Photovoltaic controller up to 180W /12V power modules

General Description:

SPC07-IP is a charge controller for PV applications. It is able to manage the
charge of 12.Vdc nominal voltage Pb batteries and two different DC loads of
max 7A total current, with eleven different configurations. "Light sensor"
detection is made by the module. The charge algorithm is PWM - Mosfet with
voltage compensated in temperature: through an external NTC sensor
(optional) or through the sensor inside the circuit which supply also a
protection against over-temperature. SPC07-IP 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 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.
- External NTC temperature sensor

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; do not insert a further blocking diode:
you would annul the "light sensor" detection. 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.
We advise the external NTC temperature sensor (optional) in case of big differences in temperature between
controller and batteries. Connect to the proper connector the external NTC temperature sensor and, if
requested by the chosen configuration, connect also either the infrared sensor (PX01) or the switch for
remote habilitation. 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 (ser the
following page). To simulate SUNSET we advise to cover carefully the PV module using a quite thick
