TROUBLESHOOTING:
A.
The lights on the solar controller look fine but the batteries
aren
’
t charging?
The solar voltage must match or exceed the
battery voltage. Check to make sure Solar Panels are wired cor-
rectly.
B.
There is no voltage output?
If battery voltage is too low the
charge controller will turn off the load outputs. This typically hap-
pens when battery voltage falls below 11V for 12V systems, 22V
for 24V systems and 44V for 48V systems.
C.
Why is my solar panel voltage so high?
Open circuit voltage
on a 24V panel is around 40V and 80V for a 48V panel. Once
you connect to the charge controller the panel voltage will be re-
duced.
D.
My system turns off at night and comes back on in the morn-
ing?
This is a sure sign that the solar panels and/or battery ca-
pacity can
’
t support the load. You should measure your actual
load and recalculate to make sure you have adequate solar and
battery capacity. Make sure there is no shading of solar panels
during the day.
E.
There is no power at the solar controller?
Check the battery
cable fuse. Measure battery voltage at the solar controller it
should be >10V. If less than 10V then batteries will need to be
charged with an external charger to bring the voltage up to normal
operating range of the controller. When batteries are in an array,
need to charge each battery individually. A 12V battery will meas-
ure 12V or higher when adequately charged.
