Having a Multi Power Point Tracker will, over the course of a year, increase the amount of electricity produced by solar panels by approximately 15%. Solar panels’ photovoltaic modules, or PV modules, absorb sunlight to generate DC power. To function, we must convert the DC solar power into AC. You might believe that converting energy is the only use for a solar inverter, but that’s not the end of it, as MPPT, gives solar inverters a lot more power. Read the article to learn how MPPT work in an inverter, what does MPPT mean on the inverter and other interesting facts.
What Does MPPT Mean on Inverter?
If you still have doubts about how does MPPT work in an inverter, let’s learn what does MPPT mean on an inverter? Maximum Power Point Tracking, also known as MPPT, enables us to extract the most energy possible from sources that have variable energy. There are no limitations to this method.
Photovoltaic cells, or PV cells, are the building blocks of solar panels, which use solar energy to generate electricity. However, because the Sun does not shine equally throughout the day, your solar panels do not receive sufficient sunlight to produce sufficient electricity to meet your needs. Additionally, the weather affects the voltages of the solar panel and battery, which affects the efficiency of the power output. An MPP tracker (Maximum PowerPoint Tracker) can solve this issue. So, how does MPPT work in an inverter to solve this issue?
So, how does MPPT work in an inverter? Home appliances cannot directly utilize solar panel power. The voltage difference is significant. The MPPT method tracks the maximum voltage that solar panels produce and adjusts it to match appliances’ power requirements. It evaluates the output of the PV module, compares it to the voltage of the battery, determines the optimal power that the PV module can produce to charge the battery, and then converts that power into the optimal voltage to ensure that the battery receives the maximum amount of current. It can also provide power.
In the case of an off-grid solar system, the remaining power that isn’t needed right now is stored in a battery and fed into the grid in the case of an on-grid solar system. Also, this is the appliances’ resistance does not e the solar panels to produce less power. Almost all solar inverters today incorporate MPPT technology. This explains how MPPT works in an inverter.
Now, let’s learn about what is an MPPT inverter. MPPT (Maximum PowerPoint Tracking ) is merely a technology. In a solar system, it is very important. Solar panels are used in a solar system to get electricity from the sun. The MPP, or maximum power point, of each solar panel, is unique. The panel produces the most power when it operates at its MPP. The MPPT method monitors this particular power. The goal is to ensure that a solar panel always operates at its maximum power, or as close to it as possible so that it can generate as much electricity as possible.
Whenever you discuss what is MPPT inverter, the answer lies that an MPPT solar inverter is one that has a built-in DC-to-DC converter. Installing a solar inverter without a Maximum Power Point Tracker carries significant risks, the most significant of which is that solar panels won’t operate to their full potential. Now, let’s see what is the function of MPPT in solar inverters.

We envision a world where clean, renewable energy sources power our lives, and recycling becomes an integral part of everyday living.
Our mission is to empower individuals, businesses, and communities to embrace sustainable practices that protect our planet and ensure a brighter tomorrow for generations to come.
The function of Maximum Power Point Tracking (MPPT) in a solar inverter is to optimize the power output from the solar panels to the inverter. It continuously tracks and adjusts the operating points of the system to ensure it is drawing the maximum power possible. By doing so, MPPT greatly improves the performance and efficiency of the solar power system.
Diving deeper into ‘how does MPPT work in inverter’, imagine capturing every sunray on a cool morning and converting all that solar energy into electricity—we wouldn’t need any other power source, right? While that’s a dream scenario, what MPPT does come pretty close. MPPT optimizes the voltage at which panels operate, ensuring that even under less than perfect conditions (cloudy skies, dusk, or dawn), the system performance remains at peak. Now, that’s an ally we need in our fight for sustainability, isn’t it?
The power output from a solar cell is defined by its IV (Current-Voltage) curve, which essentially tells us how the current output from a module changes with changing voltage. Now imagine this curve like a hilly landscape, and the maximum power point like the highest peak in that landscape. The MPPT in your inverter is like an expert guide, always keeping your system at that peak—even when it shifts with clouds covering the sun.
While we have our expert guide (MPPT) to find the maximum power point, it’s not always a straightforward hike. Several external factors like variations in light intensity, ambient temperature, and even the age of the solar panels can change the location of this maximum point. But, MPPT is always on duty, adjusting and readjusting to ensure you’re still receiving the maximum power output.
