Defaults
The web portal comes with preconfigured alarms. Our experience shows that over-sensitive alarms can lead to users ignoring them, undermining their value. Therefore, our default settings prioritize generating alarms late rather than too early.
You are encouraged to adjust these settings based on your knowledge of specific installations to create stricter and more timely rules where appropriate.
This page gives an overview of the alarms which are configured by default.

| Low uptime | Low uptime | N/A | • Installation • Smart grid controller site • Inverter • Hybrid inverter • String | • All: lookback period from 3 days ago to 1 days ago, threshold of 80%** |
It is not uncommon for an EV charger to remain unused for several days. Consequently, the default lookback period for the "Charger energy is zero" alarm is set to 7 days to avoid frequent nuisance alarms.
- Meteo Data Dependency: Both Performance Ratio (PR) and Uptime calculations require meteorological data (like irradiation). Depending on the data source and location, this data might have a delay of up to a day.
- Fluctuations: PR values can fluctuate based on the accuracy of meteo data and specific daily weather conditions (e.g., rapidly changing cloud cover).
The default lookback period (3 days ago to 1 day ago) and thresholds (50% for PR, 80% for Uptime) to account for these potential delays and fluctuations.
