Understand the two equipment ratings
The combined panel rating and inverter output rating can differ. Reaching the inverter’s limit during strong production conditions does not automatically mean it is broken or needs to be enlarged.
Review the original design and inverter specification together. Ask how the expected annual energy production accounts for the selected equipment.
Record the shape and timing
Save several complete daily graphs with the vertical-axis units visible. Note the ceiling value, how long it lasts, and whether the same shape appeared when the system was first installed.
A new, lower ceiling deserves a different review from a long-standing pattern. Include the date of any inverter replacement, configuration change, battery addition, or service visit.
Do not confuse a plateau with an outage
Tell the professional whether the chart levels off above zero, falls to zero, or contains missing data. Include the app timestamp and exact warnings. Use the separate inverter-error guide if an alert accompanies the change.
Do not change export limits, grid settings, or protection settings to try to remove a plateau. Those settings need review against the equipment, design, and applicable connection requirements.
Ask the right upgrade question
Before paying for a larger inverter or more panels, ask what problem the proposed change solves and what evidence supports it. A different peak number does not on its own establish the value of an upgrade.
For a DFW assessment, send the system and inverter ratings if known, sample graphs, and your concern. We can review the requested service scope without assuming a replacement is needed.
