Name of Derating and Cause
Solution
- LIMxxx% CODE:05
Power limitation due to excess temperature:
The message indicates that a power limitation is active since
an excess temperature condition has been recorded inside the
inverter (This parameter depends also on the power which the
inverter must provide since the measurement of temperatures is
taken internally and is influenced by the heat dissipated by the
components of the inverter itself).
LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power
• Check that the inverter is not exposed to direct
sunlight. Wait for the temperatures to which the
inverter is exposed to return to the operating range
and for the inverter to cool down.
- If the problem (once the ambient temperature
has returned within the range) persists, contact
customer assistance.
- LIMxxx% CODE:06
Power limitation for input over-voltage:
The message indicates that a power limitation is active since an
input overvoltage (AC) has been recorded.
LIM xxx% = Power reduction percentage
Examples:
LIM 100% = no power limitation
LIM 50% = limitation to 50% of the output nominal power
• It is necessary to measure the input voltage inside
the inverter with a voltmeter.
- If it is higher than the maximum voltage of the
operating range, the alarm is genuine and it is
necessary to check the configuration of the PV
generator. If the voltage has also exceeded the
maximum input threshold the inverter could be
damaged.
- If it is lower than the maximum voltage of the
operating range, the alarm is caused by an internal
malfunction and it is necessary to contact customer
assistance.
