Differences Between PWM and MPPT Charge Controllers
The primary difference between PWM (Pulse Width Modulation) and MPPT (Maximum Power Point Tracking) charge controllers lies in efficiency.
- MPPT controllers are about 30% more efficient in energy conversion compared to PWM controllers.
- PWM systems require the panel voltage to match the battery voltage for optimal performance.
Important Installation Note
-This product requires installation by a qualified PV installer.
-The installer must issue a Certificate of Compliance (COC) to ensure safe and regulation-compliant installation.
-For best results, it is recommended to use ECCO Batteries and Solar Panels to guarantee quality and performance.
