Solaredge: Changing "storage control mode" changes display mode in solaredge app

[ministryofsillywalks]

Not a bug from this application but something that caused me a lot of headache so I thought I'd comment here in case anyone else has this problem.

When changing the solaredge "storage control mode" from the normal mode of "maximize self consumption" (MSC) to anything else like remote control mode which im guessing evcc uses to control the inverter and battery the solaredge app on android and ios changes the display to a simpler version, not showing the detailed usage split between battery, import and direct pv usage.
(see the attached screenshots)
Normal Display:

"Broken" Display:

I wrote solaredge support about this and they said this:

I consulted some people in our QA, R&D and product team, currently, when taking the system out of MSC, the displayed is changed to the one you saw and it is set back when the MSC is set again.
Here is the answer from R&D and product:
“He changed the settings in a way that the site is not considered MSC. That’s why he lost the data (this is the current non-MSC display).
If he set it back to MSC properly then the data should appear for future days.
”
The product team set a development request and they are preparing the requirements to R&D so that the display will be kept.

I have no idea why they would disable detailed statistics in the app when changing away from maximize self consumption.
They seem to also agree that this shouldn't be the case and started working to fix it but he also said it would be more of a long term change.

Does anyone else using solaredge have this issue? Have you found a workaround?
Periodically changing the inverter back to the "maximize self consumption" mode seems to restore the data in the app (so it is being saved somewhere) however I don't know if there is a limit on how far back this works.

Maybe evcc can switch the inverter to "maximize self consumption" when nothing apart from the house/battery is charging? Then the app should continue to show the detailed statistics.

From my experience with Solaredge Inverters the control strategy is as follows:
1.) You have to enable TCP Modbus and the functionality for remote control via change of Storage Control Mode to 4. The available options are:
0 – Disabled
1 – Maximize Self Consumption
2 – Time of Use
3 – Backup only
4 – Remote Control

2.) Then a combination of Storage/Discharge default mode and Remote Control Command Timeout [s] becomes active. The available options are:
0 – Off
1 – Charge excess PV power only
2 – Charge from PV first, before producing power to AC
3 – Charge from PV+AC according to the max battery power
4 – Maximize export – discharge battery to meet max inverter limit
5 – Discharge to meet loads consumption.
7 – Maximize self consumption

If Storage Control Mode is changed from „1“ to „4“ to enable external remote control and Storage/Discharge default mode is set to „7“ your Solaredge internal control functionality remains unchanged as long as Remote Control Command Timeout is expired.

The timer starts to count with the last sent Modbus control command. Standard value is 3600s , one should use a shorter time to enable a fast fallback if something goes wrong (e.g. frozen or hung up Raspberry Pi or other device, or lost TCP connection for whatever reason).

I can also confirm the display behavior of the Solaredge app but this is kind of temporarily. The normal display data with full information is restored the next day. In may case the display for the day before yesterday (2May) just got restored this morning, while the data for yesterday and today is shown as what you describe with „broken“. Your display should be recalculated pretty soon.

I do not believe that this issue is linked to EVCC, this happens with any external control (e.g. ioBroker)

I also do not understand the statement from Solaredge support saying that you did something wrong. I found in an official Solaredge documentation the information that the full display data needs to be recalculated and is shown with delay. Solaredge hast to identify why a remote control is affecting the amount of displayed data in their monitoring system.

Thanks for your insight. Guess I will just leave evcc running for a while and see if the display does indeed recalculate itself after a day or two delay.
I was kind of scared to mess up my stats longtime.

@hijacker123
Please explain to me in detail how to change the "Storage Control Mode" to 4.

same here! A tutorial / short video would be really super helpful!
