Hi brulaz,
The batteries in question are sealed surplus acid AGMs so gassing voltage needs to be avoided.
I used to trigger equalization late in the day.

Never thought elevated voltages (upto 14.8V Vabs) to be much of a problem as long as you watch the water in the batts.
Our MPPT can stay in Abs and over 14V for long periods when we're using much electricity during the day. Also it's easy to force into mppt mode, which I'll often do late in the day to get batteries as full as possible before night fall.
