AC Input Settings
The AC Settings menu configures the voltage and frequency limits for AC port 1
(Grid) and AC port 2 (Gen). These are the limits at which the Conext XW+
considers AC input voltage qualified—that is, suitable for charging batteries or
passing through to loads attached to AC OUT. If the input voltage is not qualified
according to these settings, the Conext XW+ reverts to inverting external DC
energy to AC energy for loads on AC OUT.
WARNING
ADVANCED CONFIGURATION HAZARD
Advanced menu settings should be used by qualified personnel only.
Three phase operation should be configured by qualified personnel only.
Consult with the local utility before enabling Conext XW+ sell mode or grid
support functions.
Do not change these settings unless you are under the supervision and
direction of qualified personnel.
Failure to follow these instructions can result in death or serious injury.
NOTICE
THREE-PHASE CONFIGURATION COMPATIBILITY
The Conext XW+ is configured from the factory as a split-phase inverter. In
order to qualify the input, the AC input to the inverter must be split phase: V
Line1–
Neutral
+ V
Line2–Neutral
= V
Line1–Line2
. The Conext XW+ can be converted and
configured for single-phase operation (120 V only). A split-phase
Conext XW+
cannot accept input from a three-phase source, so the inverter must be
converted to single-phase operation and connected to a 120 V leg.
Failure to follow these instructions can result in equipment damage.

Item Description
AC Priority
Sets the priority for the AC input source (AC1 or AC2) for qualification and
transfer.
In systems that use both utility grid (AC1) and generator (AC2) input, it is
recommended that you set
AC Priority to AC1. Assuming the generator is
intended for occasional use only, the Conext XW+ will use utility power. It will use
the generator only if AC1 is unavailable, and if the generator is running.
