What Is an EG4 Rack Battery and How Does It Work?
An EG4 rack battery is a lithium iron phosphate (LiFePO4) energy storage system designed for server rack mounting and low-voltage applications like homes and off-grid projects. It stores energy safely and efficiently within lithium cells, managed by an integrated Battery Management System (BMS), and delivers power on demand. Its modular design, advanced communication, and embedded safety features make it a reliable, scalable choice for modern energy storage.
How does the EG4 rack battery store and manage energy?
The EG4 rack battery uses LiFePO4 cells to store electrical energy with high stability and safety. An internal BMS continuously monitors voltage, current, and temperature of each cell, balancing the battery pack performance and protecting against faults such as overcharge, over-discharge, and overheating, ensuring safety and longevity.
What communication capabilities does the EG4 support?
EG4 batteries communicate via RS485 and CAN bus protocols, enabling integration with various inverters and monitoring software. This facilitates closed-loop control, real-time status monitoring, and easy system diagnostics through PC software or compatible inverters.
How does the modular design benefit EG4 batteries?
The EG4’s modular construction allows up to 64 batteries to connect in parallel, providing scalable energy capacity to match expanding system requirements. This flexibility supports a range of applications from small residential setups to large commercial or off-grid power systems.
What built-in safety mechanisms protect the EG4 rack battery?
Safety features include dual onboard aerosol fire arrestors as a last line of defense against thermal runaway, an emergency stop (E-Stop) and rapid shutdown (RSD) capability for critical interventions, and an internal circuit breaker for overcurrent protection. These layers ensure fail-safe operations in high-risk environments.
How long can an EG4 rack battery be expected to last?
EG4 batteries offer a long operational life with a cycle count exceeding 6,000 deep discharge cycles at 80% depth of discharge (DoD), translating into over 15 years of reliable usage under typical daily cycling conditions.
