High Voltage DC Switch Source for Solar

If you only want a disconnect for maintenance, communication stations battery standard is 48 volt. You can find circuit breakers designed for that, they are under $20.00 and not very large. I am the most conservative person there is about getting shocked, but the 48 volt (station bus was capable of hundreds of amps) would hurt some but did not do any damage if you hit it. Something you did not want to do even once
