geared motors that are going to be connected to the SunTura Solar Tracker Electronics and make sure each
motor used does not exceed the 14 amp limit.
3.2.1 Electronics Box Installation
The Electronic Box has a 20 amp fuse on the circuit board located on its inside. There is also one additional
spare fuse. The fuse protects the SunTura Solar Tracker Electronics from a short circuit. If you accidentally
short circuit the electronics, simply replace the blown fuse with the spare fuse. Do NOT bypass the fuse.
Additionally, there are four buttons on the top of the Electronics Box which allow one to manually move the
linear actuators in the north, south, east and west directions. See Figure 2 below.
Figure 2: Electronics Box manual controls and fuse locations.
WARNING: Do NOT connect the SunTura Solar Tracker Electronics to the power supply until you
have completely finished the installation process and all people are safely away from the solar
tracker’s range of motion!
The red and black wires coming out of the Electronics Box are the power supply wires. These wires need to
be connected to a 12 or 24 volt DC power supply. Some good examples of power supplies are a 12 volt
battery, a 24 volt battery or a 12/24 VDC power supply that plugs into an AC wall outlet. The DC power
supply must also be able to supply enough current (amps) to power the motors you choose to use for
tracking.
Additionally, the DC power supply can NEVER exceed 30 volts DC or the SunTura Solar
Tracker electronics will be permanently destroyed. Even if the voltages exceeds 30 VDC for only just an
instant, the electronics will be permanently destroyed! Windy Nation Inc. recommends a car sized 12 volt
battery to power the SunTura Solar Tracker Electronics. The red wire coming out of the Electronics Box
connects to the positive output of the DC power supply. The black wire coming out of the Electronics Box
connects to the negative output of the DC power supply. See Figure 3 below.
