Prepare the Site and Gather Tools
Start by selecting a location that receives full sun for most of the day. Measure the mounting surface to ensure the panel's 0.55m × 0.34m footprint fits. Gather a drill with 1/4‑inch bits, a mounting bracket, a 12V charge controller, a 12V battery, a 12‑V DC‑DC converter (if needed), a 5‑amp fuse, and a 12‑V DC cable. If mounting on a roof, use stainless‑steel screws and sealant to prevent leaks.

Mount the Panel
Attach the mounting bracket to the chosen surface using the provided screws. Tighten them in a cross pattern to distribute load. Align the panel's mounting holes with the bracket, then secure it with bolts. If using a pole mount, center the panel on the pole and secure it with a clamp. Verify the panel is level to avoid stress on the wiring.
Wire the System
Connect the panel's positive (+) and negative (–) terminals to the charge controller's input. Use a 12‑V 5‑amp fuse on the positive line within 5 cm of the controller to protect against short circuits. Route the cables along the mounting structure and secure them with zip ties. From the controller, run a 12‑V cable to the battery's positive terminal, again protecting it with a fuse. If the battery is 12 V, no DC‑DC converter is needed; otherwise, connect the converter between the controller and battery.
Configure the Charge Controller
Set the controller's battery type to "Lead‑Acid" or "Lithium" based on your battery. Adjust the charging voltage to match the battery's specifications—12 V batteries typically use 13.8 V to 14.4 V. Enable the "Low‑Voltage Disconnect" feature to prevent deep discharge. Check the controller's display for a stable voltage reading after connecting the panel.
Test and Monitor
With the panel facing the sun, observe the controller's output voltage; it should rise to the set charging voltage within a few minutes. Verify the battery's state of charge increases. Inspect all connections for tightness and check for any heat buildup. Once confirmed, the system is ready for use. Periodically clean the panel and monitor the controller's logs to ensure consistent performance.
