Frequently Asked Questions (FAQ)
1. What does a controller do in an electronic system? It regulates and manages inputs and outputs to maintain system performance and stability — like adjusting voltage, speed, or temperature.
2. What is the difference between a controller and a processor? A processor executes instructions, while a controller governs how those processes interact with physical components or external devices.
3. How does a solar charge controller work? It regulates the voltage and current from solar panels to batteries, preventing overcharging and maximizing energy efficiency.
4. Can I use one controller for multiple systems? Only if it’s designed for multi-function use and supports compatible communication protocols. Otherwise, dedicated controllers are safer.
5. How do I maintain a controller for long-term use? Keep it clean, ensure proper ventilation, update firmware regularly, and inspect connections to prevent overheating or corrosion.
