FAQs 6

How many panels can an inverter have in a string?

Take your inverter’s maximum DC input voltage. Divide it by your adjusted Voc. This gives you the maximum number of panels you can have in a string. For instance, if your inverter’s max input is 1000V: You can’t have a part of a panel, so round down to the nearest whole panel. In this case, you could have up to 22 panels in a string. 4.

What is a solar panel & a string?

A solar panel, or we can say a PV module, is made up of several cells, where multiple solar panels are wired in a series or parallel. The design is known as a solar array. A string consists of solar panels that are wired in a series set to one input on a solar string inverter.

What is a string inverter?

A panel string is a group of panels wired into a single input on your inverter. For example, this grid-tied system contains 24 Mission Solar 360W panels and one SMA Sunny Boy 7700W inverter. The inverter (appropriately called a string inverter) has three string inputs.

How many solar panels are in a solar string?

So, based on these calculations, for this specific scenario, you could have a solar string of 19 panels. There are online calculators available for string sizing, such as the one found at AltEstore. These calculators can make it easier and more accurate to determine the appropriate string size for your specific set of conditions.

What is the maximum input voltage of a solar panel inverter?

The maximum input voltage of a solar panel inverter determines how you should set up your solar panels. Here’s an example: If an inverter has a maximum input voltage of 600V and each panel produces 40V, you could connect up to 15 panels in series (15 x 40V = 600V).

How many inputs does a string inverter have?
