1ST STEP: CONNECT THE BATTERY
-
Label the battery connection cables as a plus cable (A+)
and a minus cable (A–).
-
Lay the battery cables in parallel between the solar
charge controller and the battery.
-
Connect the battery connection cable with the correct polarity to the
middle pair of terminals on the solar charge controller (with the bat-
tery symbol).
-
Remove any external 40A fuse in battery connection cable A+.
-
Connect battery connection cable A+ with 40A fuse to the Positive
pole of the battery.
-
Connect battery connection cable A– to the Negative pole of the bat-
tery.
-
Replace the external fuse in the battery connection cable A+.
-
If the connection polarity is correct, the info LED illuminates green.
2ND STEP: CONNECT THE SOLAR MODULE
-
Ensure that the solar module is protected from incident
light.
-
Ensure that the solar module does not exceed the
maximum permissible input current.
-
Label the solar module connection cables as a plus cable (M+) and a
minus cable (M–).
-
Lay both solar module connection cables in parallel between the solar
module and the solar charge controller.
-
First connect the M+ solar module connection cable to the correct
pole of the left pair of terminals on the solar charge controller (with
the solar module symbol), then connect the M– cable.
-
Remove the covering from the solar module.
3RD STEP: CONNECT LOADS
Notes:
-
Deep Discharge Protection (also called Low Voltage
Disconnect or LVD) is only provided for loads < 20A that
are connected to the Load Terminals (5).
-
Critical loads like emergency lights, radios, etc. that require un-inter-
rupted power source are connected directly to the battery through
fuse – close to the battery to protect battery cables against short
circuit.
-
Loads drawing > 20A should be connected directly to the battery,
preferably through separate Low Voltage Disconnect (LVD). Appropri-
ate fuse should be used close to the battery to protect battery cables
against short circuit.
-
Other loads drawing < 20A should be connected to the Load Terminals
(5) as follows:
-
Label the load connection cables as a plus cable (L+) and a minus
cable (L–).
-
Lay the load connection cables in parallel between the solar
charge controller and the load
