Since we plan on spending the majority of our time free camping we did a lot of research and thus have possibly made our motor home rather unique. We chose not to have any gas. (The wife has a 'thing' against gas since one self ignited in our first home. Thankfully we were home at the time and avoided damage to the house and ourselves!) Optioning for no gas, not only saved the costs of having it installed and certified by the appropriate authorities we also believe it to be safer.
Our power supply 240v also is not very conventional in a few ways. Most of our appliances will be regular household appliances even though we intend to spend weeks at a time free camping, we believe we have ensured that we will have enough power to run these appliances even if there should be some cloudy or rainy weather.

|The bus roof full of solar panels|
We installed solar panels on the roof to ensure plenty of power but then we had to ensure we could harness that power and after much research, we went with lithium batteries, for many reasons but mainly because they are much more efficient. The batteries are 400amps at 24v Lithium batteries and are controlled by a Dingo controller using SSR unit to take the bulk of the power from the solar to the batteries using a Vitron shunt off a negative cable to show us the amps, volts etc.
|Connecting the Lithium batteries together|
We have a separate 12 volt system and we have connected to solar 80w panel in the control box as well. 12 volt used to be the standard for extra low voltage power systems eg led lights etc.

The higher the current (measured in Amps) the bigger the components need to be. High currents require large diameter cables and fuses, both of which can be expensive. However by doubling the voltage you get double the power (Watt) at the same current.
Sure we could have considered petrol generators, which are a cheaper alternative but they are not very neighbourhood friendly, they are noisy, they are not allowed in all campsites and you need to cart extra fuel for them as well as that creating on-going running costs.We have been at some camp sites that generators run upto 18 hours. Luck has it we were far enough away not to have to put up with these ourselves, though we feel sorry for anyone close by them.
|I am hoping we never need a generator - only time will tell.|
