CHOOSE THE FRONIUS SOLUTION FOR
LIMITED OR ZERO FEED-IN SITUATIONS
/ The Fronius Feed-in Limitation system is a simple and economical solution using the Fronius Smart Meter and Fronius
Datamanager 2.0 and fully complies with the current UK DNO requirements.
/ 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 Webinterface and is set in whole percentages from 0 - 100% or as a value in Watts.

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 webinterface of the inverter or Fronius Datamanager.

a whole percentage from 0 - 100%, or as a value in
Watts, for maximum grid feed-in power
/ 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, only one
Datamanager is required for up to 100 inverters*.
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.

/ What are the DNO requirements?
The requirements, which are all met by the Fronius solution are as follows:
/ The system must be fail-safe
/ The system must not rely on wireless communication between the various components of the export limiter system
/ The system and the whole installation must meet all relevant power quality requirements
/ The system must react within one second
/ The system must reduce output within 5 seconds
