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 limita-
tion
Energy companies or grid operators may stipulate feed-in limitations for an in-
verter (e.g. max. 70% of kWp or max. 5 kW).
The feed-in limitation takes account of self-consumption by the household be-
fore the power of an inverter is reduced:
-
A custom limit can be set.
-
A Fronius Smart Meter can be connected to the Modbus push-in terminal of
the data communication area at the M0/M1- / M0/M1+ connections for Mod-
bus data.
With the inverter, any PV power that is not allowed to be fed into the public grid
is used to charge the battery instead and/or used by the Fronius Ohmpilot so
that it does not go to waste. The feed-in limitation is only active if the power fed
in is higher than the set power reduction.
"Power limitation” deactivated
The inverter converts the entire available PV power and feeds it into the public
grid.
"Power limitation” activated
The entire PV system is restricted to a set power limit. The value of the total per-
missible feed-in power must be set.
"Total DC system power"
Input field for the total DC system power in Wp.
This value is used if the "Maximum permitted feed-in power of the entire sys-
tem" is specified in %.
"Soft Limit"
If this value is exceeded, the inverter will regulate down to the set value within
the time required by national standards and regulations.
"Hard Limit"
If this value is exceeded, the inverter switches off within max. five seconds. This
value must be higher than the value set for "Soft Limit".
"Maximum permitted feed-in power of the entire system"
Input field for the "Maximum permitted feed-in power of the entire system" in W
or % (setting range: -10 to 100 %).
