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.

Closed-loop communication is strongly recommended
Let the BMS and inverter manage the system together.
The specification notes that communication between the battery and inverter is important to maximize dynamic performance and lifespan. Configure the correct protocol, communication cable, DIP settings, and charge/discharge limits before commissioning the system.
Fitment and installation note
Verify the complete system before installation.
Installation should be performed by qualified personnel. Confirm rack depth, rack weight rating, ventilation, grounding, battery-to-battery communication wiring, inverter protocol, DC cable sizing, breaker/fuse sizing, torque, and local code requirements before installation. Always follow Epoch’s latest manual, inverter documentation, and local electrical code.
Frequently asked questions
48V 100Ah Server Rack Battery FAQs
Common questions about inverter communication, self-heating, racks, parallel expansion, and permitting.
Which inverters does this battery communicate with?
The Epoch 48V 100Ah server rack battery includes built-in CAN and RS485 communication ports for closed-loop inverter communication. The current compatibility list includes Victron, Sol-Ark, Growatt, SMA, Deye, Sunsynk, Solis, Schneider, Luxpower, Goodwe, Studer, Voltronic, Alpha-Outback, Sofar, SAJ, MEGAREVO, TBB, and MPP. Always confirm the current protocol setting and cable requirements for your specific inverter before commissioning.
Can I install these batteries in my unheated garage?
Yes, when the space is dry and protected. This self-heating server rack battery is designed to support cold-climate charging by using incoming charge current to warm the cells before charging. It is still an IP20 indoor-use battery, so it should be installed in a dry garage, utility room, shop, barn, or battery cabinet rather than outdoors or in wet locations.
What is the continuous output of a single 48V 100Ah battery?
A single unit is rated for 100A maximum continuous discharge. At 51.2V nominal, that equals roughly 5,120 watts of DC output. For large inverters, well pumps, compressors, or high-surge tools, it is best to size the inverter and battery bank together and often use multiple batteries in parallel for extra surge headroom and lower stress per battery.
What does 3U mean, and what size rack do I need?
3U refers to the vertical rack height. One rack unit is 1.75 inches, so a 3U battery is about 5.25 inches tall. This battery is designed for standard 19-inch rack and cabinet systems, with listed dimensions of 17.4 inches by 18.1 inches by 5.2 inches.
Why is UL9540 pending important?
Home energy storage projects often require approval from the local authority having jurisdiction, utility, or fire marshal. UL9540 pending status indicates the product is positioned for energy storage system compliance, but final permitting requirements vary by jurisdiction. Always confirm the latest Epoch certification documents, inverter pairing, and submittal package before permitting a grid-connected ESS.
Can I wire these server rack batteries in series?
No. These are native 48V / 51.2V batteries designed for parallel expansion only. Wiring them in series to create a higher-voltage system can damage the BMS and void the warranty. Use the listed plug-and-play parallel configuration to increase amp-hours and kilowatt-hours.
How many batteries can I connect in parallel?
Epoch lists support for up to 32 batteries in parallel. That allows a system to scale from a single 5.12kWh starter battery to a very large battery bank when properly designed with correct communication wiring, busbars, breakers, fusing, rack hardware, and inverter settings.
Is this battery waterproof?
No. This is an IP20 server rack battery intended for protected indoor use. It should be installed in a dry, clean, ventilated environment such as a utility room, rack cabinet, battery room, shop, or protected garage. It is not an IP67 outdoor battery and should not be exposed to rain, washdown, bilge water, or moisture.
What charger settings should I use?
The official specification lists a 56.0V charge voltage and 54.6V float voltage, with up to 70A maximum charge current and 50A recommended charge current. For inverter/charger systems, use the correct closed-loop protocol whenever available so the BMS can communicate charge and discharge limits dynamically.
