I go through the rationale of how to wire a bigger solar electric pv photovoltaic system on a house. We have 30 Yingli solar modules (275 watts each) on this house in Carbondale, CO for a total of 8250 watts, 8.25 Kilowatts, KW. Multiple strings are required, I go over why you need to divide the panels up into strings, along with some math. A Sunnyboy SMA inverter was installed on this house. I also go over how to wire a production meter, different utilities require different wiring configurations in regards to line and load. In addition, I go over some of the labels that required by the NEC code. Check out my other videos for smaller systems, questions are welcome.
Here’s a previous video were I install 1.47 KW with an Enphase microinverters.
I explain how much this system cost and I go over the site plan and electrical diagram in this link
Here’s a bigger system at 44 KW that I installed on top of a commercial building.
