Basic info

Description

The chart displays the results of all performance ratio (PR) calculations configured for your system over the chosen period (month/year/total).

Prerequisites

KPI editor
You have added multiple PRs. See KPI editor for PR and system availability.

Further details

PR chart thresholds

The KPI Editor also allows you to define the thresholds for different performance levels. See KPI editor for PR and system availability.

Caution

If your site has multiple power plant controllers (blue’Log XC data loggers or third-party PPCs) and you want to monitor each individually, each controller should be configured as a separate system, not as a subsystem. Otherwise, the performance ratio will not be calculated.

Example: A site has PV production across three rooftops, each with its own PPC. In this case, configure each rooftop in VCOM as a separate system.

To view the overall PR for the entire site, you can combine these individual systems into a virtual system in VCOM.
