The need for an inverter size chart first became apparent when researching our DIY solar generator build. Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly.
To account for power losses assume an 80 percent efficiency. Your solar inverter should have a similar or slightly higher wattage rating than the DC output of your solar panels (which in this case is 4.5 kW). You can size it between 1.15 and 1.5 times larger. The rule of thumb is to size your inverter 1.25 bigger than your solar array.
Oversizing or having an inverter that is too big for your solar panels will not produce enough electricity. Undersizing or having an inverter that’s too small will convert a limited amount of energy. You can avoid both of these scenarios by following these three basic steps to solar inverter sizing.
Ready to size your inverter? Follow this proven process: Calculate your total panel capacity Count your panels and multiply by their wattage rating. Example: 20 panels × 400 watts = 8,000 watts (8kW) Apply the DC-to-AC ratio Divide your array capacity by your target ratio.
