Featuring a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1225D will charge from both solar and the alternator simultaneously. And, 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 BCDC1225D features the same patented charging profiles as it’s predecessor along with a new lithium charging profile making the unit suitable for charging AGM, Gel, Standard Lead Acid, Calcium and LiFePO4 batteries. For most applications, the BCDC1225D is suitable for battery bank sizes of 75-200AH. For higher capacity needs of over 200AH, REDARC recommends the BCDC1240D.
