1st step: Connect loads
Connect the load cable with the correct polarity of the right-hand side pair of terminals on the solar
charge controller (with the lamp symbol). To avoid the presence of any tension on the cable/wires, please
connect these first to the load before connecting them to the charge controller.
2nd step: Connect the battery
Connect the battery cables observing the correct polarity to the center pair of terminals (make sure you
identify the battery marking/symbol on the controller casing!) of the PV charge controller. Pay greatest
attention to polarity. Never, ever invert the plus+ and minus- poles).
1)Should your system be nominal 12 Vdc, make sure the battery voltage is between the
10
.0 and 15.
0
Vdc
voltage range;
2)
for 24 Vdc nominal voltage, the battery voltage should be within the 20.0 to 3
0
.0 Vdc range
;
3)for
36
Vdc nominal voltage, the battery voltage should be within the
31.0 to 42.0Vdc;
4)for
48
Vdc nominal voltage, the battery voltage should be within the
42.0 to 62.0Vdc.
If the polarity is correct, the LCD on the controller will begin to display those.
3rd step: Connect the solar module
When connecting the PV-Module make sure to cover it from incident sun light. Double check the PV-
Module will not exceed the maximum permissible input current of the Charge Controller (please refer to
the section Technical Data). Connect the solar module connection cable to the correct polarity of the left
pair of terminals on the solar charge controller (with the solar module symbol).
4th step: Final work
Tighten all cables connected to the controller and remove all the remains around the controller (leaving a
void of minimum 15 cm).
5.5 Grounding
Be
aware
that
the
positive
terminals
of
controller
are
interconnected
and
therefore
bear
the
same
electrical
potential
.
If
any
grounding
is
required
,
always
do
this
on
the
positive
wires
/
terminals.
CAUTION: 1
.
If
no
temperature
sensor
is
connected
to
the
controller
,
the
battery
temperature
value
will
display
the
internal
temperature
.
2
.
If
a
power
inverter
is
used
the
system
,
it should be connected to the battery via a DC
relay
.
Do not
connect
it
to
the
controller
'
s
load
terminals.
