What is LG Chem RESU?
LG’s lithium ion RESU battery is a home energy storage solution that can be paired with a solar panel system. The RESU can be used both to maximize consumption of solar energy at home, rather than sending it back to the grid, and also functions as a source of backup power in the event that the grid goes down. However, while the RESU has some backup power capabilities, it isn’t designed for off-grid use. The LG Chem RESU comes in a range of sizes from 2.9 kilowatt-hours (kWh) to 12.4 kWh. The only LG battery currently for sale in the U.S. is the RESU10H, which has a usable capacity of 9.3 kWh. U.S.
