The Low Strings page shows losses at the DC combiner, recombiners or DC feeder input when data from current measurements at those points in the plant is available. An underperforming string is one that is performing worse than its neighbours near the plant.
The typical remedy for underperforming strings is to check module health, DC connections, and fuses, and the specific strings, inverters, and combiners suffering from low DC performance are automatically highlighted in the corrective action recommendations.
DC Health - Underperforming String - Summary
The summary KPIs give a quick overview of the actual, revenue and recoverable losses due to underperforming strings. In addition, the total number of underperforming DC inputs is displayed.
Underperforming String Losses per Inverter
The Underperforming Strings Loss by Inverter bar graph shows the losses for each string over the selected time frame, sorted by loss.
Plant-Level Losses due to Underperforming DC inputs
The Plant-level Losses due to Underperforming Strings graph shows the total loss due to underperforming strings at the plant level over the selected time frame.
