What Can We Create for Your Vehicle?
Whatever your needs may be, we’ll come up with the most effective way to meet them. Previous bespoke designs have included an installation in a VW T6 Transporter that provided the client with a mobile phone and credit card machine charging station, as well as charging facilities for battery operated power tools, diagnostic equipment, and lighting. The system was also configured to monitor the vehicle battery system and accessories, such as light beacons, interior lighting, and front LEDs all at the same time while on-site.
The system runs a 3000watt pure sine wave inverter, for internet and 240-volt mains for the computers and diagnostic equipment.
