The charge
controller’s Error/
Warning (red) LED
is on, and the SCP
indicates an input
over voltage error
(F9) for the charge
controller.
The PV panels are producing voltage
levels that are outside the operating
specifications for the charge controller.
This is likely due to the panels
experiencing extreme cold temperatures
for the region.
This condition will correct itself when the panels warm up
and the voltage decreases to within operating
specifications. If it occurs regularly, then the installation
likely has too many PV panels in series and might need
reconfiguration to lower the voltage to the charge controller.
See Electrical Specifications on page 64 for details on the
charge controller’s operating range.
The charge
controller’s On/
Charging (green)
LED is flashing.
The charge controller is outputting
charge current.
No problem. This is intended operation. See Viewing Status
Information on the Charge Controller on page 44 for LED
status information.
The SCP turns off
completely after
sunset.
The SCP is powered by the output of the
charge controller, and it has been
configured to turn off the Solar Charge
Controller power supply during the night.
See Reducing Tare Loss on page 42 for more information
on
disabling certain power supplies at night to reduce night
time tare losses.
The charge
controller's Error/
Warning (red) LED
is on, and the SCP
is blank.
The network power supply fault (F82) has
been triggered and has disrupted power
to the SCP.
Remove power to the charge controller by opening the PV
and battery disconnects long enough for the red and green
LEDs to turn off. Restore power by closing the PV and
battery disconnects, and then confirm that the SCP resumes
operation.
Contact customer service if the issue is not resolved.
The system is very
slow to respond,
does not update
data, takes a long
time to start unit
when applying PV
voltage.
Low Power (Night) mode is selected and
PV voltage at the unit is low (below
195V) or disconnected. In this case the
unit wakes up to check PV voltage and
transmit data on Xanbus once every 2
minutes and goes back to sleep if the PV
voltage is still low.
Low power mode is enabled by default from the factory.
This mode can be disabled under Advanced Features on
the SCP. When disabled, the unit will remain awake and
responsive as long as battery voltage is present. Note that
this increases power consumption at night.
