LV On/Off Grid Hybrid Inverter



The Ultraverter LV On/Off Grid Low Voltage Hybrid Inverter is a cutting-edge hybrid solution engineered for both on-grid and off-grid solar applications. Operating on a safe low-voltage 48V battery system, it combines safety, reliability, and high performance in a compact design with superior power density. Its support for a solar PV/Inverter 1.3 DC/AC ratio offers greater system flexibility while optimizing investment. Designed for versatility, the Ultraverter enables unbalanced three-phase output and is ideal for residential, commercial, and industrial installations. It features multiple communication ports—including dual CAN ports for BMS and parallel connections, RS485 for BMS, RS232 for remote control, and a DRM port—ensuring seamless system integration and intelligent control. Key Features:

  • True 1/3-Phase Flexibility: 100% unbalanced output with each phase delivering up to 50% of rated power
  • Scalable Design: Parallel connection up to 6 units for 3 phase and 16 units for 1 phase >8kW for both on-grid and off-grid operation
  • AC Coupling Ready: Ideal for retrofitting into existing solar power systems
  • Battery Flexibility: Supports multiple battery units in parallel
  • High Power Handling: Charging/discharging Diesel Generator Integration and supports energy storage from genset sources
  • Safety First: 48V low voltage battery system with transformer isolation for enhanced protection
  • All-Weather Ready: IP66-rated for full water and dust resistance
  • Smart Energy Scheduling: "Time of Use" function with up to 6 programmable time segments
  • Remote Monitoring: Built-in Wi-Fi for real-time monitoring and control
  • The 5kW single phase unit features a fanless, low noise design for quiet operation
