Fitting advice

Allow adequate ventilation, use suitably rated battery cables and overcurrent protection, and provide safe AC installation and changeover arrangements. High-power 12V inverters draw very substantial battery current. D.Y Fleet Installations can advise on suitable vehicle electrical installations.
