48V Server Rack LiFePO4 Batteries

SOK 48V server-rack LiFePO4 batteries are designed for whole-home solar, commercial off-grid, and standby backup applications. The SK48V100N drops into any standard 19-inch rack in a 3U footprint, talks to 30+ inverter brands (EG4, Sol-Ark, Schneider, Victron, MidNite Solar, Outback, Magnum, Growatt, and more) over CAN/RS485, and supports over-the-air firmware updates so the battery upgrades over time without removal.

Who This Is For

Whole-home solar installers, off-grid homeowners with 48V inverter systems (EG4 6000XP / 18kPV, Sol-Ark 12K/15K, Schneider XW Pro), commercial backup operators, and rack-density-conscious installers running multiple battery banks in confined utility rooms.

Key Specs to Look For

  • 3U server-rack form factor — stacks cleanly in standard 19-inch racks
  • 5.12 kWh per battery (100Ah × 51.2V nominal)
  • 30+ inverter brand compatibility — CAN/RS485 plug-and-play with major 48V inverters
  • OTA firmware updates — battery firmware improves over time without hardware swap
  • Parallel up to 16 batteries — scale to 80+ kWh in a single rack
  • 10-year warranty with rated 6,000+ cycles

Why Buy SOK From Urban Supply

  • Authorized SOK Battery dealer — every battery covered by full manufacturer warranty
  • Free shipping on orders over $299 (exclusions apply for LTL freight items)
  • Best price guarantee — find it lower, we'll price match
  • Flexible financing via Shop Pay Installments
  • 30-day return policy on unopened, undamaged batteries
  • 30-minute response time on all customer emails

Why Choose SOK LiFePO4

Server-rack 48V is the modern standard for whole-home and commercial solar storage. Higher voltage means lower current at the same kWh, which means thinner wiring, smaller breakers, and lower voltage drop — critical at 10+ kWh scale. SOK's open-protocol approach avoids the inverter-vendor lock-in that plagues some battery brands (no proprietary EG4-only or Sol-Ark-only batteries here).

Frequently Asked Questions

Which inverters does the SK48V100N work with?
EG4, Sol-Ark, Schneider Electric, Victron Energy, MidNite Solar, Outback, Magnum Energy, Growatt, Deye, Megarevo, Pylontech protocol clones, and many more. We confirm compatibility before every order.

Can I mix SOK with other 48V batteries on the same inverter?
Generally no. Mixing battery brands on a CAN-bus inverter creates BMS coordination issues. Stick with one brand per battery bank for clean SOC reporting.

Do I need a battery management system separate from the battery's BMS?
No — the SK48V100N has a built-in BMS with cell balancing, temperature management, over-current/over-voltage/short-circuit protection, and inverter communication. No external BMS required.
