Suitability
This automatic neutral-to-ground bonding
system requires AC input sources with bonded neutral. This
will be the case in most situations: in a utility feed, at an
external AC hook-up, or a generator with a bonded neutral. If
not, have an electrician look into bonding the source’s neutral
to ground. See also “AC Input and Output Isolation” on page
28.
DC Components
Batteries
The
$XWR3RZHU
system requires a 12
Y
lead-acid deep-cycle
battery or group of batteries to provide the DC current that
the inverter/charger converts to AC power. The battery may
be a flooded, gel, or AGM type.

DC Cabling
Definition
DC cabling includes all of the cables and
connectors between the batteries, the DC disconnect and
overcurrent protection device, and the inverter/charger.
Type
All installations require multi-strand insulated cables.
The DC cables must be copper and must be rated 75°C
minimum.
