High-Voltage LiFePO4 Energy Storage System
10.24kWh per module | Up to 980V system voltage | ≥6,000 cycles | Dual-layer BMS protection | CE & UN38.3 certified
A modular, scalable high-voltage LiFePO4 system built for homeowners and commercial operators who demand reliable, long-term power independence.
Each RAKOUR 200Ah LiFePO4 battery module uses Grade-A lithium iron phosphate cells, delivering 10.24kWh of stable energy per unit. The inherently safe LiFePO4 chemistry eliminates the thermal runaway risk that affects NMC alternatives.
Connect 4 to 17 modules in series to reach system voltages from 185.6V to 980V. Run up to four parallel strings simultaneously, allowing installers to build systems exceeding 174kWh without any major cabinet redesign.
A built-in WIFI module syncs with a front-mounted dedicated touch color screen, giving operators remote access to live voltage, current, SOC, and temperature data from any smartphone or tablet without additional hardware.
Every electrical, physical, and communication parameter needed to verify compatibility, plan system sizing, and confirm compliance before committing to purchase.
Rated at 51.2V with 200Ah capacity, this lithium battery 200Ah module delivers 10.24kWh total energy and 9.22kWh usable at 90% DOD. Maximum continuous discharge current is 100A, supporting up to 5,120W output per module.
Each module weighs 77kg with a compact 396×575×248mm footprint. Discharge operates from −20°C to 60°C; charging from 0°C to 60°C. Humidity tolerance reaches 85% RH with an IP20 enclosure protection rating standard.
CAN and RS485 ports ensure compatibility with all major high-voltage inverter brands. Rated cycle life is ≥6,000 full cycles under standard conditions, with a 5-year product warranty covered by RAKOUR and CE, UN38.3 certifications.
A BCU master controller and a per-module slave BMS work in tandem, giving RAKOUR's high voltage battery system two independent protection layers no single-BMS design can replicate.
The Battery Control Unit houses a master BMS battery management system that consolidates voltage, current, and temperature data from every module via internal CAN. It independently controls charge circuits, discharge circuits, and protective cut-off responses.
Every 51.2V module runs its own slave BMS that tracks individual cell groups in real time. Automatic cell balancing runs during every charge cycle, preserving LiFePO4 battery life and preventing capacity divergence across stacked modules.
An embedded soft-start circuit absorbs inrush current at startup, protecting inverters that lack built-in soft-start capability. Charge, discharge, and balance states switch automatically based on real-time BMS readings without operator input.
LiFePO4 is inherently safer than NMC or lead-acid, and RAKOUR layers six hardware and firmware safeguards on top for continuous 24/7 operation.
The LiFePO4 battery uses iron-phosphate molecular bonds that stay stable under overcharge, heat, and physical stress. Unlike NMC cells, LiFePO4 does not release oxygen when compromised, removing the primary trigger of lithium battery fires.
RAKOUR's integrated LiFePO4 BMS activates protection against over-charge, over-discharge, over-current, short circuit, and high or low temperature faults simultaneously. A built-in DC fuse and hardware cut-off switch serve as the final failsafe layer.
Each module includes a dedicated cooling fan that activates automatically when internal temperature rises beyond threshold. The perforated sheet-metal housing promotes passive airflow between active fan cycles, ensuring stable thermal conditions without manual maintenance.
From single-home solar backup to large commercial installations, the 51.2V 200Ah system adapts to real energy demands without redesigning.
Pair the system with a rooftop solar array to capture excess daytime generation and discharge during outages. A 5-module stack delivers 51.2kWh — enough to power an average home for over two full days without grid input.
Deploy RAKOUR's energy storage system at commercial sites to reduce peak-demand charges. The 185.6V–980V operating range pairs with 30–80kW commercial high-voltage inverters directly, eliminating step-up transformer costs.
A discharge range of −20°C to 60°C makes this unit reliable for telecom base stations and UPS systems in extreme climates. The built-in soft-start circuit prevents inrush damage to sensitive communication equipment at startup.
Knowing when battery series vs parallel architecture is appropriate saves budget and prevents inverter mismatches before procurement begins.
Operating at 185.6V–980V instead of 48V means far lower current for equivalent power. Lower current requires thinner DC cables, smaller fuses, and less wiring labor — savings that scale significantly on larger commercial projects.
RAKOUR uses LiFePO4 across all product lines. LiFePO4 vs lithium ion data consistently shows LFP outlasts NMC by 2–3× in cycle life, while operating safely without thermal runaway suppression hardware.
Projects below 10kW with standard 48V inverters are better suited to RAKOUR's LV rackable series. The HV 200Ah system targets 20kW+ projects where high-voltage inverter compatibility is already confirmed and wiring runs are long.
Correct wiring and communication setup determine system efficiency. These steps reflect RAKOUR's verified installation procedure for the 51.2V 200Ah HV module series.
Stack modules bottom-to-top inside the iron frame, aligning positioning holes before fastening. Connect P1+/P1− and P2+/P2− on the BCU to the inverter's BAT1 and BAT2 DC ports for parallel-shunt current sharing.
Link the BCU CAN port to inverter BMS1 via RJ45 cable. Set the host address to 1 via DIP switch, then slave addresses 2–4 in sequence. RAKOUR provides verified Deye 29.9K–80K communication profiles ready for deployment.
Verify voltage difference stays within 1V before adding a parallel 48v lithium battery string. RAKOUR recommends matching production batches across all modules to maintain cell balance and preserve full warranty coverage.
Every 51.2V 200Ah unit ships with third-party-verified documentation — compliance records distributors and installers can present directly to end customers during procurement.
The 51.2V 200Ah HV module holds CE, UN38.3, and MSDS certification. Select models in the RAKOUR lineup additionally carry IEC62619 and ROHS compliance, covering stationary storage safety and hazardous substance restrictions.
RAKOUR guarantees every unit for 5 years under normal operating conditions. Lithium battery lifespan exceeds 6,000 full cycles before reaching 80% retention — equivalent to over 16 years at one complete daily cycle.
Xiamen Rakour Technology Co., Ltd. offers full OEM and ODM programs. Distributors can request custom voltage ranges, branded enclosures, or protocol adaptations. Contact RAKOUR for project-specific requirements and volume pricing.

RAKOUR's 51.2V 200Ah is rated for ≥6,000 full cycles before capacity drops below 80% — 2–3× longer than NMC. At one daily cycle, that exceeds 16 years of reliable service under standard conditions.
RAKOUR's BMS guards against over-charge, over-discharge, over-current, short circuit, and temperature faults. The BCU master runs a soft-start circuit, stopping inrush current damage to inverters.
