There was a company in your area (Holroyd) that used to sell solar energy systems for farms. They used a 24V DC system and had a few useful computer power supplies. I remember contacting them in the mid 1990's for a mobile product distributor that ran their trucks on 24V DC. I think we ended up using their 24V to 240V converter, so one could use a conventional PC power adapter. The main problem was ruggedising the PCs and things for on-road use. Look in the yellow pages for Solar Energy (would you believe).

I have a 24vDC PC thats going in a truck. I want to ensure there is a reliable power supply and ensure that if the power is interupted the pc will not shutdown. I can source a 24v Battery with enough juice to run the pc for 15 min when the truck ignition is off. What Iam unsure of is the wirring and other electronic gear to ensure that whilst the truck is going (running) it is using a regulated 24v of the trucks electrical system and trickle charging the battery if it is not fully charged and if the truck ignition is off it uses the batteries and allows the users to shut the system down gracefully. Any help is appreciated.
