The Epoch 48V 100Ah server rack battery is a self-heating 5.12kWh lithium battery built for DIY solar builders, off-grid homeowners, and professional installers. This Epoch 48V battery combines a compact 3U rack mount lithium battery chassis with CAN/RS485 communication, parallel expansion up to 32 batteries, 6,000+ cycle life, and active heating support for cold-climate energy storage. Build a clean 48V home solar backup system that can grow with your power needs. Rack mount home energy storage 51.2V Nominal voltage 100Ah Capacity 5.12kWh Nominal energy 3U Rack height 100A Discharge 32x Parallel ready Built for energy storage systems 11-year warranty Manufacturer coverage 6,000+ cycles Long service life Self-heating Cold-climate charging CAN / RS485 Inverter communication 3U rack mount Space-saving cabinet fit Advanced BMS Built-in protection Seamless Closed-Loop Inverter Communications CAN/RS485 ports for smarter 48V home solar backup and off-grid power wall systems. For technical buyers, inverter communication is often the deciding factor. The Epoch SR48100H includes CAN and RS485 communication ports so the BMS can share battery status, charge and discharge limits, and state-of-charge data with compatible inverter systems. The supported inverter ecosystem includes popular brands such as Victron, Sol-Ark, Growatt, SMA, Deye, Sunsynk, Solis, Schneider, Luxpower, Goodwe, Studer, Voltronic, Alpha-Outback, Sofar, SAJ, MEGAREVO, TBB, and MPP. Always confirm the correct DIP/protocol setting, cable pinout, and inverter firmware before commissioning. Built for Cold Climates: Active Self-Heating Technology A self-heating server rack battery for unheated garages, barns, shops, and cabins. Many standard rack batteries require climate-controlled utility rooms. This Epoch battery uses internal heating support so the system can warm the cells with incoming charge current before charging in cold conditions. The specification lists heating start conditions from -25°C to 5°C when incoming current is available, with heating completing once the battery reaches a safe temperature threshold. This makes it a strong option for protected cold-climate installs where winter charging support matters. Massive Scalability: Build Your Ultimate Power Wall Start with 5.12kWh. Scale your 48V battery bank as your loads grow. One battery stores 5.12kWh nominal energy, making it an excellent building block for solar backup, emergency power, and off-grid ESS projects. When your power needs grow, the SR48100H supports plug-and-play parallel expansion. Wire multiple batteries in parallel to grow from a single 5.12kWh starter system to larger banks. Epoch lists support for up to 32 batteries in parallel, allowing large rack-based 48V storage systems when installed with proper communication, busbars, overcurrent protection, and qualified system design. Enterprise-Grade Safety, Certifications & 11-Year Warranty Purpose-built for serious home energy storage and off-grid power systems. Standard 3U Size & Rack Integration The 3U form factor is designed for standard 19-inch server racks, telecom racks, and solar battery cabinets. This keeps wire management clean and allows builders to stack batteries vertically to save floor space. Code Compliance & 6,000+ Cycle Life The battery is positioned as UL9540 pending and includes a smart BMS with overcharge, over-discharge, over-current, short-circuit, and high/low temperature protections. Always confirm current certification paperwork with Epoch and the local authority having jurisdiction before permitting a grid-connected ESS.
