Maximum Power Point Tracking Solar Charge Controller Basics

The Maximum Power Point Tracking algorithm is used in the charge controllers under some provisions to obtain the highest possible usable power from the PV module. The voltage at which the PV module can render optimal energy is called the peak power voltage. Power generation capacity may vary in terms of solar radiation, atmospheric temp, and the temperature of solar cells. 

When tested at a cell temperature of 25 ° C, the standard PV module produces power with the highest voltage of around 17 V; it can fall to approximately 15 V on a scorching day and spike to 18 V on a very chilly day.

MPPT solar charge controller:

An MPPT solar charge controller is a device secured with MPPT algorithm responsible for optimising the current moving into the battery from the PV module.

Maximum Power Point Tracking Solar Charge is a DC to DC converter that works by switching the DC input from the PV module to AC and transforming it back to a different DC voltage and current to fit the PV module precisely to the battery.

Principal characteristics of MPPT solar charge controller:

  • In any app where the PV module is an energy source, the MPPT solar charge controller is used for correcting to identify the fluctuations in the current-voltage ratio of the solar cell.
  • The solar charge controller is essential for any solar power systems for extracting the highest power from the PV module; it forces PV module to perform at a charge close to a max PowerPoint to draw the fullest power accessible.
  • The device enables users to pick a PV module with a greater output voltage than the battery system’s operating voltage.
  • It is also feasible to install this solar charge controller to renewable energy sources, such as water and wind turbines.
