During operation, the solar charge controller continuously
monitors the input voltage. If the voltage exceeds
137 VDC (± 1 V) for one second, the solar charge
controller displays an Input Over Voltage Warning. The
warning clears itself when the voltage falls to 134 VDC for
1 second.


During operation, the solar charge controller continuously
monitors the input voltage. If the voltage exceeds
142 VDC (± 1 V), the solar charge controller instantly
registers an Input Over Voltage Fault. The detection
circuitry is faster than breakers or fuses, and they will not
trip or blow when a fault occurs. The fault clears itself
when the voltage falls to 140 VDC for 5 seconds.

Battery Over Voltage Fault appears when the battery
voltage becomes abnormally high and the solar charge
controller stops charging to protect the batteries. The
fault occurs when battery voltage rises above the nominal
voltage plus:
• 4.5 V per 12 V (for example, above 33 V in a 24 V
system) for 1 second.
• 5.5 V per 12 V for 20 milliseconds.
The fault clears when battery voltage falls to the nominal
voltage plus 3.5 V per 12 V for 10 seconds.
