Solid State Relay for Hot Tub load Shedding?

Greetings, I am looking for some advice that is way out of my wheelhouse. I am trying to create a load shedding controller for my home that will drop non-critical loads when the grid drops (hot tub, heat pumps, etc). I have a PV + ESS system and am looking at these home load controllers https://knowledge-center.solaredge.com/sites/kc/files/se-home-load-controller-datasheet-nam.pdf

What I am hoping to use is a solid state relay instead of mechanical contactors. Can anyone please tell me if a SSR rated for 120VAC input and 240VAC 50A output exists (for hot tub)? Would a DPST work if the exist? Appreciate any help!!

Yes, they exist. Here is a sampling from Digi-Key. Most industrial distributors will have something like it.

I see now that you are looking for a double-pole SSR. These are far less common, but they're out there somewhere.

Thanks. I guess the question is if a DP relay is required? My lack of electronics controls just led me to think that I would need to control each 120V leg of the circuit, but that's why I came here for more educated replies. If DP is needed does it need to be DPDT or DPST would be ok?

It would be a new controller. No replacement of contactors, but if I were to use one it would be a 250VAC 2 pole contactor. Is that what you are asking? Thx
