The power factor curve can only be disabled when the voltage goes back to
a value below the shutdown voltage level, adjustable value between 90 %
and 100 % of nominal voltage level, with default voltage level at 100 %
adjusted at factory.
2.4.3 Regular Operational Voltage Range
For Country Brazil (Code “BRA”)
The inverters can operate within the voltage limits defined in the following table.
Tab. 2-3 Disconnection related to Voltage
When the voltage level is out of the operational levels shown in the table, the
inverter will disconnect from the grid.
If a disturbance lasts less than the required disconnection time, the inverter can
reconnect to the grid if the voltage level goes back to normal levels after the
disturbance.
Remarks:
(1) The maximum time to disconnect refers to the interval between the
abnormal voltage level and the action of inverter (disconnect from the grid).
(2) When the grid voltage is higher than (110 % V
nominal
- 5) V, the inverter will
reduce the active power export to grid according to the following equation:
△
P
= P
nominal
x R
Where:
−
△
P is the variation of active power export to grid (in %) related to the nominal
power.
− P
nominal
is the nominal grid power.
− R is the desired reduction in active export power (expressed in % of Volt),
adjusted in -20 % per Volt.
For Country Mexico (Code “MX”)
The inverters can operate within the voltage limits defined in the following table.
