To set a percentage based on total installed PV power:
1.
2.
3.
4.
3
The inverter output power will now be limited to a percentage value of the total installed PV
power.
For example: When the installed power is 18 kWp, and the output power of the inverter is limi-
ted to 70%, then output power = 18x0.7 = 12.6 kW.
To set a percentage based on nominal AC output power:
1.
2.
3.
4.
The inverter output power will now be limited to a percentage of the nominal AC output power.
For example:
For a 12.5 kW inverter when the output power is limited to 70%, then output power = 12.5x0.7
= 8.75 kW.
3.3.4. Configuration via Web Server or Service Interface (Inverter
Level)
There are four methods to limit the output power of the inverter:
1.
2.
3.
4.
To set an absolute value:
1.
2.
3.
4.
The inverter output power will now be limited to an absolute value. For example: 7 kW.
To set a percentage based on total installed PV power:

In the inverter display, go to [Setup → Grid management → Output power → Lim type].
Choose "Pct based on PV" .
Choose "Output power limit" and enter the applicable output limit of the inverter (for
example 70%).
Click "Save".
In the inverter display, go to [Setup → Grid management → Output power → Lim type].
Choose "Pct based on ACP" in the Lim. Type menu.
Choose "Output power limit" and enter the applicable output limit of the inverter (for
example 70%).
Click "Save".
Limit output power by external input (default setting).
Absolute value [W].
Percentage based on total installed PV power (peak PV power connected to the inver-
ter).
Percentage based on nominal AC output power (kW – nominal AC output power of the
inverter).
Go to [Inverter → Setup → Grid management → Output power].
Click on "Absolute value".
Type the applicable output limit of the inverter (for example 7000 W).
Click "Save".
Go to [Inverter → Setup → Grid management → Output power].
Click on "Percentage based on total installed PV power".
