Issue Possible Cause Solution
Battery voltage is
exceeding bulk and
float settings in cold
weather and not
reaching settings in
hot weather.
The BTS is compensating charging
voltages based on battery temperature.
No problem. This is the intended operation.
The charge
controller’s Error/
Warning (red) LED
is on or flashing.
An active fault, error, or warning is
present on the charge controller.
See Viewing Active Faults, Errors, and Warnings on page
48 to determine which alarm is active on the charge
controller. The tables in this section provide detailed
information on why various alarms could be occurring on
the charge controller.
Battery equalization
was enabled but did
not occur.
The charge controller must complete a
bulk/absorption cycle before it can initiate
an equalization cycle.
See Equalizing Batteries on page 55 for information on
equalization charging. See Viewing Status Information on
the Charge Controller on page 44 for information on
determining the status of the equalization cycle.
BTS information
does not show up
on the charge
controller’s Meters
screen on the SCP.
The BTS reading is only shown on the
Meters screen if the BTS is physically
connected to the device you are viewing
on the SCP. All devices share BTS
information, but they only report the
information to the SCP if they have the
BTS plugged into their BTS port.
Navigate to the Meters screen on the SCP for the device
that has the BTS connected to it.
Thermal derating is
indicated on the
SCP.
The charge controller is operating in a
high ambient temperature environment at
high power levels.
The fans are not working properly.
The charge controller is specified to operate at full output
power up to 40°C. Derating occurs at temperatures above
this level.
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.
