User's Manual

Safety Instructions

• Make sure your battery has enough voltage for the controller to recognize the battery type before first installation.
• The battery cable should be as short as possible to minimize loss.
• This controller is suitable for all kinds of lead-acid batteries (including Sealed, Flooded, AGM, GEL), lithium ion batteries, and lithium iron phosphate batteries.
• The charge regulator is only suitable for regulating solar modules. Never connect another charging source to the charge regulator.

Product Features

• Built-in industrial micro controller.
• IR remote control, LED display, auto memory function, IP68 protection.
• Fully 4-stage PWM charge management.
• Built-in short-circuit protection, open-circuit protection, reverse protection, over-load protection.
• Dual MOSFET reverse current protection, low heat production.

System Connection

• Connect the battery to the charge regulator - plus (+) and minus (-). It will auto adapt the battery type.
• Connect the photovoltaic module to the regulator - plus (+) and minus (-).
• Connect the consumer to the charge regulator - plus (+) and minus (-).

The reverse order applies when uninstalling!

An improper sequence order can damage the controller!

Diagram Description: The diagram illustrates the wiring connections for the solar charge controller. It shows a battery connected to the regulator's battery terminals (+ and -), a solar panel connected to the regulator's PV terminals (+ and -), and a load connected to the regulator's load terminals (+ and -). Indicator lights for battery power (Green flash for over-voltage, Green on for high, Yellow on for medium, Red on for low, Red slow flash for very low), charge status (fast flashing for equalization/buck charge, solid on for acceptance, slow flashing for float, off for no charge), and output status (solid on for output normal, off for output close, slow flashing for over-current, fast flashing for short-circuit) are depicted. An IR receiver and IR indicator are also shown.

Setting/System Mode

Battery Type Select:

• When the controller is energized, it recognizes the battery voltage type. If the battery voltage is lower than 18V, it is identified as the 12V system, and if it is higher than 18V, it is identified as the 24V system.
• After identifying the system voltage, the user can press the infrared remote controller to choose a battery type. After receiving the signal, the controller's blue light flashes, and the setting is completed without restarting.
• The controller supports 3 types of batteries:
  • 12V lead-acid batteries (including Sealed, Flooded, AGM, GEL)
  • 11.1V lithium ion battery (3 series, 3*3.7V, including capacity and power type)
  • 12.8V phosphoric acid iron lithium battery (4 series, 4*3.2V)
• If it is a 24V system, it corresponds to:
  • 24V lead-acid batteries (including Sealed, Flooded, AGM, GEL)
  • 22.2V lithium ion battery (6 series, 6*3.7V, including capacity and power type)
  • 25.6V phosphoric acid iron lithium battery (8 series, 8*3.2V)
• After the battery type is set, the user can set the work mode of the load:
  • 24H mode: Normally open mode for the load, meaning the load output is always connected (unless low power protection is active).
  • Dusk to Dawn mode (D2D): System load is disconnected during the daytime and connected at night time.
  • 1-13H mode: System load is connected when night falls and disconnected after a 1-13 hour timer. The D2D mode and the timer mode are used for solar energy lighting systems, which are fully automatic control.
• When it is necessary to temporarily connect or disconnect the load, press the manual button [H], enter manual mode, and then press [ON/OFF] to manually switch the load. This function is generally used to test the connection of the load.

Diagram Description: The image shows an IR remote control with numbered buttons (1-12) and additional function buttons. It also depicts various indicator lights and system mode selections like 'System mode', 'Load connect 24hours', 'Dusk to Dawn', and 'Load on after sunset and closed after 1-13 hours'. The remote allows users to select battery types and control load output modes. An IR indicator light and a status indicator for the remote are also visible.
