Midnite Solar surge protection device 120 subpanel

[JJJJ]

I am planning on adding a SPD to the 120 v subpanel going to the inverter from the grid.

When I asked the vendor for wiring specs they recommended: "Green goes to ground, Black to hot, Red to Neutral".

I have included a photo of the subpanel in question. Is he saying to apply to the input side?

It can be placed anywhere in the circuit. But should be after some sort of short protection. (Breaker or fuse)

Please accept my apologies in advance if this question seems too basic.

If I understand correctly would I connect on the bottom of the breaker and the neutral bus bar?

I think that breaker is made for 2 wires. (If it has a central screw with a squared washer.)
If so, then yes that's fine.

Sorry for the crappy photo, you can see mine installed in a standard panel.
Yours would be the same except red to N.

Actually when I zoomed in the quality was quite good. Thank you very much!
