My voltmeter shows a different reading than the GP-PWM-30-SB
display.
The meter value on the GP-PWM-30-SB display is an approximate
reading intended for indication purposes only. There is an approximate
0.1 volt inherent error present that may be accentuated when compared
with readings from another voltmeter.
There may be a slight difference between the battery voltage displayed
on the GP-PWM-30-SB display and the battery voltage measured at the
battery terminals. When troubleshooting using a voltmeter, check both
the battery voltage at the GP-PWM-30-SB controller terminals and
battery voltage at the battery terminals. If a difference of more than 0.5
volts is noted, this indicates a large voltage drop possibly caused by
loose connections, long wire runs, small wire gauge, faulty wiring, a
faulty voltmeter, or all the above. Consult the Suggested Minimum Wire
Gauge chart in Section 5 for wiring suggestions and check all
connections.

Why does the battery SOC% never reach 100%?
A 100% value will only appear after a 30 min Boost at 14.4V 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%.
