The Enerdrive ePOWER EN1120S-X is a professional-grade 12V 2000W true sine wave inverter with integrated AC transfer switching, purpose-built for serious off-grid power management in caravans, motorhomes, and 4WD setups. Delivering a clean, stable 230V/50Hz output with total harmonic distortion under 3%, it safely powers sensitive electronics — laptops, CPAP machines, medical devices, and modern variable-speed appliances — without the risk of damage or erratic behaviour associated with modified sine wave units. With a 4000W surge capacity, it handles the start-up loads of compressor fridges, power tools, and air pumps with ease, while its wide 10–16V DC input range and adjustable low voltage disconnect protect your battery bank from over-discharge.
Designed for Australian conditions and 230V/50Hz compliance, the EN1120S-X is the go-to inverter for caravanners who want seamless transitions between shore power at a holiday park and battery power on remote free camps. The built-in AC transfer relay automatically switches between mains/generator input and inverter output with minimal interruption — ideal for running a 12V caravan setup with a mix of solar, battery, and campsite hookups. Its compact, wall-mountable aluminium housing fits neatly into caravan battery bays and 4WD rear compartments, while the remote on/off capability means you can manage your power from the comfort of the van without crawling into the battery bay. Enerdrive, now part of the Dometic group, backs this unit with strong Australian dealer support — a trusted choice for serious off-road travellers and full-time grey nomads alike.
