High Voltage Battery Energy Storage System for C&I Applications 

RAKOUR HV battery energy storage systems communicate via CAN and RS485 protocols, ensuring seamless integration with leading high-voltage inverters including Deye, SMA, Growatt, Victron, and Goodwe. The BCU's dual-port design supports simultaneous inverter and parallel communication without additional gateways.

RAKOUR HV BESS supports both AC-coupled and DC-coupled topologies. The built-in soft-start circuit allows integration with inverters lacking native soft-start, reducing commissioning complexity for EPC contractors and eliminating additional hardware costs on-site.

The touch color screen and Wi-Fi module enable remote debugging from mobile devices. Full technical documentation, wiring diagrams, and commissioning guides are provided in English, reducing integration risk for international system integrators and distributors working across multiple project sites.

The 51.2V314Ah-HV bess system scales from 5 to 17 modules per cabinet, delivering 80.38 kWh to 225.08 kWh per unit. The 51.2V200Ah-HV supports 4 to 17 modules, covering 40.96 kWh to 174.08 kWh. Both models use standardized 51.2V LiFePO4 modules enabling incremental capacity expansion.

RAKOUR HV cabinets support up to 4 sets in parallel, enabling EPC teams to deploy scalable energy storage systems exceeding 900 kWh from a single product line. Parallel communication ports are built into the BCU, eliminating the need for external controllers.

The 51.2V314Ah-HV operates between 232V and 979.2V DC, directly matching high-voltage PCS input windows. The 51.2V200Ah-HV covers 185.6V to 980V. This broad operating window gives integrators flexibility across inverter brands without custom adaptation.

Every RAKOUR HV module includes a slave BMU feeding real-time voltage and temperature data to the master battery management system in the BCU via internal CAN. The system triggers automatic protection against overcharge, over-discharge, overcurrent, and high or low temperature conditions without manual intervention.

Each battery module is equipped with a dedicated cooling fan and a porous sheet metal enclosure design that promotes airflow through the cell stack. Fans activate automatically when internal temperature rises, maintaining stable thermal conditions during high-load commercial discharge cycles.

The BCU integrates a DC fuse, soft-start circuit, and cut-off protection switch. These components isolate faults at module level, preventing cascade failures across parallel strings. This design meets the safety expectations of EPC project managers working under IEC and CE compliance requirements.

RAKOUR HV battery energy storage systems carry CE, MSDS, and UN38.3 certifications. Select LV models additionally hold IEC 62619 and RoHS, covering European market entry requirements. All certifications are documented at the full system level, not only at cell level, which satisfies EPC procurement due diligence.

CAN and RS485 communication ports built into the BCU comply with standard grid interconnection communication protocols used by utilities and aggregators across Europe, Southeast Asia, and Australia. No third-party communication gateway is required for most certified inverter models.

RAKOUR supplies complete system-level technical files, CE declarations, and test reports in English. This streamlines tender qualification and local authority permitting for EPC teams operating in multiple regions simultaneously.

The 51.2V200Ah-HV delivers ≥6,000 cycles while the 51.2V314Ah-HV achieves ≥8,000 cycles, both at 90% depth of discharge. This means a daily-cycle C&I commercial battery storage project can expect 16 to 22 years of usable service life from the LiFePO4 cell chemistry.

RAKOUR provides a 5-year warranty across all HV product lines, covering battery modules and BCU components. This warranty period aligns with standard EPC project financing terms and supports bankability assessments required by lenders and project investors.

The built-in Wi-Fi module streams SOC, voltage, current, and temperature data to the RAKOUR mobile app. EPC teams and O&M providers can monitor multiple sites remotely, reducing on-site inspection frequency and lowering long-term operations and maintenance costs.

RAKOUR HV bess battery systems are sized to support sustained discharge at rated power, enabling effective peak shaving during high-tariff grid periods. A single 314Ah 10-module cabinet delivers 102.4 kW of maximum power, sufficient to flatten demand peaks in medium-scale industrial facilities.

When paired with on-site solar, RAKOUR HV systems store excess generation during the day and discharge during peak tariff windows. This time-of-use strategy reduces electricity costs and shortens project payback periods, commonly achieving returns within 3 to 5 years in markets with demand charges above $12/kW.

RAKOUR systems provide verifiable cycle life data, full certification documentation, and warranty coverage that meets the bankability criteria used by project finance teams. Distributors can present these materials directly to end clients and financing institutions during the project development phase.

Xiamen RAKOUR Technology Co., Ltd. manufactures HV bess clean energy products at dedicated production facilities in Xiamen, China. Standardized module design and consistent production processes reduce batch-to-batch variation, giving EPC contractors predictable equipment performance across multi-site project rollouts.

RAKOUR provides datasheets, user manuals, installation guides, wiring diagrams, and certification documents in English for all HV product lines. This eliminates translation delays that frequently affect project timelines for EPC teams in Europe, the Middle East, and Southeast Asia.

RAKOUR supports OEM and ODM collaboration for distributors requiring customized branding, enclosure configurations, or communication protocol adaptations. This flexibility enables partners to differentiate their market offering while leveraging RAKOUR's validated battery energy storage system hardware platform.

RAKOUR HV industrial batteries integrate directly with rooftop or ground-mount solar PV systems via high-voltage hybrid inverters. The wide DC operating window accommodates both new builds using DC coupling and retrofit projects using ac coupled design solar bess configurations, covering factories, warehouses, and commercial buildings.

The RAKOUR HV series supports off-grid and islanding operation when paired with compatible inverters offering transfer switching. The system's operating temperature range of −20°C to 60°C for discharge makes it suitable for remote industrial sites, mining operations, and telecom base stations in harsh climate zones.

EPC contractors can deploy RAKOUR HV cabinets as demand response assets or frequency support reserves. The system's fast response BMS, combined with reliable CAN communication, enables participation in ancillary service programs offered by grid operators in liberalized electricity markets across Europe and Asia-Pacific.
