Path-Q Solar

What should I do if production data is missing only during the brightest part of the day?

Answer

First determine whether generation stopped or only the monitoring data stopped. A gap limited to peak daylight can result from inverter shutdown, communications or data-logger failure, or a time-series display issue; check the inverter's local status and event history before assuming lost production.

Key points

  • Compare the monitoring portal's interval data with inverter production totals and any separate production-meter data.
  • A utility net meter usually shows net power exchanged with the grid, not solar generation by itself, so it may not directly confirm production.
  • Check whether the inverter was online, producing, or reporting errors during the gap.
  • Look for repeated gaps at the same time, network interruptions, clock errors, and firmware or portal changes.
  • Do not open energized equipment or reset devices unless the manufacturer and qualified provider authorize it.

What it depends on

  • Monitoring architecture and data sources
  • Inverter status and event logs
  • Communications, networking, and time settings
  • Availability of inverter totals or separate production-meter data

Risks and trade-offs

  • A portal gap may hide normal generation, while an inverter shutdown represents actual lost production.
  • Repeated peak-hour shutdowns can indicate thermal, grid, or equipment problems.
  • Uncoordinated resets may erase diagnostic information or create safety risks.

Information you may need

  • Portal interval data and inverter totals
  • Inverter display, event logs, and status history
  • Network and communications records
  • Separate production-meter data if available and provider support records

Your next step

What to do next

Compare portal data with inverter totals and any separate production data for the same period, document recurring timestamps and error codes, and open a provider service case if generation or reporting is confirmed to stop.
