SUN-2000G Solar Grid Tied Inverter/2000w Preface

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 cable with no extra equipment. The installation is very convenient and reliable.

 We call the system combining with small solar grid tie power inverter and solar panels as ‘SGPV’. The system includes solar panels and small type grid tie power inverter. 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 outlet at home, when this line run by the conventional electric network. The small grid tie monitors the volume, frequency and phase of the home grid, then produce a pure sine wave 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.


SUN-2000G Solar Grid Tied Inverter/2000w Advantage

There are many advantages of SGPV compare with the traditional grid tie system.


2. Free combination - SGPV can be used as a separate grid tie system and can be setup as a large solar array with many of them. The quantity of SGPV in the array is just as you require. If you are planning to install a grid-tie PV system, in a general way, the solar array and inverter need to be carefully matched to ensure that the inverter’s voltage and power limits are not exceeded. When you want to increase more solar panels, and if the total power of the solar panels exceeds the allocation grid inverter, it is necessary to increase the cost of a grid inverter.

Combination of SGPV does not interact. If the performance of a piece of solar panels in the system degrades, this just effects this piece itself, will not affect other SGPV in the system.

Improving the efficiency of the entire solar power system.. 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.

3. 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, but this will not increase the power consumption of the entire system.

SUN-2000G Solar Grid Tied Inverter/2000w  Installation

The individual system of SGPV is shown in PIC3. 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.

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


SUN-2000G Solar Grid Tied Inverter/2000w Operation Procedures


1Connect 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.
