VL series Solar TX 3P/3P 20KW

Built-in with isolation transformer, VL series Solar TX purifies input power to connected devices. It can be operated in three different operation modes, on-grid, off-grid and grid-tie with backup, depending on power requirements. InfiniSolar TX is a flexible and smart hybrid inverter which utilizes solar power, AC utility, and battery power source to supply continuous power. Besides, it can set power usage priority as self-consumption for maximizing your benefit.

Main Features

  • Pure sine wave output
  • Self-consumption and Feed-in to the grid
  • Programmable supply priority for PV, Battery or Grid
  • True galvanic isolation transformer design
  • User-adjustable charging current
  • Programmable multiple operation modes: Grid-tie, off-grid and gridtie with backup
  • Built-in timer for various mode of on/off operation
  • Multiple communication for USB, RS-232, Modbus and SNMP
  • Monitoring software for real-time status display and control
