Recall History: LG has had multiple battery recalls (fire risk) with mixed aftercare handling. Verify recall status before purchase.
Verify warranty support and local service availability before purchase.
LG Energy Solution, spun off from LG Chem in 2020, is one of the world's largest battery manufacturers, producing cells for electric vehicles, grid storage, and residential applications. The company's RESU (Residential Energy Storage Unit) series has been a popular choice for home battery installations worldwide.
The RESU series uses NMC (Nickel Manganese Cobalt) chemistry, offering high energy density in a compact form factor. The 48V RESU Prime series represents their latest residential offering, compatible with a wide range of hybrid inverters including SolarEdge and Fronius.
LG's manufacturing expertise from EV battery production translates to residential products, with consistent quality control and proven cell technology. However, the broader market shift toward LFP chemistry—which offers better thermal stability—has positioned NMC-based products differently in hot climates like Perth.
The company has faced some challenges including a 2020 recall affecting certain RESU models due to fire risk, which they addressed with a comprehensive remediation program. Current products incorporate improved safety features, though the recall history means buyers should verify model numbers and ensure compliance.
