Hello everyone. Does anybody use the Solis Cloud App and do they find it accurate ?
I’ve been trying to get to the bottom of this .
I have checked several sample days through three methods:
1. ESB Networks ( my account)
2. My supplier ( Bord Gáis ) export details supplied on spreadsheet .
3. My Solis Cloud App

For example these are the readings for 26.4.26 :

ESB Networks:
Energy Consumption: 8.6
Exported to grid : 10.8

Bord Gáis Historical Export Data :
( Just gives that day’s export to grid details ) : 10.828

Solis Cloud App:

PV (day )
Self Use : 12.02
PV to grid : 5.88

As you can see above the ESB and Bord Gáis figures match as do several other sample days I have tested.

However the Solis Cloud App gives totally different figure .

I know for certain that ESB and Bord Gáis are spot on as I have three previous Bord Gáis and the microgeneration credit has been spot on .

Is there a glitch in my Solis Cloud app or am I reading something wrong?

Thanks in advance.
 
Last time I looked into it, i think Solis only take snapshots at either 1 or 5min intervals (depending on your settings)
 
Could it be an issue with the CT clamp that feeds the export data to the Solis App? If this is not installed correctly on the line out it could distort the figures?
 
just checked and the figures are reasonably close comparing Solis to ESB for me. For 2025 the difference is about 1%
 
I'd check this with your installer as it is very much dependent on where it is situated. If in the Consumer unit I wouldn't advise you checking it yourself as this could be dangerous and against regulations.

The main issue is where the clamp is attached to the wrong cable out. It should be on the hot (live) cable.
 
Spot on Voice of Reason. I contacted my solar installer and appears my “CT clamp was giving the wrong information to the app.” .
Sorted now going forward. Thanks for all the replies. Case closed.
 
And just an update here , the app is now working perfectly. Must be more users with this problem and it was such an easy fix / quick email reply. Thanks again.
