For wind turbines — NPP "VEL"

GridWind 20kW 550VAC 220/380VAC inverter

Purpose:

The inverter converts the variable-frequency AC voltage produced by a wind turbine into 220/380 V, 50 Hz AC and exports the turbine's power to the public grid
The inverter has an intelligent control system that sets the amount of power exported to the grid according to the frequency of the AC voltage produced by the turbine (which depends on the turbine's rotational speed)

Distinctive features:

Nominal output power — 20 kW.
Peak output power — 30 kW.
Silent, high-efficiency operation
A high-efficiency combined liquid and air cooling system with three cooling levels and five operating modes.
A control panel with a blue-backlit LCD showing the inverter's operating parameters (turbine voltage and frequency, grid voltages and currents, and the power exported to the grid).
Six LED indicators show the inverter's status.
Audible warning signals indicating the various operating modes, faults and system problems.
Operating modes, the monitored turbine and grid parameters, and the power-take-off table can all be programmed from the control panel.
Inverter run/fail signalling relay (option).
Low standby consumption (under 30 W).
Automatic overload and over-temperature protection
