Threshold = 2% of

When the charge cycle is interrupted, the charger will restart charging at the beginning of
the multi-stage algorithm.
Exit Current Threshold can be effectively disabled by programming the amp-hour
capacity to 0. In this case, absorption will only exit once the Absorption Time timer
expires.
Charge current during equalize state (optional state not shown in graph) is normally
limited to 10% of the programmed amp-hour capacity setting. If this setting is
programmed to 0 Ah, the charge current during equalize is limited to whatever is
programmed for the max current limit of the unit (the default current limit in equalize mode
is 60 A).
Synchronized charge states are active when more than one charging device (Conext XW
Pro or Conext MPPT solar charge controller is connected in the system via the Xanbus
network.
The first unit (Conext XW Pro or Conext MPPT solar charge controller to enter bulk,
causes the other chargers to enter bulk.
The first Conext XW Pro to enter absorption causes the others to enter absorption.
The last Conext XW Pro ready to exit absorption triggers the others to exit absorption and
exit charge. The Conext XW Pro will not wait for any connected Conext MPPT solar
charge controllers to transition to absorption or float.
