The DC Health page shows information about the operational status of the DC strings in the photovoltaic array. It distinguishes between strings that are down (not operational) and strings that are still operating but producing less energy than would be expected relative to neighbouring strings.
The DC Health page is divided into three sections: summary, down strings, and low strings.
The DC Health summary offers a holistic overview of the current and past history of DC string health and enables a user to identify promising actions to improve plant performance quickly.
DC Health - Summary
DC Health Summary section offers an overview of down and low strings/DC input, and the losses due to down and low strings/DC input in the system.
DC Health View and DC underperformance Loss View
DC Health View is a chart of DC health losses by inverter. It shows both recoverable and unrecoverable energy losses due to DC health problems for each inverter. Both down and low strings are shown, distinguished by colour.
DC Underperformance Loss View shows a heat map across all inverters and time, showing the losses of DC health issues across the time period. The color scale is used to indicate the relative health. The higher the DC health losses, the color gets more towards red.
Low and Down String Count
Low and Down Strings Count chart shows the count of low and down strings/DC inputs on each day over the selected time period.
