qualified by all. If the system was in passthrough and AC fails on any unit, all units
transfer to invert simultaneously.
Faults
When the Conext XW Pro detects a fault condition, the fault is displayed on the Conext
XW Pro. The Conext XW Pro also turns on the Event LED on the Conext XW Pro and
inverter information panel. A fault affects the operation of the unit. See "Fault Types" on
page113 for an explanation of the different fault types.
When a single Conext XW Pro slave unit in a multi-unit system has a fault, only the
affected device shuts down.
When a master unit has an invert mode fault that causes it to stop inverting, it is
considered a system-wide fault and all units shut down. Invert mode faults on slave units
only shut down the affected slave unit.
All units shut down when there is a battery-related fault such as battery over-temperature
or over-voltage.
Independent Operation of Features
Each Conext XW Pro grid-interactive feature (e.g. enhanced grid support, grid sell, load
shave and generator support) operates independently. This enables Conext XW Pro units
in a multi-unit system to be configured to perform multiple functions independently and
allows greater flexibility in operating the entire system.
Auxiliary Output
Each Conext XW Pro has one programmable 12 V, 0.25 A auxiliary output that is able to
run a small fan or operate an external relay to perform other functions. Examples include
remotely starting a two-wire start generator in cases where the Xanbus-enabled Conext
XW Pro AGS is not used, disconnecting external non-critical loads, or turning on a
diversion load for battery voltage regulation. See "Auxiliary Output Settings" on page80
for programing parameters.
Transfer Relays
The built-in transfer relays, designated K1 and K2, are each is rated for 60 amps.
Connected loads must not draw currents exceeding this.When an external AC source is
detected and qualified on either of the AC1 or AC2 inputs, the relay transfers loads from
the Conext XW Pro to the external power source, and then activates the battery charger.
The Conext XW Pro design does not allow the K1 and K2 relays to close simultaneously.
This design helps stop the generator input (AC2) from back feeding to the utility grid
(AC1). Multi-unit systems of three or more require the use of an external AC contactor to
manage the AC bus.
