The REDARC BCDC1240D In-vehicle Battery Charger is the next generation in REDARC's DC to DC charging technology, with additional features that make it the most advanced dual battery charger on the market.
 
Featuring a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1240D will charge from both solar and the alternator simultaneously. With built-in 'Green Power Priority' it will select solar charging first, meaning less load on the alternator.
 
Suitable for 12 or 24-volt vehicle systems, the unit will also work with either standard or variable/smart alternators.
 
The BCDC1240D also comes with patented charging profiles, including a lithium charging profile. The 'Dual' input range will continue to charge all other types of batteries including AGM, GEL, standard lead acid and calcium. 
 
As a guide, the BCDC1240D is used for battery bank sizes over 200AH. For smaller batteries of 75-200AH REDARC recommends the BCDC1225D.
