Solid State Relay for Hot Tub load Shedding?

[Battman]

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?

What is the contact configuration of the contactor you are trying to replace?

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
