4.3 Installation Steps:
- Mounting: Choose a suitable location for mounting the controller, ensuring adequate ventilation and protection from environmental elements. Use the provided mounting holes.
- Battery Connection: Connect the battery cables to the controller's battery terminals first. Ensure correct polarity (+ to + and - to -).
- Solar Panel Connection: Connect the solar panel cables to the controller's PV terminals. Verify correct polarity.
- Load Connection (Optional): If using the load output, connect your DC load to the controller's load terminals.
- Power On: Once all connections are secure, the controller will power on and begin operation.
5. Operating Instructions
The controller features an LCD display and four buttons for navigation and settings adjustment.
5.1 Display and Buttons
The LCD provides real-time system information. Use the buttons (PV, BAT, DC, SET) to cycle through display screens and adjust parameters.
5.2 Battery Type Selection
The controller automatically detects system voltage. For optimal charging, ensure the correct battery type (sealed, flooded, gel, or lithium) is selected in the settings. Refer to the manual's detailed settings section for specific battery parameter adjustments, especially for lithium batteries.
5.3 Charging Stages
The controller employs a 4-stage charging algorithm:
- Bulk Charge: Charges the battery at maximum current until voltage reaches the boost voltage.
- Boost Charge: Charges at a constant voltage for a set period to ensure full charge.
- Float Charge: Maintains the battery at a lower voltage to prevent self-discharge and overcharging.
- Equalization: (For flooded batteries) Periodically overcharges the battery to balance cell voltages.
