![]() ![]() ![]() In this range, your inverter will turn on and deliver power to your appliances. ![]() The operating range is simply the range in which your inverter will properly function. This system is designed to connect three strings of 8 panels each into those inputs (totaling 24 panels). The inverter (appropriately called a string inverter) has three string inputs. String sizing describes the calculations we make to determine how many panels we should plug into one input for optimal efficiency.Ī panel string is a group of panels wired into a single input on your inverter.įor example, this grid-tied system contains 24 Mission Solar 360W panels and one SMA Sunny Boy 7700W inverter. Our goal is to equip you with accurate information to make informed decisions during your research and design process.Ī panel string is a group of panels that are wired into a single input on your power inverter. However, we know that many of our readers are heavily inclined toward the DIY approach. It’s worth noting that the grid-tied and off-grid systems we sell already take string sizing into account, so you won’t have to worry about this if you work with one of our designers. I wanted to write this article to explain the concept of string sizing, and break down the string sizing calculations we do to ensure your panel strings are the proper size to keep you running at maximum efficiency. One common point of confusion is the concept of string sizing-how many panels you can wire into a single input on your inverter. We’ve written guides on how to size a grid-tied system, as well as sizing a battery bank for off-grid systems, which give you a pretty good idea of how much solar energy you need to produce to offset your energy consumption.īut they don’t dive too deep into more complex sizing concepts, like picking compatible parts for your system and wiring the components together properly.
