System Architecture — Modular High Voltage Battery Design
Dual-Layer BMS Architecture for Intelligent Cell Management
Integrated LiFePO4 Battery Management System for Maximum Safety
Key Features
Every unit ships with a built-in multi-layer BMS battery that monitors cell balancing, over-temperature, over-voltage, and short-circuit protection — ensuring long cycle life across 6,000+ charge cycles at 80% DoD.
Grade-A LiFePO4 Cells with ≥8,000 Cycle Life at 90% DoD
The RAKOUR NSTFW-16K-HV is built on Grade-A LiFePO4 cells configured in a 16S1P architecture per battery module. Rated at ≥8,000 cycles at 90% DoD, each 314Ah module delivers 16.08kWh of dependable capacity — significantly reducing total cost of ownership for long-duration commercial energy storage deployments.
Dual-Layer BMS Battery with Multi-Level Fault Protection
The integrated LiFePO4 battery management system operates on two levels: a slave BMS within each stackable battery module and a master BMS inside the BCU. The BMS battery monitors cell voltage, current, and temperature in real time, with active protection against overcharge, over-discharge, over-current, and high/low temperature events — ensuring autonomous, fail-safe operation across the full energy storage system.
Active Fan Cooling, Soft-Start Circuit & On-Board Display
Each battery module is equipped with an active cooling fan to manage thermal load during high-current operation. A built-in soft-start circuit enables compatibility with high voltage inverters that lack native soft-start functionality. The BCU integrates a touch screen display for real-time SOC, alarm status, and system parameter monitoring at the installation site.

EPC Projects
C&I Solar Energy Storage — On-Grid, Hybrid & Peak Shaving
The RAKOUR NSTFW-16K-HV is purpose-built for commercial and industrial solar energy storage deployments where high capacity, scalable architecture, and high voltage inverter compatibility are non-negotiable. With each rack delivering 16.08kWh and support for up to 17 battery stacks in parallel — each containing 5 to 14 modules — the system scales to meet large-load demand response, solar self-consumption maximization, and time-of-use peak shaving requirements on a single platform.
Grid Backup & Multi-Inverter AC Parallel Deployments
The NSTFW-16K-HV energy storage system supports up to 10 inverters in AC parallel operation, making it a viable backbone for microgrid, EPC-designed backup power installations, and multi-building commercial facilities. Its stackable battery architecture enables phased capacity expansion without system redesign — a critical advantage for EPCs and distributors delivering scalable commercial energy storage solutions to end clients.
Server Rack Battery Compatible With Leading High Voltage Inverter Brands
Compatible Inverters
This server rack battery communicates natively with major high voltage inverter brands via RS485 and CAN protocols, enabling plug-and-play commissioning for installers.
Verified DEYE High Voltage Inverter Integration — CAN Protocol
The RAKOUR NSTFW-16K-HV high voltage battery communicates with compatible high voltage inverters via CAN protocol, connecting the BCU's CAN port directly to the inverter's BMS1 port. Dedicated wiring and commissioning guides are available for two factory-verified DEYE configurations: the SUN-29.9K~50K-SG01HP3 and the SUN-80K-SG02HP3-EU-EM6. For DEYE 80kW series, parallel shunt wiring across dual BAT interfaces (P1+/P1− → BAT1, P2+/P2− → BAT2) is recommended to maximize discharge current from a single battery energy storage system cluster — reducing total hardware cost per kWh for EPC projects.
