SOLARSAN-GPS V17 (WiFi MQTT)
A complex for tracking the sun based on the calculation of the
data received from the GPS receiver. This system consists of a
basic module SOLARSAN-GPS that can work independently
and SOLARSAN-SLAVE working only as an executive device.
Using SOLARSAN-GPS, you can target solar concentrators,
collectors or panels at right angles to sunlight. Control is carried
out with the help of actuators or rotary actuators in two planes
and has an accuracy of one degree. The module has an input to
connect an "anemometer" to protect against strong wind, the
input of the "hail and snow sensor" and the input of the "photo
sensor" for the sleep mode with low solar activity. Built-in WiFi
module allows you to configure the tracker through the WEB
page over a local network or through an access point. The built-
in MQTT broker allows you to manage and receive data via the Internet network around the world. Power supply from
12V to 30V (and version HV with power from 12V to 55V). Protection by current. Short circuit protection. Built-in
radio modem 433.92 (315.00) MHz with a capacity of 100 mW for data transmission in a radius of up to 100 meters to
the SOLARSAN-SLAVE modules. Works both in one and two axes. The IP66 enclosure allows you to install a solar
tracker under the open sky.
The requirement for a mechanical part
•
The axis of rotation must
not be tilted. This adds
declination and in extreme
positions from 180
degrees (south) there will
be a large error.
•
For the correct operation
of the control module, it is
necessary to correctly install the drives in such a way
that the conditions are met. The movement along the
azimuth should lie in the range from 1 to 359 degrees.
•
The initial angle in height should lie in the limit from 0
to 20 degrees. Where 0 is when the panel is
perpendicular to the ground.
•
The final angle in height should always be 90 degrees. This is the position where the solar panels are parallel to
the ground.
•
The movement must not be limited mechanically, but by limit switches installed in the gearbox or on the
moving parts of the drives.
•
There must be no obstacles in the entire range of movement.
•
The feedback sensor installed in the gearbox must close the circuit. This can be a reed switch or hall sensor
SS449A.
•
The maximum number of feedback pulses should not exceed the value set by GR (see Configuration).
•
The power wires of the drives must not clamp the moving parts.
•
The result depends on the correct setting especially for
parabolic concentrators.
