The SIS Sensor is a means of verifying the correct operation of the PV system which is
associated to it, promptly reporting any problems.
The SIS sensor must necessarily operate in conjunction with an In-house Display and a Radio
Transmitter (IntellyGreenPV basic kit).
All information submitted subsequently refers to when the In-house Display and the Radio
Transmitter are already installed and working properly; if not, first install these devices.
If there are obstacles between the SIS Sensor and the In-house Display, or there's too much
distance between them so as not to ensure effective communication, the use of the Radio
Repeater is necessary. Please note the Radio Transmitter is also a Repeater by default.
You can connect only a single SIS Sensor to a single In-house Display.
The device consists of:
no. 1 SIS Sensor
no. 1 Mounting Bracket
no. 1 Temperature Probe.
Caution:
For the proper functioning of the SIS Sensor, the In-house Display's firmware version must
be1044 or later. If the In-house Display's firmware version is older (1043 or earlier) it must be
updated.
The updated firmware for the In-house Display is on the CD-ROM included with the kit. If you
have problems finding it, contact 4-noks. For the update, refer to the In-house Display user
manual.
Presentation of the ZED-SIS-PV-M (SIS Sensor) device
The In-house Display notifies the presence of an SIS Sensor, lighting a specific icon on the main page, on bottom left.
From the main page of the In-house Display, pressing the button underneath the SIS icon (first button from the left)
you can access a menu to view the SIS Sensor's data.
1) First line: Indication of the radio signal
The printed icon refers to the value of the RSSI (Radio Signal Strength Indicator) value referred to the radio messages
received by the SIS Sensor.
4 bars --> high reception (signal stronger than -70dBm)
3 bars -> medium-high reception (signal between -70 and -80 dBm)
2 bars -> medium-high reception (signal between -80 and -90 dBm)
1 bar -> low reception (signal weaker than -90 dBm)
x -> no signal from the transmitter for more than 6 minutes
2) First line: Indication of Battery:
Full Battery: Voltage higher than 3.1 V
Half Battery: Voltage between 2.9 and 3.1 V
Battery Drain: Voltage lower than 2.9 V
3) Power: value of the power transmitted by the SIS Sensor (expressed in kW with two significant digits). If you have
not done the calibration, the displayed number has no meaning and therefore it appears without any unit of
measurement.
4) Today Energy: Energy detected by the SIS Sensor on the current day. If you have not done the calibration, the
displayed number has no meaning and therefore it appears without any unit of measurement.
5) Power Efficiency (first line):
The ratio between the energy detected by the Radio Transmitter (Pulse-Counting Sensor) and the energy detected by
the SIS Sensor in the last hour of operation (hourly average power ratio).
This value is used to generate the Efficiency Alarm.
If you have not done the calibration or if there are no data because the In-house Display has been on for less than one
hour, two dashes "--" are displayed).
6) Energy Efficiency (second line):
The ratio between the energy detected by the radio transmitter (Pulse-Counting Sensor) and the energy detected by
the SIS Sensor from midnight of the current day (daily power ratio).
If you have not done the calibration or if there are no data because the In-house Display has been on for less than one
hour, two dashes "--" are displayed)
7) Brightness:
Instant value of the brightness detected by the SIS Sensor.
This value is expressed without unit of measurement; although the sensor is preset by the manufacturer, this value is
to be considered as purely indicative.
8) Temperature:
Instant value of the temperature detected by the SIS Sensor (value expressed in degrees Celsius).
You can associate the SIS sensor to the In-house Display before or after the installation. For your convenience, it is
preferable to perform the association before installing the sensor.
To start the association, act on the In-house Display and start the procedure to "Open Network" (Menu/Radio
Management/ Open Radio Network).
With the "Open Network" stimulate the SIS sensor placing the label "Magnetic Switch" near it.
After a few seconds, the device should become part of the In-house Display network; in that case, the Sensor SIS LED
will flash quickly and the message "Found new sensor" will appear on the In-house Display (note: in some situations, the
message may not appear).
When the procedure is over, press the OK button on the In-house Display to close the network. The "Open Network"
status lasts for a maximum of 4 minutes, after which the network is automatically closed.
If after 20 seconds of stimulation the SIS sensor is still not networked, repeat the procedure; in case of repeated failure it
is necessary to disconnect the SIS sensor that could be mistakenly associated with another radio network. After the
disconnection, repeat the procedure of association.
The SIS sensor is not an absolute measuring instrument.
The measurement of the solar radiation in an absolute and reliable way requires different
sensors and is beyond the purpose of the SIS sensor.
The SIS sensor is a relative measuring instrument; its operation is subject to calibration.
With the calibration, the In-house Display relates the measurement of the energy coming from
the SIS sensor with the measurement of the energy coming from the photovoltaic meter.
This makes it possible to separate the calculation of the efficiency from a wide range of factors
including type and number of solar panels, their temperature, the presence of shadows and other
disturbances.
The log related to the calibration is stored in the non-volatile memory of the In-house Display and
is then used to correlate the SIS sensor reading with the values obtained at the time of
calibration.
Performing the calibration when the system is at its best makes it possible for the In-house
Display to detect any subsequent deviation, showing the user the possible lowering of the
system efficiency.
After the calibration, the system performance is calculated every 15 minutes, based on the
average values per hour of operation.
LED
The SIS Sensor LED lights up briefly when the device performs an acquisition (every 10 or 30
seconds) or when it sends a radio message to the In-house Display (every 90 or 270 seconds).
When the device is not associated, the LED is turned on for the duration of the association process;
if the association process is completed successfully, the LED flashes quickly.
Magnetic Switch
Placing a magnet near the "Magnetic Switch" label, the SIS sensor makes a transmission to the In-
house Display.
When the device is not associated, the magnet causes the activation of the association process.
Placing the magnet near the "Magnetic Switch" label for more than 10 seconds causes the
disconnection of the sensor from the radio network.
