High Battery Transfer (HBX)
In High Battery Transfer (HBX) mode, the system is connected to an AC source such as the utility grid;
however, it will use battery power as the first priority. The AC source is locked out until needed.
In this mode, the system runs on battery-supplied power for as long as the batteries can be sustained. It is
expected that the batteries will also be charged from renewable sources such as PV power. When the
batteries become depleted, the system reconnects to the AC source to operate the loads.
The batteries may be recharged during this time using the renewable source. When the batteries are
recharged to a high enough voltage, the system transfers back to the batteries as the primary source
(hence the name High Battery Transfer).
Note:
For best operation, the inverter’s charger should be turned off when HBX mode is in use. HBX
mode is intended for systems that rely primarily on the renewable energy source for charging. The
settings of HBX mode allow it to disconnect from the utility grid whenever it can charge effectively using
the renewable source. Use of the inverter's charger may interfere with these priorities. This may keep
both HBX mode and the inverter's charger from working effectively.
See page 48 (the
CHARGER
hot key) for instructions on shutting off the charger function.
HBX Mode commands the inverter to:
connect to an AC source if the battery voltage has fallen below the
Grid Connect
voltage for the
amount of time set in the (connect)
Delay
set point,
connect to an AC source if the battery state of charge (SOC) has fallen below the
Grid Connect SOC
for
any amount of time,
disconnect the AC source and switch to powering the loads from the battery bank if the battery
voltage has risen above the
Grid Disconnect
voltage for the amount of time set in the (disconnect)
Delay
set point, and
disconnect the AC source and switch to powering loads from the battery bank if the battery state of
charge (SOC) has risen abovethe
Grid Disconnect SOC
for any amount of time.
The
Delay
set points are used to prevent the inverter from switching to grid power in the event of a
sudden, sizable demand for power that may momentarily drop the voltage below the
Grid Connect
value.
The
SOC
set points are only usable by a system equipped with a battery monitor.

Note: The system must be in the
Grid Disconnect
state to allow HBX default settings to be changed.
IMPORTANT:
HBX Mode will control the master inverter in port 1 of a HUB-4 or HUB-10. The master
will then instruct any stacked slaves to connect or disconnect from the AC input source.
IMPORTANT:
HBX Mode should not be used if
GRID USE TIME
is used (see page 129). These
functions have incompatible priorities and will conflict with each other.
