SPDT switch > 20A @ 32VDC?
I'm seeing SPDT toggles that are 20A at 125VAC Ebay 20A 125VACand some that are simultaneously rated to 21A at 14VDC DelCity 20A 125VAC But I want to switch a max of ~700W at ~30A, so maybe 23A? ...

I will say again. If you hook several different chargers to a battery system, be it 12 volt 24 volt or xx Volt. so long as all the charging systems are set to the same voltage.. IT IS NOT A PROBLEM. No switching needed, (NOTE This applies ONLY to DC systems) as the one with the highest output voltage wins and gets the job of charging while the others automatically idle or at the very least throttle back big time.
IF you are worried that multiple chargers might exceed the battery charge rate then (for a 24 volt system)
Run multiple charge controllers.. Stage one (All sources) set to like 30-40 volts, these the outputs go to the input of the 2nd stage. Set up for the battreies.. Or alternatevely you can get one that limits current only but .. While I know how to build one, I don't know where to buy one.
I agree, and routinely run two chargers together (2 solar, or 1 solar and the Meanwell PS).
But this discussion is about having two separate INPUTS to a solar charger: Solar panels versus the Meanwell PS.
