CAUTION!
Risk due to unauthorised access.
Incorrectly set parameters can negatively influence the public grid and/or the in-
verter feeding energy into the grid, and lead to a loss of conformity with the
standard.
▶
The parameters may only be adjusted by installers/service technicians from
authorised specialist companies.
▶
Do not give the access code to third parties and/or unauthorised persons.
Feed-in limit Energy companies or grid operators can prescribe feed-in limits for an inverter
(e.g., max. 70% of the kWp or max. 5 kW).
The feed-in limit takes account of self-consumption in the household before the
power of an inverter is reduced:
-
An individual limit can be set.
-
A Fronius Smart Meter can be connected to the Modbus push-in terminal of
the data communication area, at the terminals M0/M1- / M0/M1+ for Mod-
bus data.
The feed-in limit only becomes active if the power of feeding in is higher than the
set power reduction.
"Off"
The inverter converts all available PV energy and feeds it into the public grid.
"Limit for the entire system"
The entire PV system is limited to a fixed power limit. A value must be set for the
permissible total power of feeding in.
"Total DC power of the system"
Input field for the total DC power of the system in Wp.
This value is used if the "Maximum permitted power of feeding in of the entire
system" is specified in %.
"Hard limit"
If this value is exceeded, the inverter switches off within max. 5 seconds. This
value must be higher than the value set for "Soft limit".
"Soft limit"
If this value is exceeded, the inverter readjusts down to the set value within the
time required by the national standards and regulations.
"Maximum permitted power of feeding in of the entire system"
Input field for the "Maximum permitted power of feeding in of the entire system"
in W or % (setting range: -10 to 100%).
If there is no meter in the system or if a meter has failed, the inverter limits the
power of feeding in to the set value.
