Overview
Featuring a Maximum Power Point Tracking (MPPT) solar regulator, the BCDC1240D Classic 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 perfect for pairing with a Lithium Battery. 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 typically used for lead acid battery banks over 200Ah and lithium batteries over 100Ah. Check the manufacturer’s data for your battery and ensure that the ‘Continuous Current Rating’ of the charger does not exceed the manufacturer’s recommended maximum charging current.
