Receiving, Moving, and Storing Systems and Batteries

102.1 Shipping Damage
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 the carrier immediately of leaking or damaged cartons for possible concealed damage.
102.2 Temporary Storage of Units and Batteries
For temporary storage of 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° to +40° C (32° to +104° F). Batteries will have a longer shelf life if stored at 15° C (60° F). The Micro-Inverter electronics and battery cabinets may be stored at -20° to +60° C (-4° to +140° F).
IMPORTANT:
Lengthy storage of batteries will cause irreversible damage to the cells. Failure to connect 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 the 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

103.1 Operating Environment
Install the 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:
Micro inverter Systems with Lead Calcium batteries are UL Listed for 20° to 30° C (+ 68° to +86° F) operation. Micro inverter Systems with Nickel Cadmium batteries are UL Listed for 0° to 50° C (+ 32° to +122° F) operation. Battery performance and the 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 a normal temperature of 25° C (77° F). At 45° C (113° F), battery life will be one-fourth of normal.
Temperature Effect On Nickel Cadmium Battery Performance :
Nickel Cadmium 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 technician must observe important safety precautions while performing the following recommended tasks:

• Inspect and clean the unit interiors;
• Inspect all batteries for leaks, cause swelling or terminal corrosion;
• Perform an emergency operation test to check the operation of all critical connected loads

200.3 Manual Routine Inverter Tests
NFPA101 requires that Emergency Lighting Equipment be tested on a monthly basis for a period of at least 5 seconds, and a minimum of 90 minutes once a year. We strongly recommend these guidelines be followed to ensure system readiness and to prolong battery life. The Micro-Inverter system was designed with a front panel test switch to facilitate monthly testing. Simply depress the button and hold to test the inverter at any time. Once released, the Micro Inverter will revert back to standby operation. For annual 90-minute discharge or other prolonged tests, simply turn off the AC Input breaker at the service panel.
200.4 Routine Battery Inspection and Maintenance
Sealed Lead-Calcium Batteries
Maintenance-free cells are the most common type of battery used today in standby equipment. By design, it is as maintenance-free as a battery can be. It is recommended, however, that some simple steps be taken to increase system life and maximize reliability:

A) A quarterly visual check of the battery should be conducted to look for deformities in the battery case, electrolyte leakage, and/or terminal corrosion. Any batteries with these conditions are defective and should be replaced. Any corroded terminals found, regardless of how slight, are to be cleaned at once to prevent system failure.
B) Once a year, all battery connections should be checked for tightness and cleaned and retightened as necessary.
200.5 Battery Replacement Procedure
WARNING: Always use the same quantity and type of battery as replacements. Substituting batteries not supplied by the manufacturer will void the UL listing of the system and may cause equipment failure.
