Everything Solar Forum

This week we take a look at grid defection - are technology, utility policies, and economics at the point where it just does not make sense to stay connected to the grid? Each Tuesday at noon (Eastern) solarPVtraining.com hosts a Zoom sessions for students (or anyone, really) interested in solar. Generally discussion focuses on technical questions, problems or troubleshooting - or just what is happening in solar that week.

Listen to it after the fact. Over all pretty good. I have one bone to pick. Near the end when you were talking about over sold transformers in your 10 houses on one 50KW transformer, you added to the load on the transformer for the producers when producing. That is wrong. If you have multiple houses (meters) on one transformer, they are connected in parallel to the SECONDARY!! Not the primary. In short the over production services directly to the load of the non producers which actually reduces the load on the transformer, not increasing it. I have this situation on my installed 50KW trans that I had put in when I ran my power feed underground. I have 3 houses on my trans (Including me). When I am producing, my overproduction goes directly to my neighbors meters, never making it to the primary side. Thus reducing the load on the trans. The only way production from multiple houses becomes load is when all production exceeds all load combined, then it crosses over from the secondary to the primary, as production load. In short they are NEVER additive....
