Engineered with automotive-grade prismatic cells, multi-protocol smart BMS, and ultra-high thermal stability for seamless hybrid solar integration.
As the global energy transition accelerates toward localized renewable microgrids, the demand for high-density, inherently safe, and modular electrochemical energy storage has shifted decisively toward 19-inch rack-mounted lithium iron phosphate (LiFePO4) architectures. Modern residential solar storage, commercial farm installations, and telecom power backups require battery packs that offer seamless integration, thermal resilience, zero maintenance, and scalable expansion up to hundreds of kilowatt-hours.
As an ISO9001:2015 certified manufacturer with engineering lineage rooted in custom lithium-ion pack assembly, advanced hardware/firmware Battery Management Systems (BMS), and power conversion integration, our factory delivers server rack battery solutions built on strict automotive-grade cell screening and proprietary software control loops.
The core chemistry driving modern rack-mount solar storage is Lithium Iron Phosphate (LiFePO4). Compared to traditional Nickel Manganese Cobalt (NMC) or Lithium Titanate Oxide (LTO), LiFePO4 delivers the ideal equilibrium of thermal safety (decomposition temperature above 270°C), volumetric energy density, and cost-per-kWh cycle life for stationary storage installations.
Utilizing exclusively brand-new Tier-1 LiFePO4 prismatic cells (100Ah/200Ah/280Ah/314Ah) with internal resistance matching within ≤ 0.3mΩ and voltage delta within ≤ 5mV during automated cell-sorting.
Pre-programmed with auto-matching firmware for major global hybrid solar inverters, including Deye, Victron Energy, Growatt, Megarevo, Luxpower, Sol-Ark, SMA, and GoodWe via CAN 2.0B & RS485.
Equipped with dual solid-state relay protection or high-current air circuit breakers, thermal sensor harnesses across cell terminals, and optional aerosol auto fire-extinguishing pods.

As global energy procurement officers, engineering, procurement, and construction (EPC) contractors, and B2B distributors evaluate battery supplier options, understanding key technological shifts is paramount to avoiding premature obsolescence. Our engineering research team identifies four critical industry trends reshaping server rack energy storage:
Standard 50Ah and 100Ah pouch/cylindrical cells are rapidly being replaced by high-capacity 308Ah and 314Ah prismatic cells. This shift yields a 25% increase in energy volumetric density within standard 4U/5U rack frames without enlarging overall cabinet footprints.
Future-proof battery procurement prioritizes BMS boards integrated with Wi-Fi/4G cloud connectivity. Cloud-based telemetry provides real-time SOH (State of Health) prediction, localized cell degradation tracking, and automated thermal runaway warning systems.
While low-voltage 48V/51.2V systems remain dominant in residential installations, Commercial and Industrial (C&I) projects are migrating to high-voltage series racks (307V to 800V DC). HV architectures reduce copper cabling costs by up to 60% and improve inverter efficiency to over 98.8%.
By partnering directly with a qualified OEM manufacturer equipped with in-house hardware design, firmware compiling, and cell testing, procurement teams can customize battery enclosure dimensions, busbar cross-sections, and BMS protocol code to seamlessly match legacy and next-generation solar hardware.
Building on over 15 years of precision engineering heritage in UK-standard certified custom lithium-ion battery design, electronic development, and specialized power systems, our manufacturing facilities adhere to rigorous international quality control standards.
Every server rack pack undergoes automated capacity grading, high-pot isolation resistance testing, and 100% full-charge/discharge burn-in verification prior to packaging, ensuring batch-to-batch zero defect consistency.
We do not rely on third-party generic protection boards. Our proprietary BMS software platform (such as AlterVU integration) allows remote parameter configuration, custom protocol handshakes, and cell protection thresholds tuning.
Our rack batteries are certified under international transport and safety regulations including UN38.3 (Section 38.3 Lithium Metal/Ion Batteries), MSDS, CE-EMC, IEC 62619, and design compliance aligned with UL 1973 standards.
From custom silk-screen branding, bespoke front-panel LCD interface designs, customized metal enclosure colors, to custom communication pinouts, we provide scalable ODM solutions tailored for global distributors.
Our standard 48V/51.2V rack mount battery packs feature DIP-switch address selection supporting up to 16 modules in parallel without an extra controller hub (providing up to 80kWh–160kWh total capacity). For larger utility-scale requirements, adding a master BMS hub allows parallel pooling up to 32 clusters (over 2.5MWh).
Yes. Our smart BMS includes built-in firmware protocols for Deye, Victron Energy, Growatt, Megarevo, Luxpower, Sol-Ark, Voltronic, Schneider, GoodWe, and SMA. Changing inverter protocols takes seconds via the front LCD menu or via connection to our software interface.
Our factory utilizes Grade-A LiFePO4 cells offering ≥ 6,000 continuous charge/discharge cycles at 80% Depth of Discharge (DOD) under standard 25°C operating conditions. This translates to over 15 years of daily solar cycling performance before capacity reaches 70% of initial rating.
A 48V system uses 15 LiFePO4 cells in series (nominal 48.0V), while a 51.2V system uses 16 cells in series (nominal 51.2V). The 16S 51.2V configuration is currently the preferred global industry standard because its operational voltage curve matches modern off-grid/hybrid inverters more efficiently, maximizing energy extraction per cycle.
Every battery pack undergoes automated cell impedance sorting, laser welding inspection, BMS high-voltage isolation checks, and full load aging tests. All shipments are certified UN38.3 Dangerous Goods compliant with heavy-duty hazardous materials export packaging (UN-rated wooden crates or reinforced double-wall cartons).
Yes, as a factory direct supplier, we provide white-label OEM manufacturing including custom front-panel design, laser logo printing, bespoke sheet metal color powder-coating, custom user manuals, and customized CANbus firmware strings to display your brand on hybrid inverter screens.
