Twerd PS300-WT Wind Inverter (10 kW, 3-Phase, On-Grid)

The three-phase, transformerless Twerd PS300-WT 10 kW inverter is designed for on-grid operation in micro wind installations. The device works with permanent magnet synchronous generators and enables autonomous operation with the power grid.

The Twerd PS300-WT inverter is a three-phase, transformerless device designed for on-grid installations with wind turbines. The generator load control system is based on a user-defined 16-point input current versus frequency curve. Alternatively, the load current can be set directly via the MODBUS communication protocol. Built-in internal relays allow control of braking resistors.

Key features

• Designed for permanent magnet synchronous generators in on-grid systems.
• Integrated protection against generator overspeed and islanding.
• Communication via Ethernet and RS-485 interfaces.
• Internal relay for braking resistor control (30 A, AC1).
• High environmental resistance thanks to the IP65 enclosure.
