Overview of Solar Inverters: FIMER PVI-55.0/330.0 Series

Key Features

  • Power Range: From 55 kW to 300 kW using modular 55 kW blocks.
  • Efficiency: Up to 98% efficiency (for TL versions).
  • MPPT Channels: High-speed Maximum Power Point Tracking for optimized energy harvesting.
  • Input Voltage: Maximum DC input voltage of up to 1000 Vdc.
  • Flexibility: Suitable for large scale PV plants with reduced DC distribution losses.
  • Pre-configured Systems: Delivered pre-configured and pre-tested, reducing on-site wiring and testing.
  • Modularity: Each module operates independently, so a failure in one module does not affect others.
