5. Setup and Installation
Follow these steps for proper installation of your solar charge controller. Ensure all connections are secure and correct to prevent damage to the system.
5.1. Wiring Diagram
The following diagram illustrates the correct connection sequence for the solar panel, battery, and loads.
5.2. Connection Steps
- Connect the Battery: Connect the battery to the controller's battery terminals (marked with '+' and '-'). Ensure correct polarity. The controller will automatically identify the battery system voltage (12V/24V/36V/48V).
- Connect the Solar Panel: Connect the solar panel to the controller's PV input terminals (marked with 'PV+' and 'PV-'). Ensure correct polarity.
- Connect the Load: Connect your DC loads to the controller's load terminals (marked with 'LOAD+' and 'LOAD-'). For AC loads, connect them via an inverter, which is then connected to the battery.
Important: Always connect the battery first, then the solar panel, and finally the load. Disconnect in the reverse order: load first, then solar panel, then battery.
6. Operating Instructions
6.1. Monitoring System Status
The LCD display provides real-time information about your solar system. Use the Up (▲) and Down (▼) buttons to cycle through different parameters such as PV voltage, battery voltage, charging current, load current, and accumulated energy (kWh).
6.2. Configuring Settings
To enter the settings menu, press the SET button. Use the Up (▲) and Down (▼) buttons to navigate through options and adjust values. Press SET again to confirm and save changes. If no button is pressed for 10 seconds in the settings menu, the controller will automatically exit setup mode.
6.3. Load Control
The controller can manage DC loads connected to its load terminals. Press the ESC button to manually switch the load on or off. The controller also supports programmable load control modes (e.g., dusk-to-dawn, timed operation) which can be configured in the settings menu.
6.4. Battery Charging
The MPPT algorithm ensures efficient charging of your battery. The controller will automatically stop charging when the battery is fully charged to prevent overcharging and prolong battery life.
7. Maintenance
- Regular Inspection: Periodically check all wiring connections for tightness and corrosion.
- Cleaning: Keep the controller's casing clean and free from dust. Use a dry cloth for cleaning. Do not use liquids or solvents.
- Ventilation: Ensure that the ventilation openings are not blocked to allow for proper heat dissipation.
- Battery Health: Monitor battery voltage and health regularly, especially for lead-acid batteries, to ensure optimal performance of the solar system.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | Battery not connected or low voltage; reversed polarity. | Check battery connections and voltage. Ensure correct polarity. |
| No charging from solar panel | Solar panel not connected; low sunlight; panel voltage too low/high. | Check solar panel connections. Verify sunlight conditions. Ensure PV voltage is within specified range (18-160V). |
| Load not working | Load not connected; load current too high; battery low. | Check load connections. Reduce load or check battery charge level. Manually switch load on with ESC button. |
| Abnormality/Fault icon displayed | System error, over-voltage, over-current, short circuit. | Refer to the LCD display for specific fault codes. Disconnect and reconnect components in correct order. Consult specifications for limits. |
