Installed my new emontx/emonbase yesterday and getting to grips with the logging.
I have three PV systems so have three CTs. Currently I have a hybrid logging system using legacy CurrentCost uploading to PVOutput but the plan is to replace this with the Emon kit and add additional functionality.
Noticed an issue last night whereby the feeds were showing power when the PV clearly wasn’t generating.
I have all the CTs oriented so that generation is positive.
The feeds are configured as (Allow positive / Log to Feed / Power to kWH) which I though would solve the issues of the low power to the inverters during darkness but for some reason the Log to Feed is showing a low positive reading (cf 5 to 10 Watts).
Is this just a function of the CTs/Power Factor?
Any suggested solutions? I guess sticking a ‘min value allowed’ after ‘allow positive’ to filter out the noise?
PS any pointers on how to get three feeds uploading to PVOutput would be welcome. I’ve found some source code in the forum but need to work out what it is doing yet.
