Help with set up leisure battery and etc.

[Snakelimit]

Hi everyone, I looking to replaced in my RAC T6 AMG battery and would like to help with an upgrade to a Lifepo4 battery with a new DC-DC charger, inverter, and other accessories.

My primary requirements are a battery that can provide power for up to four days to run essential appliances like the fridge lights, night heater, and water heater. I also need an inverter to power the kettle, hair dryer, and possibly an air fryer or induction cooker.

I would like to have a backup power source like solars as well, but I’m still undecided about whether to install a pop-up roof or not. However, I would appreciate having a backup option just in case.

I’m open to suggestions for the best battery and power system to meet my needs. I’ve been considering the Orion XS 50A DC-DC charger, but I’m also open to other recommendations.
Originally wanted install in double seat but recently my wife complain about how comfy it is and we will need change to singles one for her and wonder if all would fit in single etc.
Thanks for your help!

Please see below my current set up

4 days off grid just on battery power? fridge , lights, night heater, water heater, kettle, hairdryer and hob
Have you calculated all that ?

As mentioned you need to workout your power usage. That is the first step before designing the system. You will need a very big battery to cope with 4 days, including some pretty heavy inverter use, with no other charge source. Or you will need to run the engine to top up - are you stationary the whole time or driving each day? Have a look on Nohma.com for some excellent system design guidance.

No not really, 4 days are just maximum what I would stay in case my wife don’t feel well and it’s not like we will use all them each day except fridge, it’s hard to do this until you actually out and use it

To give you an idea, 2 years ago we went to Lyme Regis to stay on a dreadful 'Long Drop Loo' type of camping field.
We didn't think it could get worse, it did, our solar panel packed up on day 1.
Fortunately our old 200Ah Roamer battery was fully charged on the way down by the Orion TR30 (Now replaced with Orion XS50)
We used a 2000watt induction hob, fridge permanently on, lighting, diesel heater, hair straighteners, toaster etc. 2000 watt pure sine wave inverter installed.
We went out once to the beach which put a few Ah back into the battery. Apart from that no other power input.
After 5 days the battery was down to 15%, the lowest I have ever taken it. The solar usually tops the battery up nicely, don't like to manage without it, but we had to!
What you want is very doable, it just takes up a lot of space and can be expensive!
