Photovoltaic controller up to 180W /12V power modules

General Description:

SPC07-IP Lifep4 is a charge controller for PV applications. It is able to manage
the charge of 12.8V nominal voltage LiFePO4 batteries and two different DC
loads of max 7A total current, with eleven different configurations. The
charge algorithm is PWM - Mosfet with 14.1V charge voltage.
SPC07-IP Lifepo4 includes a blocking diode to avoid the discharge of battery
through the PV modules; at the same time a Low-Battery control save the
battery from deep discharges caused by the load consumption. A bi-coloured
LED shows eventual status of error (red colour) and presence of panel current
(green colour), two yellow LEDS show the activation of each load. SPC07-IP
Lifepo4 can simultaneously power two independent 12V DC loads with total
current limited to max 7Amp, if only one load is used the maximum current of
7A can be supplied to this one. The circuit is placed inside a IP56 compact box
which has already got cable glands to have an easy wiring. The controller is
equipped with a connection board with cables up to 2,5mmq for battery and
panel, while the connection of sensors can be made using cables of 1,5mmq
max section.

Installation procedure:
Avoid direct exposure to sunrays (caution: over-heating), avoid water and humid environments. PAY
ATTENTION TO POLARITIES AND AVOID SHORT-CIRCUITS; they are destructive and cancel warranty. Connect
the battery cables only after having connected all the others. Put the battery in the chosen place, connecting
in the proper way the cables and reducing the distance from the charge controller more that you can. On
starting the LED must effect a green and red lightning to indicate a correct power on. To test if the installation
of the controller has been made in the right way it is necessary to verify that at sunset the load switches on
according to the configuration that has been set by the Switches (see the following page). To simulate SUNSET
we advise to cover carefully the PV module using a quite thick cardboard; it could be necessary to cover even
the rear side of the PV module. We saw that if you connect to the controller SPC07-IP some kind of PV
modules the controller is not able to detect the night. If you are in such conditions, please contact Western
CO. Service Center.
