Unbalanced Phases is an application that allows the three phase IMEON 9.12 to adjust the injection of solar energy separately per phase, depending on the load on each phase.

A standard three phase solar inverter injects one third of the total generated solar production on each phase symmetrically without taking into account the consumption per phase.

In practical example if a site consumes:

  • 2kW on phase 1,
  • 3kW on phase 2, and
  • 1kW on phase 3,

a total of 6kW, a standard solar inverter would inject 2kW to each phase. As a result:

  • consumption of phase 1 would be compensated, while
  • consumption of phase 2 would require a complementary 1kW of power to be drawn from the grid, while
  • consumption on phase 3 would be compensated, with 1kW of power exported to the grid.

This is not always the best solution, especially for networks which employ per-phase metering and which prohibit export of energy to grid.

When the Unbalanced Phases application is active, the IMEON will inject the amount of energy needed to supply the load on each phase, within the constraints of its power rating.  In the above example IMEON will adjust the quantity of electricity injected per each phase to lock onto the exact consumption values.
