I know many are looking for away to add a park feature to the SunTura. I was planning on adding a simple toggle switch to turn On/Off the SunTura for when I do maintenance on my tracker. However while playing with ideas for parking I figured a simple toggle switch would work too. This will require some soldering skills but luckily the circuit board isn't to difficult to work with. Things you'll need: 1: A fine tipped soldering tool 2: Electrical solder and flux (not plumbers stuff) 3: Philips screw driver to open/close case 4:One toggle or rocker type switch 5: One mini relay 12 volt if your powering with 12 volt, 24 volt if your powering with 24 volts 6: 2 short pieces of wire 1 Black and 1 red so you don't mix up + and -, 1 foot of each will be plenty Gauge should be no bigger then that which feeds the SunTura (14 I believe) you can use smaller gauge for wiring to circuit board 7: Wire snips 8: Drill and bit sized to allow switch to fasten to control box. 6: Electrical tape , glue or both Total cost: under $25 , cheaper if using 12 volt relay.
