AuxPSErr
Auxiliary power
supply error
F26
Auxiliary power supply is not within its expected operating range. The error clears itself after 1
second and the auxiliary power supply will attempt to restart.
HsOTErr
(Heat sink over
temperature error)
F55
Heat sink temperature has risen above 82°C (180°F) for 5 seconds. The error clears itself
when the heat sink temperature falls below 70°C (158°F) for 30 seconds.
SetupErr
F69
Multiple charge controllers connected to the Xanbus network have the same device number.
The error will clear when the operator changes the device numbers of the duplicate charge
controllers. The device number can be changed in the Multi Unit Config screen of the SCP.
OutputOVErr
(Output over voltage
error)
F70
24 V System: Output voltage has risen above 34.5 VDC for 1 second. The error clears itself
when the voltage falls below 32.0 VDC for 1 second.
48 V System: Output voltage has risen above 69.0 VDC for 1 second. The error clears itself
when the voltage falls below 64.0 VDC for 1 second.
OutputFastOCErr
(Fast output over
current error)
F71
Appears immediately when output current rises above 140 ADC. The error clears itself after 5
seconds. If the error is triggered three times within 60 seconds, then it trips F78, which must be
cleared manually.
OutputSlowOCErr
(Slow output over
current error)
F73
Output current has risen above 115A (Conext MPPT 100 600) or 90A (Conext MPPT 80 600)
for 10 milliseconds. The error clears itself after 5 seconds. If this error is triggered three times
within 60 seconds, then it trips F78, which must be cleared manually.
FanOCErr
(Fan over current
error)
F76
Fan current has risen above 1.3 A for 500 milliseconds.
The error clears itself when fan current falls below 1.1 A for 1 second.
InputOCErr
(Input over current
error)
F77
PV current has risen above 32 ADC (Conext MPPT 100 600) or 25 ADC (Conext MPPT 80
600). The error clears itself after 5 seconds and the unit will attempt to restart.
Heartbeat BMS
Lost
(BMS heartbeat
timeout)
F90
When in Heartbeat BMS Mode, the Li-ion battery BMS is or has been disconnected. The error
clears itself after the BMS is reconnected.
