Marco - The Sunny Boy Storage "Advanced Backup Unit" accessory or ABU will be discussed at SPI in a couple weeks - first units are being stocked now at our warehouses in US. The ABU will allow the SBS to be a grid former in case of utility outage, however there are no plans to have any generator inputs/controls to allow for battery charging from generator.
And yes, BYD BBox HV 5.12/7.68/10.24 devices will be supported when available in US (will be this year I understand) Mike ----- The SMA Sunny Storage looks promising. It will be able to work with the LGC RESU10 HV battery and, sooner rather than later I hope, BYD package as well. And it will allow for a backup generator tie in.
