Can you Equalize Flooded 12V with Solar over a a few days?

The general consensus I read with off grid is there isn't enough sunhours to reliably EQ.
But for 12V batteries sitting on standby that get used a handful of times a year, can you simply run the EQ in mppt controller,
and then run again(re-continue) the next day? Assuming of course in between days the battery is not discharged.
My understanding is the amount of wattage/current needed is small to perform an EQ, like C/20 or less. Is this true?
ATM I have a Century 12V marine Deep cycle & the specifications seem to suggests an EQ every 3 months or so for a few hours at around 15volts+.
thanks

You can certainly equalize on solar alone! It may be a misconception that you can't because people often use timed absorb cycles. I usually pick a couple sunny days even this time of year, when days are short and I'll try to reduce loads at night as much as possible. It's very easy when we get 2 sunny days when I spend the night in town. Then by noon my batteries are fully charged and I can start a maintenance equalizing cycle.
Corrective equalizing can go on for days, and in that case, a generator is a bit easier, but I've never used one with my batteries and have been dealing with it okay.
- Assorted other systems, pieces and to many panels in the closet to not do more projects.
EQ is only done when needed
