This is a reading from the 2020 NEC of Article 705 Interconnected Power Production Sources, which features 705.11 Supply-Side Source Connections, 705.12 Load-Side Source Connections and the new in 2020 705.13 Power Control Systems (PCS). 705.13 is new and will be very useful for making interconnections, so that we are not limited by the options in 705.11 and 705.12. When we have very smart electronics coordinating the currents, such as with smart load centers, CTs and smart inverters, PCSs can make sure our busbars do not melt. Artificial Intelligence anyone?

For someone who is just learning about PV or energy storage and has no idea about the NEC, this might be overwhelming, or at least a way to get familiar with the terminology while falling to sleep. For those of you that are familiar with the NEC, dive into island mode!
