PROBLEM
CAUSE(S)
DIAGNOSIS
REMEDY
PV is not on, even
though sun is shining.
Dump load at 97% ca-
pacity or higher
Turn on additional loads
to pull down battery vol-
tage. See if PV turns
on.
Normal operation.
PV hooked up back-
wards.
Check polarity.
Reverse leads.
PV fuse blown.
Check fuse with VOM.
Replace fuse.
Dump load does not
work.
Fuse blown.
Check fuse with VOM.
Check resistance of
dump load, should be
no less than 1/2 ohm.
Replace fuse.
Voltage below regula-
tion.
Check battery bank vol-
tage with VOM. If it is
below regulation voltage
(“TEST1” x 10) the
dump load should not
be coming on.
Normal operation.
Dump load comes on
during automatic ge-
nerator charge, pre-
venting the batteries
from taking a bulk
charge
Dump load set to come
on at 28.1 Volts, Inver-
ter set to bulk charge
batteries at a higher
voltage
During charge, battery
voltage limited to 28.1
V, Extra Load LED lit
Manually put Power-
Center in Equalize
