Why does the battery SOC % never reach 100%?
A 100% value will only appear after a 2 hour Boost or Equalize charge
has completed. The charge voltage must be maintained for an extended
period of time to replenish the energy in the battery bank back to its rated
capacity.
If the charge voltage cannot be maintained continuously, then the actual
time it takes to complete Boost or Equalize charging may take much
longer than 2 hours, even more than 1 day.
If loads are consuming more power than the solar panels can supply,
then the battery bank cannot be charged to 100%.
