SunArx C-6 Control Board

There are various ways to control a solar tracker. Timer-based digital control has become very common for large PV tracking systems, and we have chosen that approach for the C-6.  The control board has an onboard digital clock which is set to local solar time - that is, noon is when the sun is directly south.  After setting the time, simply set which of the 6 channels are being used, and you're done.  Fine adjustment to the time can be done at any time.  There are also some additional features to make the installer and owner's life easier:

1. Intuitive clock interface makes it easy to see if trackers are working properly.

2. One C-6 controls up to 6 T-21 trackers, minimizing costs.

3. Standard C-6 package includes AC power supply to generate 24VDC and weatherproof enclosure.  Other power supply options are available if AC power is unavailable.

4. Maintenance mode allows placing any or all trackers in center position for service.

5. Full set of error indications on the display for diagnosing any problems.

6. Reverse polarity protected.

7.  Operating Range -25C to +85C.  Self consumption 70mA, 50Wh per day (single tracker).
