Pylontech Force L2 48V 14.21kWh Managed Battery System (4 Cassettes + BMS Controller and Base)

The Force-L1 & L2 are a 48V DC modular stackable Energy storage system based on the lithium iron phosphate battery technologies. Its attractive Furniture type design and IP55 Rating makes it ideally suited for installing as a home energy storage system.

The Force L1 & L2 battery systems is designed to be installed without the aid of the inter connection battery cables, significantly reducing the installation time. The basic module is 3.55 kWh cassette, with a 90% DOD, and is available in two shapes, the L1 wider and lower or L2 narrower and higher, to meet all space requirements.

Features & Benefits:

  • Modular design from 7.1kWh to 24.86kWh enables quick and secure installation, & maintenance with no exposed wiring or connectors
  • Up to 6 stacks of Force L2 can be linked using the included M19-RJ45 Cable Kit to further increase Capacity to 149.16 kWh
  • Multiple stacks can be paralleled to increase current output for larger inverters
  • Cycle life: >6000 cycles @ 25°C with 90% DoD for daily cyclic applications
  • Working Temperature Range -10°C to 50°C, (Charging 0~50°C: Discharging 10~50°C) with excellent discharge performance & cycle life
  • The solar battery is suitable for indoor and outdoor (IP55) installation
  • Cathode material is made from LiFePO4 for safety performance and long cycle life
  • The BMS has protection functions including over discharge, over charge, over current and high/low temperature
  • Compatible with many available Hybrid inverters
  • Safety Cert. CE,TüV, UL, RoHS, UN38.3, IEC62619, IEC62040, IEC62477, IEC61000-6-2,IEC61000-3
  • Clean Energy Council Approved (CEC)


Warranty: The Force-L1 & L2 comes with a standard warranty of 10 years. Register your product on the Pylontech website. A linear depreciation to a minimum of 80% of capacity over 10 years is expected and is not covered by the warranty.
