Enerdrive 12V 40A+ ePower DC2DC/MPPT Charger

Enerdrive ePOWER 40A DC to DC Charger: Intelligent Dual-Input Power

The Enerdrive ePOWER DC2DC+ Battery Charger offers a streamlined, intelligent solution for managing auxiliary power in caravans, 4x4s, camper trailers, and marine vessels. By integrating a high-performance multi-stage DC to DC charger with a dedicated Maximum Power Point Tracking (MPPT) solar controller, this unit eliminates the need for multiple separate charging devices and complex external relays. It is engineered to automatically prioritise and manage power from both your vehicle alternator and your solar array, ensuring your house battery bank remains optimally charged while operating off-grid.

Seamless Dual-Source Charging Integration

This advanced power management unit features two totally independent DC inputs. While the vehicle is running, the charger utilises the alternator to rapidly replenish your auxiliary battery. It is fully compatible with both 12V and 24V vehicle systems, making it suitable for a wide variety of touring and commercial vehicles. When the engine is turned off, the system automatically transitions to harvesting energy from your connected solar panels. This fully automatic selection process ensures a continuous and reliable charge without requiring any manual intervention from the user.

Integrated MPPT Solar Controller

The built-in MPPT regulator is highly capable, handling a maximum open-circuit solar input of 45V and up to 800W of total solar power. This high-efficiency tracking technology maximises your solar yield in varying light conditions, which is an essential feature for extended off-grid travel. By combining the solar regulator and the DC to DC charger into one compact footprint, you save valuable installation space while significantly reducing wiring complexity and potential failure points.

Advanced Multistage Charging for Deep Cycle Batteries

To protect your investment and maximise the lifespan of your deep cycle batteries, the Enerdrive 40A DCDC charger utilises a precise, multi-stage charging algorithm covering Bulk, Absorption, and Float stages. It supports a comprehensive range of battery chemistries, including GEL, AGM, Flooded, and Lithium. For specialised off-grid power systems, it also allows users to program a fully custom charging profile. The integrated, fully programmable LCD display provides vital real-time monitoring of charger status, active power source selection, voltage, and amperage.

Key Features

• Dual independent DC inputs for automatic engine and solar charging
• Integrated MPPT solar regulator supporting up to 45V/800W input
• Selectable charging algorithms for GEL, AGM, Flooded, Lithium, and custom setups
• Compatible with both 12V and 24V vehicle alternator systems
• Robust M6 screw terminals for secure, high-current battery cable connections
• Temperature sensor included for highly accurate, temperature-compensated charging
• Thermo-controlled fan cooling to maintain peak 40A output in temperatures up to 40°C

Reliable Power Management for Australian Adventures

Designed to withstand demanding conditions, the unit includes sophisticated load-based regulation. This intelligent feature prevents the charger from incorrectly holding the battery in an absorption stage when DC loads, such as fridges or lighting, are active, thereby preventing overcharging and subsequent battery damage. Whether you are outfitting a touring 4x4 or upgrading a caravan electrical system, the EN3DC40+ delivers consistent, safe performance. The rugged housing and heavy-duty M6 terminal block ensure highly secure connections, effectively reducing the risk of voltage drop or loose wiring when navigating corrugated roads.

Ensure your auxiliary batteries are always primed and ready for the next adventure. Upgrade your onboard power system with the Enerdrive ePOWER DC2DC+ charger today to experience highly reliable, automated off-grid energy management.
