Solaredge Inverter data clearly not represented at PVOutput correctly

Problems
#1

I carefully monitor our PV system output. On the whole, PVOutput’s representation of it was good. Today, however, contrary to every other independent report I have, PVOutput is understating our generation, beginning about 1130 local Daylight Savings Time (East Coast, USA). I don’t know what’s going on.

But by subscribing to a solar data aggregator, I think basic accuracy is something that’s perfectly reasonable to expect.

I’m shopping around for another.

#2

You have the solaredge energy option enabled, this will retrieve energy data from solaredge in 15-minute intervals.

Disabling this will use solaredge 5-minute power data.

The data will be only as accurate as of that provided by the SolarEdge API.

#3

The solar edge data started showing only 1 inverter 2 days ago. So PVoutput is showing 50% of what my system is out putting. Solaredge site shows both inverter and the correct total. I am not sure if the problem is with PVoutput or Solaredge.

#4

It is downloading from both inverters and adding up totalActivePower

05/Jul 8:00PM
PVOutput = 43W
Inverter 1 = 21W * 1.015
Inverter 2 = 22W * 1.015

05/Jul 7:45PM
PVOutput = 254W
Inverter 1 = 125W * 1.015
Inverter 2 = 125W * 1.015

Thank you! I have changed it.

My setup is so, but not accurate. On average, a deviation of 0.5 kW per day.
