I added a FOX ESS battery to my solar installation about two years ago and last November, I switched to Octopus Flux to use the battery to take advantage of the cheaper rates at night. I did this by using the mode scheduler with forced charge at night and forced discharge between 16 00 and 19 00. I have noticed that my Generation FIT reading meter has shot up. The generation statistic from the battery which the meter reads has a much higher value than the PV produced KWH. I had assumed that the Generation FIT readings (as opposed to the export FIT readings) were for the PV generated power not the KWH that passes through the inverter. Has anyone else encountered this? I am worried that the Generation FIT Meter may have been incorrectly setup. Any help gratefully received.
Do you have a schematic of the system ?, just trying to understand whether the Generation FIT has been there since you had solar installed or whether it is new since the battery system was installed, also whether the Fox system has been installed so the FIT meter see's the power feeding in/out.
If you are in doubt, might be worth trying a test when it's dark - watch the meter and ask your Fox battery to charge for a 10 minutes - see if that has any effect on the generation meter. Then repeat with the battery set to force discharge.
If that meter is being relied on to report FIT solar generation, it should not be affected by anything the Fox system does.

Thanks for taking an interest. The sequence of installations was that I originally just had solar panels and I was getting FIT engergy generation payments. Four years later I added the batteries and the inverter was replaced at that time. The attached pdf is the schematic.
I did a little experiment this afternoon and watched the generation meter at 1645 (i.e. after sunset here but when the system was in forced discharge mode). The meter was flashing and recording generation activity. The Energy Stats app for the same time yesterday (which was cloudy and rainy so little or no PV generation possible) recorded the following. The energy stats app suggests there was no PV generation but there was generation activity (presumably this correspondes to flow through the inverter, caused by the forced discharge). Thoughts?
