Here in MN we're about to jump into 2020 and I'm trying to plan on the best way to implement the new SPD requirements for dwelling services, 230.67. A lot of times we will only have a knife-blade fused disconnect for our service and an inverter. I'm not sure of the best way to install a SPD in this scenario. We also use Enphase's IQ combiner which will allow a plug on SPD if we have space. One thing I thought might work was to splice a Type 1 SPD on the load side of our disconnects since they are rated to be installed on the line side of OCP. Any other ideas?

Well, you could also try arguing that it's not a service disconnect. 
Seriously, I think your ideas are fine.
