GRID-TIED INVERTER SIZING

Calculate the System Size (AC Watts) to Provide 100% of Your Electricity

• Divide your daily average electricity use by the average sun hours per day.
  • For example, if the daily average electricity use is 30kWh, and the site is in NC, then the system size would be:
    
    30 kWh / 4.5 h = 6.6 kW AC
