4. Setup Instructions
Connection Steps
Follow the correct installation sequence to ensure proper operation and prevent damage. The wiring order is crucial:
- Connect the Battery
- Connect the Solar Panels (PV Array)
- Connect the DC Load
Important Wiring Instructions:
- The controller wiring must be connected to the battery first.
- Then, connect the PV plate (solar panels).
- Finally, connect the DC load.
- Ensure the battery has sufficient voltage for the controller to correctly identify the battery type.
- For a 12V battery, the voltage should be higher than 10V.
- For a 24V battery, the voltage should be higher than 20V.
- For a 36V battery, the voltage should be higher than 30V.
- For a 48V battery, the voltage should be higher than 42V.

Precautions
- This controller automatically adapts to 12V/24V/36V/48V systems. For initial installation, ensure the battery has sufficient voltage for correct identification.
- Install the controller as close to the battery as possible to minimize voltage drop from long wires, which can affect accurate voltage readings.
- This controller is suitable for lithium batteries and various lead-acid batteries (including open, sealed, and colloidal types). Note that lithium batteries may require manual adjustment of overcharging voltage. Do not use other battery types such as nickel-metal hydride batteries.
- The controller is designed to use only photovoltaic panels as the charging source. Do not connect DC or other power supplies as charging sources.
- The controller will generate heat during operation. Ensure it is installed on a flat, well-ventilated surface to facilitate heat dissipation.
5. Operating Instructions
Working Mode Selection
The controller offers 7 types of working modes:
- Charging Mode: In this mode, the controller will only charge the battery and never discharge.
- Light Control Mode: When the controller detects nightfall, it will delay ten minutes, then begin discharging. When it detects daytime, it will delay ten minutes, then stop discharging.
- Light and Time Delay Control Mode: Similar to Light Control Mode, but after detecting nightfall and a ten-minute delay, it starts discharging and counts down a set timer. Discharge stops when the timer reaches zero. The maximum duration for this delay is 23:59.
- Universal Control Mode: Under normal operating conditions, the controller will continuously discharge.
- Manual Control Mode: Use the “▼” button to manually toggle discharging on or off.
- Timing Control Mode: The controller will open or close the discharge at regularly scheduled times.
- Test Mode: This mode is similar to Light and Time Delay Control Mode but has a reduced time delay of only ten minutes.
Controller Display Areas
The LCD provides dynamic information about the system's status:
- 1. Battery Work Status Display Area: Shows the current status of the battery.
- 2. Solar Panel Operating Status: Displays information related to the solar panel's operation.
- 3. Load Output Status and Parameters: Shows the status of the connected load and various parameters.
- 4. Mode Control Display Area: Indicates the currently selected working mode.
- 5. Normal and Fault Status Display Area: Provides information on normal operation or any detected faults.

6. Maintenance
To ensure the longevity and optimal performance of your POWLSOJX MPPT Solar Charge Controller, regular maintenance is recommended:
- Keep Clean: Periodically clean the exterior of the controller to prevent dust and debris buildup, which can hinder heat dissipation.
- Check Connections: Regularly inspect all wiring connections (battery, solar panels, load) to ensure they are secure and free from corrosion. Loose connections can lead to power loss or system malfunction.
- Ensure Ventilation: Confirm that the controller is installed in a well-ventilated area and that its heat sink is not obstructed. Proper airflow is essential for dissipating heat generated during operation.
- Battery Health: Monitor your battery's health and voltage levels. Ensure the battery is always above the minimum voltage required for the controller to operate correctly.

7. Troubleshooting
Refer to the table below for common issues and their solutions:
| Malfunction Phenomenon | May Cause | Troubleshooting Method |
|---|---|---|
| Sunshine is sufficient but not charging | Photovoltaic board open circuit or reverse connection | Re-link good photovoltaic panels |
| The load logo does not light up | Mode setting error | Re-set the mode |
| The load logo does not light up | The battery voltage is too low | Recharge the battery |
| Load mark flashes slowly | Load overcurrent | Reduce load power |
| Load logo flashes quickly | Short circuit protection | Remove short circuit, controller will automatically recover |
| The controller does not light up | The battery voltage is too low / reverse connection | Replace the battery / check reverse connection |
