Need assistance with calibration

Greetings folks

I need some assistance in tuning my flukso so that the readings are accurate.

I have adopted the same setup as bazzle with the Lynx pulse meters (2000p/kWh - constant 2) and then configured PVOutput accordingly for each of the two inputs. However PVOutput is reading about much higher than expected.

Any idea what I need to do to get the readings accurate?

TIA for assistance.

What I really need is to read the manual. Found the right figure thanks.

Well done :)

I blame you bazzle for supplying the inspiration to do this. ;) Unknown to you, your contributions on the Rowtel blog is what got me started.

The flukso installation is proving very useful and even though we haven't had much sun this week, its been interesting in getting a grip on power consumption in the house. Well worth doing. The previously installed energy meter is now gone since after a few days it was obvious it was not accurate at all.

Since I put in the correct calibration figure, the inverter monitoring and the flukso readings have been close enough that it doesn't matter as expected.

And just for interest sake, the setup below. The separate inverter monitoring is the black box on the inverter and the flukso in its housing on the wall. The lower images are the meters in the meter box. A short run of cat 5 between them is terminated on an ethernet jack just to keep it neat.

The inverter monitoring is an RS485 to wifi adapter terminating on the LAN which means the inverter can be monitored from any device on the network. This is forwarded to PVOutput.
