Eastman 5kWh Lithium Battery Technical Specifications

Key Features Explained

Advanced LiFePO4 Technology

The Eastman ES51.2 series employs high-performance lithium iron phosphate batteries as the fundamental energy storage unit. LiFePO4 chemistry offers superior safety characteristics and longer service life compared to traditional lead-acid or other lithium chemistries .

Intelligent Thermal Management

Through scientific and reasonable active heat dissipation, the system improves internal temperature field consistency. This extends battery service life and enables continuous high-current output when your home demands more power .

Comprehensive Monitoring

The external color touch screen provides real-time visibility into battery performance. Six LED indicators show approximate state of charge (SOC), with each LED representing about 17% capacity. For detailed monitoring, the communication ports allow connection to computers or inverters .

Flexible Communication

• RS485/CAN Interface: Connects directly to inverters, allowing the inverter to monitor battery voltage, current, temperature, SOC, SOH, and status .

• RS232 Interface: Enables single-pack monitoring via computer .

• RS485/RS485 Daisy Chain: Used when paralleling multiple batteries—the master pack communicates with slave packs, and all information is accessible through the master’s RS485/CAN port .

Scalable Power

Starting from 5.0kWh, the system can be expanded by adding up to 15 parallel modules. This modular approach lets you start with the capacity you need today and grow as your energy requirements increase .

Applications

• Household Energy Storage: Store solar power for nighttime use, reducing grid dependence and electricity bills .

• RV and Caravan Power: Reliable, maintenance-free power for mobile living .

• Temporary Buildings: Power for construction sites, events, or emergency shelters .

• Backup Power: Keep essential loads running during grid outages .

• Off-Grid Homes: Complete energy independence with solar + storage .

Installation Guidelines

1. Location: Install in a clean, dry, well-ventilated area away from direct sunlight and extreme temperatures.

2. Mobility: The unit comes equipped with wheels, allowing flexible positioning and easy relocation as needed .

3. Connections: Use appropriate M8 terminals for secure power connections—both positive and negative terminals are provided in duplicate .

4. Communication Wiring: Connect RS485/CAN to your inverter for integrated system monitoring and optimized charging.

5. Parallel Configuration: For multiple units, set unique hardware addresses using DIP switches to distinguish each pack in the battery stack .

6. Activation/Sleep: Use the reset button (press 3-6 seconds) to wake the pack from sleep or return it to sleep mode when not in use .

Operation Guide

Power ON/OFF

• To Activate (from sleep): Press and hold the reset button for 3-6 seconds, then release .

• To Sleep (when active): Press and hold the reset button for 3-6 seconds, then release .

Understanding LED Indicators

Six SOC LEDs show approximate charge level, with each representing about 17% of full capacity. As the battery discharges, LEDs turn off progressively from top to bottom .

Communication Port Functions

Dry Contacts

• AM1: Normally open, closes during fault protection conditions

• AM2: Normally open, closes during low energy alarm

Maintenance

• Visual Inspection: Periodically check terminals for tightness and casing for damage.

• Clean Surface: Keep battery top clean and dry.

• Software Monitoring: Use communication ports to periodically check cell balance and system health.

• Firmware: Check with Eastman for any available firmware updates to ensure optimal performance.

Safety Features

The Eastman ES51.2 series incorporates multiple protection layers:

• Overcharge protection

• Deep discharge protection

• Short circuit protection

• Thermal protection

• Weak current switch for safe transport and storage
