WARNING
ISC3020 can work with input voltage up to 45 Vdc maximum; when installing at this voltage, particularly
with regard to module open circuit voltage (Voc), the entire solar energy system must be installed with
protection class II. Cover solar modules during installation and use only insulated tools.
CONNECTING / DIS-CONECTING SYSTEM SEQUENCE
Connect the wires in the sequence from 1 to 6 according the above diagram; when
Disconnect the wires in the REVERSE sequence from 6 to 1 according the above diagram.
Use with 12V or 24V battery bank, (controller will detect voltage of battery automatically).
Never exceed the nominal ratings (see below technical data for reference).
Suggested cable length, 10m solar panel connection cable/2m battery connection cable/5m load
connection cable.
