300 Watt MPPT Power Grid Tie Inverter for Solar Panel Wind Turbine

Green ergyStar 300W MPPT Grid Tie Inverter For Solar & Wind Hybrid Systems MPPT to Enhance Power Output by 30%! Brand new~ Environment friendly~ What is a Grid-Tie Inverter?
In a nutshell, 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).
While high output (1000W ~ 5000W) inverters are available in the market, their prices ranges in the thousand's range 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.
With the invention of the SSI-200W Grid-Tie Inverter, connecting to the grid has never been this easy
and affordable
. All that has to be done is connect your DC Sources (Solar Panels or Wind Turbine) to the SSI-200W, and use the included cable (North American standard) to connect to any home AC electrical outlet, and you are feeding/selling green energy back into the grid at a premium rate
(subject to local policies). This is the perfect start up solution for anyone interested in green energy generation as it is affordable and maintenance free.
In addition, the SSI-200W is stackable
; meaning multiple unit of this device can be connected in parallel
to generate a higher output. Electrical Specifications - Output:

Reusable Power being generated for a better tomorrow and a brighter future What is 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

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. Installation:
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.

Warning! 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.
