## Inverter Sizing
### Formulas
**Inverter Rating = Continuous Load x Surge Multiplier**
**DC Current = AC Load / (DC Voltage x Efficiency)**
Motors and compressors draw 2-3x surge at startup. Size the inverter for the surge, not just continuous load.

Exemple Résolu
500 W continuous load, 2x surge, 90% efficient inverter on 12 V DC.
- Minimum inverter = 500 x 2 = 1000 W
- DC current = 500 / (12 x 0.9) = 46.3 A
- DC power = 500 / 0.9 = 556 W
