Twerd PS100-WT 3kW Wind Inverter (1-phase, on-grid)

The Twerd PS100-WT is a single-phase inverter designed for small wind power plants equipped with permanent magnet synchronous generators (PMSG). With a rated power of 3 kW, the device offers 97% efficiency and operates in on-grid mode, while supporting off-grid systems when equipped with an optional module.

The Twerd PS100-WT wind inverter provides a rated power of 3000 W and works with a 230 V single-phase grid. The device utilizes a 16-point MPPT curve, which depends on the load and frequency of the connected turbine. The inverter features dedicated terminals for connecting dump load resistors to prevent turbine overspeed, as well as a built-in tail control system. System performance monitoring is handled via integrated Modbus RTU and Ethernet interfaces.

Key features

• Maximum efficiency of 97% and temporary overload capacity of 110%.
• Equipped with 3 relay outputs and 5 digital inputs.
• Direct compatibility with NPN OC anemometers for precise wind speed monitoring.
• Built-in hardware protection features, including anti-islanding, short-circuit, overvoltage, undervoltage, and thermal protection.
• Sealed enclosure with an IP 65 protection rating for operation in harsh environments.
