The PD will equalize every 21 hours of non use of the battery.
The Iota will equalize after every 7 days of non use of the batteries
This doesn't matter to the Iota the way you want to use it. I don't know about the PD but in the Iota the boost and equalize are the same voltage, 14.75V. If the battery voltage drops below 12.8v the Iota goes into boost, regardless of elapsed time.
If you let your battery get down close to 50% then fire up your generator, the Iota will detect the battery voltage is below 12.8V and charge the battery to 14.75V every time. If you want more equalization time, unplug the Iota from power, let your battery rest below 12.8V and plug it back in.
Someone can chime in on how the PD behaves in this scenario.
