Malfunctioning Charge Controller
The charge controller manages the flow of power between the panels, battery, and devices. If it’s faulty, the system may not work.
- Role in charging process: The controller ensures the battery doesn’t overcharge or discharge too quickly.
- Potential issues: A broken controller can misinterpret power levels, causing the clicking sound.
Overcurrent and Short Circuit Issues
Electrical problems like overcurrent or short circuits can activate the charger’s protective mechanisms.
- Overcurrent situations: Drawing too much power from the system can cause the relay to shut off and click.
- Short circuits: Faulty wiring or damaged components can create a short circuit, disrupting the system.
