RV FEATURE If ever the Adventuring Pals need 240V power, they rely on the ute, which has it ' s own electrical setup.
With our simple system, we have been able to go without plugging into a power supply for months at a time. And not surprisingly, our greatest limiting factor is always water – not power.
The biggest reason as to why we can get away with a smaller electrical system is that we minimise the use of electrical appliances in our caravan. Our fridge runs on gas when off-grid and we don’ t have an inverter in the caravan, which can easily and very quickly chew a lot of power. The appliances that use 12V power are the water pump, lights( efficient LEDs), Sirocco fans, the TV, rangehood and USB outlets. We find that we don’ t have to calculate how much power we are using as we have never run it low enough to be a worry.
Even if the caravan’ s batteries did go flat, the biggest problem would be not being able to use the water pump. We would still have a working fridge and stove, thanks to the gas.
If we ever do need 240V power while off-grid, I rely on my ute, which has its own 12V setup. In the ute is another 200Ah lithium battery as well as a 40A DC-DC charger and a 3000W inverter( which turns the 12V power from the battery to a 240V power supply).
