The Batt Under Volt (Battery Under Voltage) Fault
appears when the battery voltage falls to the nominal
battery voltage, minus 4 V per 12 V (for example, below
32 V in a 48 V system) for 1 second. The fault clears when
battery voltage rises to the nominal battery voltage, minus
3 V per 12 V for 2 seconds. You can also clear this fault
manually, except when battery voltage falls below the
minimum solar charge controller operating voltage of 10
V.
The Battery Under Voltage fault notifies you if the solar
charge controller is configured with the incorrect battery
voltage.
If this fault appears, check that the Battery Voltage setting
is correct for your system. If the Battery Voltage setting is
incorrect, correct the setting under the Battery Menu.
When battery voltage is set properly, the fault will clear
itself.
If the Battery Voltage setting is already correct, then the
batteries are excessively discharged. In this case, you
can manually clear the fault and let the solar charge
controller charge the batteries when sufficient solar power
is available. You can also shut off any loads connected to
the system and charge the batteries with another charger.

Output Over Current Fault appears when the output
current rises above approximately 90 A.
The fault clears when output current falls below 5 A for
three seconds.

The solar charge controller monitors its internal
temperatures to protect components from high
temperature damage. If the internal temperatures rise
above 203 °F (95 °C) while operating in Charge mode,
the solar charge controller registers a fault and stops
producing power. The fault clears when the internal
temperature falls to 185 °F (85 °C) for at least 10 seconds.

Battery Over Temp Fault appears when the battery
temperature reaches 140 °F (60 °C). The fault clears
when the battery temperature falls to 131 °F (55 °C).

Battery Setup Conflict Fault appears when you have
configured:
• more than one charging device on the same battery
bank with an inconsistent nominal battery voltage
setting
• an inconsistent battery type setting.
