I wont upgrade to an os running 3b+ since i lack time and currently have to spend it on other stuff. I Will though create an image to v4 instead since 3b+ now is old Smile

hello daromer
i have a error cant fatch data from inverter if i manual applie command and after some time its shows like this

Nothing responds on that port. Either no inverter on that port of wrong protocol.

What do you have in 
ls /dev
 ?

Daniel I saw that the version of Grafana in your iso is 4.3.2 and the lastest version is 6.2.5 is it safe to upgrade to the lastest version ?

Safe to upgrade no idea. I have not tested it straight of on that ISO.

On rasp V4 the new version will be there.

I will make a backup of the sd card before ^^
I have done a graphic for my daily consumption from Grid (2 stacked kWh for my 2 inverters ) and at every refresh (1m) sometimes the both values are displayed ans sometimes only one is displayed, do you know where that could comes from ?

Sometimes this :

   

Sometimes this :

   

The queries :

Hmm. Takes to Long to query the database perhaps? Look at the debug. It might be timeout in the background causing it not to show. You can potentially aggregatet that data in the background to a new serie that is smaller and is faster to query

Its just a Guess though.

Hey everyone!
I'm pretty new in here and just got my system to work.
I use a Voltacon CONVERSOL OFF-GRID SOLAR INVERTER 1.5KVA DUO MPPT 12V. I run it with the PIP service.
The only problem I have now is that I don't get all the informations I would like to see.
As you can see in the attached code I don't get the PV Voltage and some other Informations that are available with some other software like watchpower.
Now I would love to know if it is possible to just change the calls.json file and fill it with the correct commands (I also don't know where I can get the correct commands)
 Or is there any other way to find out what I need to send to the inverter to get the wanted informations.

I have already tryed to modify the calls.json file but it just made it worse. The information that is now shown as ac_charging_current was before the device_status....

The calls.json file in /energy-logger/solar-sis/exam
ple/PIP4084/ contains the following code:



Code:
sudo systemctl status solar_pip.service -l

Is it enough to change the general status part or do I need to digg deeper.

If someone else got a Voltacon Inverter running successfully I would appreciate the calls.json file or any information on how to change the settings to get all informations.

Kind Regards
Luka

You need the protocol specification for that inverter or someone that can confirm how it looks. Hope some One can help you

Okay thanks for the information. So I guess there is no list available what protocoll to use for my specific inverter. Hopefully someone else can share it with me.
