There are some references to equalizing charging in the Renogy PWM 10A/20A manual, but I can't figure out if that's something I can make happen or if the controller decides when to do it.
It also says there should be no load on the battery when equalizing (I assume to protect electrical devices from over-voltage?), so if it turns out that the controller decides when to equalize how would I know so that I can ensure no loads?
I have one group 24 dual-purpose marine/RV 65 Ah flooded battery on my sailboat, with a Ganz 55w panel and a Ganz GCC-D10A controller, which appears to be a re-branded Renogy PWM 10A dual-battery controller. There is currently no battery connected to the #2 output of the controller.
I also have the MT-1 Tracer Meter installed.
Thanks for any insight into the equalizing procedure/process.

Yes your battery does need to be Eq once a month... I never unhook my loads I think it equalizes better.... Don't worry the CC will keep the devices from over charging.... Are the devices attached to the load side of the CC?

The equalization voltage is not likely to do harm, it is generally set too low. What does the manual suggest as the eq voltage?
Controllers with no clock/calendar generally can not force equalization.
When you find the controller's flooded equalization voltage, compare it to the battery makers recommended charge voltage.

The charge controller manual says that the equalization voltage will be 14.6v for flooded batteries. I haven't found the spec. yet for my particular battery, but it's just a group 24 dual-purpose marine/rv battery, so I don't expect it has any very special requirements.
But what I really want to know is how does this charge controller decide when to equalize? How will I know if it is equalizing? Or how do I tell it I want it to equalize?
The charge controller manual never answers these questions, even though it mentions equalizing in several different places.
