When it comes to solar inverter sizing, installers will consider three primary factors: the size of your solar array, geography, and site-specific conditions. The size of your solar array is the most important factor in determining the appropriate size for your solar inverter.
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.
Solar inverter sizing refers to choosing an inverter with the appropriate AC output for your solar panel system’s DC input. It’s about matching capacity and performance, without wasting energy or breaching local export limits. Inverter size is measured in kilowatts (kW). It should match your solar array within a 1.15 to 1.33 ratio.
Sometimes, installers might suggest a 3.6kW inverter even if your system requires a larger one. This often is to simplify the G98 application process, the standard grid connection procedure for small-scale solar systems in the UK. While a 3.6kW inverter can facilitate grid approval, it may not align with your actual energy needs.
The size of your solar inverter can be larger or smaller than the DC rating of your solar array, to a certain extent. The array-to-inverter ratio of a solar panel system is the DC rating of your solar array divided by the maximum AC output of your inverter. For example, if your array is 6 kW with a 6000 W inverter, the array-to-inverter ratio is 1.
Inverters are usually sized lower than the kilowatt peak (kWp) of the solar array because solar panels rarely achieve peak power. The solar array-to-inverter ratio is calculated by dividing the direct current (DC) capacity of the solar array by the inverter's maximum alternating current (AC) output.
