Battery Considerations

Battery Voltage

Battery Location

Battery Temperature

NOTE: Cold temperatures
drastically reduce battery
capacity and performance.
Be sure to locate batteries
in an environment with a
stable temperature.

See Appendix B for more detailed information on battery types, battery-bank
sizing, battery configurations, wiring requirements, and battery care and
maintenance.
These inverters are for use with a 12 Vdc battery system only.
• Locate the batteries in an accessible location. Two feet of 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 to ensure shorter cable runs.
• For safety and to limit access to the batteries, a secure/lockable, ventilated
battery enclosure or dedicated room should be used. If an enclosure is used, it
should be vented to the outside via a one-inch vent pipe located at the top of
the enclosure. Install an intake vent at the bottom of the enclosure to promote
air circulation. These vents exhaust explosive hydrogen gases and must not be
overlooked when designing an enclosure.
• The enclosure should be made of an acid-resistant material or have a finish that
resists acid to prevent corrosion. It should be capable of holding the electrolyte
from at least one cell of one battery should a leak occur.
• Enclosures located outside must be rainproof and screened to prevent access by
rodents or insects.
The battery enclosure should provide a fairly stable temperature for the
batteries. For installation in a cold environment, insulation should be used to
protect the batteries from the cold. Insulation also provides a more consistent
temperature and better system performance.
The battery enclosure should not be installed in direct sunlight or in locations
where the sun can overheat the batteries. Locate the enclosure where it will be
protected from the afternoon sun and provide vents in the top and bottom of the
enclosure to provide air flow. High battery temperatures greatly shorten the life
of the batteries.
