Multiple SMA inverters (LAN)

Aug 22, 2014 at 12:02 PM
Hello,

Could someone please explain to me how to make this work with 2 inverters in our home? Both connected to LAN. I tried adding 2 ip adresses in smaspot.cfg but that doesnt work. If i remove all IP's (#) it only recognises 1 of them. Any idea?

Thank you, an example would be really appreciated.

Unfortunately, SBFspot doesn't work with more than 1 inverter via LAN. Ssome people managed to change the code to let it work, however it is not yet officially supported.
For now, the best way is to create a config file for each inverter and run SBFspot for each config (with -cfg parameter)
A drawback of this method is you don't have a combined view in the CSV files and on pvoutput.org
Hope this helps

Hi,
This problem may be solved by using the PVOUTOUT system aggregation feature. Simply set up three systems, two child systems and one parent. The documentation is on PVOUPUT.org

Sorry but where do you find this info on pvoutput.org??

Hi,
Here is the link:

http://www.pvoutput.org/help.html#general-aggregation

You will need a SBFspot configuration file for each pvoutput child system you create. In each configuration file will be the IP address of an inverter and the system ID of child system you want to associate with that inverter. The data will be fed to pvoutput on a per child basis and then using aggregation facility of pvoutput, will be combined in the parent system you have configured.

When i try to run it with -cfg i get:
./SMAspot -cfgSMAspot1.cfg

Very cool but i cant add more then 2 (in order to setup 2 systems it seems i need another purely as parent but thats 3), then i need donation mode.

Hi,
I did not realize system aggregation was a donation mode feature. I have been in donation mode for so long I really don't think about what is and is not a donation mode feature. Pvoutput is a great service. You might want to think about making a donation. I have been using it for 2 1/2 years and have experienced perhaps two or three issues in that time with the service itself.

Does it produce the output files? If so, I wouldn't worry about it.

Try also the other options like -v (-? For help)
