Key item features

  • Designed for Stationary Use. Unlike portable GenBox models, the 1200S “Slim” is engineered to stay in place—wall-mounted or on a floor stand near your refrigerator, freezer, or other essential appliances. Always plugged in, always ready, automatically protecting your home 24/7
  • Instant UPS Protection. Built-in UPS functionality with sub-20ms switchover time. When the grid fails, the GenBox 1200S instantly switches to battery power—your refrigerator, freezer, or medical equipment never stops running. No manual intervention required. Set it and forget it.
  • Longest-Lasting Battery. 1,382Wh LiFePO4 battery rated for 5,000 cycles to 70% capacity—the longest lifespan of any GenBox model. That’s ~13+ years of daily cycling or decades of backup use.
  • Expandable to 5.5kWh. Stack up to 3 additional battery modules (GenBox-1.3B Expansion Battery) to increase total system capacity up to 5.52kWh.
  • Multiple Deployment Strategy. Use multiple GenBox 1200S units in different areas—one for your refrigerator, one for your freezer, one for medical equipment, one for home office.
  • Pure Sine Wave & Smart Management. 1200W pure sine wave output safe for all appliances and sensitive electronics.
