What are the key features to look for in a solar charge controller?
When selecting a solar charge controller, there are several key features to consider to ensure optimal performance and compatibility with your solar power system. Here are the primary features to look for: Type of Charge Controller PWM (Pulse Width Modulation) vs. MPPT (Maximum Power Point Tracking): PWM Controllers : Simpler and cheaper, suitable for smaller systems with lower efficiency requirements. MPPT Controllers : More efficient, especially in colder conditions, and can handle higher voltage panels, making them ideal for larger systems. Voltage and Current Ratings Voltage Rating: Ensure the controller supports the voltage of your solar panels and battery (e.g., 12V, 24V, 48V). Current Rating: The controller should handle the maximum current output from your solar array (measured in amps). Efficiency Conversion Efficiency: Higher efficiency means less energy loss during the conversion process, especially important for MPPT controllers. Protection Features Overcharge Protec...
