Advantage of The Sunshine Grid Tie Power System There are many advantages of SGPV compare with the traditional grid tie power system. 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. 2.
Sunshine Grid Tie Inverter Installation Follow the instructions in this section to install Sunshine Grid Tie Inverters. WARNING: Before installing the Sunshine Grid Tie Inverter, read all instructions and cautionary markings in the user manual, on the Sunshine Grid Tie Inverter, and on the photovoltaic array.
Installation Procedure 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 solar panels 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 solar panels to suitable place. 6. Installing Sunshine Grid Tie Inverter to suitable place. 7.
Step2. Choosing applicable solar panels for Sunshine Grid Tie Inverter. Descripiton of Solar Panel Solar panel is an array of solar cells, it is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect. when exposed to light, it can generate and support an electric current without being attached to any external voltage source. Most solar panels consist of solar cells conected in serial.
Fig 2. I-V Curves Fig 3. Temperature Dependence of Isc, Voc, Pmax The I-V Curves shown in the Fig. 2 is a solar panel’s I-V curves that the power is 230W.
Selecting DC cables Before you connect the solar panels to inverter, suitable specification of cables should be selected. The selection of specifications of the cables is according to the total power of the solar panels and the connecting method of solar panels. You should calculate the maximum current that will transit through the cables, we mark it as Imax.

Step5. Installing Solar Panels to suitable place. Installing the solar panels of the SGPV to suitable location that sunshine can irradiate on them, there must have no shadow, the installation direction of the solar panels should be according to the geography position that the system will be installed, different position should has different installation direction, the principle is to get maximum irradation in all the year round.
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 real irradiation time is about 5 hours. 1, Considering the total capacity of the grid tie power system that you need.
4, Selecting correct model of Sunshine Grid Power Inverter. Because maybe there will be several methods of connecting solar panels to Sunshine Grid Tie Inverter, different connecting method maybe should use different model inverter. In this case, there are two connecting methods. With method 1, because all panels are connected in parallel, so we can know that the TVoc(total Voc of the solar panels) will be same as Voc of one panel, and the TVmp also is same as Vmp of one panel.
Comparing the connected method in Fig.4 and Fig5, we can see that method 2 is the good choice, because with method 1, the DC cables is more thick, so it is more expensive, and three pairs of connectors for parallel connecting plus three pairs of MC4 connectors should be used. But with method 2, the DC cables is thin, and just a pair of connectors for parallel connecting and a pair of MC4 connector should be used. Installing larger capacity of grid tie power system.
You can install any capacity of grid tie power system by stack small grid tie power systems. For example, if you want to install 12KW grid tie power system, there are many choices, you can stack six 2KW grid tie power systems, or twelve 1KW gird tie systems, or stack twenty-four 500W grid tie power systems, or stack fourty-eight 250W grid tie power system, even you can mix different capacity grid tie power systems to gain large capacity system.
Installing Sunshine 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.
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. Fllow 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.
