I will assume that your solar panels, charge controller, and battery bank
are sufficiently robust to handle the entire repeater load, including the
accessories. The solar charge controller is a critical part of any solar
panel installation, and it is important to ensure that it has

Laryn,
The simple, and most practical solution, is to use a 3PDT AC relay to switch
between normal and emergency sources. Feed the coil of the relay from your
normal source, and wire the hot, neutral, and ground from the normal source
to the NO contacts, and the hot, neutral, and ground wires
Laryn,
Your thinking is good. A simple relay, 3 pole/double throw would do what you
want and power the relay coil with your normal AC power. When it goes the
relay drops out and connects the repeater to the RED emergency outlet.
As someone else suggested switch all 3 wires of hot, neutral
Sorry, Ron, I disagree with the relay idea. If it's critical that the radio

ARE active all the time. Our main ambulance radio and our maintenance repeater

Plug the repeater and equipment into the UPS and then plug the UPS into
