22A High Xfer (HBX) VDC
This menu is used to set the voltage transfer point when the inverter turns
back on and resumes powering the AC loads from the batteries. When this
setting is reached, the inverter transfers from the AC1 input (grid) to the
batteries to power the loads.
An external DC charging source (wind, solar, etc.) must raise the battery
voltage above this setting before the system resumes inverter operation.
There is no delay in transferring from the grid to the inverter after the
battery voltage reaches this level. This setting is not temperature
compensated.
22B Low Xfer (LBX) VDC
This menu is used to set the voltage transfer point from the batteries to the
AC1 input (grid) due to a low battery condition. The transfer occurs only if
the battery voltage reaches or remains below this setting for 10 seconds.
The system returns to powering the AC loads from the battery once the
battery voltage increases to the level set in menu 22A High Xfer (HBX)
VDC above. This setting is not temperature compensated.
23 ALM Relays Menu
Auxiliary load functions are controlled by setting parameters in Menu
Heading 23 ALM Relays. Using this feature requires the additional
purchase of a Xantrex Auxiliary Load Module (ALM).
The ALM can be used to operate auxiliary loads such as water pumps or
alarms. The two auxiliary relays operate independently of the inverter/
charger status (inverter being ON or OFF). As long as the control circuit is
powered, as evident by the text on the ICM LCD screen being visible, the
AUX relays will operate.
Two voltage-controlled relays (RY9 and RY10) and an AC Output Fault
Relay (RY11) are provided on the optional ALM.
RY9 RY9 (load control relay) is dedicated for use as a load control relay
to prevent battery discharge and is not temperature compensated for the
battery. This relay operates in both the inverter and charger modes.
RY10 RY10 (charge control relay) is dedicated as a control relay for
regulating either a source of DC power or for controlling a load to utilize
excess power from DC sources. This relay is temperature compensated and
uses the 04B Battery Comp VDC display to determine its DC value. This
relay operates in both the inverter and charger modes.
