Good morning Alshymer and Happy Christmas,

The Efoy monitors the battery state and will only turn on when the terminal voltage hits 12.3V, the solar panel will permanently be charging.

Working on this basis, then the Efoy will only kick in when the load on the batteries is greater than the solar panels can compensate for, which in turn will be more likely to happen in the winter months with the sun lower, and in colder conditions.

If i'm wrong, or anyone can add more please do.
