Principle of operation
SOLARSAN informs you at power-up by two beeps about power supply. After that, the motor turns on the azimuth (X
axis) counterclockwise at dawn. If the motor stopped earlier, it disappears or there is no feedback signal. The same
procedure is repeated for the axis height (Y axis), the motor will start to set the panel perpendicular to the ground. This
is the starting position. After determining the data of the satellites, as indicated by the flashing LED, SOLARSAN will
set the panel perpendicular to the sun's rays. With each change in the design position of the sun by one degree, the
panels will be pushed to achieve maximum positioning accuracy. This is especially important for parabolic
concentrators. Every minute, data on all calculations and positions are output to the port and transmitted by the
transmitter for SOLARSAN-SLAVE.
At the end of the day, when the sun is over the horizon and no protection is activated by the wind or hail sensor, a
reboot will occur and the panels will be set to the initial position. This is done to prevent snow on the warm panels.
In the event that a wind sensor is triggered at night, the panels will move to a position parallel to the ground and remain
in this position until dawn.
Setting the current protection threshold
The module SOLARSAN-GPS provides several types of protection. In the actuators there are limit switches, the
module always knows in which position the drive is located and will not give the task to move beyond the value, and
there are also two types of current protection - a fuse and an electronic current sensor. The current sensor threshold can
be set with the trimmer resistor "MOTOR i". For convenience of adjustment, for 10% before shutdown, the control
module will warn the buzzer. The current threshold is set at the time of travel and is effective for both drives. Therefore,
I recommend using drives of the same power.
Setting the wind speed Input 90 "
To determine the wind speed, you can use any factory anemometer or self-made
anemometer that produces a voltage proportional to the wind speed. The threshold
can be specified through the configuration. This input is used to determine the excess
of the set wind threshold. The average wind speed in three minutes should not exceed
the set value. Otherwise, the controller will set the Y axis drive to a position of 90
"(parallel to the ground) which can save, for example, a large solar panel from being
destroyed. To return to
the working position, the
average wind speed in three minutes should be five times
less than the set one. To calibrate the wind threshold, you
need a calibrated anemometer and a fan with speed control.
Set the fan on the anemometer the required wind speed,
after which, read the current configuration value.
Parameter WI- "" means the instantaneous wind speed. The
parameter WU- «indicates the threshold value of wind
speed. The values are set from 11-255 and the input value
is from 0-255. Where 0 is 0 volts, and 255 is 5 volts. If, for
example, you set 10m / s, then with an average arithmetic
value of the wind in three minutes exceeding this value, the
Y axis will take the value of 90 ", and to return to operating
mode, the arithmetic mean wind speed in 3 minutes should
be below 2m / s.
WIND Input
This input is provided for installing the tracker parallel to
the ground. While this input is closed on the GND tracker,
it will be in wind protection mode. When the input is opened, the tracker will be set according to the calculated angle.
Above the WIND input, there is a HAIL input priority and MQTT control.
Connecting the hail sensor
The hail sensor is mounted directly on a glass or plastic surface with a double-sided adhesive tape or glue. To connect,
you need three wires. Power sensor hail 5 volts. The input is "logical" if you close it to "GND", then the Y axis will take
0 "(perpendicular to the ground). The input of the "hail sensor" takes precedence over the "wind sensor".
Master-Slave
The SOLARSAN-GPS module is the "Master" radio transmitter installed in it, which provides communication with the
SOLARSAN-SLAVE modules. The communication radius depends on the transmitter model. By default, the range is
about 100 meters, but you can increase it to 1000 meters by installing a more powerful transmitter. SOLARSAN-
SLAVE does not have sensors for hail, snow, light, wind and GPS module. Its task is to take a ready signal and repeat
