estimate your usage-per-24hrs to be 50-54Ah.

If you don't use the telly or any auxiliary systems then you'll get just over two days on the fridge alone.

This equation doesn't take into consideration any power from the solar panel but at this time of year you should consider it to be very little (or nowt).

These figures are based on a full healthy battery.

All the best,

Andrew

Wack a second 100ah leisure battery in as soon as you get the van.
