Arc Fault
The Arc Fault Detector is a unique safety component included in every Classic, because safety is not an
option, the engineers at MidNite take
action as the 2011 NEC code requires.
The Classic is the first charge controller in
the world to successfully stop a series arc.
The Classic can detect an arc in less than
100mSec. From low power arcing to
devastating high power arcing, the Classic
will detect and shut down with an audible
and visible alert to announce that there is
a problem in the PV side of the system.
When an arc is detected the Classic has to
be manually cleared.
Resetting the Arc Fault Detector after
detection has occurred: The First thing to
do is find and fix the actual arcing wire,
terminal, splice etc. The Classic needs to
be powered down completely for 15
seconds and then powered back up. Do this by turning the DC source (PV, Wind or hydro etc.) breaker
off. Then turn off the external battery breaker. Than simply turn the 2 breakers back on starting with the
battery breaker.
The arc fault module has three adjustable parameters consisting of: MODE, TIME & SENSITVY
MODE: Is assigned as a 1 from factory default and it should stay that way unless instructed by MidNite
Solar.
TIME: This sets the length of the arc the Classic has to monitor before tripping the Arc fault detection.
This parameter is set to 4 from the factory.
