Fully off grid living is achieved with the installed Solar System, the LPG generator and washing machine. The solar system, associated battery back up and invertors are all locally acquired.

The batteries are also charged by the generator at 90 amps. Charging is also achieved via a double isolated battery charger meaning system is not directly connected to the 230V grid.
The truck has been fitted with two 500 litre tanks one for the waste water and the other for fresh water. When the onboard waste tanks require to be emptied a macerator pump transfers the waste to the truck tank and emptied at designated dump station which generally incorporates a potable water filling point.
