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.
Most installations slightly oversize the inverter, with a ratio between 1.1-1.25 times the array capacity, to account for these considerations. The size of the solar inverter you need is directly related to the output of your solar panel array. The inverter’s capacity should ideally match the DC rating of your solar panels in kilowatts (kW).
An important consideration in calculating inverter size is the solar panel system:inverter ratio. This is the direct current capacity of the solar array divided by the maximum alternating current output of the inverter. For example, a 3kW solar panel system with a 3kW inverter has an array-to-inverter ratio of 1.0.
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.
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.
Using three 12.6 kW string inverters in this 30 kW commercial solar PV system allows for modular expansion later. The inverters are perfectly sized at 1.25 times the array’s capacity. Improperly sizing the solar inverter can undermine the purpose of investing in an expensive PV system.
