Description  :

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 panelscan 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.

Advantage  :

1. Low cost and easy installation - SGPV can make full use of all types of buildings’ surface that face to the sun in the city as well as fast and easy installation of solar modules and grid tie inverter. It just needs very low maintenance costs.

Installing Grid Tie Power System to Three Phases Utility Grid

When the Capacity of Gird Tie Power System is larger, intall all the power system to one phase of the utility grid is not reasonable, maybe this will cause unbanlance of the three phase of the utility grid.

In this section, we will explain how to install Sunshine Power System to three phases utility grid seperately in order to balance the fed power.

Display Instruction:

The Inverter display can show many information,The main interface of the display and the icons explainations are show above.

Set Menu: Choose the set menu icon on the main screen interface,click the confirm button to enter into the interface show below,In this interface,can set the LCD backlight always on or auto turn off backlight after 3 minutes no action.

The inverter also integrate with internal limiter and external limiter function which can prevent excess power from going to the public grid.Select the internal limiter mode,inverter will work under limiter mode,output power of the inverter will be determined by load power.Select the external limiter mode,inverter need a external limiter module working with it.For more details about the limiter function,pls contact supplier.
