b) Installation Way
SDI-P Series controller should be perpendicular installation. To ensure
that the thermal resistance of the wind through the radiator is minimum, the
controller external upper and lower ends should at least keep 15cm space
for airiness
c) Battery Connection
Please select the connect cable diameter according to the controller
input/output maximum current value. and it is better select the multi-strand
and thicker cable. the wiring length as short as possible to avoid too long
or too thin. in order to reduce the cable loss and cable temperature.
Firstly, connect the battery, after correctly connection. the LCD display
will light up within 2 seconds. and enter self-test, will display the automatic
identification system voltage value. If the voltage display does not match
with the actual system voltage. Please enter manually set state to adjust
it.Typically,as long as the battery voltage is in the range shown in the
following table, the controller can correctly recognize the system voltage
without manually setting.
12V system
DC 7V-17V
24V system
DC 18V-28V
36V system
DC 32V-40V
48V system
DC 42V-60V
Noted.
: please use insulating screw driver when wiring, to ensure the
connection is secure After battery connection, the user should set up the battery
type and charge way. SDI series with default battery type at lead-acid battery,
three
–stage charging.
d) Battery temperature detection cable Connection
Battery temperature detection, Mainly in order to compensate for the battery
temperature characteristics of the battery at different temperature, normal is -
5mV/
℃
/2V, in the case of less demanding system can not be installed. A
standard temperature Sensor(DS18B20) for SDI-P series.
e) Solar Panel Connection
Make sure the PV voltage in the correct range before wiring , to avoid
damage to the controller. After connecting the PV, LCD screen will display
the status of PV solar panel.
