Production-Based Availability (Inverter Normalized)

This signal is the final stage of the Inverter-normalized Production-based Availability KPI. It gives the production-based availability of a solar inverter.

or in simpler terms:

Production-Based_Availability__Inverter_Normalized__-_Description_2.png
Technology

Solar

Remarks

Note that this signal is based on the energy produced at the Primary meter of this inverter, which can also be expressed as the sum of the Effective Power for all inverters mapped to the same primary meter.

This signal should not be confused with Production-based System Availability (Inverter).

Equation

Where:

AP,normalized

is the Production-based availability (inverter normalized)

Eeffective

is effective energy

ELPtot,normalized

is the Total Lost Production (Inverter Normalized)

Peffective

is Effective Power

T

is the device resolution in hours

Usage Example

The easiest way to view Production-Based Availability (Inverter Normalized) is through a Signal Bar Table. Here, we can see that this inverter is performing at 95.58% of its potential, according to the Production-Based Availability (Inverter Normalized) KPI:

To drill down into the detail of when the inverter was over- and under-performing, we can plot a bar chart:

or a line graph:

Another way to visualize Production-Based Availability (Inverter Normalized) is to plot the Lost Productions against Energy, to give perspective on how great the losses were. Note that, the Energy signal is not Effective Energy, that is, cable losses are not taken into consideration:

It is also possible to plot two inverters side by side, so you can compare their performance:
