Will this still work on my solar power system, I want to go from the 12 volts I currently use to 24 volts as an upgrade?

the voltage difference is no problem keep the amperage under 300 amp.

I purchased two of these a while back and I do not have a clue how to instal them in my solar system. Help please

I use one between my panels and controller to allow me to disconnect the panels and another between the controller and battery bank. Rated for 300A but these are cheap knockoffs of a name brand and I limit them to 100A.

would this work with my alternator and all my hot wires i need power too??

No, it only runs off of 120v power.

Can you buy just the keys?

We do not have keys available separately.
