The SOK 48V Server Rack Battery: Power and Convenience Combined
The SOK 48V Server Rack Battery is a 5.12kWh rack battery with a modular and user-serviceable design. Whether you need to power a whole home system, a datacenter or a telecom room, this battery delivers remarkable capacity in a minimal amount of space.
Uncompromising Quality and Safety
SOK has a longstanding reputation for delivering exceptional quality and safety at a value-conscious price point, and the SK48V100 is no exception. This Grade A+ Lithium Iron Phosphate (LiFePO4) battery pack is designed to seamlessly fit into standard 19” EIA server-rack type battery enclosures or the custom-built SOK Server Rack. With a 16S (48V nominal) 5.12 kW-h LiFePO4 battery bank and a battery management system (BMS), the SK48V100 ensures automated and maintenance-free battery operation, offering a typical lifespan of over 4000 cycles.
Versatility and Expandability
The SK48V100 battery is an ideal choice for medium to large-scale off-grid, grid-interactive energy storage systems (ESS), server and backup applications. Its reliability, quality, expandability, and serviceability make it a perfect fit for a wide range of applications.
Key Features:
- User-Serviceable Design: The SOK battery allows field servicing, unlike competing batteries that are permanently sealed and non-serviceable. You can replace every component within the battery pack with just a Phillips screwdriver and a 10mm wrench.
- Enhanced Safety Features: The built-in smart BMS provides comprehensive protection against overcharging, discharging, and short circuits. It also features low temperature charging protection, ensuring optimal performance even in extreme conditions.
- Extended Cycle Life: The SK48V100 offers impressive longevity and reliability with high-capacity cells that retain 80% capacity after 4000 cycles. That is even at a 100% Depth of Discharge (DOD) with a 1C rate.
- Seamless Communication: The battery supports RS485 and CANBus communication protocols when using the appropriate communication cables.
- Quick and Easy Installation: This battery is designed for rack mounting for a quick and easy setup.
Certification
UL9540 Certification (Pending): The certification process is currently in progress, providing added assurance of quality and safety. The SOK Battery SK48V100 is built to meet the highest industry standards.
Long-Term Assurance and Warranty
At Current Connected, we stand behind the quality and durability of our products. The SK48V100 battery comes with a 10-year manufacturers’ warranty.

Can it do closed-loop communications with Schneider XW Pro inverter/charger?
While there is a way to make it work, we do not support communication between a Schneider and SOK. We would recommend going with the EG4-LL as communication is supported.

My setup uses four of the SOK 48V 100Ah PRO batteries in conjunction with Victron hardware including a Cerbo GX and 48V Quattro inverter. Would a system like this benefit from a battery shunt/monitor such as the Victron SmartShunt or does the SOK's built in battery monitor make a shunt unnecessary?
The shunt is not a requirement as the built in BMS would properly monitor the batteries. That being said, the shunt would more accurate.

Totally Off Grid Application: Is closed loop communication with SMA Sunny Island available?
Closed loop communication is not supported. If you choose either battery for use with a Sunny Island we would recommend using a Chargeverter. Using the Sunny Island to control charging without closed loop communication is not ideal.

Do the batter cable covers that come in the battery box the same size as the ones you sell on your website for fitting 1/0 - 4/0 cables? The covers that come in the box seem too small for the 2/0 cables that came in the kit I purchased.
The covers in the box are for 6AWG ~ 2AWG. We offer larger covers on our site that support up 1/0 ~ 4/0, and if you purchase our 5-battery kit, we include these larger covers with the kit.

Not listed, but to be certain... can these batteries communicate with a Magnum MS4448PAE?
They do not support closed-loop communication, however, you can use voltage-based control by setting your absorption voltage at 57.6v, float voltage at 55.2v and low-voltage shutdown at 48v. It would work just fine for your application!

What is the recommended standalone charger for these batteries? I'm having a hard time finding one that operates below 58.4v that other chargers seem to aim for.
We would recommend using the EG 4 Chargeverter.

What is the stud size on the terminals? 1/2"? 3/8"? Can't find this info in your online manual.
Great question! They are M8x1.25 - for a ring terminal it would be best to use a 5/16" diameter terminal. The recommended torque for tightening these terminals is 15 Ft-lbs
[email protected] asked: January 5, 2023
Is there any sort of terminal cover available for the SOK server rack batteries for the unused terminals (that are not connected to a bus bar or cable)?
Not currently, we are working on one. At this time, we do not have a solid eta.

Can the SOK server rack batteries be positioned vertically; either on their ends or sides?
In certain applications, Yes! We have a full page in the instruction manual dedicated to this question. You can check it out here: https://www.currentconnected.com/sk48v100/manual-2-4/
Dexter asked: December 17, 2022
If my inverter doesn't communicate, can I still use this battery?
Yes, however you will need to manually set the appropriate settings within the inverter manually, and run these batteries in an open-loop, voltage control based configuration.

Dexter asked: December 17, 2022
Is this compatible with Sol-Ark Inverters?
Yes! An added bonus is that this battery supports full closed-loop communication with ALL Sol-Ark Inverters. In fact this is the easiest inverter on the market to setup battery communications with. You can read more about this battery communicating with the inverter over in the instruction manual page dedicated to Sol-Ark Inverters here: https://www.currentconnected.com/sk48v100/manual-4-4/
