MPPT is a techinque we implemented to get the maximum possible power from a solar panel. When trying to characterize the output of a solar panel mathematically, it can be represented by an IV-Curve (shown below). The equation for Power is P = IV. Where I is the Current, V is the Voltage, and P is the possible output Power. Each point on the curve is a possible combination for output power and our goal is to find the best combination to obtain maximum power. In simple terms, we are trying to get the biggest rectangle to fit under this so called IV-Curve, the bigger rectangle we can fit, the more power we get. Below are graphs to help you understand the idea better. This is a comparison between inverters with and without MPPT on an 85W solar panel. Please note that different solar panels will have slightly different IV-Curves. No Tracking Vs Tracking Figure 1 No MPPT, with voltage fixed 17.5V P = 17.5V x 4.6A = 80.5W Figure 2 With MPPT, amount of current and voltage to draw are calculated P = 17V x 4.95A = 84.15W As we can see, Figure 2 is able to 84.15W with MPPT while in Figure 1, we can only get 80.5W. This is 4.5% increase in power output. Why do we care? Because solar panels are still quite expensive these days, and the increased power output will directly affect our return on investment (ROI). In addition, depending on weather, time of the day and amount of solar irradiation the panel receives, the IV curve will move along the Y-axis to reflect the possible increase / decrease in potential power output, and cause the maximum power point to shift along as well. Coming up are illustrations to visualize this idea. IV-Curves Under different weather conditions Figure 3. Sunny, Clear Sky days in Summer 600 ~ 1000 W/m2 No MPPT MPPT Power 80.5W 84.15W Color Red & Yellow Yellow& Green Percent N/A +4.5% Figure 4.

Cloudy or fog days, dawn or dusk in Summer 100 ~ 300 W/m2 No MPPT MPPT Power 5.25W 14.25W Color Red & Yellow Yellow& Green Percent N/A +171% Figure 3 - 5 illustrate the power gain in different weather condition with MPPT compare to a non-tracking inverter that locks voltage at 17.5V. While 17.5V is randomly chosen, it does show what would happen in real life when there is not MPPT. Studies have shown, by making use of MPPT, there will be an average of 30% increase in power production. Since the maximum power point is a variable, we have implemented a tracking algorithm that utilizes the micro processing power of our inverter to calculate the optimum voltage and current to maximize our energy harvest. Increased Power Rating: In 2008, when we designed the first generation inverter, what we had in mind was an inexpensive device to allow the public to have a chance to test out renewable energy production and promote the green movement at an affordable price range. As people's environmental awareness increased over the years, the demand for bigger systems also increase. Therefore, once again, the power of this inverter has increased to accomodate market demand.
