4-2 Specification Solar Charger Controller
NOTES:
For use with solar panels only
Connector Installation.
IMPORTANT: Connect Battery FIRST
Wire size Max. current 4A /sq.mm.
Keep wiring lengths to a minimum to reduce voltage drop.
Connect battery wires to the controller first. Ensure correct polarity of terminals.
(Note. 1)
Connect the solar panel to the quick connector and expose to sunlight. The PV LED
will illuminate, indicating that the connection is correct and battery is charging.
