Q1. How do I know if the controller is working properly?

The controller usually has LED indicators that show the charging status, battery level, and any fault conditions. Refer to the user manual for a detailed explanation of the indicator lights and their meanings.

Q2. How does a wind turbine controller work?

The controller monitors the voltage and current from the wind turbine. It prevents overcharging of the batteries by diverting excess power or stopping the turbine when the batteries are fully charged. It also protects the system from overvoltage and short-circuits.
