I am trying to size a solar power system to run the telephone system at our reseach facility and need some help. Before anyone suggests power and phone lines, it would cost us $25,000 just for the right-of-way to run them plus parts! 8-( We do have two 15 KW generators, but try run them only when we need real power. All other power is hand, battery, solar, or small portable generators. I am considering using a Panasonic KX-T61610 switch fed from a Radio Shack cellular phone mounted on a building (I checked, we do have cell coverage and only need one CO line, the rest are intercom/PA). The questions are: 1. How much power does the Panasonic unit draw from the battery input and at what voltage(s)? Pinout of battery connector? 2. How much power does the cellular phone draw with the modem adapter and horn alert (to drive ringer to Panasonic)? 3. Is this legal in California? 4. Any better ideas?

Better yet, find one (your local supplier will have one around, or won't get your order) in a working state and bring your ammmmmmeter along. Don't forget to plug in a device to all the ports and take them off-hook -- they're line-powered! Now, if you could just use 48 Volts, you could snarf power from TPC directly and not have any power costs :-)!
