Overview
The AZBAT24100C incorporates 8x3.2V 100Ah (8S1P configuration) Lithium-Iron Phosphate
(LiFePO4) cells with a recommended 0.3C charge and 0.5C discharge current rating. The battery
incorporates a battery management system (BMS) which provides the following functionality:
•Protection
oCell overcharge and discharge
oShort circuit
oOver and under temperature
oTotal over- and under-voltage
•Control
oCell balancing
The BMS has been tested with leading inverters, including Synapse, Voltronic and GroWatt and has
been UN38.3 and IEC 62619 certified.
The battery is mounted in a durable steel casing with spring loaded handles for easy handling. It
features a LCD display* with an display on/off button. The battery is fitted with M8 terminal
connections for sturdy connection to the battery cables.
*The SoC displayed on the LCD is only an estimation which is based on the battery pack voltage.
This will be most accurate when the battery is in steady-state no-load.

Installation Location
Please note the requirements for the installation location:
1. The area needs to be dry.
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 : 29.2 Vmax
b. Float Voltage : 27.2 V
c. Charge Current : 30 A (per battery connected)
d. Equalization: Disabled
Parallel connection
The AZBAT24100C 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 AZBAT24100C 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.
1. 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,

Revision 1.02

PowerSense®Series
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.
