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.
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.

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.
BattUTWrn
(Battery under
temperature
warning)
W9 Battery temperature has fallen below -20 °C (-4 °F) for 10 seconds.
The warning clears itself when the battery temperature rises above
-10 °C (14 °F) for 10 seconds.
Input over
voltage warning
(InputOVWrn)
W11 This warning follows the same curve as the Input over voltage
error, but it triggers 10 V lower. The warning clears itself when the
voltage falls to the input over voltage restart value – 15 V for 1
second. The input over voltage restart value is Vin Restart
Threshold in Figure 3-2 on page 3–10.
