Product information

Description

The TWERD PS300-WT is a high-performance 3-phase on-grid inverter designed for 10 kW solar power systems. This grid-tied solar inverter efficiently converts direct current generated by photovoltaic panels into alternating current, which is then synchronized with the public electrical network. Engineered for reliability and consistent energy production, it serves as a core component for residential and light-commercial solar installations, ensuring optimal power conversion and grid stability.

Advantages

This inverter offers robust performance through its 3-phase architecture, which provides balanced power distribution across the electrical grid. Its design focuses on high conversion efficiency, minimizing energy losses during the transformation process. The unit is built to withstand standard operational demands, featuring integrated protection mechanisms that safeguard the system against common electrical faults. Its compact and functional design allows for straightforward integration into existing solar setups, promoting long-term operational reliability and ease of maintenance.

Suitable for

  • Residential solar power systems requiring 10 kW capacity
  • Light-commercial grid-tied photovoltaic installations
  • Systems utilizing a single-MPPT solar array configuration
  • Projects aiming for efficient grid synchronization and energy feed-in

This inverter may not be suitable for off-grid systems that require battery storage, as it is specifically engineered for grid-tied operation. Additionally, it is not designed for installations involving complex multi-string arrays that require independent MPPT tracking for each string.

Key specifications

  • Rated output power: 10 kW
  • System type: 3-phase on-grid
  • MPPT configuration: Single MPPT
  • Application: Grid-tied solar systems
  • Output: AC power for public network synchronization

Installation should be performed by a qualified professional to ensure compliance with local electrical codes and safety standards. The inverter must be mounted in a well-ventilated area, protected from direct environmental exposure, and connected to the solar array and the grid according to the provided technical documentation. Once installed, the system automatically manages the conversion process and grid synchronization.

What to consider before purchase

  • Verify that your solar array configuration is compatible with a single-MPPT input
  • Ensure your local grid regulations permit 3-phase grid-tied solar connections
  • Confirm that the 10 kW output capacity matches your energy production requirements
  • Check the available installation space for proper ventilation and maintenance access

Usage recommendations

Regularly monitor the inverter status via the integrated interface to ensure optimal performance and check for any system alerts. Keep the cooling vents clear of dust and debris to maintain efficient thermal management throughout the year.
