This diagram illustrates the typical connection setup for the solar charge controller, showing how the solar array, battery bank, and DC load are connected to the controller. It also indicates optional connections for a temperature sensor, WiFi module, and PC software via RS485.
- Connect the Battery: Connect the positive and negative terminals of the battery to the BAT+ and BAT- terminals on the controller. Ensure correct polarity. The controller will automatically detect 12V or 24V.
- Connect the Solar Panels: Connect the positive and negative leads from your solar array to the PV+ and PV- terminals. Ensure the solar panel's open-circuit voltage does not exceed the controller's maximum input voltage.
- Connect the DC Load (Optional): Connect your DC loads to the LOAD+ and LOAD- terminals. Ensure the total current draw does not exceed 20A.
- Connect Temperature Sensor (Optional): For accurate temperature compensation, connect the external temperature sensor to the 'Temp' terminal.
- Connect RS485 (Optional): For remote monitoring and control, connect an RS485 cable to the designated port.
4.3 Battery Type Selection
The controller supports various battery types. Refer to the controller's menu for selecting the appropriate battery type (Wet, AGM, Gel, Lithium, or Custom) to ensure correct charging parameters.
5. Operating Instructions
5.1 LCD Display Information
The LCD display provides real-time operational data. Use the control buttons (PV, BAT, DC, S) to cycle through different display screens:
- Solar Voltage (PV): Displays the current voltage from the solar panels.
- Solar Current (PV): Displays the current flowing from the solar panels.
- Battery Voltage (BAT): Displays the current battery voltage.
- Battery Current (BAT): Displays the current flowing into or out of the battery.
- Load Current (DC): Displays the current being drawn by the DC loads.
- System Status: Icons and indicators for charging status, battery level, and fault conditions.
5.2 Load Control
The controller features programmable load control. This allows you to set timers or voltage thresholds for turning the DC load output on or off, protecting the battery from over-discharge.
5.3 RS485 Communication
The RS485 interface enables connection to a computer or other monitoring devices for advanced system management, data logging, and remote control. Refer to the separate software manual for detailed instructions on using the RS485 interface.
6. Maintenance
Regular maintenance ensures optimal performance and longevity of your solar charge controller.
- Cleaning: Periodically clean the controller's exterior with a dry cloth. Ensure ventilation openings are free from dust and debris.
- Connection Checks: Annually inspect all wiring connections for tightness and corrosion. Loose connections can cause overheating and poor performance.
- Battery Inspection: Regularly check battery terminals for corrosion and ensure proper electrolyte levels for flooded batteries.
- System Monitoring: Monitor the display for any unusual readings or fault indicators.
