Generator
If the generator is the main source of power, (that is, no
utility grid power) then the neutral and ground connections are bonded at
the main AC distribution panel.
Utility grid
If the utility grid is the main source of power, then the bond
should be at the utility AC distribution panel.
No utility or generator
If there is no utility or generator in the system,
then the ground/neutral bond should be in the inverter AC distribution
panel.
Battery Considerations
Accessibility
Locate the batteries in an accessible location if maintenance is required.
Two feet clearance above the batteries is recommended for access to the
battery caps. They should be located as close to the inverter as possible
without limiting access to the inverter’s disconnects. Install the batteries
to the right of a wall-mounted inverter for easy access to the DC side of
the inverter and shorter cable runs. The battery bank may also be placed
on the opposite side of the wall on which the inverter is mounted.
Vented enclosures
For safety and to limit access to the batteries, the batteries should be
housed in an enclosure or dedicated room that can be locked or screened,
and ventilated. It should be vented to the outside by a 1-inch minimum
vent pipe located at the top of the enclosure. An intake vent should be
installed at the bottom of the enclosure to promote air circulation.
Enclosure
requirements
The enclosure should be made of an acid resistant material or have a
finish that resists acid to prevent corrosion and must be capable of
containing the electrolyte from at least one battery should a leak occur.
Enclosures located outside must be rainproof and screened to prevent
access by rodents or insects and insulated from extreme temperatures.
Batteries will give their best performance and service life when operating
in a 20 to 25 °C (68 to 77° F) environment.
CAUTION: Damage to Equipment
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 arrays, wind turbines, or
micro-hydro turbines, directly to the
Sine Wave Plus
. If DC charging sources are
connected directly to the inverter, the DC rating of the inverter can be exceeded
and the inverter can be damaged.
Important:
These vents exhaust corrosive and explosive hydrogen sulfide
gases and must not be overlooked when designing an enclosure.
