Enerdrive ePower DC to DC Battery Charger - 40Amp -12 Volt - EN3DC40+ 
12 or 24 Volt Input and 12 Volt Output Version - (Two Inputs One Output)

Purpose:

This 12V 40A DC to DC (battery to battery) charger, can charge your deep cycle batteries from your alternator whilst you drive, and it can also charge from your solar panels.

Once your vehicle’s alternator has charged your start battery, extra charge can be transferred from the start battery to your deep cycle battery bank, which means you should have more battery power when you arrive in your van or motorhome to set up camp. Solar input can also be used as a MPPT Controller is built in.

Benefits:

• Arrive at camp with your van or motorhome's house batteries topped up.
• Some 4WD guys who free camp simply use it to charge a deep cycle battery in the back of their 4WD, as it is ideal for topping the power up for an energy hungry 12V esky style fridge box.
•  It can also be used to top up a trailer boat’s electric trolling motor batteries.

Multiple source charging for DC systems - from either solar or your vehicle's alternator (via battery).

Idelal for 4WD's caravans, motorhomes and boats.

The Enerdrive ePOWER DC2DC+ Battery Charger is a fully automatic multistage, multi input battery charger with the ability to charge from either an alternator linked to a battery; or via solar power with the DC2DC40+'s  the in built  (MPPT) Solar Controller.

Suits: Gel, flooded, AGM, Lithium  or Program batteries.

Dimensions:  242 (Hight)  x172 (wide) x74mm (deep) Weight: 1.85kg 

The Enerdrive ePOWER DC2DC+ Battery Charger is a fully automatic multistage, multi input battery charger with the ability to charge from either an alternator linked to a battery; or via solar power with the in built Maximum Power Point Tracking (MPPT) Solar Controller. With two inputs available, the main/house battery will be charged from either the engine while underway, or via the solar panels when stationary.
The process to choose either engine or solar is fully automatic and both functions are controlled from within the unit itself without the need for external relays.

Features:

• Two totally independent DC Inputs for both engine and solar regulation charging one house battery bank output
• DC M6 screw terminals that will allow for large battery cable connection between all sources
• A dedicated Maximum Power Point (MPPT) solar regulator
• The same battery algorithms as included in our AC mains ePOWER battery charger. GEL, AGM, Flooded, Lithium and the ability to create  a full custom profile
• Vehicle input allows for either 12 or 24v and a maximum solar input of 45V/800W
• 40A output up to 40+°C with thermo controlled fan cooling
• Fully programmable LCD display to show which source is charging the battery along with charger status, voltage and amperage
• Temperature sensor included in charger for more accurate battery charging

The Solar Input on the DC2DC+ unit has a maximum rated INPUT current of 30amps. This means it is optimised for using higher voltage ‘grid’ type modules for best output performance. 
The maximum achievable output using standard 20Voc solar modules will be approx 35amps @ 14.4Vdc
Maximum achievable output on the DC2DC+ unit when using 43Voc Solar Panels will be the approx 47amps.

Multi Stage Charging Process: Stage 1 - Bulk or Boost, Stage 2 -Absorption charge, Stage 3 Float 

The ePOWER DC2DC+ Battery Charger is a fully automatic, set and forget charger.
It is designed to quickly and accurately recharge your deep cycle batteries utilising charger algorithms that help to maximise the life of your specialised deep cycle batteries.

With the input of multiple sources, you can be assured of charging your batteries whenever underway, or,  when the sun is shining on your solar panels.
