voltage. The battery is reconnected when AC power is restored or after
recharging to a preset threshold.
Disconnect Voltage:
Set the threshold to a level that will protect the
battery from excessive discharge (as recommended by the battery
manufacturer). The LVD contactor will open when the battery discharges
to this level for at least 3 seconds. The default setting varies based on
the power modules installed.

Reconnect Voltage:
Set the level where the unit will reconnect to the
battery after it has recharged (as recommended by the battery
manufacturer). The "Reconnect Voltage" must be higher than the
Disconnect Voltage to prevent the LVD contactor repeatedly cycling on
and off. The default setting varies based on the power modules installed.

This setting will be used when charging the battery from an external DC
source (such as a solar system), otherwise once AC power returns the
LVD contactor will automatically close so that the power modules can
charge the battery directly.
NOTE: Deeply discharged batteries will not be reconnected as a safety
measure. R
