INV Series

INV Series

INV Series inverters offer high-performance and intelligent energy solutions, equipped with advanced DSP (Digital Signal Processor) control and SPWM technology. While guaranteeing stable voltage and frequency for your critical loads thanks to its pure sine wave output, it provides a continuous, reliable power supply to your system with its built-in bypass switch and superior overload capacity. Offering flexibility with AC-priority or DC-priority operating modes as needed, the INV Series stands out with its design that allows automatic bypass transfer during maintenance processes without interrupting the load. Optimized especially for sites requiring continuous operation, such as unmanned communication stations, this series maximizes your operational efficiency through its automatic fault recovery function, remote monitoring capability via network, and dry contact outputs that provide DC/AC fault tracking.

  • With DSP control, the INV Series inverter is an intelligent model product offering advantages of good design and reliability.
  • The INV series inverter features SPWM technology, providing pure sine wave output with stable voltage and frequency.
  • The INV series inverter has a well-matched, built-in bypass switch and high overload capability for a reliable and continuous power supply.
  • The INV series inverter can be of AC power type or DC power type.
    • AC power type means that the mains supply is the main source when the mains are normal; the inverter enters operation mode when the mains are off.
    • DC power type means that the inverter power supply is the main source when the mains are normal; when the inverter power is off, it automatically switches to operation mode from the mains.
  • With its excellent design, the INV series inverter can automatically switch to bypass mode during operation, making battery maintenance and replacement easy without affecting the load power supply.
  • In case of high/low battery voltage or overload, the overload warning will shut down the output; when the battery voltage returns to normal, the battery voltage will recover; the power supply output will automatically recover within 50 seconds after overload shutdown. This function is very suitable for communication stations where no one is on duty.
  • The INV series inverter can support network communication systems; the power operating status can be monitored by supervision software.
  • The INV series inverter provides two dry contacts that can be used for DC input fault control and AC output problem warning.
