Hi,
I'm looking for a device that has two inputs and one output. It passes one
of the inputs to the output.
It defaults to one input on power-up, and then switches to the other input
when a signal is applied.
What's it for?
I want to run a battery bank through an inverter to supply one or more house
circuits. When the batteries are getting low, I want to switch
(automatically) to mains power.
So, the device takes my inverter as one input and mains power as another
input and selects between them. Ideally it would take a voltage measurement
from the batteries and make the switch when this voltage goes below a
certain point.
This is so simple, I can't believe I haven't found such a device yet.
I guess it's probably because I don't know what it would be called, so I
don't know what to search for.
