FYI
The Vector brand of inverter that I bought from
www.invertersrus.com
can be ordered with a remote turn-on switch. It plugs into the inverter control panel using a telephone-type connector, has an about 16 foot cable attached, and a neat little contol panel. Looks like it's designed to be used for a motor home or something. I mounted mine in a neat cutout in my glove box - works like a charm.
