What is 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. Electrical Specifications – Output. Nominal AC Output Power. AC output voltage range. Total harmonic Distortion (THD).

Non- Reusable Power being consumed today. Reusable Power being generated for a better tomorrow and a brighter future. 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. Figure 1: AC Power. Figure 2: DC Input. Install in a low humidity and well-ventilated area. Remove all flammable objects. Connect the Solar Panel, Battery or Wind Turbine’s DC supply cables to the DC input terminal of the inverter as shown in Figure 2. Wind Turbine installations will require respective charge controllers and dump loads. Connect the inverter to a wall socket with the supplied AC Power Cord as shown in Figure 1. Pay close attention to the polarity of your DC input. Connecting incorrectly might blow the fuse. In such case the inverter will make a buzz sound whenever power is connected and the fuse will need to be replaced. Improper installation, accident, misuse. Any unauthorized disassembly, repair, or modification. NO OPERATING COST GENERATES ELECTRICITY FROM THE ABUNDANT RESOURCE – SOLAR & WIND.
