Modules QHP Alterna

The revolution of the photovoltaic module

Invent QHP Alterna is the first alternating current photovoltaic module.

With the module Invent QHP Alterna,  is no longer necessary to prepare complicated technical spaces to set up the photovoltaic system. In addition to the module no other equipment is needed since the functions normally carried out, up to now, by the inverter outside, now are carried out by the module itself.

The modules QHP Alterna are supplied with only positive tolerance (0 / + 6%).

  • Compact technology

    In the module Invent QHP Alterna all the technology is compacted into a single plank fixed in the back of the panel.

    The control system is placed in the instrument panel and the management of the module with the alternating current output.

  • Independent modules

    Unlike standard systems, in a system with Invent QHP Alterna each module is independent of all the others: so if one were to have a problem even temporary (shadow, dirt, or failure), this will not involve the production of energy of the ‘whole system, but will limit its effect to only the affected module.


  • Increased performance

    In a photovoltaic system, the use of the modules Invent QHP Alterna allows:

    To increase the efficiency of the system up to 25%;

    To Optimize the system performance even with modules tilted and positioned differently;

    System efficiency even with failed modules;

    Reduction of installation spaces

  • Quick Connect plug & play

    The modules Invent QHP Alterna have special connections quick plug & play.
    The electrical connection of the modules has never been so easy and affordable for everyone.

  • NanoClean treatment

    The Invent modules are treated with a special nanotechnological process for maintaining the cleanliness of the panel in time.

    The treatment gives the surfaces the permanent property of “thicken” the dirt or limestone favoring periodic cleaning.

    In the pictures you can see the difference in behavior of water and limestone on the surface treated with nanotechnology.
