Freedom X Owner's Guide
AC Shore Power
A source of 120 volts AC 60Hz sine wave alternating current
provides energy to pass power through to AC loads. This source
is usually the utility grid (power company) or an AC generator. An
automatic or manual AC source selector switch can be used to
switch between the multiple sources of shore power to the
Freedom X system.
The AC source feeding the Freedom X must have the neutral
conductor bonded to ground. When the inverter passes shore
power through, it will lift its internal bonding relay on the output and
will rely on the input being bonded in order to ensure that the power
delivered to a sub panel is properly bonded. See
for more information on bonding relay operation.
NOTE
: Throughout this guide, the term “shore power” refers to AC
input power from a utility grid, generator, or other AC source.
AC Disconnect and Over-Current
Protection Device
Most safety requirements and electrical codes require the
Freedom X’s AC and DC inputs and outputs to be provided with
over-current protection (such as circuit breakers or fuses) and
disconnect devices.
AC Input
The circuit breaker or fuse (connected through
hard wiring) that is used to supply the Freedom X
must be rated at no more than 30A and must be
approved for use on 120 volts AC branch circuits.
The wire used between the breaker and the
Freedom X input must be sized adequately to
carry current up to the rating of the input breaker
and in accordance with the electrical codes or
regulations applicable to your installation.
AC Output
The circuit breaker or fuse must be rated at no
more than the rating of the input breaker in the
installation and must be approved for use on
120 volts AC branch circuits. The wire used
between the Freedom X and the AC output
breaker must be of adequate size to match the
AC input circuit breaker’s rating. The wiring
from each AC output breaker to each of the
loads must be adequately sized to carry the
current rating of the individual AC output
breaker.
