How long will the battery last

[Chadders]

I have a new leisure battery and 120w solar panel also new. Thinking of the possibility of using some basic smaller sights and using a pitch without hook up. Also cost saving exercise.
What is a reasonable time for the battery to last running the tv lights etc for about 4 hours each evening. Also pros and cons of using the fridge on battery or gas and also heating and hot water?
Thanks

Your fridge will only run on Gas, off Grid, ( no EHU) most modern vans will use 12 volts to power, heating and hot water, , water pump for showers, sink etc., on the control sides.
If your internal lights are LED then they will draw a small amount of power.
The TV, is the biggest power draw, depends if it is a 12 volt or 240 volt going through an inverter ie 12vt volts to 240 volt.
Many folk can last a week plus, sitting outside the caravan with a headlamp on their head reading a book.
Others have all the lights on , etc. the only way to check is to go to a EHU pict and not use the power, just use the van.

We go off-grid nearly all year round.
Charging the battery obviously depends on the weather, the amount of daylight hours, cloud cover etc. With a bit of thought you can be off-grid for several weeks at a time.
Heating, hot water, fridge run on gas. Far more efficient. We actually find the fridge cools quicker on gas.

At present looking at a TV 22inch Avtex /Cello 12v/24v /240 are these better suited for your battery because we are on a meter system .

I don't understand your concern or point. What do you mean by a meter system?

Just looked at the specification and uses no less power than our LG which is far cheaper to buy. If you are on a metered supply will make negligible difference to your consumption cost

Power consumption a modern tv is minimal, but if you have solar panels to charge the battery it will run on 12v, but since your pitch is hooked up to EHU what are you trying to achieve. You could turn off EHU and run on 12v battery supply which might save a small amount on your metered charges. But frankly is it really worth it on your pitch.

When we started out in July last year we thought for now we will put £30 on the card and after the fourth time stopping there we was watching Dog house and everything went off . That why we are looking at a 12v Tv and we have Solar panels on roof .
But now everytime we go we made a note always put money on the card then if we run out put the card in everything will be okay ( It my first time with this system )

A basic 22” 12 v tv will give you at least 25 hours . As Hutch said there are other things using your battery.
When your 230v dies do you go onto gas for everything else?

We currently on a CL payg 230 v. Experience here tells me this time of year £6.00 will easily last 24 hours. Just check the meter each morning.
The TV you are looking at is probably 4x the cost of a cheapo 🙀.Is it worth it🤔

All of our stuff TV, stereo, router etc runs off 12v.
When on EHU it's just the fridge and water heating as the battery is charged from Solar. We spend up to 3 weeks away and haven't had to use the battery charger in the last year.

Beachball, if you already have a well functioning television then the cost of replacing a perfectly good tv with a new Avtex will pay for an awful lot of metered electricity and you will save very little on the metered cost in the process.
There will be other ways to save on electricity such as only putting the water heater on when you actually need hot water rather than all the time; if you need the blown air heating, rapidly getting the van warm using gas then using electricity to keep it at temperature; making sure that any hot air ducting that runs under the van is insulated etc.
