I thought it best to start a separate thread on this for the benefit of relative newbies like myself.
I am after knowing typical current draw for "essential use" items when overnighting or indeed staying over 24 hours on a site without EHU (and assuming no engine use to top up leisure batteries)
Lighting - (In my case I can safely say no more than 40 watt per hour max as I am replacing bulbs with leds though I am left with some higher draw fitting that it is just not economic to replace in particular 5 light fittings in the loo! But plainly they have limited use)
Fridge - I expect this to be the heaviest draw
Water pump
TV should I choose to run it. - In my case an Avtex 23" Smart TV. I have an SatFi dome on the roof which I have yet to check out. It will be a bonus if it works!
Sundries - (12v circuits to Truma gas only heater/boiler, also 12 volt circuits to fridge if I choose to run on gas)
There will be some incidentals like electric door step
Have I missed anything?
I do have a small freestanding 150 watt inverter that would allow me to charge my Dell XPS13 notebook or my Ebike battery. Given that I can charge either via the cigar lighter socket in the cab I cannot see that being used more than one hour per day max.
It seems to me that if I run the fridge off gas (I have two 11kg SafeFill bottles) the draw should be very modest indeed unless using without EHU over winter months.
The figures will allow me to ensure I have enough "juice" for two nights without EHU and without engine running which is the maximum I foresee. It will also allow me to spot any excessive current draw via my newly ordered multi-meter indicating a problem.
Of course what those figures will not tell me is the speed with which the 240v charger or running the engine will replenish the leisure battery . I am about to fit a new leisure battery today and explore to find the charger which I suspect is in a panel behind the battery under my driver's seat! If that is a very slow charge that will indicate a need for more leisure battery capacity, restricting 12v use or upgrading the charger.
P.S. One day I might swap to LiPo but prices will need to come down before that will make sense to me (And I have some learning to do - At the moment my understanding of French, German and Italian far exceed my understanding of LiPo technology!!!)
