2.3 Unpacking and Handling

• Never lift batteries by the terminal posts, use carry handles.

• Do not short circuit.

• Check for damage. All batteries with visible defects should be reported.

• It is recommended to check the OCV (Open Circuit Voltage) on arrival

3. Installation and Commissioning

3.1 Tools

• Insulated tools

• Voltmeter

• Post cleaner and wire brush

• Personal protective equipment

3.2 Battery Location

• Locate the batteries close to the inverter in order to minimize the length of the battery cables.

• Battery performance and service life will be optimized when they are operated in an ambient temperature of 15°C to 25°C

(59°F to 77°F).

• All electrical protective measures, devices, accommodation and ventilation of the battery installation area must be in

accordance with all local rules and governmental regulations.

• The battery should be installed in a clean and dry area and protected against dropped items and dirt.

• Avoid placing the battery in a hot place or in direct sunlight.

• Avoid conditions that result in spot heating or cooling, as temperature variations will cause electrical imbalances in the

battery. For better cooling and temperature management the batteries should have a minimum of 0.50" (12.7mm) of space

to ensure adequate air flow around each battery.

• The layout of the battery room or installation area must allow for easy access to the batteries.

• Be sure to provide adequate space and lighting for inspection, maintenance, testing, and battery replacement. Space

should also be provided to allow the operation of lifting equipment and for taking measurements (battery voltage and

temperature) during service.

3.3 Racks and Mechanical Stability

• Approved and insulated battery racks are recommended for proper installation. Calculations should be performed to

ensure that floor loading capabilities are not exceeded. Seismic forces should also be considered.

• The installation should provide for adequate structural support and exposure to the minimum possible vibration.

3.4 Parallel Connections

Discover

Solar Dry Cell may be connected in parallel to increase capacity, current capability and/or

discharge durations. In the case of each parallel connected string, only use batteries of the same voltage,

capacity, design and age.

The resistance and ampacity of the cables or connector bars in each string must be the same, e.g. same

cross-section, same length and same conductor type (copper, aluminum). In addition, each string should

be equipped with disconnect capabilities (circuit breakers) for maintenance and safety purposes.

Discover

recommends a maximum of 3 strings parallel: The following steps should be fulfilled to have

battery string in parallel without reducing battery life or batteries getting out of balance:

• Same voltage drop must be realized from each string to the end connection (load and ground). This can be

achieved by proper choice of cable lengths, cable diameters and arrangement for crosswise connection configurations.

• Same length connector cables for positive and negative terminals for each string.
