I have 4 panels and 4 batteries
We have the usual fridge,TV satellite decoder, sound system, water pumps, etc but these are all 12V and the only 240V appliance is the aircon and this is seldom used. Open windows and a fan provide ventilation.
Heating is done by Diesel heater on the road and a small fan heater if on power.
We have a 190L fridge (usually on 1 or 2)
So far (3 years) we have not run out of sun (or light). Come close a couple of times but I would move on if a bad weather front is coming or just go a park to get 240V. (plus water etc)
In super isolated areas we are usually just in transit. Always seek a full sun site to pull up during the day and to camp. A hairdryer is run via the inverter sometimes for short periods.
I keep an eye on the batteries and find if the satellite dish and TV used for a long period at night the batteries can be in very low 12V in the morning but are quickly returned to 14V by the time we stop for lunch.
Try to shower in the morning so that pump draw down is quickly replaced by solar.
If the weather looks like being fine I don't fret at all about using the power. I always monitor the weather to help manage power.
If travelling, we would go to a park at least once a week for water, washing, etc and to give a boost to batteries via the charger.
