Next I did the same thing with High Sierra, and I'm getting the message:
"macOS could not be installed on your computer. An error occurred while verifying firmware. Quit the installer to restart your computer and try again."
Unfortunately Apple is not clear here as usual. Either the firmware contained within the installer is corrupt, or the firmware updater had a problem verifying the firmware update on the laptop after it was "upgraded". I suspect it is the former issue, but I am not certain.
Are you just running the HS installer from within macOS? Have you tried to create a bootable macOS USB drive and install from the USB installer? If you are using a USB installer, then try using a different brand of USB stick since the quality of USB sticks is quite poor. Here are the instructions for creating a bootable macOS USB installer:

There is always a possibility that the SSD you purchased is defective or perhaps it is not actually the exact model for this particular laptop. I've never ordered parts from Beetstech before, but their website, information and documentation seem quite good, but there is always a chance they made a mistake on the exact model of this SSD.
Any ideas? Why can't Apple just provide a firmware update package separately? Just about everyone else I deal with does (Dell, Cisco, HP, etc.). BTW, the SSD was in a sealed anti-static package:
Even when Apple provided individual firmware updates there were issues since they required a very specific version of macOS to use them. I tried to update the firmware on some older Macs before that had later versions of macOS and those firmware installers always complained about using an incorrect version of macOS. Apple expects things to be done a certain way and never thinks about what happens if something prevents things from happening in the order Apple expects. Apple thought putting the firmware updaters into the macOS installers was a safer option, but unfortunately there are issues with this approach as well as you are experiencing plus I've heard reports that some systems don't get the updated firmware like they are supposed to do.
I agree it would be nice to have an OS independent system firmware updater option available like Dell and other OEMs use. You can always provide product feedback to Apple here:
