5. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your MPPT solar charge controller. Follow these steps carefully.
5.1 Mounting the Controller
- Choose a dry, well-ventilated location, protected from direct sunlight, high temperatures, and moisture.
- Ensure there is sufficient clearance around the controller for proper heat dissipation.
- Mount the controller vertically on a non-flammable surface using appropriate fasteners through the mounting holes.
5.2 Wiring Connections
Connect the components in the following order to ensure safety and proper functionality:
- Connect the Battery: Connect the battery to the controller's battery terminals. Ensure correct polarity (positive to positive, negative to negative). The controller will automatically detect the battery voltage.
- Connect the Solar Array: Connect the solar panels to the controller's PV input terminals. Ensure correct polarity. Do not exceed the maximum open-circuit voltage (160VDC) or maximum input power for your system voltage.
- Connect the Load (Optional): If using the load output, connect your DC loads to the controller's load terminals. Ensure correct polarity.
Warning: Always connect the battery first and disconnect the solar array first when disassembling the system.
