Trust the LCD for the hour you can see
An app yield that looks fake needs a clock and a definition of what the number is. Import, export, PV, and load are four different flows, and an app tile often adds them up with a label a house owner cannot see. A dongle that was offline will draw a flat line and then a catch-up that is not physics. A current sensor on the wrong conductor can show export the bill does not. The long guide stays canonical. This stop-page tells you to stand at the inverter at noon, photograph PV watts, and only then open the app for that same hour. If the LCD is healthy and the app is flat, fix the stick. If both are low, look at shade, soiling, or the string. We do not promise a units number from the app, and this page does not publish a Modbus map.
Do not correct the yield by editing a register. The plates did not break physics because a tile said they made more than the roof can, and they did not fail because a tile said they made nothing on a sunny hour when the LCD showed watts. A scaling error in the app is common. The photograph of that hour on the glass is the record you can defend. The meter and the bill are the other record. This desk will not certify units for a dispute from an app screenshot. New Pakistani files after 9 February 2026 are net-billing under SRO 251(I)/2026, so the bill's export line is a filing fact, not a cloud fact. The carton and the DISCO bill beat the website, and they beat the app.
Four flows, one sunny hour
Before you accuse anyone, name the flow. PV is what the roof made. Load is what the house used. Export is what left toward the street. Import is what the street sold you. A single hero number that mixes those four will look wrong even on a perfect day. Photograph the LCD tile that says PV, and write the app tile's exact label, not the word you think it should mean. If the app has no label, say that. Take the pair at noon, not at midnight, because a night screenshot cannot see the roof. One honest hour is enough to decide whether you are in a stick fault or a roof fault. A month of flat history is not required for that decision, and a month of flat history is what a dead stick manufactures.
If both screens are low, do not start with a register. Look outside. Shade, soil, and a mixed or idle tracker are the roof reasons, and they already have pages. Soiling is the dirt account. MPPT is the idle-tracker account. The dongle page is where you go when the LCD was healthy and the app was not. Keep those doors separate in the note so the next person does not wash the roof to cure a dead stick, or replace a stick to cure a tank shadow. Photograph the glass if it is brown with dust, and say the month. September production is not judged against an STC brochure. The Multan heat page sets that expectation. A low but real noon on the LCD can be an honest hot month.
A flat day and a sudden catch-up are the stick, not the plates
When the app draws zero through the afternoon and then a vertical jump after the router returns, the plates did not surge. The stick buffered, failed, or guessed. Treat that shape as monitoring. Confirm it by the LCD photograph from the same hour, if you were home to take it, or by the next sunny hour you can stand there. Do not delete the day and do not type a replacement total. A wrong total edited in software becomes a second lie beside the first. The bill will not follow your edit. If you need a figure for your own notebook, copy the LCD and label it as the LCD, and copy the app and label it as the app. Two labelled numbers are allowed. One blended number is how arguments start.
A current sensor on the wrong conductor is the other liar, and it shows up as export the meter does not bill, or as import while the house was clearly sending power out. This page does not tell you which conductor to move, and it does not publish a map of the sensor. Photograph the app's export tile beside the LCD and beside the relevant bill line, and take the mismatch to the missing-export fault. Often that fault is the file or the sensor, not the plates. Say whether the file is a new net-billing file after 9 February 2026. Do not clamp a different wire because a diagram in a chat looked similar. The long app-yield guide explains the clue. A qualified person moves hardware. You move photographs.
Trust the LCD hour instead of editing the yield
No register edit, and no units certificate from the app
This page does not publish a Modbus map, and it will not name a register to write. Editing production so the app matches a hope, a brochure, or a dispute is refused. If the LCD and the app disagree, the LCD wins for the hour you can see, and the stick is the thing you repair. If they agree and both look low, the roof pages win and the app is innocent. If the app shows export and the bill shows none, the missing-export page wins. There is no fourth path where a hidden register is nudged until the three records match. Nudging one record does not change the meter. It only makes the next photograph harder to trust.
We will not certify your units. A buyer asking for a letter that the app's monthly total is the official production is asking for something this desk does not have. The meter, the bill, and the LCD photos are the record. Send those if you are in a dispute, and say they are photos rather than a certificate. The calculator's Rs 11 per kWh figure is only a labelled working rate on the calculator, not your tariff and not a way to turn an app total into money. September 2026 street bands live on the prices page, and no band is copied onto this fault. Do not multiply a fake app day by any rate and call it a loss. Establish the hour on the LCD first.
