I believe midnite still has the remote trip DC PNL mount breakers, but of course, no birdhouse to make it work. Not sure what the trip trigger needs either as far as voltage.

The AHJ has said they will require a remote battery disconnect. I suspect there will be fire sprinkler controls and a pressure pump that would become inoperable if this system were engaged. In this case we will apply for a waiver. The last time this was discussed here as far as I can find was October of 2020. At that time no one suggested any specific battery disconnect equipment. To further clarify my needs: There will be 4 or 5 Radian 8048 inverters (5 or 6 4/0 battery circuits, ~350A each) and two 175 amp PV recombiner outputs. That is 6 poles of high amperage DC disconnects. The battery array will be either a UnigyII VRLA or a lithium of a brand yet to be determined. In the case of lithium we will look for a system that can remotely enable a BMS shutdown. In the case of a VRLA lead-acid, we will not have that luxury. I have done some considerable research and have not found viable, high amperage, remotely activated shutdown equipment. I am wondering what hardware others may be using to achieve remote battery disconnecting in these types of cases..
