DC-DC Charger with MPPT
Streamline your dual battery system using a 12V or 24V DC-DC charger with solar input
Streamline Your Power with a DC to DC Charger with Solar Input
When touring in a 4WD, caravan, RV, or boat, managing your auxiliary battery power is critical for running fridges, lighting, and other essential electronics. A combined DC to DC charger with MPPT offers the ultimate all-in-one solution for mobile power systems. Instead of wiring a separate battery isolator and a standalone solar regulator, these dual-input chargers seamlessly manage power from both your vehicle's alternator and your off-grid solar panels.
Highly Efficient Dual Battery Charging
Whether you are upgrading a 4WD canopy or outfitting a commercial truck, a DC DC charger with solar input ensures your auxiliary power system receives the correct charging profile while on the move. When driving, the unit draws power from the alternator to rapidly replenish your deep cycle batteries. Once you set up camp and turn off the ignition, the integrated Maximum Power Point Tracking (MPPT) solar charge controller automatically takes over, harvesting energy from your solar array.
We carry trusted models like the Enerdrive ePower range, offering options such as the robust 40 amp DC to DC charger with solar input and versatile 24V variants, designed to handle extreme environments and demanding power loads.
Why Choose a Combined DC-DC MPPT Unit?
Upgrading to a single unified charger simplifies your wiring and optimises limited installation space in your canopy, tiny home, or marine vessel.
- Space-saving design: Consolidates your vehicle alternator charging and off-grid solar panel regulation into one robust unit.
- Smart priority switching: Automatically prioritises solar power when available to reduce alternator load, seamlessly switching sources based on driving conditions.
- Tailored charging profiles: Fully programmable for various battery chemistries, ensuring safe and highly efficient charging for your 12V or 24V system.
- High-output options: Select from powerful models, including 30A, 40A, and up to 50 amp DC to DC charger with MPPT configurations to suit heavy electrical setups.
Expand Your Off-Grid Setup
To maximise the performance of your dual-input charger, it is essential to pair it with high-quality components. If you are starting a new build, explore our extensive range of Off Grid Solar Panels to find the perfect roof-mounted or portable solution. Ensure your power storage matches your charging capacity by integrating robust 12V Deep Cycle Batteries or 24V Deep Cycle Batteries. For safe installation and optimal performance, remember to pick up the necessary DC-DC Charger Accessories.
Frequently Asked Questions
How does a DC to DC charger with solar input work?
These units feature two independent inputs. While driving, they boost or step down the alternator voltage to correctly charge your auxiliary battery. When the engine is off, the built-in MPPT controller captures power from your solar panels, ensuring uninterrupted charging without requiring manual switching.
Can I use a 24V input to charge a 12V battery?
Yes, many advanced DC DC charge controllers support variable inputs. Depending on the specific model, they can handle a 24V or 12V alternator input to charge a 12V or 24V battery bank, acting as both a charger and a voltage converter.
What size charger do I need for my setup?
Your charger size should align with your battery bank capacity and alternator limits. A 40 amp or 50 amp DC to DC charger with MPPT is ideal for large lithium battery banks, while a 30A unit is highly efficient for smaller auxiliary setups in standard 4WDs or camper trailers.
