An electrical power supply system for a welfare facility has an electrical power feed unit 12 which feeds electrical power to components in the mobile bathroom. The system includes a rechargeable battery 10 and a generator set 13 including an internal combustion engine, arranged to charge the battery 10, the battery and the generator set being arranged to supply electrical power to the feed unit 12. A plurality of sensors are arranged to monitor at least the state of charge of the battery and the power demand of the mobile toilet, and a telemetry control system 16 receives the outputs of the sensors and transmits corresponding data to a remote control location. Operation of the generator set 13 is controlled dependent on instructions received from the remote location on the basis of the transmitted outputs of the sensors. The output of the generator is set primarily to charge the battery but can supplement the battery during peak power usage. Preferably the peak power output of the generator is less than the peak power demand. Fresh 19 and waste water tanks are included and monitored. |