The app-yield essay stays canonical
The long guide is app yield. It stays canonical. This URL does not rewrite it into a second metering manual. You compare one sunny hour, you name the flow, you refuse a register edit, and you send a stick problem to the dongle page or a roof problem to soiling and MPPT. A bill that shows no export goes to the missing-export page rather than into an argument with the plates. Phone 0300 0465810 or email info@zarkaarpower.com with the LCD photo and the app photo of that same hour. Updated 2 October 2026. Say the tile labels. The desk will not reply with a corrected units total or a map of registers.
The decision on this app-yield URL is that the LCD wins for the hour you are standing there, a flat app day is a stick until both screens are low, and nothing is edited to force a match. That decision would be false on a page about a hot pack or a phase that went missing. The app-yield essay remains the long account. Four flows stay four flows. Net-billing bills after 9 February 2026 stay the filing record under SRO 251(I)/2026. No Modbus map appears here. If you only needed a bigger number, you will not get one from this stop.
| LCD at a sunny hour | App at that same hour | Next page |
|---|---|---|
| Healthy PV watts | Flat, or a later catch-up spike | Dongle and login, not the plates |
| Low, and the curve is real | Low | Shade, soiling, or MPPT |
| Little or no export | Export the bill does not show | Missing export, often the file or the sensor |

Questions
The app says I made more than the plates can. Who is wrong?
Photograph that hour on the LCD. A scaling error in the app is common. The plates did not break physics.
Can you certify my units for a dispute?
No. The meter and the LCD photos are the record.
The app shows a flat afternoon and then a sudden jump. Did the plates surge?
No. That shape is a stick that was offline and then drew a catch-up which is not physics. Photograph the LCD for the same hour if you still can, or stand there on the next sunny hour and photograph PV watts before you open the app. Do not delete the day and do not type a replacement total. Label the LCD figure as the LCD and the app figure as the app. The dongle page is the stick visit. This page only stops you treating the jump as production. The app-yield essay stays the long guide. A surge that exists only in the app did not happen on the roof.
The bill shows no export and the app shows export. Where do I go next?
Go to the missing-export fault with three pictures: the app export tile, the LCD for that period, and the bill line. Often the cause is the file or a current sensor on the wrong conductor, not the plates. This page does not tell you which conductor to move and it does not publish a Modbus map so you can edit the mismatch away. Say whether the file is a new net-billing file after 9 February 2026 under SRO 251(I)/2026. The bill beats the app. The LCD beats the app for the hour you can see. Send the set rather than clamping a different wire from a chat diagram.
How do I compare one sunny hour without treating the app as a second meter?
Stand at the inverter at noon and photograph the PV watts on the LCD. Then open the app for that same hour and photograph the tile, including its exact label, because import, export, PV, and load are four flows. Write both numbers and do not average them. If the LCD is healthy and the app is flat, the stick is next. If both are low, look at shade, soil, or the tracker. One hour is enough to choose the door. A month of app history is not a meter, and this desk will not certify it. The long guide is the app-yield essay. The LCD photo is the piece you can defend.
Can I edit a register so the monthly app total matches the LCD?
No. We refuse that edit. This page does not publish a Modbus map and will not name a register to write. Changing the app does not change the meter, the bill, or the energy the roof made. It only creates a third number that nobody can trust. If the two screens disagree, repair the stick or believe the LCD for the hours you photographed. If they agree and look low, read the heat, soiling, or MPPT pages rather than the register list. Send the photos to 0300 0465810 or info@zarkaarpower.com. Updated 2 October 2026. The reply will not include a corrected total.
September in Multan looks low against the STC sticker. Is the app lying?
Not necessarily. A hot month produces less than the brochure, and the Multan heat page is where that expectation is set. Judge September from the LCD on a sunny hour, not from an STC sticker and not from an app that may have been offline. If the LCD is also low and the curve follows the sun, you may be looking at heat, soil, or shade, which are honest roof reasons. If the LCD is healthy and the app is the only low figure, the app is the liar and the stick is the fault. Do not multiply either figure by the calculator's Rs 11 working rate and call it a loss. That rate is a labelled calculator figure, not your bill.
Which flows should I name so import is not confused with what the roof made?
Name four: PV for the roof, load for the house, export for units that left, and import for units the street sold you. Write the exact tile label from the app beside the LCD photo, and say which of the four you think you are looking at. A hero number with no name is how a healthy roof gets accused. If export on the app is missing on the bill, the next page is missing export, not a new set of plates. This stop-page refuses a register edit that forces those flows to match. The app-yield essay stays canonical. Trust the LCD for the hour you can see, and let the bill speak for the month.
