In This Episode:

  • RAPID ROUNDUP (00:37): A&K talk us through recent articles in PV Magazine and Solar Builder Magazine on upstream materials (e.g. wafers); perovskite; NEC mandates on locking disconnects.
  • DEEP DIVE 1 (4:30): A&K check in with Devon Wilson from BYD to discuss their growing footprint in the U.S. residential batteries market.
    • Devon provides an overview of BYD’s B-Box HV, a lithium iron phosphate (LFP) battery that’s stackable and flexible to design options while boasting true high-voltage output and ease of installation.
    • The gang discusses the advantages of LFP batteries over NMC batteries for residential use; excitement over BYD’s upcoming B-Box HVL line and its design story and safety advances; and the SGIP timeline updates for the new product.
  • DEEP DIVE 2 (27:00): A&K visit with Matt Paiss of the U.S. Department of Energy’s Pacific Northwest National Laboratory (PNNL) to understand the certification and testing landscape for battery manufacturers. A former fire captain, Paiss was a Solar Town Hall guest speaker on our codes and compliance episode last summer. Here, he chats with A&K about
    • How residential installers and system designers can anticipate inspection and testing requirements surrounding the fire code and storage systems
    • UL 9540 versus UL 9540A testing methods and thermal runaway worst-case scenarios
    • The chemical science nuances of thermal runaways and other battery-related hazards
    • Ground-mount versus wall-mount safety testing
    • And ongoing research on explosion prevention in cabinet-based systems.
  • BIG IDEAS (49:30): A&K showcase their fantastic new tool for solar contractors who purchase from BayWa r.e. Solar Systems — a Storage Comparison Doc of leading energy storage products summarizing their relative performance numbers side-by-side in one single PDF.
    • These comparisons tell us how much energy will be accessible to the homeowner when using a battery-inverter system for home energy storage — and of that energy, how quickly can it be discharged for use.
    • Click here to download the doc and start using it to develop your designs, and boost customer and leads engagement!
