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.

Installation Instructions
1.Installing Sunshine Grid Tie Power System involves several key steps
- Considering the total capacity of the grid tie power system that you need.2. Choosing applicable wind turbine for Sunshine Grid Tie Inverter.
- Selecting accessory for installation of the Grid Tie Power System.
- Selecting correct model of Sunshine Grid Tie Inverter.
- Installing wind turbine to suitable place.Installing Sunshine Grid Tie Inverter to suitable place.
- Connecting Sunshine Grid Tie Power System with cables and connectors.
- Grounding the system.
2.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 usual electricity consumption is about 5KWH per day, and the wind is high enough to drive the wind turbine.
- 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.
- 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.
- 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.
- Selecting Correct Model of MSC Grid Tie Inverter based on given specifications.
3.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.
Limit Function Connecting Instruction
Limit function for US split phase AC grid: The inverter should be connected to compensate 240V loads. Because the inverter will produce same value feed current at L1 and L2, and 240V loads also consume same value current at L1 and L2, so with the limit function of the inverter, the inverter will just produce power that is same as or less than 240V loads' power, there will be no extra countercurrent feeding to the AC grid. So if the 240V loads were connected at separate lines and not mixed with 120V loads, you can connect the inverter and clamp the limit sensor as picture4.
