“Incorrect, try again,” press the “Back” key and enter the password again. When the password has been
entered correctly, you can enter the menu. Now you can use the “Up” and “Down” keys to select the
“1.Enable” or “2.Disable” option and select it with the “OK” key. If the “1.Enable” option is selected, you can
use the “Up” and “Down” keys to select the options “Under-excited”, “Grid Manager”, and “Over-excited”, and
you can indicate the value of the reactive power produced for each of them. If the setting is successful, “OK”
will be displayed; otherwise, “Error” will be displayed.
Power derating
Select 17 “Derating P(W)” and press “OK” to enter the relative menu, from which you can enable the
“Derating” function, i.e. the possibility to set the power produced by the inverter. The display will show
“Enter PWD!”, press “OK” to enter the password. Enter the password “0001” using the “Up” and “Down” keys
to select the digit and “OK” to move to the next one, and confirm. If the display shows “Incorrect, try again,”
press the “Back” key and enter the password again. When the password entered is correct, you can enter the
menu. With the “Up” and “Down” keys you can set the “1. Enable” and “2. Disable” option, and select it with
the “OK” key. If the “1.Enable” option is selected, use the “Up”, “Down” and “OK” keys to select the percentage
value (between 0 and 100) of the maximum power that the inverter will produce; if the solar radiation
allows a greater amount of energy to be produced, the inverter will carry out the necessary operations to
limit the output power to the set value. If the setting is successful, “OK” will be displayed; otherwise, “Error”
will be displayed.
P(GRID) CHECK
Select “18. P(grid) Check” and press “OK” to enter the relative menu, from which you can enable the “Reflux
Power” function, i.e. the possibility to set the maximum power fed into the grid. The display will show “Enter
PWD!”, press “OK” to enter the password. Enter the password “0001” using the “Up” and “Down” keys to
select the number and “OK” to move to the next one, and confirm. If the display shows “Incorrect, try again,”
press the “Back” key and enter the password again. When the password has been entered correctly, you can
enter the menu. With the “Up” and “Down” keys you can set the “1. Enable” and “2. Disable” option, and
select it with the “OK” key. If the “1.Enable” option is selected, you can use the “Up”, “Down” and “OK” keys to
select the value (expressed in kW, up to two decimal places) of the maximum power that the inverter will
feed into the grid. In this way the inverter can feed a maximum power of between 0 kW and the rated power
of the inverter into the national grid, based on the solar radiation available and the domestic consumption. If
the setting is successful, “OK” will be displayed; otherwise, “Error” will be displayed.
Note:
To activate the Reflux Power mode in single-phase inverters, it is necessary to install a CT current
sensor, as described in the appropriate procedure.
