FAQs 6

How do you calculate a string size for an inverter?

Calculate the Maximum String Size 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.

How many strings can a solar inverter handle?

Each string though can only be up to 5,250W even though the inverter can handle up to 12,400W (or 14,250 for the next size up inverter). I was told by SolarEdge that if you want to fed more power into the inverter, say the maximum 12,400, then you need to three strings and combine the strings using a combiner box.

How many inputs does a string inverter have?

The inverter (appropriately called a string inverter) has three string inputs. This system is designed to connect three strings of 8 panels each into those inputs (totaling 24 panels). Why Does String Sizing Matter? Inverters operate within a specific input voltage range, called the operating range.

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.

How to size a solar power inverter?

During the inverter sizing you need to take into account the different configuration limits, which should be considered when sizing the solar power inverter (Data from the inverter and solar panel data sheets). During the sizing, the temperature coefficient is an important factor.

How many volts is a string inverter?

String voltage = 37.6V * 19 panels = 714.4V This is higher than the inverter’s minimum DC input voltage (200V), so it’s fine. The total string current is the same as the Isc of one panel, 9.4A, which does not exceed the inverter’s maximum DC input current (25A).
