|---|---|---|---|
| 1,000W | 1,000W | 2,000W | Small loads |
| 2,000W | 2,000W | 4,000W | Basic backup |
| 3,000W | 3,000W | 6,000W | Small home |
| 5,000W | 5,000W | 10,000W | Medium home |
| 8,000W | 8,000W | 16,000W | Large home |
| 10,000W | 10,000W | 20,000W | Whole house |
Inverter Types
Pure Sine Wave
Best for all equipment. Required for sensitive electronics, motors, and medical equipment. Higher efficiency.
Modified Sine Wave
Lower cost option. Suitable for basic resistive loads. May cause buzzing in motors and not work with some electronics.
