P ower limitation messages
The equipment can signal possible output power limitations which may
occur on the basis of:
- settings made by the user
- settings required by the grid standard of the country of installation
- protective devices inside the inverter

The following table gives the complete list of power limitation messages relating to string
inverters.
Some messages may not be used depending on the inverter model installed.
- Web server message
- Warning
Name of Derating and Cause Solution
- LIMxxx% CODE:00
Power limitation:
The message indicates that the user has set an output power
limitation for the inverter.
LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power

- LIMxxx% CODE:01
Power limitation due to over-frequency:
The message indicates that the user has set a power limitation
due to over frequency in order to reduce the maximum output
power of the inverter when the grid frequency exceeds certain
limits.
LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power

- LIMxxx% CODE:02
Power limitation due to over-voltage:
The message indicates that the user has set a power limitation
due to overvoltage (parameter U >(10 min)) in order to reduce the
maximum output power of the inverter when the reading of the
average grid voltage exceeds certain limits.
The sampling of readings is done every 10 minutes (U>(10min)).
LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power

Anti-islanding power limitation:
The message indicates that a power limitation is active because
a situation of "islanding" has been recorded.
LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power

- LIMxxx% CODE:04
Power limitation due to low grid voltage:
The message indicates that an output power limitation may occur
since a low grid voltage (AC) condition has been recorded.
LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power
