Disconnecting the Charge Controller
Before disconnecting batteries and the PV array from the unit, ensure the solar
charge controller is not charging the batteries. If the solar charge controller is
charging, you can wait until the charge cycle is complete or the solar charge
controller displays “Low Light,” or you can put the unit into standby mode.
Standby mode shuts off the solar charge controller output. The solar charge
controller can be put into standby mode using the solar charge controller Device
Menu or the MPPT Setup Menu on the Conext System Control Panel (SCP).
If the solar charge controller is charging when the batteries are disconnected
with a DC disconnect switch, an over-voltage output fault occurs due to the load
on the solar charge controller output being removed. After approximately 10
seconds the solar charge controller LCD goes blank and the solar charge
controller loses power.
Normal operation resumes when the battery is reconnected.
If the unit is not charging, the charge controller simply shuts down when the
batteries are disconnected. No faults are generated.
WARNING
ELECTRICAL SHOCK HAZARD
Ensure that the positive and negative PV conductors and the battery
conductors are disconnected from the solar charge controller before servicing
the solar charge controller or the batteries. After disconnecting the batteries,
the solar charge controller can appear de-energized when the PV array is still
connected.
After disconnecting power from the solar charge controller, wait at least four
minutes before attempting any maintenance or cleaning or working on any
circuits connected to the unit. Internal capacitors remain charged for four
minutes after disconnecting all sources of power.
Failure to follow these instructions can result in death or serious injury.
