Use this Assistant in systems with a grid-tie PV inverter connected to the AC out of a Multi or Quattro, where ESS is not applicable. Off-grid systems, and in certain cases also backup systems.

When the system is in inverter mode, this Assistant controls the output power of the grid-tie inverter by changing the AC output frequency of the system. A mechanism commonly refered to as Frequency Shifting. It does so to regulate the charge process: limiting the output power of the Grid-tie inverter to proper manage the charge and also prevent overcharge of the batteries.

This Assistant will be idle when the Multi or Quattro is connected to mains.

Take note of the factor 1.0 rule.
