MPPT 'wake-up' mode skipping days?

More curious than anything, as the system seems to be working OK… but I recently noticed that my VRM data does not show that my solar controller does not go into “wake-up” status consistently each morning. In the last 12 weeks, it has maybe 10 times. Batteries charge as they should, and other mppt modes seem to be cycling through as expected. What would cause the wake-up mode to be ‘skipped’ like this?

VRM takes a snapshot of the system status every so often, not continuously, so it may miss seeing the wake-up status as the mppt is only in wake-up for a short time.

This is quite normal. :slight_smile:
