Product Introduction.
This Grid Tie Power Inverter is the world’s most technologically advanced inverter for use in utility-interactive applications. This integrated system maximizes energy harvest, increases system reliability, and implifies design, installation and management. The small type solar grid tie power inverter can obtain the solar energy from solar panel, and can tie to the grid through its output cables with no extra equipment. The installation is very convenient and reliable.
We call the system combining with small solar grid tie inverter and solar panels as ‘SGPV’. The system includes solar panels and small type grid tie inverter and installation kit. Solar panels can be mono silicon, polygon silicon, non-crystal film or any other material that can transform solar energy to electric energy. The power of grid tie inverter should be matched to the power of solar panels connected. So the power of SGPV is defined by its solar panels, it can be standardization according to the actual using.
The inverter can be connected to any outlets of utility grid at house. The small grid tie inverter monitors the volume, frequency and phase of the home utility grid, then produce pure sine wave AC power that the frequency and phase are as same as the grid's, and the volume is a bit higher than the grid's, then according to the current controlled PWM, to control the output power to the grid. The small grid tie inverter just puts out power when the home grid is on. When the sun shines, the PV panel will produces DC voltage, and the grid tie inverter will change the DC voltage to AC voltage and puts out power to the home grid. When the total power of electric apparatus that are using in the house is larger than the output power of the inverters, these power from the inverters will be consumed in the house, this will slow down the power meter, otherwise, the difference of the output power of the inverter between the total used power of the apparatus will go out from the house to the out grid.
Why we produced the GRID TIE INVERTER WITH LIMITER?
It is in response to the overwhelming clamor from our customers for a product that can control the amount of power that the grid tie inverters (GTI) can generate so that the amount of excess power produced by the solar panels are reduced to insignificant levels, if not eliminated --- because in some countries,the producer pays for the excess power it gives to the distribution grid. This is because the electric power meters (the one provided by the electricity provider in the area) are not aware of the direction of power flow. In other words it only adds even if power is exported to the grid, thus, the consumers will be charged for power even if it is given to the grid, and this is the problem.
This is the 2nd generation grid tie inverter with limiter. With the 2nd generation GTIL,we integrated the limit function inside the GTI-We call this internal limiter.In this way, No additional limiter module is needed,reduced customerrsquos cost,more easier for installation.But in case customer install inverter far away from the main circuit breaker,we also enable the 2nd GTIL work with stand-alone limiter,we call this-external limiter. For sure,the inverter can work under normal Grid tie-no limit mode,just set on the nice LCD and save your setting. New upgraded firmware enable battery or solar limiter current and power model. User can set the maximum output power of inverter , this can make the inverter work at cooler contition as user want and extend the lifespan of the inverter. User can set kick in/off voltage of the inverter which can flexible using with battery bank depend on users mind and can prevent battery bank from over discharged.

Installation Instructions
Installing Sunshine Grid Tie Power System involves several key steps:1. Considering the total capacity of the grid tie power system that you need.
2. Choosing applicable wind turbine for Sunshine Grid Tie Inverter.
3. Selecting accessory for installation of the Grid Tie Power System .
4. Selecting correct model of Sunshine Grid Tie Inverter.
5. Installing wind turbine to suitable place.
6. Installing Sunshine Grid Tie Inverter to suitable place.
7. Connecting Sunshine Grid Tie Power System with cables and connectors.
8. Grounding the system.
Example of Installation of 1KW grid tie power system.
In order to explain the installing operation, we assume that there is a house that the usualelectricity consumption is about 5KWH per day, and the wind is high enough to drive the
wind turbine.1, Considering the total capacity of the grid tie power system that you need.As we stated at Step1, we can get a result that a 1kW Sunshine Grid Tie Power System is suitable for this house, so we will establish a 1KW gird tie power system step by step, we also assume that we will install the system in the house where the utility grid is 230V/50Hz.2, Choosing Applicable Wind Turbine. If you purchased a wind turbine, it is DC output type, this means there is already a rectfier has been integrated in the wind turbine, or there is a wind turbine controller that can tranform AC to DC connected with the wind turbine.3, Choosing connecting cables and connectors that will be connected between wind turbine and gird tie inverter. If the wind turbine is DC output type, then you should choose AWG 6 connecting cables, and if the wind turbine is AC output type, then you should choose AWG 8 connecting cables according to the table 3. When you choose connectors, the connectors must can hold the cuurent above the Imax.2, Choosing Applicable Wind Turbine. If you purchased a wind turbine, it is DC output type, this means there is already a rectfier has been integrated in the wind turbine, or there is a wind turbine controller that can tranform AC to DC connected with the wind turbine. Till now, you can follow these steps to complete the installation of wind grid-tie system.
*1KW wind turbine.grid tie invereter connected with AC output type of wind turbine.
*2KW wind turbine. Connecting two MSC-1000G2-WAL with a max. power is 2KW wind turbine.
*Three Phases Grid Tie Power System. For example, installing a 3KW grid tie power system to three phase utility grid.
The diagram is shown in Fig. 8, we seperate 3KW power sytem to three power system units, every unit has 1KW power. Connecting every system unit to different phase, this can balance all grid tie power to three phases of the utility grid.
Follow this way, you can install more large grid tie power system to three phases, just seperate the whole power system to three equal power system units.
