WARNING

Review “Precautions When Working With Batteries” on page viii before you work with the batteries in your system.

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. 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.

Discharged Batteries Do not leave batteries in a discharged state for more than a day or two. They will undergo a chemical process (sulfation) that can permanently damage the battery. As well, batteries self-discharge over a period of three to six months, so they should be recharged periodically even if they are not being used.

Electrolyte Level If your batteries are not the “maintenance-free” type, check the electrolyte level at least once a month. Excessive fluid loss is a sign of overcharging. Replenish the electrolyte using distilled water only.
