TWO Green ergyStar MPPT. 400W Grid Power 2. For Solar & Wind Hybrid Systems. MPPT to Enhance Power Output by 30%! What is a Micro Grid-Tie Inverter? First, we should know what a Grid-Tie Inverter is. A Grid-Tie Inverter is a device that that can transform DC electricity (ie: Solar Panels, Wind Turbine, Battery Storage) into AC power that can be directly injected into your utility’s electricity network (the power grid). As of today, most inverters available in the market are in the high output (1000W 5000W) category. Their prices ranges in the thousand’s range and it is just too much of an up front cost for anyone interested in green energy generation. In addition, because of the high output, a certified electrician will need to be hired to install the equipments and connect the cables. Ever since we invented the first generation of the Micro Grid Tie Inverters, connecting to the grid has never been this easy and affordable. This is the perfect start up solution for anyone interested in green energy generation as it is affordable and maintenance free. In addition, our inverters are stackable ; meaning multiple unit of these devices can be connected in parallel to generate a higher output. It is up to us. Up to this generation. To lead mankind into a greener future. Non- Reusable Power being consumed today. Reusable Power being generated for a better tomorrow and a brighter future. What’s New in the MPPT 2nd Generation? So you ask, What’s new in this MPPT revision of the 2nd Generation Inverter? Well, the Maximum Power Point Tracking (MPPT) algorthim has been improved to match our 3rd generation inverters. Aside from that, there are number of upgrades in performance, safety and display that are not available in the first generation or other inverters in the market. We will use our Enviro-Techs SSI-200W first generation inverter as the base model for comparison. Here are the high lights. Maximum Power Point Tracking (MPPT). What is Maximum Power Point Tracking (MPPT)? 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. Sunny, Clear Sky days in Summer 600 1000 W/m2. Scattered Clouds or Partly Cloudy days in Summer 300 600 W/m2. Cloudy or fog days, dawn or dusk in Summer 100 300 W/m2. 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. 152 x 143 x 57 mm. 163 x 154 x 57 mm. 400W, 60% enhanced in Power Output – 38.5% better in Space Utilization. 51% better in Weight Reduction with.

Unique and intuitive display design – LED cycling in circular formation – Represent electric meter spinning backward and power is being output to the grid – Smooth motion. 800W MPPT Grid Tie Inverter. For Solar & Wind Hybrid Systems. To Enhance Power Output by 30%! Of all the different kinds of renewable energy available today, solar and wind are the two most popular ones favored by homeowners due to their. Easy implementation and wide range of suitable sites. However, these green energy sources do not come with a plug to connect to a wall socket (the grid). Even if they do, there are different parameters for each type of renewable energy and interconnecting with the grid would present a challenge. Fortunately, grid-tie inverters have been invented to solve this interconnection problem. What is grid-tie inverter? A Grid-Tie Inverter is a device that that can transform 12V DC electricity i. Solar Panels, Wind Turbine, Battery Storage into 120-240V AC power that can be directly injected into your utility’s electricity network (the power grid). However, the down side is, most inverters available in the market today are in the high output (3000W 8000W) category. Their prices range in the thousands and it is just too much of an upfront cost for anyone interested in green energy generation. In addition, because of the high output, a certified electrician will need to be hired to install the equipments and connect the cables. I would also like to DIY to cut down on cost and have a project that I would be proud to work on… Isn’t there an. Way to do this? With our latest developed micro grid-tie inverter Grid Power 3 feature the popular plug and play function, you will be connecting your renewable energy sources into the grid and join the green movement in no time. A Greener future awaits. What’s New in the 3rd Generation? So you ask, What’s new in this third generation? Well, by reaching the 3rd generation, we have again improved the power output by incorporating Maximum Power Point Tracking (MPPT) technology to harvest more solar energy. The inverter has also utilized better surge protection components to shield against voltage spikes and energy surges. In addition, this inverter will work with our SolarWind Hybrid RX charge controller to allow wind energy input. Here are the high lights: Maximum Power Point Tracking (MPPT).

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.
