Does anybody know if SBFSpot works with the new SMA Sunny Boy 5.0/6.0 inverters? The first two out are the 5.0 and 6.0. All other inverters are soon to be replaced with similar units. Thanks.

Almost sure it works... if not I can make it work ;-)
On condition there is an ethernet/speedwire connection.

That sounds great. I'll try it out when my system goes online a few weeks from now. Thanks.

Greetings All,

I have a Sunnyboy 5.0 inverter and and am happy to report it mostly works with SBFspot. There are two items that don't look like they are reporting correctly...

1) Device Temperature
2) EToday (today's generation I think)

Also on the DC Spot Data only 2 of 3 possible strings are showing and Total Pdc is absent (i'm assuming that it should be present since there is a Pac reported). I'm happy to provide any/info needed to help update the code, just let me know how I can help. Below is the SBFspot output from my inverter.

cheers,

momanz:
I have two Sunnyboy 6.0's. Started off with Windows/SBFspot then went to a raspberry PI which seams much more reliable.

I don't think inverter temp is available with these units because if I log directly into the inverters no temp data is available. Too bad, I hope I'm wrong and it is somehow available. Let me know if you figure out otherwise.

String data. So are you using all three string inputs, A, B and C? If so, they should be reported. As you know the knew SB's have three string inputs. Maybe SBFspot is unaware of that.

By the way, how exactly did you get the inverter output that you displayed above? Thanks,

Hi Dave,

I have SBFspot running on an old pogoplug running debian linux, it's been rock solid so far. As for the inverter temp, I didn't think it was available either (it isn't shown in the web interface) ; however, I've been experimenting with reading parameters from the modbus interface and I've found that there is an internal temperature register. My inverter is currently running at 48.2C :-). I'm hoping the good folks at SMA add the temperature to the web UI.

Curiously enough, the modbus registers for daily generation doesn't report a value even though the web UI does. The register is there, but the value is incorrect.

I'm actually using 2 of 3 strings, I thought maybe the line for "DC Spot Data String 3" should be shown since there is a line for the String 3 under AC spot data. Not a big deal for me, but as more of these inverters are installed someone may need the third line.

try the -v flag to get the output above.

How are you connecting to your inverters? I've found the integrated wifi to be less than stable. SMA has pushed one firmware update since my inverter was installed which improved the stability a bit, but in the end I decided to use powerline ethernet to connect to one of the ethernet ports.

cheers,

I wasn't aware of inverters having 3 MPP, so that's why SBFspot doesn't report the 3rd string. This makes the change more complex because it needs a csv and db change (Spot Table) so this has to wait for version 4
Temperature isn't reported by all inverters (at least for data2+ protocol), however EToday should be retrieved correctly.
Feel free to send me (s.b.f(at)skynet.be) a debug log so I can have a closer look.
The command to use is SBFspot -d5 -v5 -finq -nocsv -nosql -am0 -ae0

Hi SBF,

Log is on its way. Thanks for taking a look at this.
