Expert Instructor Ryan Mayfield on three student questions regarding Megawatt Design equipment and software selection
1. String inverters & AFCI failures…
Student 1: I have seen many people staying with central inverters on big jobs mostly due to AFCI failures. I think the AFCI issues are being resolved, but it burned […]
One of the most important aspects of designing a solar array is sizing module strings to operate within the parameters of the selected inverter. This is especially true for commercial and megawatt solar projects.
To help in this process, we’re providing a free solar design tool to our readers.
