1.0 GENERAL INFORMATION
Thank you for selecting the SunLight™ solar lighting controller.
The SunLight is an advanced design using a microcontroller for
digital accuracy and fully automatic operation. The PWM battery charging has been optimized for longer battery life.
Many specifications of the SunLight are unique. Although the
SunLight is very simple to use, please take the time to read this
operator’s manual and become familiar with the controller. This
2
will help you to make full use of the many advantages the
SunLight can provide to your solar lighting system.
2.0 IMPORTANT SAFETY INSTRUCTIONS
• SAVE THESE INSTRUCTIONS—This manual contains important
instructions that should be followed during installation and maintenance of the SunLight controller.
• WARNING—Be very careful when working with batteries. Lead
acid batteries can generate explosive gases, and short circuits
can draw thousands of amps from the battery. Read all instructions provided with the battery.
• Do not exceed the voltage or current ratings of the controller.
Use only with a 12 volt or 24 volt battery.
•
DO NOT
short circuit the PV array or load while connected to
the controller. This will
DAMAGE
the controller.
• The controller should be protected from direct sunlight. Ensure
adequate space for air flow around the controller.
• Pressure terminal connectors are not required. Use only copper
wire with minimum 75˚C insulation rating and between 10 AWG
(5.2 mm
2
) and 14 AWG (2.1 mm2) gage.
• The negative system conductor should be properly grounded.
Grounding should comply with local codes.
3.0 QUICK START INSTRUCTIONS
This section provides a brief overview of how to get started using
the SunLight controller. However, please review the entire manual
to ensure best performance and years of trouble-free service.
1. Mount the SunLight to a vertical surface. Allow space above and
below the controller for air flow.
2. Make sure the PV and load currents will not exceed the ratings
of the SunLight model being installed.
3. The 6 system connections to the SunLight terminals
are numbered on the label. It is recommended that the
connections be made in order from 1 to 6.
4. Connect the
BATTERY
first. Use care that bare wires do not
touch the metal case of the controller.
5. Connect the
SOLAR
(PV array) next. The green LED indicator will
light if sunlight is present.
3
6. Connect the
LIGHT
last. If the red LED indicator lights, the battery capacity is low and should be charged before completing
the system installation (Refer to Section 6.4).
7. The controller is shipped with a terminal jumper installed. This
sets the controller for charging
SEALED
batteries.
If a
FLOODED
battery is being used, simply remove the jumper
to optimize the battery charging for a flooded battery. If the
jumper is connected again, the charging will return to the setpoints for a sealed battery (Refer to Section 6.4.)
8. For most effective surge protection, it is recommended that the
negative system conductor be properly grounded.
9. Tur n the rotary
LIGHTING CONTROL
switch to the lighting
option desired (Refer to Section 7.1).
10. Press the
TEST
button and count the number of Red LED flashes
to verify the correct lighting control setting (Refer to Section 7.2).
