Nope. You are a master electrician and are fully qualified to string wires in houses and comment on wires, It's unlikely you are an ELECTRONICS engineer and understand inherent safety, UL requirements that a device be able to take a 200% overload for some specific time and not cause a fire.
You should know if a house fire is traced to a non-UL appliance, the homeowners fire policy is voided and it's likely any responding agencies will send a bill for rendering services, And you better hope there are no injuries related to the incident (fireman having a heart attack......)
Many reports indicate most of the plug-in inverters only last a year or so before the dubious quality parts inside fail. Also, many are fairly low efficiency (80-90%) whereas most approved ones are >95% efficient.
Along with the simple plug-in install, it's likely the PV panels will not be robustly installed either. But that's not your electrical problem.
So I will say they CAN be nifty devices, and if they were able to be reliably installed (by the time you wire up a dedicated circuit, why not go with a approved system), there is really no reliable way to track the vendors and distributors hiding behind virtual storefronts. Making the devices legit, UL certified, brings the cost up to the same level as the enphase modules. And then there is the reliability issue with cheap electronics baked and frozen on a roof
