Huge discrepancy between Solis data and meter reading

Just checked and mine was:

Meter imported 160 units

Solis imported 139 units

I would not blame Solis here as it is only reporting what the meter is reporting to it. You should have meter in your trip box with a clamp. This reports import/export data to Solis. So it could be that the problem is with the meter. Mine has LCD and I can check usage on it. See if you have something similar.

Hi,

Yes I have it as well

Glad someone else is seeing the same thing,

I have only newly installed the system (3 weeks) so I am watching it closely at the moment and this is something I noticed.

Although I expected some difference I didn't expect it to be in this direction e.g Solis app consumption being less than meter consumption. (I hoped it would be the meter reading less than Solis app)

There is still lots of other stuff I don't understand. Like why is my battery supplying the grid?

Came across this thread so checked my own readings.

My provider is telling me I've used 3100kw this year so far, Solis is telling me I've used 1600kw so there is a big difference over time.

I'm seeing differences in solis vs smart meter data also. Solis was showing 1kWh for this week and smart meter dashboard about 4kWh in total. Myenergi hub was reading about 5kWh.

I think perhaps the solis is ignoring anything below a certain amount but the little amounts do add up.

isnt one problem that the app seems to round down all of the KWh readings? 0.9KWh becomes 0 ?

new to solis cloud, still trying to find my way around .

Is there an easy way to zero the data in solis app or do I need to reset Wi-Fi dongle? Want to zero it/align it with my owl meter.

The inverter seems to use about 80 watts, so it’s an expensive way to measure power usage if that’s all it was doing.

I’ve to get the power meter replaced on mine as it was dead on arrival. Is there a special meter that only works with solis? I’ll also be installing a Shelly em at the same point.

Also, something folks might find weird is that the ESB meter is not accurate either. There is no true reading of what you consume, though obviously the meter is the best measure we have available.

I wouldn't worry about it. Id have to hark back over 15 years to give a half decent explanation.

Not sure if any conclusion was made on this , but does it mean that the Smart Meter is correct always and the SolosCloud app is just something that gives a ball park figure .

Like most here I installed Solar Panels on Oct 2022 and then the Smart Meter was installed on Nov 2023 . on Imported KWH I have a difference between Solis and Smart Meter of about +3% KWH imported on Smart Meter compared to the SolisCloud App. e.g Imported fro GRID showing 10.3 Kwh on Smart Meter , but showing 10Kwh imported on Solis App.

However difference seem to be more pronounced when comparing exported KWH, difference seems to be -30% in favour of Smart Meter e.g exported 10Kwh to the Grid showing on Solis where as the Smart Meter is showing 7Kwh.

I get the impression from what I am reading that the Solis app only tracks import/export KWH on an irregular basis. If this was the case then the exported KWH should be less that registered by the Smart Meter but it is the opposite.

Also I do have Solar Batteries if this makes any difference.

Not sure I follow you , Solis logs all information and stores in the Buffer/memory and then pushes all that info every five minutes.

Whether it is 5 minutes or 25 minutes (as long as the Solis memory/buffer is big enough to store that recorded data ) then it should push all the info .

Even if that were not the case and it lost some of the data for some reason, the amount of KWH exported to the GRID should show up as being less than what is shown on the smart Meter but it is not .
