Battery Management System Functionality
The Lithium Iron Phosphate cells are monitored and protected by an internal battery Management
System (BMS) which provides a multitude of protection features such as:
•Over- and Under-voltage protection
•Charge and discharge over-current protection
•Short-circuit protection
•Over- and Under-temperature
In the case of any of the aforementioned protection, the BMS will disable charge or charging
capability or shutdown the battery entirely to prevent damaging of the cells.
The BMS will shut the battery down and enter a low power consumption mode if any of the following
conditions are met:
•Cell or total pack under-voltage protections has not been released after 30s
•The minimum cell voltage is under the Sleep cell voltage and the duration exceeds the sleep
delay while there is no communication, protection, cell balancing or battery current present.
•The battery is in Standby mode for more than 24 hours while there is no communication,
protection, cell balancing or battery current present.
•Forced shutdown by pressing the RESET button for 3-6 seconds and then releasing.
Note: If the BMS enters low-power mode and shuts the battery down due to cell or total under
voltage, the BMS will intermittently attempt to charge the battery every 4 hours for a total of 10
times, after which it will no longer automatically attempt to charge.
In order restart the battery and the cause the BMS to exit the low power sleep mode, any of the
following conditions need to be met:
•Applying an external voltage greater than 48V but lower or equal to the Charge Voltage to
the battery terminals.
•Pressing the RESET button for 3-6 seconds and then releasing.

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 48Vdc.
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 48-54V 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 >48V 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 5.4 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 32V.
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 48V, 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 charging
current between 10A to 20A.

Precautions
Storage
1. 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
2. Do not store the battery in direct sunlight.
3. The battery should be charged and discharged every 6 months.
4. 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. Make sure the breaker of the battery is in the OFF position.
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. The batteries cannot be used in series as the BMS is designed for a 48V battery system.
9. The battery/batteries need to be connected to earth and the earth resistance needs to be
less than 1.
10. Verify that the inverter parameters match that of the battery.
11. The battery should be kept away from heat, fire and water.
12. Verify all connections before switching the breaker 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. It is also recommended to switch the BMS OFF by press and holding the
RESET switch down for a few seconds.
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.
