Description

SRNE SR-Ket60A High Voltage Lithium Battery ESS

Industrial-Grade Energy Storage for C&I Applications

The SR-Ket60A is a high-voltage (HV) Lithium Iron Phosphate (LiFePO4) battery system specifically designed for commercial and industrial (C&I) solar solutions. Featuring a modular, rack-mounted design, it provides massive energy density and high-voltage efficiency, making it the perfect partner for the SRNE 60kW Three-Phase Hybrid Inverter.

Core Engineering Highlights

High-Voltage Efficiency: By connecting 12 modules in series, the system reaches a nominal voltage of 614.4V. This high-voltage architecture minimizes energy loss during power conversion and allows for thinner, more cost-effective cabling compared to traditional 48V systems.
Modular Scalability: The system starts at 61.4kWh and can be expanded by adding more racks in parallel, allowing businesses to scale their storage from small workshops to large-scale manufacturing plants.
Extreme Durability & Safety: Built with LiFePO4 cells—the safest lithium chemistry available. The system includes “Triple Protection” (Positive Relay + Negative Relay + Breaker) to ensure total electrical isolation during a fault.
Intelligent BMS: The integrated Battery Management System (BMS) provides cell-level monitoring, balancing current and voltage across all 12 modules to ensure a long service life of 6,000+ cycles.
Cable Sizing: For the HV DC link, use $35\text{mm}^2$ orange-shielded high-voltage DC cables rated for $1000\text{V}$ .
Grounding: The cabinet must be grounded with a $16\text{mm}^2$ $16\text{mm}^2$ copper conductor to the main building earth bar to ensure the BMS surge protection functions correctly.
Inverter Pairing: When commissioning, the “Battery Type” on the SRNE 60kW Inverter must be set to “Lithium” with the protocol selected as “SRNE-CAN”.
mart Monitoring: Fully compatible with Wi-Fi and Bluetooth for remote monitoring via the Tuya Cloud platform or the SRNE dedicated App.

Extended Technical Architecture: SR-Ket60A

The SR-Ket60A is not just a battery; it is an integrated energy ecosystem. It uses a Series-First architecture to achieve high DC bus voltages, which is the gold standard for modern Commercial & Industrial (C&I) storage.

1. Advanced Battery Module: SR-HOC05B

Each of the 12 modules in the stack is a self-contained power unit.
- Cell Chemistry: Lithium Iron Phosphate (LiFePO4).
- Module Voltage: $51.2\text{V}$ nominal.
- Module Capacity: $100\text{Ah}$ ( $5.12\text{kWh}$ ).
- Individual BMS: Every module contains its own slave BMS to monitor cell-level voltage and temperature, reporting back to the Master PDU.
2. Master Control: SR-PDU100 (Power Distribution Unit)

The PDU is the “brain” of the stack. It manages the electrical connection between the high-voltage DC bus and the inverter.
- System Protection: Integrated high-voltage DC contactors and a $125\text{A}$ $125\text{A}$ Circuit Breaker.
- Pre-charge Circuit: Built-in pre-charge resistor to prevent massive inrush currents when connecting to large inverter capacitor banks.
- Dual-Communication: * Internal: RS485 for module-to-module synchronization.
  - External: CAN-bus for high-speed inverter-to-battery handshake.
3. Operational Logic & Efficiency
- Round-Trip Efficiency (RTE): $\ge 95\%$ . Because the voltage is high ( $614.4\text{V}$ ), the current required to move 60kW of power is much lower than a 48V system.
  - Example: To move 60kW at 48V, you need 1,250A. At 600V, you only need 100A. This reduces wire heat and energy loss significantly.
- Self-Consumption: less than 5w in Sleep Mode / $< 30\text{W}$ in Operating Mode.
