Output power derating solar inverter
This power reduction process is called “derating”. Derating protects sensitive components within the unit and prolongs its lifetime. When the ambient temperature falls below the specified maximum, normal power output resumes.

6 FAQs about [Output power derating solar inverter]
What is derating a solar inverter?
Derating is the controlled reduction of the inverter power. In normal operation, inverters operate at their maximum power point. At this operating point, the ratio between PV voltage and PV current results in the maximum power. The maximum power point changes constantly depending on solar irradiation levels and PV module temperature.
Does temperature derating affect a PV inverter?
In this case, the maximum DC voltage of the inverter acts more as a technical boundary than a normal operating curve. There is no PV array operating point that requires the inverter to feed in at full power at temperatures above 31°C (at 800 V). On principle, temperature derating has no negative effects on the inverter.
Why does the inverter switch to the electric current derating operating state?
The inverter switches to the electric current derating operating state to protect itself from an overload. If this display appears regularly, the system design and module circuitry should be checked by an installer. Further Information is available in the technical information on derating (Sunny Boy and Sunny Tripower).
What is a temperature derating inverter?
Temperature derating prevents the sensitive semiconductors in the inverter from overheating. Once the permissible temperature on the monitored components is reached, the inverter shifts its operating point to a reduced power level. The power is reduced in steps. In extreme cases, the inverter will shut down completely.
Why does my inverter keep displaying a 'derating' warning?
If the inverter remains in this state for more than a few minutes, it issues a “Derating” warning. The inverter continues to display this warning until it shuts down at sunset. Temperature derating can occur for many reasons, e.g. if the inverter cannot dissipate heat due to unfavorable installation conditions.
How to avoid derating at peak PV array outputs?
In order to avoid derating at peak PV array outputs, an inverter with a nominal power of more than 100% of the PV array power could be selected. However, this would shift a larger proportion of partial load yields to a range within which the inverter is relatively inefficient.
