This dual input charger from Australian power management specialists, REDARC, combines DC-DC charging and solar charging for your 12V leisure battery into one rugged, compact unit. Featuring REDARC's next generation of in-vehicle charging technology, it is the most advanced dual battery charger on the the market and has been designed to withstand the harsh environment of the Australian outback. Rigorous testing ensures that it will perform under extreme conditions where moisture, dust and vibration are present, meaning it won't let you down.

Suitable for use with standard or 'smart' Euro 5 / 6 / 6+ alternators, the BCDC1240D combines a 40A DC-DC (battery-to-battery) charger together with a 600W MPPT solar charge controller, giving you the ability to charge either from your alternator, your solar panels, or both. It utilises Green Power Priority, so the charger will always use the maximum amount of solar power available, with the remainder of the rated output being provided by the vehicle's alternator.  The charger will isolate the leisure (auxiliary) battery from the vehicle starting battery when no charging input is present to prevent the vehicle battery being discharged by the domestic circuits.

The BCDC1240D supports all battery types (wet and sealed lead-acid, AGM, Gel, calcium and Lithium) and uses multi-stage charging technology to ensure 100% full charging, maximising the performance and life of your batteries. It is straightforward to install with a very simple setup and has a wide vehicle input voltage range (9-32V DC), allowing you to charge a 12V battery from either a 12V or 24V alternator input. This makes is suitable for use in vans and small motorhomes as well as in larger motorhomes, horseboxes and  lorries.

Important - only to be used with solar panels that have an Open-Circuit Voltage (Voc) of 32V or less.  Greater voltages may damage the unit and will void the warranty.

Recommended for battery capacities of 200Ah and greater.
