You need to better describe your system and goals. Is this grid tied or stand alone? You imply that it has a battery - true?
What are you trying to accomplish, and what interaction are you expecting between the two high power loads you mentioned and the PV system? I would certainly not expect any smarts on the part of the toaster over - it's simply going to expect a steady supply of 120 volt AC power at whatever current it is drawing. Likely the same with the EVSE - except I assume it is expecting 240 volts.

As we search for ways to manage the load for the system we are curious as to what AC loads we can use. Here are two examples that have raised questions: 1.) Grizzly 8Kw EVSE 2.) Cuisinart toaster oven We have charged EVs here at J&R housing since 2010 with no problems using ClipperCreek EVSE as a service and for our 2018 Tesla. Recently we installed an OutBack 3 Kw PV system and then a 8 Kw Grizzly EVSE as a load to charge our 2018 Tesla. The system works, but the Grizzly system does not interact with the OutBack system in a convenient way. As an aside, we derated the 48A to 24A with a 30A breaker. We are pleasantly surprised that a 5A feed setting adds up as clouds come and go to manage power through the OutBack PV/Grid/48V battery system. It all works well. The system works. My question is about convenience, sharing and curiosity. The folks at Grizzly could not help me and I did not contact OutBack but I am guessing that the electronics of the two systems conflict in such a way that I have to manually use the Grizzly by switching it at the breaker and or on occasion (briefly)add as needed, a heater load to the OutBack service to get the Grizzly to function as I watch its status by a series of displayed colored lights. I wonder about the PV controller/48V battery/sun-cloud feed to the inverter. The electronics of the Cuisinart Toaster Oven also raises questions about the OutBack AC output. Spikes/more data/forget it? Good old DC loads? As a retired physics teacher who understands much of the electricity of Classical Physics and wonders about the uncertainty and relativity of Modern Physics, I cannot help but wonder if the issue I have encountered with my EV/PV/EVSE is of interested to anyone or has a practical solution. Since I took advantage of their sale price I have a second Grizzly unit to swap out but I was not encouraged to do that by the Grizzly engineers.
