6 FAQs about [Photovoltaic inverter ratio selection table]

What is the array-to-inverter ratio of a solar panel system?

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. If you install the same-sized array with a 5000 inverter, the ratio is 1.2.

What is a good array-to-inverter ratio?

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

How do I choose the right solar inverter size?

The size of your solar array is the most crucial factor in determining the appropriate inverter size. The inverter’s capacity should match the DC rating of your solar panels as closely as possible. For instance, if you have a 5 kW solar array, you would typically need a 5 kW inverter. Array-to-Inverter Ratio

What ratio should a 5000 inverter have?

If you install the same-sized array with a 5000 inverter, the ratio is 1.2. Most installations will have a ratio between 1.15 to 1.25; inverter manufacturers and solar system designers typically do not recommend a ratio higher than 1.55. Below are some examples of solar inverter products and their maximum DC power output recommendation:

What size inverter for a 5 kW solar array?

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.

What is the output of a solar inverter?

The output of a solar inverter, a crucial metric in assessing the performance of a solar energy system, is derived from the conversion of direct current (DC) to alternating current (AC) power. This output can be evaluated in terms of power (expressed in kilowatts AC), or in terms of current (amps) and voltage (commonly set at 240v AC).
