How to calculate inverter load percentage
This calculator finds inverter load percentage by dividing connected load by inverter rating — checking whether an inverter has adequate capacity for the load it's serving.
How the calculation works
Load percentage = (Connected load ÷ Inverter rating) × 100.
Example
800W connected load on a 1,500W inverter: Load percentage = (800 ÷ 1,500) × 100 ≈ 53%.

Pro Tips for Inverter Load Percentage
- Leave headroom below 100% rated capacity, since many inverters shouldn't be run continuously at their absolute maximum rating.
- Account for a load's startup surge (like a motor or compressor) which can briefly draw much more than its steady-state running wattage — check the inverter's surge rating separately.
Common Inverter Load Percentage Mistakes to Avoid
- Sizing an inverter based only on steady-state running wattage without checking startup surge requirements for motor-driven loads.
