Solar Controller FAQ Section
What is the difference between PWM and MPPT solar controllers?
PWM (Pulse Width Modulation) controllers are simpler and more affordable but less efficient, typically converting 70-80% of solar energy. MPPT (Maximum Power Point Tracking) controllers are more advanced, achieving 93-99% efficiency by continuously adjusting to extract maximum power from solar panels, especially beneficial in cold weather or low light conditions.
How do I choose the right size solar controller for my system?
Calculate your total solar panel current (Watts ÷ Battery Voltage) and add 25% safety margin. For example, with 600W panels on a 12V system: 600W ÷ 12V = 50A + 25% = 62.5A → choose a 70A controller. Always check both current and voltage compatibility between your panels, controller and battery bank.
How often should I maintain my solar controller?
Modern solar controllers require minimal maintenance. Check connections every 6 months for corrosion, ensure proper ventilation, clean dust from heatsinks annually, and verify settings match your battery type (AGM, Gel, Flooded, Lithium). Update firmware if your model supports it for optimal performance.
