The SOK 48V Server-Rack Battery:

SOK is taking the 48V battery world by storm with an extremely convenient & modular server rack design. When incorporated into a datacenter, telecom room, or a whole home backup system, you can fit some serious capacity into a minimal amount of space. The capacity of each module is 5.12 kWh – this means that this system with 5 batteries can easily power heavy loads for hours!

Features:

  • Equipped with 5 temperature sensors to safeguard against extreme temperatures.
  • Features a pre-charge circuit to prevent any potential damage to the Battery Management System (BMS).
  • Supports RS485 and CANBus communication protocols, ensuring compatibility with a wide range of inverters. (Be sure to select the proper communications cables.)
  • Designed for rack mounting, facilitating swift and effortless setup.
  • Enjoy a comprehensive 10-year full warranty and a typical lifespan of 20 years.
  • Cells rated for 80% capacity retention after 4000 cycles, even at a 100% Depth of Discharge (DOD) with a 1C rate.
  • Typical capacity at 80% Depth of Discharge (DOD) with a 0.5C rate surpasses 7000 cycles.
  • Certification in Progress – UL9540 pending for added assurance of quality and safety.

Why Choose SOK?

All products have an estimated useful life, the amount of time that a product is expected to stay in working order, which can vary slightly depending on the usage, environment, and build quality. Failures can also be caused by shipping damage, installer error, downstream equipment malfunction, natural aging, and unavoidable environmental factors such as lightning.

Competing 48V server rack battery manufacturers are not designing their products to handle a failure taking place. Other batteries on the market prevent user-serviceability and are permanently sealed using techniques such as IR-Laser Welding of aluminum cell-interconnection busbars, plastic injection-molded cases, and permanent epoxy potting during assembly. These processes are great for single-use disposable products, but a poor choice for systems expected to last decades. When parts within these permanently assembled packs fail, the entire module is rendered useless and needs to be disposed of as E-waste and replaced as a complete unit. Any attempt to service would certainly void your warranty and the likelihood of a successful service is slim to none.

This is where SOK has distinguished themselves as the leading battery manufacturer. SOK Battery believes that their batteries are an investment and should withstand the test of time. Instead of becoming expensive and toxic waste, the SOK Battery SK48V100 is engineered so that every single part within the battery pack can be field serviced using just a Phillips screwdriver and a 10mm wrench. Each component inside the battery's casing can be easily replaced by either an authorized service agent or the end customer, offering a convenient solution for those who prioritize battery maintenance and reliability. This means less downtime and lower repair costs to the end-customer, as well as a decreased environmental impact.
