I have now got a few months worth of data collected from my system using two different upload methods:
- PVOutput Donator-based service. More or less correlates with data from www.solarweb.com.
Settings: Fronius Daily Log
SolarAPI v1 - Logdata - Data by HTTP POST every 1h / pvoutput.org:80 /
- PVOutput free service (same inverter, different settings, does not correlate with (1) or www.solarweb.com).
Settings: Inverter to PVOUTPUT
SolarAPI v1 - CurrentData - Inverter by HTTP POST every 5m / pvoutput.org:80 /
Settings: Meter to PVOUTPUT
SolarAPI v1 - CurrentData - Meter by HTTP POST every 5m / pvoutput.org /
There are discrepancies between the datasets - more or less, once the system starts generating power
the power used figure in the free system (2) is wrong. I have experimented with various settings on (2) to try to bring it into line with (1) without success.
Am I doing something wrong, do I need to update firmware, or is this a bug (‘feature’)?
The meter is the generic modbus “Fronius Smart Meter” I think the model is a 63A-3.
Is it possible to get this meter and inverter combination to show solar data correctly on pvoutput.org using the onboard settings and a free PVOutput account (if so, how?), or is it never going to work properly unless my status is ‘Donator’?
