For Country “IT”
The inverter can be connected to grid and start to generate electrical power
when the grid frequency is between 49.90 Hz and 50.10 Hz.

For a normal operational start-up, the observation time is 30 s and the
gradient is 20% Pn/min.

For an automatic reconnection after tripping of the interface protection, the
observation time is 300 s and the gradient is 20% Pn/min.
For Italy, the over- / under- frequency protection value and time can be
controlled by the SPI function, through LCD setting or remote command via
RS485 communication. Please refer to “2.3.6 SPI and Auto Test (Italy only)”
for details.
2.3.4 Active Power Regulation
Over-voltage Response
When the grid voltage is higher than (110 % V
max
- 5) V, the inverter will reduce
the active power export to grid according to the following equation:
△ P = P
nom
x R
Where:
− △ P is the variation of active power export to grid (in %) related to the
nominal power.
− P
nom
is the nominal grid power.
− R is the desired reduction in active export power (expressed in % of Volt),
