How to select the Right Inverter Rating?
1. Calculate the Total Connected Load
2. Apply a Safety Margin
Total Load = 370 × 1.25 = 462.5 W
3. Calculate the Inverter VA Rating
Assuming an inverter power factor of 0.8:
Inverter Rating = 462.5 / 0.8 = 578.1 VA
Recommended Selection: 600 VA minimum based on the calculated load. Consider a higher-rated inverter after checking motor starting surge, battery voltage and manufacturer specifications.
