Battery tips
Temperature sensitivity The capacity of lead-acid batteries
is temperature sensitive. Battery capacity is rated at 77 ºF
(25 ºC). At 0º F (–20 ºC), the Ah capacity is about half the
rated capacity. You should consider temperature when
designing your system.
Low temperatures If extremely low temperatures are
expected where the inverter is going to be located, you should
consider a heated equipment room. If the system is located in
an unheated space, an insulated battery enclosure is
recommended.
High temperatures The batteries should also be protected
from high temperatures. These can be caused by high
ambient temperatures, solar heating of the battery enclosure,
or heat released by a nearby engine or generator. High battery
temperatures shorten battery life and therefore you should
ventilate the enclosure and use shade and insulation as
appropriate.
Note: Review “Precautions when working with batteries” on
page vii, before working with the batteries in your system.
WARNING: Explosive/corrosive gases
Lead-acid batteries may emit hydrogen, oxygen, and
sulphuric acid fumes when recharging. To reduce the risk
of explosion:
• Vent the battery compartment to prevent the
accumulation of gases.
• Do not install electronic or electrical equipment in the
battery compartment.
• Do not smoke or use an open flame when working
around batteries.
