product description
Performance characteristics of grid-connected wind turbine inverter
The main circuit adopts the DSP chip produced by American TI company, the German Infineon IGBT module, and the drive protection isJapan's Mitsubishi movement, the grid-connected output part uses an isolation transformer, which is safe and reliable.

Using SPWM pulsesWidth adjustment technology, pure sine wave output, automatic synchronous tracking with the grid, power factor close to 1, lowHigh current harmonic content, no pollution and no impact on the power grid.

Wind turbine input maximum power tracking technology (MPPT).

timeheThe fan power curve can be set, the default is 20 points, and the internal extension is 50 points.

7 inch color touch screenDisplay, the system operating data and fault information are clear at a glance, and the parameter setting is convenient.

Grid-connected inverter currentClosed-loop control, controllable and adjustable.

Wide input DC voltage range to meet different needsoccasion.

Frequency disturbance detection technology realizes anti-islanding control.

comprehensive power protection scheme andPerfect self-detection and protection functions, when the system fails, it will stop the grid-connected inverter.

The circuit structure isCompact structure, the highest efficiency is 98%.

Support RS485, WiFi, GPRS, Ethernet and other communication methods. you can monitor
Know the working status of the grid-connected wind power system in real time through PC or mobile phone, and you can also queryHistorical work status. The mobile terminal is compatible with Android and IOS. All data can be connected to the Internetthing.
Grid-connected wind turbine system
The grid-connected system of wind turbines is composed of wind turbines, grid-connected controllers, grid-connected inverters, metering devices, power supplies, etc.distribution system. Wind energy is converted to AC power by wind turbines and then converted to DC powerThe grid-connected controller converts electric energy into AC electric energy of the same frequencyThe grid-connected inverter is connected to the grid, and part of the electric energy is supplied to the local load. The remaining power is fed into thegrid.