Let’s picture the function of an MPPT in a solar inverter as a savvy financial manager. By constantly adjusting for maximum power point, it ensures you get the most power at any given time, just like a good manager would guarantee the best returns on your investment. That means, just like how an investment manager usually keeps an eye on stock markets, MPPT keeps an eye on sawing voltage levels, temperature changes, light conditions, and ensures your battery is charged optimally.
Linking this into our journey metaphor, a single MPPT is like having an expert guide lead you through an uphill but straightforward path, efficiently. Dual MPPT, on the other hand, is akin to having two guides that can lead you up two peaks simultaneously. Essentially, if you have panels facing in different directions or at different inclinations, dual MPPT can manage the output from each set to get the best overall performance.
We’ve talked about Single and Dual MPPT, but the world of solar energy doesn’t stand still, and neither should your understanding. That brings us to the “all-terrain vehicles” of the solar power world – the Multi MPPT inverters. They take our efficient hiking guide to the extreme, allowing for multiple ‘guides’ to lead the way up different ‘hills’ on our IV curve, navigating changes in shading, orientation, or even panel type.
You might have also heard of another solar inverter technology called Pulse Width Modulation (PWM). But which one to choose? It’s like deciding between an automatic versus manual car. While both get the job done, an automatic (MPPT) might just make your life a tad easier, especially when dealing with complex terrains or climates.
Linking MPPT with battery power like 12V, 24V, or 48V, is like matching your car engine to the fuel you use. Just like you wouldn’t use diesel with a petrol engine, you wouldn’t use a 48V battery with a 12V solar inverter. Making the right ‘match’ guarantees you harness the maximum power from your solar installation.
By now, if your mind is swimming in terms like ‘maximum power point’, ‘IV curve’, or ‘PWM’, let''s simplify all this solar talk. In essence, MPPT is your personal aid in your solar power system that ensures you are getting the highest possible power from your solar panels.
As we delve further into the world of renewable energy sources, understanding the technical aspects becomes paramount. I hope functions like MPPT, solar inverters, and their intricacies don’t puzzle you anymore.
Harnessing solar power is like climbing on a mountain—the view (or in this case, the energy yield) gets better as you reach higher. MPPT is your skilled climbing partner that ensures you’re always on the best route. So, if someone asks you, ‘what is the function of MPPT in solar inverter,’ you’ll know that it’s not just a technical component; it’s an essential energy-maximizing tool.
Maximum power point tracking (MPPT),[1][2] or sometimes just power point tracking (PPT),[3][4] is a technique used with variable power sources to maximize energy extraction as conditions vary.[5] The technique is most commonly used with photovoltaic (PV) solar systems but can also be used with wind turbines, optical power transmission and thermophotovoltaics.
Solar cells'' non-linear relationship between temperature and total resistance can be analyzed based on the Current-voltage (I-V) curve and the power-voltage (P-V) curves.[7][8] MPPT samples cell output and applies the proper resistance (load) to obtain maximum power.[9] MPPT devices are typically integrated into an electric power converter system that provides voltage or current conversion, filtering, and regulation for driving various loads, including power grids, batteries, or motors. Solar inverters convert DC power to AC power and may incorporate MPPT.
The power at the MPP (Pmpp) is the product of the MPP voltage (Vmpp) and MPP current (Impp).
In general, the P-V curve of a partially shaded solar array can have multiple peaks, and some algorithms can get stuck in a local maximum rather than the global maximum of the curve.[10]
Photovoltaic cells have a complex relationship between their operating environment and the power they produce. The nonlinear I-V curve characteristic of a given cell in specific temperature and insolation conditions can be functionally characterized by a fill factor (FF). Fill factor is defined as the ratio of the maximum power from the cell to the product of open circuit voltage Voc and short-circuit current Isc. Tabulated data is often used to estimate the maximum power that a cell can provide with an optimal load under given conditions:
For most purposes, FF, Voc, and Isc are enough information to give a useful approximate view of the cell''s electrical behavior under typical conditions.
For any given set of conditions, cells have a single operating point where the values of the current (I) and voltage (V) of the cell allow maximum power output.[11] These values correspond to a particular load resistance, which is equal to V / I as specified by Ohm''s law. The power P is given by P=V I.
