The nameplate on a Yonkers inverter is a short string of characters. It is either the string on the Con Edison application or it is a different project. Yonkers solar as-built drawings exist to record what is actually on the building. On October 14, 2026 the usual break is an equipment swap the field made and the paperwork did not. An as-built that only satisfies Yonkers still fails if the inverter on the wall is not the inverter on the SIR application.
The city package and the utility package
Yonkers closeout and Con Edison permission to operate are different packages for different reviewers. The city package answers the building department: what was built, where it sits, and how the installed work compares with the permit the city issued. The utility package answers Con Edison: what will operate in parallel, at what AC output, through which inverter model, at the point the application described.
What Yonkers is checking
The building department is closing a construction permit. It wants the as-built to agree with the work it can see. A closeout acceptance ends that review. It does not operate the system on Con Edison's network. Do not invent a Yonkers fee or a local form number. If the permit office wants a city-specific transmittal, ask for the current list. A form code from another town will be wrong.
What Con Edison is checking
The utility file is the permission-to-operate package. It has to describe the inverter that is installed. Con Edison's revised Standardized Interconnection Requirements tariff took effect October 1, 2026. That tariff did not create a Yonkers form, and it did not revise your equipment list. Permission to operate still requires the utility file to match the wall.
Sending one PDF to both reviewers, with a cover note that says "as-built," is how an inverter mismatch survives until somebody reads the model number. Keep two transmittals. They can share sheets. They should not share a single cover that pretends the reviews are the same.
When the wall and the SIR application disagree
Installers change inverter models for ordinary field reasons. A model is back-ordered. The stringing count forces a different unit. A distributor substitutes a successor with a new suffix. The crew notes it on a punch list. The SIR application still shows the model that was submitted.
If the installed model is not the applied model, the permission-to-operate file is wrong even after a Yonkers inspector has walked the site. AC kW and export can change with the new unit. Any study that was required studied the original equipment. Changing only the city set does not repair the utility file.
The practical test is a character match. Manufacturer, model, and quantity on the wall, on the as-built, and in the utility file should be the same string. If the suffix changed, the model changed. Mark the old string as removed so two models are not both labeled current.
If AC kW or export changed with the inverter, those values move with the model. A permission-to-operate request that still cites the original output is a request to operate a project you did not build. Update the utility file to the installed ratings. The October 1 tariff revision did not perform that update. Tariff text is not a revised equipment list.
Yonkers solar as-built drawings that have to move together
Four parts of the set move when the inverter changes. Leaving one of them on the old model is enough to fail a comparison. Other sheets stay put unless the swap forced them to change. A module layout that did not change does not need a decorative revision. Revising every sheet hides the four that matter.
The one-line shows manufacturer, model, quantity, AC rating, and the point where the system ties to Con Edison. Those entries match the nameplate. If the inverter count changed, the one-line changes with it. Do not leave the old symbol looking connected.
The equipment schedule carries the same model string as the one-line. Remove the superseded model or label it not installed. Quantity, AC output, and any export limit stay on that same row.
The placard changes if the model changed. The detail has to name the installed model and the ratings a person will read at the equipment. A detail copied from the permit set will keep advertising the inverter you did not hang. This is record drawing work, not a new study.
The site photo index numbers the photos and says which sheet each one supports. Include a frame where the inverter nameplate can be read, plus the placard and a shot that locates that inverter. A wide wall photo is not a nameplate. If the index still captions the old model, the photos and the schedule disagree.
Cloud those four items and put a revision note that says the inverter model was updated to the installed unit. If AC kW or export also changed, say that in the same note, with the old value and the installed value, so the utility reviewer does not have to guess which number is current.
What the Con Edison file still needs after October 1
The revised SIR tariff has been in effect since October 1, 2026. For this as-built, that fact has a narrow meaning. The utility reads the closeout against the current SIR. It does not mean the original application quietly updated itself when the tariff changed. Someone has to submit the record that matches the wall.
Pack the utility file as its own set: revised one-line, revised equipment schedule, placard if the model changed, and the photo index. In a short cover note, state the model on the application, the model on the wall, and whether AC kW or export changed. Do not invent a portal field name. If Con Edison's current instructions route those sheets through its portal, follow the live instructions.
The city file can use the same revised sheets. It still needs whatever Yonkers currently asks for to close a permit, confirmed with the building department rather than copied from another municipality. Keep the transmittals separate so a city stamp is not the only mark on the utility set.
Who draws the record, and who hung the inverter
Athol prepares the as-built drawings. The crew on site mounted the inverter. The drawings record what the installer reports and what the photos show, and they are revised until the model string matches in every place a reviewer looks. If the revised interconnection set needs a New York PE stamp, that stamp belongs on the revised set, not on a permit drawing that still shows the old inverter.
As-built drawings are the service for this revision. The Con Edison side of the file is discussed in Con Edison solar interconnection, and the record-drawing habit is laid out in solar as-built documentation. The original application package sits under interconnection drawings, and the statewide SIR context is on New York SIR interconnection.
Match the wall, the one-line, the schedule, the placard, and the photo index. Then send the city and the utility their own packages. One of those packages being finished does not finish the other.
