Something strange happened the last few days. My pv Butler app shows battery discharge during full sun and very low load, maybe around 300w, but show battery charge at night with the same load ? The system is in Limpopo. I asked a friend to go look and inverter and batteries seemed fine. We are not home currently.

Any explanations ?

I attached the photo below to explain what I mean by that. Please look at the PV charge, load and "battery charge" numbers. Makes no sense to me. Anybody saw something similar ?

I may be way off , not being familiar with butler, but perhaps the timezone in your app is not set to your local time! Maybe an update caused a reset if it was correct previously.

Thanks Thunderbolt, this strange occurrence never happen for more than 6 years since installation. The app on the Google play store shows no updates. Yet the daily statistics does not reflect these strange battery discharge and charging indicators on the live screen.
