Installation and Operation
WARNING: Follow all safety precautions of the battery manufacturer. Proper ventilation
must be provided for the batteries. Most batteries produce hydrogen gas when charging,
which is extremely explosive. Provide adequate battery ventilation.
DO NOT Expose the battery to open flame, matches, cigarettes or sparks.
CAUTION: DO NOT EXCEED THE UNIT'S VOLTAGE AND CURRENT RATINGS:
• Do not exceed the maximum solar array voltage rating of 26 volts.
• Do not exceed the maximum current rating of 30 amps.
CAUTION: DO NOT DEVIATE FROM THE RECOMMENDED WIRING INSTRUCTIONS:
• Do not reverse Battery (+) and Battery (-) connections to the controller.
• Do not reverse the Battery and Solar Array connections to the controller.
• Unplug the controller from the solar array and battery before attempting any maintenance
or cleaning.
• Do not disassemble the controller. Take it to a qualified service center when service or
repair is required. Incorrect reassembly may result in a risk of damage the unit.
• Installation should be made by a qualified person.
• Save these instructions for future reference.
PERSONAL PRECAUTION:
• If battery acid contacts skin or clothing, wash immediately with soap and water. If acid
enters eye, immediately flush eye with running cold water for at least 10 minutes and get
medical attention immediately.
• Never smoke or allow a spark or flame in vicinity of battery.
• Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark or
short-circuit battery or other electrical part that may cause explosion.
1. Mounting
1.1 Mounting Consideration: - The solar controller is designed to be flush mounting or wall
mounting.
1.2 Flush mounting: The flush mounted unit requires a rectangular cutout in the mounting
surface with sufficient space (2-3 inches) behind to accommodate the controller.
1.3 Wall mounting: The wall-mounted unit is installed onto a wall surface using two
mounting screws. Electrical connections are made to the back of the controller. Wiring can be
run down the wall or through a hole in the wall directly below the controller.
1.4 Recommended Battery Capacity : 12V 45AH minimum.
2. Connection Procedures (refer to Connection diagram)
2.1 Fix the mounting of the solar controller panel.
2.2 Select Lead-Acid or Gel-cell Battery modes.
2.3 Connect the solar panel positive side to the solar controller ARRAY POSITIVE + by a suitable wire
(Be careful not to short circuit the solar array.)
2.4 Connect the solar panel negative side to the solar controller ARRAY NEGATIVE– by a suitable wire
2.5 Connect the Lead-Acid or Gel-cell battery positive side to the solar controller BATTERY POSITIVE +
by a suitable wire.
