Product detailed description

The LG RESU FLEX high-voltage battery is a modular system that serves as an electrical energy storage system suitable for both floor and wall installation. This battery is available in three different sizes with usable capacities ranging from 8.6 to 12.9 to 17.2 kWh, which can be expanded up to 34.4 kWh by connecting the two systems in parallel.

Specifically, this battery pack contains 2 to 4 battery modules with a capacity of 4,3 kWh (BMA), which can be expanded by the user as required. The RESU FLEX system is thus modular and can be easily expanded to a maximum of 4 battery units.

The control unit (BPU), marked with the LG symbol, is part of the battery pack and can be connected to a series of installed batteries. The battery is also compatible with hybrid inverters from Kostal, Fronius, SMA and GoodWe. This product is globally certified, and the BMA and BPU can also be obtained separately.

The main advantages of the product include:

  • Modular expandability - RESU FLEX is a modular energy storage unit that can be expanded up to 4 batteries.
  • Flexible installation - the battery can be easily adapted to different space requirements. More than 30 different installation configurations are available to maximize space efficiency.
  • Compatibility - RESU FLEX is compatible with monitoring and hybrid and battery inverters, allowing users to easily integrate with existing systems.
  • High Capacity - With storage capacities of 8.6 kWh, 12.9 kWh and 17.2 kWh, RESU FLEX provides enough capacity to meet the needs of most households.
  • Reliability - LG guarantees the reliability and longevity of the product, thus providing a 10-year residual value warranty.
