3. Safety Information
Please read all instructions and warnings carefully before installation and operation. Failure to follow these instructions may result in electric shock, fire, or severe injury.
- Ensure all connections are tight and correct to prevent loose connections that can cause excessive heat.
- Always connect the battery first, then the solar panel, and finally the load. Disconnect in reverse order.
- Do not disassemble or attempt to repair the controller yourself. Contact qualified personnel for service.
- Install the controller in a well-ventilated area, away from flammable materials and direct sunlight.
- Wear appropriate personal protective equipment (PPE) during installation, including eye protection and insulated gloves.
- Ensure the solar panel's open-circuit voltage (Voc) does not exceed the controller's maximum input voltage (100V).

4. Package Contents
Verify that all items are present in the package:
- Power Queen 30 Amp MPPT Solar Charge Controller (Model: P24V30A-MPPT-BT-B)
- Copper wire connector (accessory)
- User Manual (this document)
5. Setup
5.1 Mounting the Controller
Mount the controller vertically on a non-flammable surface in a dry, well-ventilated area. Ensure adequate clearance around the unit for heat dissipation. Avoid direct sunlight, high temperatures, and moisture.
5.2 Wiring Connections
Follow the wiring order precisely to prevent damage to the controller or other components. Use appropriate wire gauges for your system's current and distance.
- Connect the Battery: Connect the battery cables to the battery terminals on the controller (positive to positive, negative to negative). Ensure a secure connection. The controller will power on once the battery is connected.
- Connect the Solar Panel: Connect the solar panel cables to the PV terminals on the controller (positive to positive, negative to negative). Ensure the solar panel's open-circuit voltage does not exceed 100V.
- Connect the DC Load (Optional): If using a DC load directly from the controller, connect the load cables to the load terminals (positive to positive, negative to negative).
5.3 Initial Configuration
After connecting the battery, the controller will automatically detect the system voltage (12V or 24V). You may need to manually set the battery type if it's not LiFePO4 (the default). Refer to the 'Operating Instructions' section for details on navigating the LCD menu and setting parameters.
