Export Limitation


The Fronius feed-in limitation system is a simple and economical solution using the Fronius Smart Meter and Fronius Datamanager 2.0.

The limitation is based on the inverter shifting its optimum operating point to adapt the output power to not exceed a predefined export value to the grid. This predefined value is set within a password protected area of the Fronius Datamanager web interface and is set in whole percentages from -10% - 100% or as a value in Watts.
/ Dynamic Feed-in Control
If there are feed-in limits (i.e. max. 70% of the kWp or max. 50 kW) self-consumption should first be considered, before the inverters power is reduced. With the Fronius dynamic feed-in control it is possible to set an individual power limit and to connect the Fronius Smart Meter directly to the inverter. The setting can easily be done on the web interface of the inverter or Fronius Datamanager.
/ What equipment do I need?
All you need is a Fronius Smart Meter and a Fronius Snapinverter (Fronius Symo, Fronius Primo, Fronius Galvo, Fronius Eco) with built in Datamanager 2.0 or external Datamanager 2.0 Box which must have the latest software version installed (for zero export requirements contact us directly). For large installations of up to 100 inverters* only one Datamanager is required.

The Fronius Smart Meter is a bidirectional meter which optimises self-consumption and records the building’s load curve. Thanks to highly accurate measurements and rapid communication via the Modbus RTU interface, dynamic feed-in control when feed-in limits are imposed is fast and accurate. Together with Fronius Datamanager 2.0, Feed-in limitation set-up is made easy.
*Installation/inverter location/cable type/cable run length dependent.

Fronius inverters can also be controlled via Modbus RTU or TCP/IP or via configurable I/O ports from third party devices in order to achieve export limitations. For more information, please email pv-sales-australia@fronius.com or contact one of our sales partners.
