Decoding Multi-Dimensional Communication Capabilities of the ECO-WORTHY 48V 100Ah Server Rack Battery

——Supports master-slave interconnection, compatibility with mainstream inverters, and seamless integration with various monitoring systems

I. Product Background and Application Scenarios

In residential and small commercial energy storage systems, communication capabilities determine the level of intelligence of the battery system and the ease of system integration. The 48V (51.2V) 100Ah Server Rack Battery launched by ECO-WORTHY not only has  energy storage capabilities of high-performance but also supports a variety of communication interfaces and protocols. It enables multiple types of data interactions between batteries, between batteries and inverters, and between batteries and various monitoring/remote platforms, greatly enhancing the system's intelligence level and remote maintenance capabilities. 

 

This communication capability allows it to be adapted to a variety of practical scenarios, including parallel expansion, precise control of inverters, and data collection of remote monitoring . It is a key core component in intelligent energy storage systems.

II. Master-Slave Communication Capability Between Batteries

The 48V 100Ah server rack battery from ECO-WORTHY supports parallel use of multiple units, which work together through a master-slave communication mechanism to ensure the safe operation and consistent status of the entire battery group.

In a parallel system, one battery will act as the “master battery”, taking on the task of communicating with external devices (such as inverters or monitoring terminals) and synchronizing relevant control commands to all “slave batteries”. All batteries are interconnected through RS485 communication cables to achieve information synchronization and command broadcasting.

The master-slave mode has the following characteristics: 

  •  Support for setting the master battery 
  • Guarantee of consistent status among multiple batteries 
  • Maximum parallel quantity supported: V2.0 supports up to 15 parallel units; V3.0 supports up to 32 parallel units

This master-slave communication mechanism simplifies system wiring and configuration, enhances overall operational stability and scalability, and is suitable for a variety of scenarios such as residential expansion and commercial parallel systems.

III. Communication Compatibility Between Battery and Inverter

To achieve intelligent control of energy storage systems, effective communication between the battery and the inverter is crucial. The 48V 100Ah server rack battery from ECO-WORTHY supports a variety of mainstream protocols and interfaces, enabling seamless integration with major brands of energy storage inverters on the market.  Communication interfaces supported: RS485, CAN

Examples of Compatible Brands: Growatt, Deye, Victron, Voltronic, SRNE, Pylontech protocol compatibility, etc. Through the protocols, the battery can upload operating parameters such as SOC (State of Charge), voltage, current, and temperature to the inverter and receive its charge-discharge control signals, achieving system coordinated control.

The supported protocol configuration methods include DIP switch settings and upper computer software settings, catering to the needs of different customers.

IV. Communication Support with APP/Host Computer/SA/HA

To achieve remote monitoring and customized data retrieval, the battery also provides communication capabilities with upper computers, system aggregators (SA), and home automation platforms (HA). 

 

APP Wireless Communication (Supported by V2.0 and V3.0): Bluetooth / WiFi 

 

Communication Cables: RS485 to USB, RS232 to USB  

 

Application Examples: 

- JBD host computer on PC (via USB Serial Port): Real-time parameter reading and firmware upgrades. 

- SA (Solar Assistant) Based on Raspberry Pi: Collects information from multiple battery groups and uploads it to the cloud platform. 

- HA Platform (Home Assistant): Supports multi-platform access and, through the BMS_BLE-HA library, can easily connect with our batteries to achieve smart home integration. 

 

This functionality enhances the system compatibility of the battery, providing a technical foundation for remote data integration and intelligent energy management.

V. A “Communicative” Smart Battery

The ability to communicate is becoming an important hallmark of the “intelligence” of lithium batteries. The ECO-WORTHY 48V 100Ah server rack battery achieves comprehensive interconnection from the battery itself to the entire energy storage system by supporting a variety of communication protocols, interfaces, and platforms. 

 

This means that: 

- Users can achieve automated control and remote monitoring. 

- System integrators can quickly deploy and reduce compatibility challenges. 

 

A “communicative” battery is the key starting point for realizing a smart energy storage system.
