System Configuration

“serviceable” item that may be removed from the system. In residential
systems, it is located at the utility panel, after the power has gone through
the kilowatt-hour meter of the utility (if present).
Bonding at the AC
Panel Renewable energy systems, with no grid connection, can be grounded at
the main AC distribution panel. Renewable energy systems should be
grounded to the same grounding electrode as the AC distribution panel.
Bond at one point
only Bonding must be done at only one point in an electrical system.
Inherently, Xantrex systems have two separate electric systems; a DC
system and an AC system. This means that two bonding points will occur
in all inverter applications. The bonding point will also be connected to
the equipment (chassis) grounding conductors. It is common to have two
separate conductors connect the ground electrode and the two bonding
points. Each conductor should use a separate clamp.
Battery Considerations
Important: The ground and neutral must be bonded at one place, and
only one place, in the system.
If the generator is the main source of power, (i.e., no utility grid power)
then the neutral and ground connections are bonded at the main AC
distribution panel.
If the utility grid is the main source of power, then the bond should be at
the utility AC distribution panel.
If there is no utility or generator in the system, then the ground/neutral
bond should be in the inverter AC distribution panel.
WARNING: Shock Hazard
The Sine Wave Plus is intended to operate with batteries as its
source of DC power. DO NOT connect DC charging sources
such as PV, wind turbines, or micro-hydro turbines directly to
the
Sine Wave Plus .
Dangerous conditions which can be harmful to personnel and
equipment can exist when DC charging sources are connected
directly to the inverter, these conditions include: unexpected
AC power output from inverter/charger and damage to inverter/
charger from unregulated high DC voltage input.
