This solar charge controller is designed for 12V/24V systems with automatic recognition. Important: Always connect the battery to the controller first, then connect the solar panels. The controller will start automatically.

Installation
The controller should be installed indoors in a dry, well-ventilated area by a qualified electrician. Do not wear jewelry during installation and ensure the power supply is cut off before starting.


- Measure and drill 4x6mm holes on the wall.
- Install the controller using M4 self-drilling screws.
- Ensure proper airflow around the unit as it may get warm during operation.
Wiring
Follow the wiring sequence carefully to avoid damage:

- Connect the battery to the controller.
- Connect the solar panels to the controller.
- Connect the DC load (if applicable).
Operation and Settings
The controller features an LCD display and a button for configuration. To enter settings, long-press the button for 3 seconds. Short-press to navigate, long-press to select/edit, and long-press to save changes.
Battery Types: The controller supports AGM, GEL, and LiFePO4 batteries. Note that settings for 12V batteries must be doubled when using a 24V battery system.
DC Output Modes:
- All day mode: Load is on all day.
- Automatic mode: Load turns on when there is no PV input and turns off when PV input starts (3-minute delay).
- Manual mode: Double-click the button to turn the load on or off.
Troubleshooting
If the controller displays an error code, refer to the following:
- E01: Battery voltage too high.
- E02: Battery voltage too low.
- E03: PV input voltage too high.
- E04: PV input current too high.
- E05: Output current too high.
- E06: Internal temperature too high.
- E07: Load short-circuit protection.
- E08: PV short-circuit protection.
