Battery Tips
Explosive/Corrosive Gases Lead-acid batteries may emit
hydrogen, oxygen, and sulfuric 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.
Temperature Sensitivity The capacity of lead-acid batteries
is temperature sensitive. Battery capacity is rated at 77º F
(25º C). At 0º F (–20º C), the Ah capacity is about half the
rated capacity. Temperature should be considered when you
design 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
temperature results in short battery life and should be avoided
by ventilating the enclosure and reducing the external heat
source by shading and insulation.
