Energy storage and backup for businesses
KSTAR energy storage systems of 215 kWh and 261 kWh, with a 125 kW hybrid inverter. See batteries for businesses: industrial halls, farms, factories.
If large motors start up in the hall, backup is sized separately: at start-up, a motor can draw several times its rated power. Details in the article Battery Backup for Industrial Halls: Why Motors Change the Calculation.
