12 Volt 30 Amp Digital Solar Charge Controller #23125
Installation & Operation Manual
IMPORTANT SAFETY INSTRUCTION: SAVE THESE INSTRUCTIONS
THIS MANUAL CONTAINS IMPORTANT SAFETY AND OPERATING INSTRUCTIONS FOR 12V
SOLAR CHARGE CONTROLLER. KEEP IT WITH OR NEAR THE CONTROLLER AT ALL TIMES.
The charge controller is designed to protect your 12 Volt Lead-acid or Gel-cell battery from being overcharged by
solar panel, which prevents discharging of battery during nighttime. This controller reduces overall system
maintenance and prolongs your battery life. It will display the charging current or battery voltage from the LCD digital
meter; also indicate the battery condition with LED bar-graph. This controller is design to work with all kinds of 12
Volt solar panels for indoor use.
WARNING: RISK OF EXPLOSIVE GAS- Working in the vicinity of a lead acid battery is dangerous. Batteries generate
explosive gases during normal battery operation. Always work in a well-ventilated area.
• DO NOT smoke, strike a match, or cause a spark in vicinity of battery during charging.
• CAUTION: DO NOT EXCEED THE UNIT’S VOLTAGE AND CURRENT RATINGS:
• MAXIMUM solar array voltage rating of 25 volts.
• MAXIMUM charging current 30 amps.
• CAUTION: DO NOT DEVIATE FROM THE RECOMMENDED WIRING INSTRUCTIONS:
• DO NOT reverse the Battery and Solar Array connections to the controller.
• DISCONNECT 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 to the Solar system.
• Installation should be made by a qualified person.
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.
• Be extra cautious to reduce risk of dropping a metal tool onto battery. It might sparks or short-circuit the battery or other
electrical parts that may cause explosion.

Installation and Operation
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.
