Is connected between the 12 V/DC solar panel and 1 or 2 batteries to prevent the batteries from overcharging. If 2 batteries are connected, they are charged separately. The battery with the lowest charging voltage always receives more charging current. With LED indicators + high charging capacity: max. 2 x 8 A or 1 x 16 A.

Technical data:
Input voltage: Solar panels 15 - 30 V/DC open-circuit voltage, 12 V/DC nominal voltage
Max. Charging current: 16 A total (2 batteries max. 8 A each or 1 battery connected in parallel to both outputs
connected to both outputs up to 16 A)
Connections: 1 or 2 batteries 12 V. If only 1 battery is connected, then both
outputs (1 + 2) are connected in parallel (simultaneously) to the battery
Displays: one "battery charging" display per battery, 1 display: "all batteries full"
Cooling: For currents > 4 A, the module must be placed with the metal underside on a heat sink
with a surface area of > 300 square centimeters.
Fuse: A back-up fuse F16 A is required (not included)
Switch-on voltage: Battery approx. < 13.4 V/DC (± 5%)
Switch-off voltage: "Battery full" approx. 14.4 V/DC (± 5%)
Intrinsic current consumption (taken from the battery): < 2 mA
Resistant to reverse current (no additional diode required)
Dimensions: approx. 87 x 60 x 33 mm
