Professional MPPT solar charge controller factory in China
All of the MPPT solar charge controllers have passed CE certification.
MPPT: Maximum Power Point Tracking
The MPPT controller utilizes Solar Maximum Power Point
Tracking (MPPT) technology to extract maximum power from the solar array. The tracking algorithm is fully automatic and does not require user adjustment. MPPT technology tracks the array maximum power point as it varies with weather conditions, ensuring that maximum power is harvested from the array throughout the course of the day.
