4.2 Camau Gosod
- Mowntio: Mount the controller vertically on a non-flammable surface in a cool, dry, and well-ventilated area. Ensure adequate clearance around the unit for heat dissipation.
- Cysylltiad Batri: Connect the battery cables to the controller's BAT+ and BAT- terminals. Ensure correct polarity. The controller will automatically detect the battery voltage (12V, 24V, neu 48V).
- Cysylltiad Panel Solar: Connect the solar panel array cables to the controller's PV+ and PV- terminals. Ensure correct polarity. The controller will begin charging the battery.
- Cysylltiad Llwyth (Dewisol): If using the load output, connect your DC loads to the OUT+ and OUT- terminals. Ensure the total current draw does not exceed the controller's rated load current.
- Gwirio Cysylltiadau: Double-check all connections for tightness and correct polarity before powering on the system.
Important: Always connect the battery first and disconnect it last. Failure to follow this sequence may damage the controller.
5. Cyfarwyddiadau Gweithredu
The controller's LCD display provides real-time system status and allows for parameter adjustments. The control buttons are PRG/ESC, Up (▲), Down (▼), and ENTER.
5.1 Swyddogaethau Arddangos LCD
The LCD cycles through various screens displaying system information. You can manually cycle through screens using the Up/Down buttons or enter parameter settings using PRG/ESC and ENTER.
- Prif Arddangosfa: Shows charging status, battery level, and output status.
- Cumulative Power Generation: Displays total energy generated by the solar panels.
- PV Cyftage and Load Power: Shows current solar panel voltage and load power consumption.
- Batri Cyftage and Load Current: Yn arddangos batri cyfredol cyftage a llwytho cerrynt.
- Accumulated Discharge: Shows total energy discharged from the battery.
