Heliac Solar Inverter

UTL Heliac solar inverter is one of the best inverter for home, which utilize both solar energy and grid power to charge the batteries. In first priority solar energy will run the load, charge battery and in second priority government electricity will be used. Heliac solar inverters are available from 850VA to 3500VA.

UTL Heliac smart PCU has the advance features like solar charge controller, multi colour LCD display, LED indication, maximum preference to solar, built in IT mode etc.

Buttons information

  • 1IT mode enables or disable – Press button three times to enable or disable the IT mode.
  • SMU and Tubular mode – Press button three times for on or off the SMU and tubular mode.
  • Power On or Off.
  • Boost Charging mode – Press this button three times for enable and disable the boost charging mode.
  • Grid charging and DC mode – Long press button for enable and disable Grid Charging and DC mode.

Special Features

  • Heliac solar inverter is preference to solar energy over the grid power. It gives first priority of charging to solar power over grid power. It means that when solar energy is available, the batteries will be charged through solar power whether grid power is available or not. It goes to grid power only when solar energy is not available. It helps in reducing electricity costs along with keeping the environment clean.
  • Heliac PCU can be operated with or without solar panels. The customer can use heliac solar inverter as a regular inverter without bothering about use of solar panel energy.
  • Heliac inverter has the intelligent feature to recognize the type of battery connected to it. It is auto adjusting the battery’s charging characteristics accordingly.
  • Extensive electronic protections are available on Heliac PCU. There are a number of protections that the Home PCU ensures. It stops reverse current flow from battery to solar array, it provides load short circuit protection, and it provides battery / solar panel reverse protection through DC fuse and Overload protection also.
  • It is very compatible with IT load. IT loads which provide protections to IT instruments like computers, printers etc
  • The frequency of DG output is a very vital parameter that always varies. And if the system is in DG enable mode then the system will be compatible to take any of the frequency as the input source frequency.
  • Operating Mode Selection:
    • PCU Mode Priority – Solar Energy → Battery → Grid
    • Smart Mode Priority – Solar Energy → Grid → Battery
    • Hybrid Mode – Priority for load → Grid → Solar Energy → Battery
    • Priority for battery charging – Solar → Grid
