5. Setup and Installation
Follow these steps for proper installation of your solar panel kit. Refer to the wiring diagram for visual guidance.
5.1 Component Placement
- Solar Panels: Mount panels in a location that receives maximum direct sunlight throughout the day, free from shading. Use the provided Z-brackets for secure mounting.
- MPPT Controller: Install the controller in a cool, dry, and well-ventilated area, close to the battery.
- Battery: Place the LiFePO4 battery in a secure, dry, and temperature-controlled environment.
- Inverter: Mount the inverter in a well-ventilated area, away from flammable materials, and as close to the battery as practical to minimize cable length.
5.2 Wiring Instructions
Important: Always connect the battery to the charge controller first, then the solar panels, and finally the inverter. Disconnect in reverse order.
- Connect Solar Panels: Connect the four 100W solar panels in parallel. This means connecting all positive terminals together and all negative terminals together. Use the provided Y-branch connectors to combine the panel outputs.
- Connect Panels to MPPT Controller: Connect the combined positive and negative outputs from the solar panels to the PV input terminals on the 40A MPPT solar charge controller. Ensure correct polarity.
- Connect Battery to MPPT Controller: Connect the 12V 100Ah LiFePO4 battery to the battery terminals on the MPPT solar charge controller. Ensure correct polarity (positive to positive, negative to negative). The controller will detect the 12V system voltage.
- Connect Inverter to Battery: Connect the 1100W inverter directly to the 12V 100Ah LiFePO4 battery terminals. Ensure correct polarity. The inverter typically has thicker cables for this connection.
