Product information

Description

The TWERD PS300-WT is a high-performance 3-phase on-grid inverter engineered to convert direct current from renewable sources into alternating current for grid synchronization. With a rated output of 3 kW and a dedicated 1500 W turbine input, this device is designed to integrate wind or solar energy systems into the local electrical grid efficiently. It ensures stable power delivery and reliable operation for residential and small commercial energy setups.

Advantages

This inverter offers robust conversion efficiency and seamless grid integration, allowing users to maximize the utilization of renewable energy. Its 3-phase architecture provides balanced power distribution, which is essential for modern electrical installations. The dedicated turbine input allows for versatile energy harvesting, making it a flexible solution for hybrid renewable energy projects. The unit is built for durability and consistent performance, ensuring that energy export is managed effectively while maintaining grid compliance.

Suitable for

  • Residential renewable energy systems
  • Small commercial grid-tied installations
  • Hybrid wind and solar power setups
  • Grid-synchronized energy export

This inverter may not be suitable for off-grid applications that require battery storage or standalone power generation, as it is specifically designed for grid-tied operation. It is also not intended for high-power industrial loads exceeding its 3 kW rated capacity.

Key specifications

  • Rated output power: 3 kW
  • Turbine input capacity: 1500 W
  • Grid connection: 3-phase
  • System type: On-grid

To use the TWERD PS300-WT, the device must be installed by a qualified electrician in accordance with local grid regulations. The DC inputs from the turbine or solar array are connected to the designated terminals, while the AC output is synchronized with the 3-phase grid connection. Once powered on, the inverter automatically manages the conversion process and monitors grid parameters to ensure safe and efficient energy export.

What to consider before purchase

  • Verify compatibility with your existing turbine or solar array specifications
  • Ensure your local grid supports 3-phase inverter connections
  • Confirm that the installation site meets environmental requirements for the device
  • Check local regulations regarding grid-tied energy export
For optimal performance and longevity, ensure the inverter is installed in a well-ventilated area protected from direct moisture and extreme temperatures, and perform regular inspections of all electrical connections.
