Power the caravan with the battery

[Norrientes]

Hi,
I plan to be off grid and have a leisure battery and an inverter in the caravan, I would like to know if it’s possible to use a

Double Dragon UK Caravan Trailer Hook-Up Lead, Fly Lead, 13A Plug to 16A Socket Adapter, 230V UK Electric Mains Adapter, Caravan Trailer Campervan Site Connector, With 3 Pin UK Ease Fuse Replace Plug​

To plug the 13A plug into the inverter and the 3 pin male socket into where you would normally plug in the electric hook up to the outside of the caravan, therefore using the battery to power the whole van?

Thank you

It would/should work OK I believe but you would need to switch off the battery charger and make sure that the fridge isn't automatically switching to 240v.

What do you plan on using on 230v

Thank you, I just to power the whole caravan using the battery

Thank you, how do I make sure the fridge isn’t switching to 240v?

What do you plan on using on 230v

I just want to use the battery to power the caravan, the battery isn’t set up to power the caravan completely, only some lights and the water…hence wanting to use the battery to power the mains input…

Any appliance you use will have a spec label somewhere.
You need to see what the input watts are.
Every 240 watts input will draw 20 amps per hour from your batteries plus maybe 5% to 10% more for inverter losses.
I my opinion, not worth it when many things, TV, phone charger etc, can run on 12v directly.

Probably a bit innefficienct to run some things as you will be turning 12 into 240v then back to 12v again for some things. Also as pappajohn has said you will have to be very careful what you plug in and will need decent thickness leads from the battery to the inverter. To get a better idea could you give some examples of what power the inverter is what standard it is and what you are thinking of plugging in. You can of course plug it in it's whether its going to work!

If it's a 3 way auto fridge (12v, gas, 240v) then make sure it's not on auto and select gas.

Ok, thanks. My set up is as below…
1 battery and clips to inverter
2 inverter close up
3 potential plan- hook up inverter to battery plug connecting cable into converter, plug out window into external hook up input.
4&5 other snaps of electric set up

I am hoping everything will work as if in a normal hook up ….

Is that a bit more clear? Appreciate I need a 12v to 240 conversion as opposed to 230

Finally the caravan is an Eriba Troll 550 GT 2003 model for those interested
Thanks again!

Oh and there is a motor mover on it too- god knows why, I can spin it with one arm!

I wouldn't be using a 1000watt invertor with "clip on leads" such as those shown. Asking for trouble.
Also it is a square wave invertor, not pure sine wave. A lot of appliances will throw a hissy-fit when powered by that.

 

[Lenny HB]

To run a 1000 watt inverter at full power you will need another 4 batteries, you shouldn't discharge lead batteries at more than the C5 rate which is 20 amps for a 100ah battery.

As said Croc clips are down right dangerous and shouldn't be used on high current loads. Also a modified sine wave inverter is not suitable for electronic equipment.

 

[Tigger-Tim]

If you try running a 1000W mains appliance through your setup, it will try to pull nearly 100 Amps from your battery. You'll damage your battery very quickly.

If you must do something like this, it would be much safer to get a powerbank - eg. ecoflow, anker or jackery.

PS. at 100A, a normal lead acid battery like this will be discharged* in 30 minutes.

*lead acid batteries don't take well to being discharged to much more than half their nominal capacity.

 

[The Wino]

As others have said connecting with crocodile clips isn't really very good you will have an unreliable connection to the terminals and an exposed bit on the end of the clips which could short if anything comes near it. The cables on the clips are a bit thin.
Mains electricity is alternating current on a sine wave a lot of electronic equipment ( TVs computers etc) can be affected if the inverter isn't a pure sine wave one I don't think yours is.
The inverter is rated at 1 kw it probably will actually supply a little less. Most appliances like hair dryers, kettles,heaters etc will not work as they run on a lot more than that.
At 1 kw it would flatten the battery very quickly and probably dammage it as the discharge rate would be too high.

Reading your post, it is clear that you don't understand that running an inverter the way you suggest cannot work. You will flatten the battery extremely quickly with the inverter and won't be able to recharge it without plugging into a mains socket on site or at home. Better to run all that you can using 12v versions

For instance running your fridge on the inverter you might get a couple of hours. Run the heating (it won't) would flatten the battery in minutes. It also couldn't boil a kettle
