Basics Of Maximum Power Point Tracking Mppt Solar Charge Controller

Although it primarily applies to solar power the principle applies generally to sources with variable power.

Basics of maximum power point tracking mppt solar charge controller.

At its most basic mppt is simply helps your solar panels produce more power. Maximum power point tracking or an mppt solar charge controller is a charge controller embedded with mppt algorithm to maximize the amount of current going into the battery from the photo voltaic or pv module. A simplified block diagram of the functional concept is shown in figure 2. Using this clever technology mppt solar charge controllers can be up to 30 more efficient depending on the battery voltage and type of solar panel connected.

Mppt uses dc dc converter topology which takes dc input from the solar panel changes it into ac and converting it back to a different. Mppt charge controller simple guide what is maximum power point tracking. Maximum power point tracking mppt or sometimes just power point tracking ppt is a technique used commonly with wind turbines and photovoltaic pv solar systems to maximize power extraction under all conditions. The maximum power point tracking mppt system is an electronic system that enables the photovoltaic panel to output more power by adjusting the working state of the electrical module.

To put it simply they convert a higher voltage dc output from solar panels and a few wind generators down to the lower voltage needed to charge batteries. Mppt or maximum power point tracking controllers are far more advanced than pwm controllers and enable the solar panel to operate at its optimum voltage for maximum power output. So what exactly is maximum power point tracking mppt. An mppt or maximum power point tracker is an electronic dc to dc converter that optimizes the match between the solar array pv panels and the battery bank or utility grid.

The maximum power point tracking mppt charge controller incorporates pwm and a dc to dc converter. For homeowners interested in solar it helps to know the basics of mppt what it is and how it fits into a solar installation so you can make sure you re getting the most benefit from your installation. With a mppt solar charge controller users can wire pv module for 24 or 48 v depending on charge controller and pv modules and bring power into 12 or 24 v battery system. The maximum power point tracking mppt can be implemented in several ways so the figure illustrates only the basic functions.
