MPPT, the full name of Maximum Power Point Tracking, is the maximum power point tracking. MPPT street light controller is now more popular in the market. Today I will share with you the circuit principle of MPPT street light controller.

MPPT wind solar street light controller

The principle of MPPT street light controller is to first detect the DC voltage and output current of the main circuit, then calculate the output power of the solar array, and finally realize the tracking of the maximum power point.

Why use MPPT street light controller?

The performance of solar cell modules can be represented by U-I curve. The instantaneous output power (U*I) of the battery pack moves on this U-I curve. The output of the battery pack is affected by the external circuit. Maximum power tracking technology is to use power electronic devices with appropriate software to make the battery assembly always output the maximum power. If there is no maximum power tracking technology, the output power of the battery module cannot reach the best (large) value under any circumstances, thus reducing the utilization rate of the solar battery module.

The MPPT street light controller can detect the voltage generated by the solar panel in real time, and track the maximum voltage and current value (VI), so that the system can charge the battery with the maximum power output. Used in solar photovoltaic systems to coordinate the work of solar panels, batteries, and loads, it is the brain of the photovoltaic system.
