Bug report: individual MPP operation mode reporting not working

Hi developers,

Multi RS Solar and Modbus TCP

MPP operation mode (general) 4543 reporting OK

MPP operation mode (individual) 4605, 4606 reporting NOT OK.

For example 4543 reporting 2 (MPP active) and in the same time 4605 and 4606 reporting both 0 (MPP off).

Hi @Alex Pescaru

In version 3.14, the MPP information per tracker is not available internally in Venus OS and then Modbus TCP returns 0.

Kind regards,

Hi developers,

Thank you for clarifying it for us.

Maybe on the "Document Versions" tab of the "CCGX-Modbus-TCP-register-list.xlsx" file, it worth mentioning, besides revision number, the minimum version of the Venus OS for those revisions to work.

Thanks again!

Alex

Hi @Thiemo van Engelen (Victron Energy staff) , @mvader (Victron Energy)

Kindly kindly please, can I ask you something?

On the future, can you please add one more state on DBus, for the "MPP Operation Mode" (/PV/x/MPPOperationMode), like "3=Scanning"?

In this way it will be easier on send_data() from vrmlogger, to handle the MPP scans and delay endpoint.send() during MPP scans, like you've done it on send_hourlydeltas()

Thank you!

Alex

Hi @Thiemo van Engelen (Victron Energy staff)

And if we are still here, also:

2901, ESS Minimum SOC is always reading 100 (10%) no matter what you set in ESS setting page at Minumum SOC.

2903, ESS BatteryLife SoC limit (read only) also reading all the time 100 (10%), even if is set to "WITH BatteryLife)

2900 ESS BatteryLife reporting all the time 1

2902 ESS Mode reporting all the time 1, no matter what you set in ESS setting

Thank you

Alex

LE:

Now I see that those above are "com.victronenergy.setings", not "com.victronenergy.multi" and as Multi RS has a "hybrid" ESS, then they don't have how to show correctly.

Still, can be reported and set?

Thank you again!
