| Perfect comment on the topic. With that said, newer inverters do have “grid fault ride through” capabilities where they will continue to operate during excursions from nominal operating windows, and some regulators are more hip to it than others. https://www.iso-ne.com/static-assets/documents/committees/co... https://www.solarpowerworldonline.com/2019/03/smart-inverter... Grid forming inverters (versus the traditional grid following) are at the finish line of being proven, and paired with distributed storage providing ancillary services (including frequency response), regulators simply need to be dragged to the present to solve for this (distributed energy orchestration, rapid system segment isolation and recovery during transient events [“self healing” for the marketing folks], etc). This is one of those tug of wars between very conservative regulators and a quickly innovating industry (DER power controls). https://www.energy.gov/eere/solar/articles/powering-grid-for... https://www.nrel.gov/news/features/2020/renewables-rescue-st... https://www.nrel.gov/docs/fy21osti/73476.pdf https://www.eia.gov/todayinenergy/detail.php?id=50176 |
During sun, a site can island with perfect 60Hz AC power from the ASIC-driven IQ8. No battery –– and certainly no grid –– needed.
