Warnings
Table 3-6 lists all possible warnings. Warnings indicate that one of the charge
controller’s operating parameters is approaching the specified limits for the
device.
OutputFastOCErr
(Fast output over
current error)
F71 Output current has risen above 117.5 ADC. The error clears itself
after 5 seconds. If the error is triggered three times in a span of 30
seconds, then it must be cleared manually.
OutputSlowOCErr
(Slow output over
current error)
F73 Output current has risen above 90.0 ADC for 10 milliseconds. The
error clears itself after 5 seconds.
FanOCErr
(Fan over current
error)
F76 Fan current has risen above 1.6 A for 20 milliseconds.
The error clears itself when fan current falls below 1.0 A for
1 second.
InputOCErr
(Input over current
error)
F77 PV current has risen above 25 ADC. The error clears itself after 5
seconds.
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.

BattOTWrn
(Battery over
temperature
warning)
W4 Battery temperature has risen above 50°C (122°F) for 10 seconds.
The warning clears itself when the battery temperature falls below
45°C (113°F) for 10 seconds.
AmbOTWrn
(Ambient over
temperature
warning)
W5 Ambient temperature inside the charge controller has risen above
70°C (158°F) for 10 seconds. The warning clears itself when the
ambient temperature falls below 65°C (149°F) for 10 seconds.
