To calculate the ideal inverter size for your solar PV system, you should consider the total wattage of your solar panels and the specific conditions of your installation site. The general rule is to ensure the inverter’s maximum capacity closely matches or slightly exceeds the solar panel array’s peak power output.
For example, a 5 kW solar array typically requires a 5 kW inverter. However, factors like derating, future expansion plans, and the array-to-inverter ratio influence the optimal inverter size. Most installations slightly oversize the inverter, with a ratio between 1.1-1.25 times the array capacity, to account for these considerations.
Installers typically follow one of three common solar inverter sizing ratios: For our example 7 KW system, this translates to inverter sizes between 8,750 watts and 9,450 watts. While the above wattage rules apply to a majority of installations, also consider the following factors before deciding the sizing ratio.
Correct sizing of a solar inverter is crucial. The wrong inverter capacity will weaken the performance of the solar panel system. The inverter has to be able to deal with the amount of energy it’s getting from the panels. Inverter sizes are measured in watts (W) or kilowatts (kW) – units of a thousand watts – the same as solar panels.
Under the Clean Energy Council rules for accredited installers, the solar panel capacity can only exceed the inverter capacity by 33%. That means for a typical 5kW inverter you can go up to a maximum of 6.6kW of solar panel output within the rules.
Inverters come in different sizes starting from as little as 125 watts. The typical inverter sizes used for residential and commercial applications are between 1 and 10kW with 3 and 5kW sizes being the most common. With such an array of options, how do you find the right size for you? An inverter works best when close to its capacity.
