1、This inverter is the most technologically advanced inverter in the world and can be used for utility interactive applications. 2、The integrated system can collect energy to the greatest extent, improve system reliability, and facilitate installation and management. 3、Small wind inverters can obtain wind energy from wind turbines and can be connected to the grid through their output cables without additional equipment. 4、This inverter can be connected to any socket of the household utility grid. 5、Small size, easy to carry and store, convenient to use and with good performance. 1 x Inverter1 x Unloading Resistance Kit (resistor, 2 wires, 2 mounting brackets) 1 x Wifi Kit(Wifi module, 2 screws, connecting wire)1 x LIMTER1 x Power Cord1 x User Manual  Item Type: InverterModel: 2000G2WAL-HCircuit Topology: Half bridgeOutput Voltage Waveform: Sine waveInput Voltage Range: 45-90VDC (V)Output Voltage: 220 (V)Output Power: 2000 (W)Inverter Efficiency: 95%Voltage Regulation Rate: 95%Load Regulation Rate: 95%How to Use: Use the wiring according to the user manual step diagram.Features: 1. The inverter can be connected to any socket of the home public grid. 2. The small grid-connected inverter monitors the volume, frequency and phase of the household utility grid, and then generates a pure sine wave alternating current with the same frequency and phase as the grid, and its volume is higher than the grid, and then according to the current-controlled PWM to control The output power to the grid. 3. The small grid-connected inverter only cuts off power when the home grid is turned on. When the wind generator rotates, the voltage output is within the rated input voltage range of the inverter, the wind generator will generate electricity and the grid-connected inverter Will change the power of the wind turbine to the home grid. 4. When the total power of the electrical equipment used in the house is greater than the output power of the inverter, the power from the inverter will be consumed in the house, which will reduce the speed of the power meter, otherwise, the total use of the output difference device The inverter power between the power will be output from the house to the external grid.
