LG Chem’s range of battery storage banks in Australia

LG Chem is one of the clear leaders in Australia’s burgeoning home battery storage market. The company’s RESU lithium battery made a big splash when it was introduced last year as an affordable, high-quality competitor with Telsa’s much vaunted Powerwall. LG Chem has not rested on its laurels, however, having already introduced the next generation of lithium battery banks with a sleeker appearance and more flexible sizing options.

All of the batteries banks in the RESU range come with a 10 year performance warranty. ‘End of life‘ retained capacity is 60% of the original nominal capacity – meaning that by the end of 10 years you should expect the battery to be able to store no less than 60% of of what it did at the beginning of its life. Another common feature of all of the batteries is a cycle life of 6,000 cycles, which effectively means that they can be charged/discharged more than once per day to take advantage of ‘tariff arbitrage‘ benefits possible with a time-of-use billing structure. All units may be installed either indoors (wall-mounted) or outdoors.

RESU features:

  • High quality home battery banks from a company whose parent is a highly diversified industry giant
  • A range of sizes means it’s easy to mix, match and stack units to suit energy requirements & budgets
  • Compatible with a range of popular inverters
  • Can be installed indoors and out
  • Aesthetically pleasing design, available in silver and gold colour options
