s most technologically advanced inverter for
use in utility-interactive applications. This manual details the safe installation and opera-
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.
