Introduction
Thank you for your purchase of this Xantrex Home Power System. The
modified sine wave AC output from the inverter ensures AC loads
operating from the unit perform efficiently and correctly.
To get the most out of your PowerHub 1800, carefully read and follow the
instructions in this guide. Pay special attention to the
Important Safety
Instructions
and to the

please contact Xantrex Customer Support. Please see “How do you get
service?” on page WA–1 in this Guide for contact information.
Principles of Inverter Operation
The PowerHub 1800 converts power from the batteries in two stages. The
first stage is a DC-to-DC converter, used to raise the low voltage DC
input to high voltage DC. The second stage is the actual inverter stage,
taking the high voltage DC and converting it to a modified sine wave AC
output.
The DC-to-DC converter stage uses modern high frequency power
conversion technology that eliminates the bulky, low frequency
(50/60 Hz) based transformers found in inverters using older technology.
The inverter stage uses advanced power semiconductors that provide
excellent overload capabilities.
