Features

  • Advanced Digital Control: Uses DSP, MCU, and DDC real-time processing all-digital control technology for precise and stable operation.
  • High-performance Inverter Technology: IGBT inverter technology and high-frequency PWM technology ensure efficient power conversion and strong load adaptability.
  • Comprehensive Protection: Full protection against AC input over/undervoltage, output over/undervoltage, overload, short circuit, over-temperature, battery overcharge, and undervoltage warning.
  • Pure Sine Wave Output: Delivers clean three-phase power with low harmonic distortion (linear load <3%, non-linear load <5%), compatible with all types of loads.
  • 7-inch Touch Screen Interface: Intuitive 7-inch touch screen digital display for real-time monitoring and parameter setting.
  • Flexible Communication: Supports RS232, RS485, and optional network remote monitoring for convenient system management.
  • Strong Load Capacity: 3:1 peak current ratio and robust overload resistance, suitable for heavy industrial and mixed loads.
  • Wide Environmental Adaptability: Operates reliably in 0°C–40°C, <95% non-condensing humidity, and up to 5000m altitude (with derating above 1000m).
  • Low Noise Operation: <58dB noise at 1m distance, suitable for noise-sensitive environments.

Application

  • 🏭 Industrial & Factory Power: Provides stable three-phase power for manufacturing plants, processing facilities, and heavy industrial equipment.
  • 🏨 Large Commercial Buildings: Powers hotels, villas, shopping malls, and office complexes with reliable backup or off-grid energy.
  • 🏠 Residential & Community Systems: Delivers high-capacity power for large residential communities and remote villages.
  • 🚢 Marine & Island Energy: Ensures uninterrupted power for ships, offshore platforms, and isolated island installations.
  • 🐑 Agricultural & Farm Use: Supports irrigation systems, farm machinery, and livestock facilities in rural areas.
  • 🔌 No-Electricity Zones: Provides reliable power for remote construction sites, mining operations, and off-grid industrial projects.
