question

Anyone ?
If there are two PV-Inverters, on on AC-IN side and one on the AC-OUT side, how t get reliable data from them ?

Hy Philip,
I've quite the same problem, i have 2 PV-Inverters (Kaco Powador over RS485 own driver) on the Grid side. The Remote Console Sums up both correctly in the VRM Portal i can retrieve Information of both but in grafana i just have the /pvintverter path which directs to one of my inverters only.

Currently i didn't find a solution.

Off - Topic:

Maybe you can help me out, i cannot get my inverter connected to the grid line in the Overview like yours. Would you mind sent me your outputs of

dbus -y

and

dbus -y com.victronenergy.pvinverter.XXXX / GetValue

where XXXX is your grid connected inverter (see path in 1st Command output)
best regards

Michi

Servus Philip,
i found the solution in the Manual

https://github.com/victronenergy/venus-docker-grafana#queries---where

You just have to ad an WEHRE clause to the Query with instanceNumber = xx

The Instance ID you find in the RemoteControl settings of your inverter or just hit the dropdown menu and select the valid ID

Hope this works for you also

Regards

Michi

Michi,

To get the inverters in right place you need to determin which one is where in the:

Settings > PV inverters > Inverters > "name of your inverter" > Position > and Select from AC Input 1 / AC Input 2 / AC Output

Michi,

Your solution works great, thanks !

Meantime I've also found some part of the solution --> in grafana you can also make a query to the ones below:

system/Ac/PvOnGrid/L1/Current
system/Ac/PvOnGrid/L1/Power
system/Ac/PvOnGrid/NumberOfPhases
system/Ac/PvOnOutput/L1/Current
system/Ac/PvOnOutput/L1/Power
system/Ac/PvOnOutput/NumberOfPhases

like:

SELECT mean("value") FROM "system/Ac/PvOnGrid/L1/Power" WHERE $timeFilter GROUP BY time($__interval) fill(null)

I found those as measurments in my Influxdb database and they do work. To get these, log on to your OS where your influxDB is using SSH and type:

influx #--- to get into InfluxDB commandline
> SHOW DATABASES
> USE "here type in your venus databse you use"
> SHOW MEASUREMENTS --- this will plot the list of all available options
> EXIT

The system Values are interesting too thank you.

Thanks for the tip with the Position i already tried around but problem was the system Type.

Regards Michi
