Solar Grid Tie Inverter/1000w SUN-1000G


User Instructions for Model SUN-1000G

u  ‘SGPV’ (Small Grid Tie Photovoltaic System)

l  The only plug and play small grid tie photovoltaic system

l  The stackable small grid tie photovoltaic system 



■ Super junction MOSFET integrated with 97.7% Max. efficiency.
■ Wide MPPT voltage range and low minimum MPPT voltage for flexible configuration.
■ Transformerless design for lower cost and compact size.
■ IP65 and fan-less for longer-term reliability.
■ Ethernet/ Wi-Fi communication interface.
■ Integrated Web Server for local and internet monitoring. 




The individual system of SGPV is shown in Figure 1. Installing the solar panel of the SGPV at a suitable location that sunshine can irradiate on it, connecting the cables of the solar panel to the DC input terminals of the small grid tie inverter of the SGPV, inserting the plug of the inverter into the socket of the home grid. After this, when the sun shines, the SGPV will convert the solar energy to the home grid.

                                                                                                                       Figure 1    A SGPV

SGPV can be stackable, and all SGPVs are independent each other. The total power converting to the grid is the total power of all SGPVs. The installation of each SGPV is same. Connecting large quantity of SGPV to the grid, this will construct high-power grid-tie system

u  Operation Procedures

1, Connect the Solar Panel or Wind Turbine’s DC supply cables to the DC input terminal of the inverter, be sure that the polarity is correct. Recommended DC input cable size for maximum output is 8AWG or cables that can handle more than 40A. Optimal length would be less than 8m, longer cables will experience higher voltage drop. The range of output power of Solar Panel or Wind Turbine is 20W~1000W.

2, Connect the supplied AC power cord to the inverter and plug it to a home wall socket.

3, The 3 green LED indicators will start to cycle from left to right when the grid and DC supply is detected. This indicates the inverter is operating under normal condition. The rate of the cycling is according to how much power is being output from the solar panels or the wind turbine. The more big output power is, the more fast the rate is. If there is no AC grid detected, the red LED will be on, the inverter will not put out power, this is called “Island Protection”.
