Commercial Battery Storage Solutions for Business & Industry
What Energy Challenges Does Commercial Battery Storage Solve?
Rising electricity tariffs, unpredictable grid outages, and growing carbon reduction mandates put constant pressure on commercial and industrial facilities. RAKOUR's commercial battery storage solutions are engineered to address these challenges directly — helping businesses take control of energy costs and operational continuity.
Peak Shaving and Demand Charge Reduction
Demand charges can account for up to 50% of a commercial electricity bill. RAKOUR's high voltage LiFePO4 systems — such as the 51.2V314Ah-HV series with capacities from 115 kWh to 244 kWh per set — store energy during off-peak hours and discharge during demand peaks, significantly reducing monthly utility costs.
Behind the Meter Energy Storage for Business Operations
Deployed behind the meter, RAKOUR energy storage systems work alongside existing grid connections to optimize self-consumption, provide instant backup during outages, and support automatic diesel generator switching — as demonstrated in our 100kW/174kWh outdoor integrated cabinet solution.
Three Key Scenarios: Factory, Data Center & Solar-Storage-EV
RAKOUR serves three core C&I scenarios: industrial park peak management, data center uninterruptible power supply, and integrated solar-storage-EV charging stations. Each scenario links to a dedicated solution page with detailed system configurations.
High Voltage vs Low Voltage Battery Energy Storage System
Choosing the right system architecture is a critical first step for any C&I project. RAKOUR offers both high voltage and low voltage LiFePO4 battery energy storage systems, allowing EPC contractors and system integrators to match the architecture precisely to project requirements.
When to Choose a High Voltage Battery System
RAKOUR's HV series connects 8–17 battery modules (51.2V each) in series through a centralized BCU, achieving an operating voltage range of 358.4V–979.2V and up to 243.71 kWh per set. With 4-set parallel capability, total capacity reaches nearly 1 MWh. This architecture is ideal for large factories and industrial parks where high power output and efficient long-distance DC transmission are required.
Low Voltage Server Rack Battery for Small-Scale C&I
For smaller commercial facilities, RAKOUR's LV rackable series operates at 51.2V with capacities of 100Ah, 200Ah, 280Ah, and 314Ah per module. Each server rack battery supports up to 15 units in parallel, scaling from 5.12 kWh to over 241 kWh. The compact rack-mount form factor fits standard IT cabinets, making it well suited for retail stores, small offices, and telecom sites.

Battery Inverter Compatibility for Seamless Integration
For EPC contractors and system integrators, inverter compatibility is often the make-or-break factor in project delivery. A communication mismatch between battery and inverter can cause charging failures, safety shutdowns, or degraded performance. RAKOUR eliminates this risk with pre-tested integration across multiple mainstream inverter brands.
Verified Inverter Brands: Deye, Goodwe, SMA & More
RAKOUR's HV series has been tested and documented for direct connection with Deye hybrid inverters, including the 29.9K–50K and 80KW series. The BMS communicates with the inverter in real time, dynamically controlling charging voltage, charging current, and discharge cut-off parameters. Detailed wiring diagrams and step-by-step configuration guides are provided for each verified inverter model. Compatibility testing with Goodwe, SMA, and other brands is ongoing, with documentation updated regularly.
Communication Protocols: CAN Bus and RS485 Explained
All RAKOUR battery systems feature dual communication interfaces via standard RJ45 ports: CAN Bus and RS485 for inverter communication, plus RS232 for system configuration. The built-in touch screen on the LV rackable series allows installers to switch communication protocols on-site — no laptop or special software required — ensuring fast adaptation to different inverter brands during commissioning.
Intelligent Battery Management System for C&I Operations
In commercial and industrial energy storage, the BMS battery management system determines whether a project runs safely, efficiently, and profitably over its full lifecycle. RAKOUR integrates a hierarchical BMS architecture across all product lines — with a master BMS in the BCU and slave BMS in each battery module — to deliver multi-layered protection and real-time intelligence.
BMS Battery Management System: Core Protection Features
Every RAKOUR system monitors voltage, current, and temperature at the individual cell level. The BMS provides five critical protections: overcharge, over-discharge, overcurrent, high temperature, and low temperature cutoff. It also performs active cell balancing during charging to prevent capacity drift between cells — a key factor in extending cycle life beyond 8,000 cycles. All protection functions have been independently verified under IEC 62619 testing, with results confirming that overcurrent and overheating sensors operated correctly and no fire or explosion occurred.
Remote Monitoring and Smart Energy Management via WiFi
RAKOUR's HV series includes a built-in wireless WiFi module that enables remote monitoring and parameter adjustment via a mobile app. Distributors and EPC teams can track real-time SOC, cell voltage, temperature, cumulative charge/discharge capacity, and SOH — from anywhere. The LV rackable series offers an on-unit touch color screen for local diagnostics, with optional WiFi and Bluetooth connectivity for remote access.
Modular and Scalable Battery Storage System Design
C&I energy demands rarely stay static. A facility that needs 50 kWh today may require 200 kWh within two years as operations expand. RAKOUR's modular architecture lets EPC contractors and distributors deploy the right capacity now and scale incrementally — without replacing existing equipment.
Parallel Expansion from 16kWh to 240kWh+
RAKOUR's HV rackable series supports up to 15 units in parallel, scaling a single 51.2V314Ah module (16 kWh) to over 241 kWh. The HV series takes a different path: 8–17 modules connect in series within a single set, and up to 4 sets can be paralleled — reaching nearly 1 MWh of total storage. For parallel installation, the voltage difference between units must stay within 1V, and RAKOUR recommends modules produced within the same 12-month period to maintain optimal capacity balance.
Plug-and-Play Modular Design for Faster Deployment
Each battery module is designed for tool-minimal stacking using alignment bolts and corner-mounted sheet metal brackets. Installers can choose between open-frame rack assembly or enclosed battery cabinet configurations — both available through RAKOUR's authorized channel. The dip-switch addressing system assigns each unit a unique BMS address (1 through 15), enabling automatic master-slave coordination without complex software setup. This plug-and-play approach significantly reduces commissioning time on site.
Global Certifications: UL 9540, UN38.3, CE and Beyond
No certification means no installation. For EPC contractors, distributors, and system integrators working across international markets, verified compliance documentation is a non-negotiable requirement before any procurement decision. RAKOUR maintains a comprehensive certification portfolio covering product safety, electromagnetic compatibility, and transportation regulations.

Industrial Park Peak Shaving with Battery Container System
RAKOUR's 300kW/522kWh outdoor integrated cabinet system — using three HV units in parallel — was deployed for an industrial park peak shaving application. The system charges during off-peak grid hours and discharges during demand peaks, directly reducing the facility's monthly demand charges. The containerized design enables rapid on-site installation with minimal civil work.
Data Center Backup Power Deployment
A 100kW/174kWh outdoor all-in-one cabinet was configured with automatic diesel generator switching for a data center backup power scenario. When grid power fails, the RAKOUR battery system responds instantly while the diesel generator starts up — providing seamless bridging power that eliminates downtime for mission-critical IT loads.
Solar-Storage-EV Charging Station Integration
RAKOUR's modular HV 314Ah series supports integrated solar-storage-EV charging configurations. The system stores excess solar generation during daytime hours and dispatches stored energy to EV chargers during peak evening demand — reducing grid dependency and enabling facility owners to monetize their rooftop solar assets more effectively.
