Safety and grid requirements
Country setup The "Country setup" menu area is intended exclusively for installers/service technicians
from authorised specialist companies. The access code must be requested from the na-
tional/international Fronius point of contact using an application form.
The selected country setup for the respective country contains preset parameters ac-
cording to the nationally applicable standards and requirements. Depending on local grid
conditions and the specifications of the energy provider, adjustments to the selected
country setup may be necessary.
CAUTION!
Risk due to unauthorised access.
Incorrectly set parameters can negatively influence the public grid and/or the feed-in of
power into mains by the inverter, and lead to a loss of conformity with the standard.
▶
The parameters may only be adjusted by installers/service technicians from author-
ised specialist companies.
▶
Do not give the access code to third parties and/or unauthorised persons.
CAUTION!
Risk due to incorrectly set parameters.
Incorrectly set parameters can negatively influence the public grid and/or cause faults
and failures on the inverter, and lead to the loss of standard conformity.
▶
The parameters may only be adjusted by installers/service technicians from author-
ised specialist companies.
▶
The parameters may only be adjusted if the energy provider permits or requires this.
▶
Only adjust the parameters taking into account the nationally applicable standards
and/or directives and the specifications of the energy provider.
Feed-in limitation DNO or grid operators may stipulate feed-in limitations for an inverter (e.g. max. 70% of
kWp or max. 5 kW).
The feed-in limitation takes account of self-consumption by the household before 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 connections M0/M1- / M0/M1+ for Modbus data.
With the inverter, any PV power that is not allowed to be fed into the 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. The battery is charged first or the energy is consumed on the Fronius Ohmpi-
lot.
" Limit for entire system "
The entire PV system is limited in accordance with a set power limit. If this setting is dis-
abled, the entire available PV
‑
power is converted and fed into the grid.
"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 system" is spe-
cified in %.
