PROBLEM
CAUSE(S)
DIAGNOSIS
REMEDY
Battery voltage gets
too high.
PowerCenter regulating
voltage set too high
Excessive battery gass-
ing. Use voltmeter to
check battery cell vol-
tages or hydrometer to
check the specific gravi-
ty – compare to battery
manufacturers recom-
mendations.
Adjust battery regulation
voltage as on page 9
During operation without
dump load, battery vol-
tage can vary up to 1
volts above reg. voltage
for a few seconds when
in Slow Mode
Use multi-meter to indi-
cate battery voltage
Normal operation, OK
for flooded lead acid
batteries. For sealed
batteries recommend
adjusting the set voltage
lower, or use a dump
load which will allow
very precise regulation
Batteries do not reach
full state of charge.
PowerCenter regulating
voltage set too low.
Use hydrometer to
check the specific gravi-
ty of the battery cells.
Compare with battery
manufacturer’s recom-
mendation.
Adjust battery regulation
voltage as on page 9
Loads are too large.
Remove largest load. If
battery bank reaches
higher state of charge,
then the system is over-
loaded.
Consult with BWC about
possible remedies.
