Basics Of Maximum Power Point Tracking Mppt Solar Charge Controller
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.
Basics of maximum power point tracking mppt solar charge controller. 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. This means it reduces the wire size needed while retaining full output of pv module. For example optical power transmission and thermophotovoltaics. 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.
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. So what exactly is maximum power point tracking mppt. 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 charge controller simple guide what is maximum power point tracking.
A simplified block diagram of the functional concept is shown in figure 2. 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. Although it primarily applies to solar power the principle applies generally to sources with variable power. At its most basic mppt is simply helps your solar panels produce more power.
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. 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. The dc power generated by the solar panel can be efficiently stored in a battery. The maximum power point tracking mppt charge controller incorporates pwm and a dc to dc converter.
