Receiving, Moving, and Storing Systems and Batteries
Shipping Damage
Tucson Micro inverter system batteries are shipped along with the unit within a single shipping carton. Batteries for most
units are not shipped within the housing with the exception of Plenum Rated Ceiling Mount (T-Grid) models.
Carefully inspect all cartons upon receipt for evidence of shipping damage.
Notify carrier immediately of leaking or damaged cartons for possible concealed damage.
Temporary Storage of Units and Batteries
For temporary storage of Tucson Micro inverter systems and batteries prior to installation, select a clean, cool, dry location
with normal ventilation for human habitation and level floors.
Storage Temperature:
Store all batteries at 0°C to 40°C (32°F to 104°F). Batteries will have a longer shelf life if stored at 15°C (60°F). The
Tucson Micro electronics and battery cabinets may be stored at -20°C to 60°C (-4°F to 140°F).
IMPORTANT:
Lengthy storage of batteries will cause irreversible damage to the cells. Failure to connect Tucson Micro
inverter system batteries to an energized charging circuit within 90 days from the date of shipment will void the battery
warranty.
DANGER:
Explosive - Can Cause Blindness or Other Severe Injuries
Every type of battery can produce hydrogen gas, even sealed, maintenance-free batteries. The gas is vented through the
vent caps and into the air. Do not allow smoking, sparks, or flames in battery storage location because hydrogen is
concentrated under the vent cap of each cell of the battery. Hydrogen is highly explosive, and is hard to detect because it
is colorless, odorless, and lighter than air.
Installation Requirements
Operating Environment
Install the Tucson Micro inverter system in a clean, cool, dry place with normal ventilation for human habitation and in
such a location to hamper vandalism but allow easy access for testing and maintenance.
Operating Temperature:
Tucson Micro inverter systems with sealed lead calcium batteries are UL Listed for 20°C to 30°C (68°F to 86°F) operation.
Tucson Micro inverter systems with NiCad batteries are UL Listed for 0°C to 50°C (32°F to 122°F) operation.
Battery performance and service life is maximized if the operating temperature is maintained at 25°C (77°F).
Temperature Effect on Lead Calcium Battery Performance:
Lead Calcium batteries will be less efficient at temperatures below 20°C (68°F), and high temperatures will reduce battery
life. Typically, at 35°C (95°F), battery life will be half of what it would be at normal temperature of 25°C (77°F). At 45°C
(113°F), battery life will be one-fourth of normal.
Temperature Effect on NiCad Battery Performance:
NiCad batteries will provide their full rated capacity throughout their useful life when operated within a range of 0°C to
50°C (32°F to 122°F).
Ventilation:
The air around the unit must be clean, dust-free, and free of corrosive chemicals or other contaminants. Do not place the
Tucson Micro inverter system or batteries in a sealed room or container.
CAUTION:
Never install batteries in a sealed room or enclosure.
High Altitude Operation:
The maximum operating temperature drops 1°C per 300 meters (2°F per 1000 feet) above sea level.
Maximum elevation is 3000 meters (10,000 feet).
