SMA Secure Power Supply - What Appliances Does It Actually "Back-Up"

I've been doing a bit of research into the SMA Secure Power Supply and wanted to learn more from folks who have installed it. I like that it provides a plug for back-up, though I'm skeptical as to what appliances can actually be run off of that plug at 1.5kW.
My understanding is that it can power a laptop, home internet, or cell charger. And that it CANNOT power a fridge (not even a mini-fridge).
Has anyone tried to power a fridge (either normal fridge, or a mini-fridge) from the SPS? If so, does it work? Would be appreciative if others could provide some perspective here.

I do not think it would start his 28 Enterprise class reefer or would I want to rely on this, but it is pretty nice as a feature.

Also with good sun the inverters will put out the 1500W (not one watt more). I tested the SPS initially with oil space heaters up to 1500W. You need to keep it just below 1500W.
SolarEdge marketed their new HD Wave inverter with this feature as an option. Unfortunately, when they started to ship the HD inverters, that option was not available and I question if it will ever be. Vaporware !
I hope SMA will continue to innovate and make their new inverters with great features like SPS integrated DC disconnects and WiFi. I attended a presentation today about their new Power+ products which provide selective module level optimization (if you have just a few panels getting shading) or full deployment to use Tigo's Cloud Connected Advanced monitoring and rapid shutdown alternative. I was not impressed. This new product is not compatible with Secure Power Supply because it requires AC power! Their rapid shutdown solutions are expensive, time consuming and inconvenient. It is all getting too complicated, with too many parts to set up and install.
