SBFspot using with a SUNNY WEBBOX - Configuration

Jun 30, 2014 at 1:13 PM
We run a 29.6 kW PV System and I look for a nice and runnable system for a Raspberry.
The panels are performed in two SMA SUNNY TRIPOWER 15000TL. The inverters are connected to the SUNNY WEBBOX with SMA RS485 interface data module. The Webbox is connected to our network via a router and has the fixed IP address 192.168.2.60 (and Port 80)

I installed the SBFspot on my RPi and get it to run, but I couldn't get a connection to the WEBBOX. In the smaspot.cfg I deleted the BT entry and put in the IP-Adress. After I compiled the app it runs, but with the following message:
pi@raspberrypi ~/smaspot/bin/Release $ ./SMAspot -v -u

Is 192.168.2.60 the correct IP?
Please check IP_Address in SMAspot.cfg!

How can I get the WEBBOX to run with SBFspot?


Thx

Volker,

It won't work. SBFspot does not support the SMA Webbox.

The SMA Webbox does create CSV files for the connected inverters.
You can retrieve these daily files using a simple FTP client.
There is also a FTP push functionality ( the Webbox can push its CSV/XML files to a Raspberry directory )

There is also a RPC functionnality to retrieve data at a faster pace.
Can be very incomplete / buggy depending on the inverter model
( is useless with HF inverters eg )

Tridgell is using RPC

192.168.0.28 is the IP of my Webbox
Some data channels are not available (see GetProcessDataChannels result) : eg Uac, Iac.
SMA is aware... and they don't care.

It might different for a TL, or not :)

The richer set of inverter channels is from SBFspot.
The Webbox CSV files provide the same set minus some status fields, and minus inverter temperature.
