pvoutput made a change that addbatchoutput has been deprecated and replaced by addoutput but batching is only possible in donation mode, see https://forum.pvoutput.org/t/changes-in-addbatchoutput-jsp-related-to-donation-mode/4461 and https://pvoutput.org/help/api_specification.html#add-output-service

Hi there,
I just noticed on pvoutput.org that somewhere early 2019 it no longer logs temperature. It would be around the time I migrated to a new version on my Pi (saj_collector-0.5.2 -> saj_collector-0.5.8).
To be fair; I haven't downgraded to see what happens.

The inverter's website is still displaying temperature; the XML also contains it.

Anything I can do to help troubleshoot?
Or did the pvoutput.org API change? (I'm a donator, since I also log consumption)

Just had a new PV system installed last week. saj_collector did its job wonderfully, first time!
Only issue is when there are connectivity issues (flaky Powerline), I lose some stats, ah well.

However, saj_output_collector appears to be using generation stats off by factor 10?

$ cd /etc && ruby /usr/local/bin/saj_output_collector

Inverter info:

Model: | Sununo Plus 2K
Grid Compliance: | C10_11
Maste Control Firmware Ver: | V1.050
Slave Control Firmware Ver: | V1.050
Display Board Firmware Ver: | V1.125
Ethernet Module Firmware Ver: | V1.018

Would be a good thing to have some unit tests which validate that a certain SAJ input xml results in the expected calls to pvoutput, the tests within the pvoutput gem could help with this

Dear Johnny,

I have a SAJ 3KM solar inverter.
I have noticed you have this interesting project to connect to the inverter. I wonder how you connect to the inverter. I only have an RS232 module. Did you buy an extra ethernet or wifi module to connect ? I am puzzled to figure out the right RS232 parameters.

Could you give me some more details ?

Thanks !

Paul
