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%.
11.0 Troubleshooting Problems
How to Read this Section
Troubleshooting Problems
is split into three sub-sections, grouped by
symptoms involving key components. Components considered irrelevant
in a diagnosis are denoted ‘Not Applicable’ (N/A). A multimeter or
voltmeter may be required for some procedures listed.
It is imperative all electrical precautions stated in the
Warning Section and outlined in the Installation Section
are followed.
Even if it appears the system is not
functioning, it should be treated as a fully functioning
system generating live power.
11.1 Problems with the Display
Display Reading:
Blank
Time of Day: Daytime/Nighttime
Possible Causes:
Battery or fuse connection and/or solar array connection
(Daytime only) or battery or fuse connection (Nighttime only).
How to tell:
1. Check the voltage at the controller battery terminals with a
voltmeter and compare with a voltage reading at the battery
terminals.
