itel 5.12kWh 51.2V 100Ah Lithium Battery Overview

The itel 5.12kWh 51.2V 100Ah Lithium Battery is a LiFePO₄ battery built for solar energy storage and backup applications. Its 51.2V architecture provides a practical storage platform for compatible low-voltage battery systems.

Because it has a nominal energy capacity of 5.12kWh and an amount of 100Ah, the battery is able to store a sufficient quantity of solar energy for use at times when solar generation is not taking place. The battery can support a maximum continuous charge current of 100A and a maximum continuous discharge current of 100A, the maximum pulse discharge current being 150A.

The battery is also equipped with an intelligent BMS which features over 50 algorithms for ensuring battery safety and for controlling its operation. For communication it provides RS485, CAN and RS232 options, enabling integration with suitable energy-storage equipment.

Key Features and Buyer Benefits

LiFePO₄ Battery Chemistry

The battery uses LiFePO₄ chemistry, making it suitable for solar energy storage applications where regular charging and discharging are required.

Its specified cycle life is more than 6000 cycles at 25°C, 0.5C and 80% DOD, providing a clear indication of its designed cycling capability under the stated test conditions.

Intelligent BMS

More than 50 protection algorithms are offered by the built-in intelligent Battery Management System (BMS). It is an important component of battery operation since it looks after the electrical and safety-related conditions within the battery system.

The capacity is 100Ah and the energy is 5.12kWh.

The battery has a nominal capacity of 100Ah and a nominal energy output of 5.12kWh at a nominal voltage of 51.2V.

When people are comparing a 51.2V 100Ah lithium battery, the three figures in question should be examined together instead of focusing just on the Ah rating.

High Charge and Discharge Capability

The battery can handle a standard charging current of 50A and a maximum continuous charging current of 100A.

The current used for discharge is 100A, the maximum continuous discharge current being 100A and the maximum pulse discharge current 150A.

The inverter and the system settings have to stay within the electrical limits that are specified for the battery.

Parallel Expansion

As many as 15 batteries can be connected in parallel, giving systems that need more total storage capacity an option for expansion.

When carrying out a parallel installation, it is necessary to use equipment that is compatible and to set the communication and system configuration correctly.

Communication Interfaces

The system includes communication ports for RS485, CAN and RS232. Before carrying out the installation, it is necessary to check the communication compatibility with the inverter chosen, including compliance with the required BMS protocol and the connection configuration.

Best For

The 51.2V 100Ah lithium battery is appropriate for:

• Residential solar backup systems
• Hybrid solar energy storage
• Load-shedding backup applications
• Commercial energy storage
• The systems which have a low-voltage battery of 51.2 V
• Solar systems where battery capacity may need to be expanded through parallel connection

Before carrying out the installation, the correct inverter, the battery voltage range, the communication protocol and the current limits should always be checked.

Not Ideal For

One should not choose this battery merely on the grounds that its capacity of 5.12kWh seems suitable; it might be inappropriate in the following cases:

• The inverter requires a different battery voltage architecture
• The inverter does not support the required BMS communication
• The connected load exceeds the battery’s continuous current capability
• The installation environment falls outside the specified operating conditions
• A higher storage capacity is required from a single battery unit

Battery Capacity: kWh, Ah and Backup Time

And kilowatt-hours are different measurements.

The battery has a nominal voltage of 51.2 volts and a capacity of 100 ampere-hours, which gives it a nominal energy rating of 5.12 kilowatt-hours.

The basic energy relationship is:

Voltage × Ah ÷ 1000 = nominal kWh

For this battery:

51.2 × 100 ÷ 1000 = 5.12kWh

The amount of actual usable backup energy will be less than the nominal energy since real systems are influenced by inverter efficiency, the operating limits of the battery, temperature, the condition of the battery, and the load that is connected.

Estimated Backup Time

The figures mentioned are theoretical and are based solely on the nominal energy capacity of 5.12kWh; they do not represent guaranteed running times and do not take into consideration inverter losses or the operating limits of the battery.

When estimating the backup time for a real installation, both the usable energy and the inverter efficiency should be taken into account.

This makes 51 2v 100ah lithium battery backup time dependent on the actual load rather than being a fixed figure.

Battery Management System and Safety

More than fifty protection algorithms are incorporated into the battery’s intelligent BMS.

The battery has a pre-charge function, a current limiting function, LED indications and clearly defined charge and discharge cut-off limits.

The specified operating limits include:

• Charge Voltage Range: 40V–58.4V
• Cut-Off Charging Voltage: 58.4V
• Cut-Off Charging Current: 2A
• Cut-Off Discharge Voltage: 40V
• Cut-Off Discharge Current: 2A
• Current Limiting Function: 10A
• Pre-Charge Function: Enabled
• Display: LED

Charging and Discharging Performance

The battery allows compatible solar storage systems to charge and discharge flexibly.

• Standard Charging Current: 50A
• Maximum Continuous Charging Current: 100A
• Standard Discharging Current: 100A
• Maximum Continuous Discharging Current: 100A
• Maximum Pulse Discharge Current: 150A
• Cut-Off Charging Voltage: 58.4V
• Cut-Off Discharge Voltage: 40V

The charging settings for the inverter should be set in accordance with the electrical limits of the battery.

Inverter Compatibility

Before connecting this battery to a solar inverter, confirm:

• 51.2V battery compatibility
• Compatible charge and discharge current limits
• CAN, RS485 or RS232 communication requirements
• Correct BMS communication protocol
• Battery communication cable and pin configuration
• Maximum number of parallel batteries supported by the complete system

A battery with the right voltage does not always mean the inverter will work with it.

Hajvery Solar will help buyers to check whether batteries and inverters are compatible before they make a purchase.

Parallel Expansion

The itel 51.2V 100Ah battery supports up to 15 batteries in parallel.

The overall energy-storage capacity can be increased by having a parallel expansion when the whole system is designed for use with multiple battery units.

Before expanding the battery bank, the communication setup, the inverter capacity, the protection equipment and the method of installation should be checked.
