5. Ntọala na nwụnye
Follow these steps for proper installation of your charge controller:
- Ịkwanye: Choose a dry, well-ventilated location for mounting the controller. Ensure there is sufficient clearance around the unit for heat dissipation. Mount vertically on a non-flammable surface.
- Usoro waya:
- Connect the battery cables to the battery terminals on the charge controller. Ensure correct polarity (+ to + and - to -).
- Connect the solar panel cables to the PV terminals on the charge controller. Ensure correct polarity.
- Connect the load cables to the load terminals on the charge controller (optional). Ensure correct polarity.
- Ihe mmetụta okpomọkụ: Connect the included temperature sensor cable to the designated port on the controller. Place the sensor near the battery to enable accurate temperature compensation for charging.
- Ike izizi: Once all connections are secure, the controller will power on and display system information on the LCD.
Important: Always connect the battery first and disconnect the battery last to prevent damage to the controller.
6. Ntuziaka ọrụ
The LCD display and buttons allow you to monitor and configure the charge controller.
6.1. Ngosipụta Ngosipụta LCD
Use the buttons on the front panel to navigate through the display screens and adjust settings. Refer to the on-screen prompts for specific actions like 'Select' or 'Enter'.
6.2. Battery Type Selection
The controller automatically detects 12V/24V system voltages for non-lithium batteries. For lithium batteries, you must manually adjust the battery voltage setting through the controller's menu to ensure proper charging parameters.
6.3. Lithium Battery Activation
The controller includes a lithium battery activation function. This feature allows charging of deeply discharged lithium batteries that might otherwise be unresponsive.
Figure 6.1: Lithium Activation ON
To prevent over-activation and unnecessary activation, you can turn OFF the lithium activation function. This helps avoid potential damage to the battery if it is not intended for activation.
