Product Manual

Introduction
1–4 975-0240-01-01
The Conext XW+ has an internal automatic transfer switch (K1, K2) which allows
either AC1 or AC2 to be connected to the inverter input, but not both at the same
time (See Figure 1-1, “Connection Points and Major Power Conversion
Components of Conext XW+ ” on page 1–4). This allows shared AC energy
during charging or to directly pass through from AC1, or AC2, to AC Out.
Through firmware control over power conversion and the management of K1 and
K2, Conext XW+ can facilitate advanced interaction with the utility grid to
optimize the utilization of renewable and non-renewable energy sources.
Because the Conext XW+ is a device capable of forming an AC grid signal (AC
voltage and frequency) it is also ideal for use off-grid.
The red arrows in the diagrams below represent the direction of power flow in the
respective modes of operation. These modes and other special functions will be
explained throughout this manual.
