Lost Production to Downtime (inverter normalized)

Lost Production to Downtime (inverter normalized) is used as part of the Production-based Availability (inverter normalized) calculation method. This method dictates that lost production only be allocated to downtime if the entire solar site is offline, as indicated by the grid meter based availability.

Note

This signal is the same as Energy Theoretical (Inverter) for the period where all grid meters are unavailable, as the produced power then is 0.

Negative values are not allowed.

Usage example

Here is the Lost Production to Downtime (inverter normalized), which shows how the signal is 0 when the grid meters are available.
