Standalone Solar Tracker Controller MICRO-D positioner for PMDC motors<\/strong><\/p>\n

The MICRO-D Solar Tracker Controller is designed to operate one dual-axis, or two single-axes solar trackers with PMDC motors. It is ideally suited for sites with a single or limited number of solar trackers. The MICRO-D have USB connectivity to manage via PC directly and RS485 communication for wired distance monitoring via RS485 to USB converter, but with help of wire to\u00a0 wireless converters you can monitor and manage also distantly. Also, with additional connecting on to SIGMA solar server the remote monitoring and management through internet is possible. Simple and fast installation, high reliability.<\/p>\n

Features<\/strong><\/p>\n

\n
Supports dual-axis, up to two single-axis, roll-and-tilt trackers with PMDC motors.<\/div>\n
Calculated solar position using astronomical algorithms.<\/div>\n
Automatic detection of storm with parameterized peak wind speed threshold with wind sensor.<\/div>\n
Parameterized fixed positions for Snow, Storm or Clean positions.<\/div>\n
Alarming at electro-mechanical failure.<\/div>\n
Manual control of motors.<\/div>\n
Power fail detection.<\/div>\n
Tracker position feedback through quadrature encoder without any external sensor or with external inclinometer.<\/div>\n
Optional fine tuning via optic sensor.<\/div>\n
Optional moving out of sun for certain angle when thermal collectors overheated.<\/div>\n
Optional monitoring of solar irradiation and\/or temperature probes.<\/div>\n
Tracker mode for following the sun or Heliostat mode with supported three different target positions through the three different time periods per day.<\/div>\n
Parameterized geographic location, tracker geometries (many), heliostats, supported slewing drives and linear actuators.<\/div>\n
Monitoring and managing of solar tracker via free program Helios analytics.<\/div>\n
Integrated support for Android app via USB.<\/div>\n

Description<\/strong>
\nOne Controller – Many Applications<\/strong> \u2013 The MICRO-D stand-alone solar tracker controller can be used in a wide range of solar tracker applications through an extensive set of parameters. It is being used in new applications, but can also be used in the retrofit market.
\nDual-Axis Trackers<\/strong> \u2013 One MICRO-D positioning controller is capable of managing a single dual-axis tracker through the two motor channels with PMDC motors. The tracker can either be of the traditional azimuth \/ elevation type (cartesian coordinate system), roll (east-to-west) and elevation type (polar coordinate system).
\nSingle-Axis Trackers<\/strong> \u2013 One MICRO-D positioning controller is capable of managing up to two single-axis solar trackers through the two integrated motor channels. The tracker(s) can either rotate around the North\/South, East\/West or Polar Axis.
\nCommunication<\/strong> \u2013 Using the USB port or RS485 the MICRO-D positioning controller through the Android or PC app Helios analytics allow full control, setup, monitoring, and software updates.
\nLocal Control<\/strong> \u2013 Basic local tracker control can be done through onboard push-buttons, or more extensively through the Android app Helios analytics which is used to define controller parameters and\/or monitoring.<\/p>\n
