applications. This manual details the safe installation and operation of the Sunshine Grid Tie Inverter.
This integrated system maximizes energy harvest, increases system reliability, and simplifies design, installation, and management.
The small type of solar grid tie power inverter can obtain solar energy from the solar panel and 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 convert solar energy into electric energy. The power of the 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 the utility grid at the house. The small grid tie inverter monitors the voltage, frequency, and phase of the home utility grid, producing pure sine wave AC power that the frequency and phase are the same as the grids. The voltage is a bit higher than the grids, then according to the current-controlled PWM, to control the output power to the grid. The small grid tie inverter puts out power when the home grid is on. When the sun shines, the PV panel will produce 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 the electric apparatus that are using in the house is larger than the output power of the inverters, this 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.
