String Sizing Tool Quickstart

It’s important to understand string sizing methods and what is allowed according to the code. If you want to learn how to do this manually, please read and follow this String Sizing Article to learn more about what this tool is doing in the background. The String Sizing Tool will take input from the inverter or Solar Charger, temperature, and module information, and output string sizing results that are within the converter’s limits.

We have an inverter/solar charge database that includes Fronius, OutBack Power, SMA, SolArk, Victron and more! We have a solar module database that includes Jinko Solar, LG NeON, Q.Peak, Trina Solar, ZNSHINE Solar and more! Feel free to contact me to add an inverter or solar module to the database.

Watch this quickstart video to learn how to string size.

Enjoy the full database !
