FAQ

Q: What are the key considerations for installing the wireless NCU antenna?

A:

Clearance requirements: There should be no large metal obstructions within a 3-meter radius of the antenna.

Installation height: Ideally, mount the antenna at the highest point of the tracker structure or on a dedicated pole to avoid signal attenuation caused by ground-level vegetation or standing water.

Directionality: If using a directional antenna, the main lobe must face directly toward the area with the highest density of TCUs, while avoiding sources of strong interference.

Q: How does the PV Communication Unit (NCU) coordinate with PV cleaning robots?

A: The NCU acts as a scheduling base station for the cleaning robots. When the SCADA system determines that cleaning is required, the NCU first adjusts the tracker structures in its zone to a horizontal position (0°) to provide a flat path for the robot; once cleaning is complete, the NCU reverts to automatic tracking mode.
