Inverter Sizing Calculator
How to use this calculator: Enter your solar array capacity and load requirements to determine optimal inverter size.
Free QuoteA 4.5 kW array (or ten 450-watt solar panels) would just about cover your consumption. The type of solar panels you choose can also impact the size of the inverter you need. Different types of solar panels have different wattage ratings and efficiency levels. The three main types of solar panels are monocrystalline, polycrystalline, and thin film.
System Size (Total DC Wattage of Solar Panels) The first step in inverter sizing is to determine the total DC wattage of all the solar panels in your system. This information is typically provided by the manufacturer and can be found on the panel's datasheet.

Expected Energy Consumption Consider your household's daily and peak energy consumption to ensure that the inverter can handle the load.
Depending on where they fall in that band and the size of their solar array, they will likely use a 3, 5, or 10kW inverter. You also need to consider surge watts and voltage drop. Surge watts are the extra power required to start appliances that have motors, such as refrigerators and air conditioners.

Sizing Rule: Your inverter''s peak capacity must exceed the highest surge demand. Example: If your total running load is 500 W but your AC needs 2,400 W surge, choose an inverter with ≥ 2,500 W peak.
