waves 1. Pure vs Modified Sine Wave
Pure Sine Wave (PSW)

Modified Sine Wave (MSW)
warningProduces a stepped, blocky waveform. Cheaper, but causes excess heat and can damage sensitive electronics or compressors.
| Parameter | Pure Sine Wave | Modified Sine Wave |
|---|---|---|
| Appliance Compatibility | 100% (Universal) | Limited (Resistive loads only) |
| Audio/Visual Noise | None / Clean | High (Humming/Static) |
| Efficiency | High (~90-95%) | Lower (Excess heat loss) |

Calculating your required inverter capacity requires analyzing continuous load versus peak surge load.
The Calculation Protocol
Always account for motor startup surges. An induction cooktop drawing 1500W may peak at 2500W for milliseconds.
