Free QuoteThe 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. If you install the same-sized array with a 5000 inverter, the ratio is 1.2.
Before selecting an appropriate inverter size, there are several key factors to consider, including the total system size (DC wattage of all solar panels), expected energy consumption (daily and peak usage in kW), future expansion plans, local climate, and solar irradiance levels. System Size (Total DC Wattage of Solar Panels)
Because the PV array rarely produces power to its STC capacity, it is common practice and often economically advantageous to size the inverter to be less than the PV array. This ratio of PV to inverter power is measured as the DC/AC ratio. A healthy design will typically have a DC/AC ratio of 1.25.
The maximum recommended array-to-inverter ratio is around 1.5-1.55. Oversizing the inverter too much can lead to increased costs and inefficiencies, while under sizing can result in clipping, which is when the inverter can't handle the peak power output from the solar panels, leading to energy losses. Solar Array Size
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.
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.
