GP-BOOST-50/12
Error
Incorrect battery volt-
age.
The solar controller
does not charge.
Controller does not
seem to be charging
despite of sunny
weather.
EN
LED indication
Battery LED is on.
Solar LED is on.
Solar LED is on.
The Controller LED
will flash if controller
is charging. The Con-
troller LED is on con-
tinuously if controller
is not charging or if
there is insufficient
solar voltage.
Cause
Battery voltage is too
low because of exces-
sive voltage drop from
battery bank to control-
ler or insufficient solar
power.
Battery voltage is too
low because of exces-
sive load power draw
from battery bank.
Battery voltage is too
high because of sec-
ondary charging source.
Battery voltage is too
high because of a short.
Solar panel voltage is
greater than 85 V.
Solar panel current is
greater than 20 A.
Current is being limited
as per normal operation
or poor connection
between solar panel
and controller.
Troubleshooting
Remedy
Check all wiring and connections
from the controller to the battery
bank. Ensure that all connections
are clean and secure. Shorten the
distance from the controller to bat-
tery bank or obtain larger wire. It is
also possible to double up the
existing gauge wire (i.e. two wire
runs) to simulate a larger wire. Wait
for system to charge battery. Turn
off loads for faster charging.
Increase the battery bank capacity.
Consult your dealer or installer for
assistance.
Remove any secondary charging
source. The controller will only
begin charging after battery volt-
age has fallen to a normal level. Use
a voltmeter to check if voltages are
in correct range.
De-energize system and discon-
nect equipment. Use a DMM with a
connectivity setting to check for
shorts in wiring or equipment. Oth-
erwise, use a voltmeter to check if
voltages are in correct range. Con-
sult your dealer or installer for assis-
tance.
Measure solar panel voltage.
Change solar panel wiring configu-
ration. Consult your dealer or
installer for assistance.
Check solar panel nameplate for
ratings. Change solar panel wiring
configuration. Consult your dealer
or installer for assistance.
With the solar panel in sunlight,
check the voltage of the solar panel
terminals with a voltmeter. Check
all connections from the controller
to the solar panel including check-
ing for correct wire polarity. Check
that all connections are clean and
secure. Wait 5 minutes and recheck
charging status. A delay is present
to prevent erratic behavior.
