SOK SK48V100N 48V 100Ah server rack LiFePO4 battery 4-pack: four 5.12 kWh 3U batteries for 20.48 kWh of storage, each with a 100 A BMS, a built-in heater, Bluetooth monitoring and RS485 and CAN inverter communication. SOK sells the SK48V100N in sets of four, and this listing is the full set. The batteries talk to Victron, SMA, Growatt, Deye, Sol-Ark and other inverters over RS485 or CAN, assign their own addresses when linked, and scale to 48 batteries in parallel. Each has a 100 W heater for cold spaces, and Bluetooth lets you check every battery and update firmware from your phone. Backed by SOK's 7-year limited warranty.

πŸ”‹ Is It Right for Your System?

Built for 48V systems with a compatible 48V inverter. Common uses:

  • Home solar storage
  • Off-grid homes
  • Whole-home backup
  • Shops & barns
  • Victron & Sol-Ark systems
πŸ“ Quick check before you order:
  • Sold as a set of 4. SOK sells the SK48V100N only in sets of four batteries.
  • Your inverter is 48V and supports closed-loop battery communication over RS485 or CAN (SOK names Victron, SMA, Growatt, Deye and Sol-Ark). Tell us your inverter and we'll confirm.
  • You'll install it indoors. The battery is IP20, for a dry, ventilated space.
  • Each battery handles 100 A continuous, so the set provides up to 400 A combined, within your inverter's and cabling's limits.
  • You have room for four 3U batteries in a 19-inch rack or cabinet, or you'll add SOK's bracket rack or cabinet (sold separately). Each battery weighs about 106 lb (about 424 lb for the set).
  • Need UL? SOK lists only UN38.3 for the SK48V100N, not UL 1973 or UL 9540. Check with your inspector before you buy.
Not sure? Tell us what you're powering and we'll size it before you buy.

❓ Common Questions

Can I buy just one battery?
No. SOK sells the SK48V100N in sets of four, so this listing is a 4-pack. You can add more sets later, up to 48 batteries in parallel.
Will it work with my inverter?
SOK says it supports closed-loop communication over RS485 and CAN with Victron, SMA, Growatt, Deye, Sol-Ark and other inverters, and you choose the protocol in the app. Tell us your inverter and we'll confirm.
How do I add more batteries?
Connect them with the parallel cables and communication link. The batteries assign their own addresses and master/slave roles, with no DIP switches, up to 48 in parallel.
Does it have a screen?
No. It has RUN, ALM and SOC lights and a power switch. Use the Bluetooth app or your inverter's display for full data.
Is it UL listed?
SOK lists UN38.3 for the SK48V100N but no UL 1973 or UL 9540 certification. Check with your inspector before you buy.
How does the warranty work?
SOK covers it for 7 years from the purchase date with repair or replacement. Contact us first and we'll help you open an RMA with SOK. Under SOK's terms, the customer prepays shipping for warranty returns.
