Energy Storage is what everyone is talking about, so this year for their SPI workshop, Bill and Sean will present both Energy Storage System (ESS) and PV topics, however, will emphasize ESS more than in the past, yet still include PV, interconnections, bidirectional EV charging and more exciting updates.
Here are a few topics we will cover: • Implications of the new UL 3741 listing for rapid shutdown, which can let us put 3 60 cell PV modules in series in certain instances. • New NEC 705.13 Power Control Systems, which can be a work around for the limitations of load side connections in 705.12. • 690.8(A)(2) Circuits Connected to the Input of Electric Power Converters, which allows us to use the maximum input current of an inverter rather than the current of the PV for sizing wires and equipment. • When to use NEC 706 and not 480 for ESS. • Making sense of the different UL listings for ESS.
This workshop will cover the 2020 and 2017 NEC, pointing out the differences.
