Basic information on the grid injection inverter, zero discharge. 15000w 380v Three-phase

The GridFree Inverter with Limiter with an output of 15000W works with the input voltage range of 200-800Vdc. The limiter can reduce the output power according to the actual consumption of the house. MPPT function provides maximum efficiency of solar panels .

The GridFree inverter with limiter is a revolutionary solution for domestic solar installations that works in a similar way to other GridFree microinverters, but is capable of reducing its own production according to the current consumption of the house and thus completely avoiding overflows to the public grid .

These inverters are designed for internal use and you can monitor the current values on the color screen where the following values are displayed:

  • The current output power of solar panels
  • The energy supplied from the public grid
  • Voltage at DC input
  • Temperature
  • Network voltage
  • Date and Time
  • Daily production graph
  • Inverter setting


The Grid Connection Inverter is an inverter that allows us to interconnect with the electricity grid without the need for batteries , which is why this type of installation is economical and very profitable in the long term, given its low cost from a simple installation and with few electronic devices that make the system more expensive.
For a grid connection installation to function correctly, we will need a group of solar panels, previously calculated to suit the needs of each case, and a grid connection inverter, which will allow us to transform energy from the solar panels in order to make use of it
The inverters have a zero grid injection system, this means that in the event that the solar installation is producing more energy than the house or industrial building is consuming, the zero injection system will allow us to reduce the inverter power only if there is an energy surplus.
In summary, the functionality of zero injection systems is to lower the power of the inverter when the energy produced is higher than the energy consumed, thus preventing it from being poured into the general electrical grid.

    Operation of a solar self-consumption kit:

    With this kit you can save electricity on the electricity bill of your home, during the sun hours everything that the solar panels produce will be injected into your home and power the electrical appliances for free.

    This kit does not need permits from any power company to be installed, since its "zero discharge" system to the power grid does not allow you to dump anything, and in this way we save any legal paperwork.
