Basics Of Maximum Power Point Tracking Mppt Solar Charge Controller

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.

Basics of maximum power point tracking mppt solar charge controller.

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. 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. The dc power generated by the solar panel can be efficiently stored in a battery. This means it reduces the wire size needed while retaining full output of pv module.

The maximum power point tracking mppt charge controller incorporates pwm and a dc to dc converter. Mppt charge controller simple guide what is maximum power point tracking. The maximum power point tracking mppt can be implemented in several ways so the figure illustrates only the basic functions. A simplified block diagram of the functional concept is shown in figure 2.

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. At its most basic mppt is simply helps your solar panels produce more power. 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 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.

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. Although it primarily applies to solar power the principle applies generally to sources with variable power. For example optical power transmission and thermophotovoltaics. 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.
