Thermal derating is
indicated on the SCP.
A. The charge controller is operating
in a high ambient temperature
environment at high power levels.
B. The fans are not working properly.
A. The charge controller is specified to
operate at full output power up to
45°C. Derating occurs at temperatures
above this level.
B. Make sure that you have not
blocked the ventilation holes at the top
and bottom of the charge controller
and that you have provided sufficient
clearance for proper ventilation of the
charge controller. Check the active
fault list and the historical fault log on
the SCP to see if the charge controller
has registered any faults or errors
related to fan operation.
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 A–
2 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 3–2 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 Conext MPPT
80 600 Solar Charge Controller power
supply during the night.
See “Reducing Tare Loss” on
page 2–19 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”
on page 3–7) 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
problem is not resolved.
