Quick Answer
The best solar generators for home backup offer 1000–2000Wh capacity, 1000W+ output, and reliable battery technology. Budget options work for short outages, while higher-end systems provide longer runtime and more flexibility.
What to Look for in a Solar Generator
Before choosing a model, focus on:
- Battery capacity (Wh) → determines runtime
- Output power (W) → determines what you can run
- Battery type → LiFePO4 preferred for longevity
- Expandability → ability to add extra batteries
