2. Relative humidity < 85%.

3. Minimal dust.

4. Ambient temperature between 0-40°C, ideally ~25°C.

a. Frequent exposure to high temperatures will shorten the life of the battery.

5. No flammable or explosive materials may be near the batteries.

Installation Procedure

Note that the battery terminals are live by default and care should be taken when handling them.

The

1. Install the battery in the desired location, preferably inside a cabinet.

a. Please make sure the cabinet can support the weight of the battery / batteries.

2. Connect the power cables between the batteries (when using multiple batteries refer to

section 5.4)

a. Red and black cables as depicted in Figure 5.

b. Please ensure the power cables are properly torqued to minimum 10N.m for the M8

terminal.

3. Connect the cables to the inverter via the DC fuse and breaker.

a. Please ensure the polarity of the connection between the inverter and the batteries

are correct.

4. Once the above has been done, please verify all the connections to ensure everything is

as specified.

5. Follow the instructions as specified in the installer manual before switching the inverter ON.

a. The inverter should automatically detect the battery and start-up.

6. Configure the inverter settings as follows:

a. Charge Voltage : 28.0 V

b. Float Voltage : 27.2 V

c. Charge Current : 30 A (per battery connected)

d. Equalization: Disabled

Parallel connection

The AZBAT24100A battery can be used in parallel with batteries of the same model, capacity, and

manufacturer.

1. DO NOT connect different batteries in parallel.

2. A maximum of 4 batteries connected in parallel is allowed.

3. When using more than one battery, ensure that all battery voltages are fairly similar or within

0.2V of each other.

a. A large voltage difference will cause an over-current event due to the inrush current

flowing from one battery to the other.

4. Ensure that the batteries are wired in a diagonal fashion, as shown in Figure 3, with the

positive connection from the inverter first connected to the first battery and the negative

connection from the inverter connected first to the last battery

Figure 3: Parallel Battery Diagonal Wiring

Series connection

The AZBAT24100A battery can be used in series with batteries of the same model, capacity and

manufacturer.

1. Ensure that both batteries are fully charged and all cells are balanced before connecting

them in series.

2. DO NOT connect batteries in series without a battery balancer module.

a. This is due to the protection nature of the BMS used in Li-ion batteries.

b. If a single battery reaches full charge it will prevent the other battery that it is

connected to, in series, from continuing to charge.

c. If a single battery reaches full discharge it will prevent the other battery that it is

connected to, in series, from discharging further.

Troubleshooting

Battery start-up procedure

In some cases the battery will go into a safe mode in the event of a short circuit or over-discharge.

The Short Circuit Protection (SCP) circuit in the battery can potentially be activated when connected

to an inverter or parallel battery for the first time. Since some inverters have large input capacitors,

there is a significant inrush current from the battery to the capacitors inside the inverter which

activates the SCP on the battery.

The BMS inside the battery switches off output voltage resulting in an open-circuit. This is visually

evident when the display on the battery does not switch on. This can be confirmed by connecting a

multi-meter on the terminals of the battery and measuring the voltage which should always be larger

than 24Vdc.

In the case of a shut-down the battery needs to be manually reset by following the procedure below:

1. Connect AC power to the inverter after following the procedures as recommended in the

inverter installation manual. With some inverters models the battery will automatically reset

once power is applied to the inverter.

2. If the battery did not switch ON, disconnect the AC power to the inverter.

3. Use an isolated power supply or a battery charger with an output voltage of 24-29V and a

current output larger 1A but less than 10A.

4. Apply the voltage to the terminals of the battery for a few seconds until the voltage on the

battery is >24V after which the external voltage source can be removed.

5. The input capacitors on the inverter will remain charged while the battery is connected to the

inverter

Battery pack voltage is low or zero

1. If the battery is fully charged it will open-circuit to prevent overcharging.

a. Applying a load will reset the protection feature.

2. If the battery has been in storage for a long period or over-discharged it will open-circuit to

prevent further discharging.

a. Follow the battery start-up procedure in Section 7.1 to re-energize the battery.

3. Unstable battery voltage or irregular charging.

a. Make sure that there is proper connections on the battery terminals.

4. Battery voltage between 0V and 16V.

a. The battery has been over-discharged and may have lost some capacity. Apply a

charging voltage with a maximum of 10A charging current to re-energize the battery

cells.

b. If the battery voltage reaches 24V, increase the charging current and continue to

charge to full capacity.

c. Otherwise, immediately stop charging the battery as it has failed and will no longer

hold charge. Continuing to charge such a battery will result in over-heating and

eventually cause a fire or cell combustion.

Insufficient Energy Capacity

Cycle the battery 4 – 5 times by discharging to 80% DoD and then charging with a low

charging current between 2A to 10A.

Precautions

Storage

6. If the battery is stored for more than 3 months, it should be stored under environmentally

controlled conditions:

a. Ambient temperature: 25 ±3°C

b. Humidity: 25-85% RH

c. Air pressure: 86kPa-106kPa

7. Do not store the battery in direct sunlight.

8. The battery should be charged and discharged every 6 months.

9. Battery storage SOC should be >50%

Safety

Before use

1. Inspect the battery to ensure that it is not damaged. If damaged, please inform the supplier.

2. Ensure that the installation is done by a qualified installer.

3. The installation needs to be done in compliance with the specified regulatory standards as

required by governmental and local authorities.

4. Keep in mind that the battery terminals are live.

5. Ensure that the inverter is not powered from AC mains while connecting the battery.

6. It is advised to use suitable protection between the battery and the inverter.

7. Make sure the polarity (positive and negative) connections between the batteries (parallel

use) and between the master/main battery and the inverter is correct.

8. Verify that the inverter parameters match that of the battery.

9. The battery should be kept away from heat, fire and water.

10. Double check all connections before switching the breaker/isolator switch to the ON position.

During use

1. In the event of altering or moving the installation, make sure that the breaker switch is in the

OFF position and the inverter is switched OFF.

2. Do not use this battery with that of another supplier or a different type of battery.

3. Do not use the batteries with a faulty or incompatible inverter.

4. Do not exceed the charging current and discharging current parameters of the battery.

5. Overcharging or over-discharging will shorten the life-span of the battery and may cause the

battery pack fail or overheat and catch fire.
