Best Generators for Home Backup in 2026
The best generators for home backup in 2026, from portable inverter units for essentials to automatic standby generators with ATS for whole-home protection.

Quick Answer
For home backup, a 6-8kVA portable inverter or diesel generator covers essentials (fridge, lights, TV). For automatic whole-home backup, an 11-14kVA standby generator with an auto-transfer switch (ATS) starts within seconds of a power outage. The Hyundai DHY9KSEM 11kVA is a top standby pick.
Best Generators for Home Backup in 2026
When the grid fails, a home backup generator keeps your fridge, lights, heating and essential circuits running. The right choice depends on whether you want portable manual backup or automatic standby power.
Two Types of Home Backup
Portable Backup (Manual)
A portable generator you wheel out, start manually and run extension cords to essential appliances. Cheaper upfront, but requires you to be home and to manually start and connect it.
Standby Backup (Automatic)
A permanently installed generator with an auto-transfer switch (ATS) that starts automatically within seconds of a power outage. More expensive, but fully hands-off — it works even when you're not home.
