Sunshine Grid Tie Power Inverter is the world's most technologically advanced inverter for use in utility-interactive 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.

Advantage of The Sunshine Grid Tie Power System
There are many advantages of SGPV compare with the traditional grid tie power system.
Low cost and easy installation - SGPV can make full use of all types of buildings' surfaces that face 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.
Free combination - SGPV can be used as a separate grid tie system and set up as a large solar array with many of them. The quantity of SGPV in the array is just according to your desire.
Combination of SGPV does not interact - The traditional solar grid tie system is always connected with many panels. Those solar panels are connected in series, so the input voltage is very high, although, the traditional grid inverter has an MPPT feature (Maximum Power Point Tracking), but the maximum power point is according to the entire series in terms of solar panels array, if the performance of one piece of solar panels in the system, for some reason, such as leaves, bird droppings, dust, shadow, etc. and degrades, the performance of the entire solar power system will decrease.
SGPV system has no such disadvantage. If the performance of a piece of solar panels in the system degrades, this just effects one SGPV, will not affect other SGPV in the system.
Improving the efficiency of the entire solar power system - In a traditional grid tie system, many solar panels are connected in series, so the MPPT of the inverter is according to the total panels in series, not to every panel. Still, there is a difference between every panel, so not every panel is working at the maximum power, this will reduce the total power of these panels in series.
But SGPV has no such disadvantage. Because every inverter of SGPV has MPPT function, so every panel is working at the maximum power, this will increase the efficiency of the entire system.
Low power consumption - Most of the parts in the small grid tie inverter are digital ICs and low power MCU, so the power consumption of it is low. Though the quantity of grid tie inverters is increased, this will not increase the power consumption much of the entire system.
