Did you try RMS for your monitoring / control hardware?
http://www.bndcom.com/rms/rms.htm
They are $500 list, have 3 relays remote controllable - NO/and NC
connections, so if you want a fail over to closed you can do it. There's
5 or 6 voltmeters, a 1/2 dozen TTL level contact closure sense items,
low current draw - decent scripts.
Haven't seen any for $200, but the guys at BND have said they are
working on a new one - maybe lower cost.

What do you mean by thermo-electric generator? Something that works from
Geo-Thermal sources?
Sterling has some interesting stuff. .:_)

Great ideas. We've built lots of remote sites and frankly $800 / hour
for a heli ride when things go south is crazy. We just don't do it. :-)

Since I was laid up for a month and more, I began doing some research
on developing things I needed. Before I go into a bunch of work to
try to finalize these... I'd like to know if anyone else is interested...
1. IP addressable, 10/100 ethernet based voltage / charge /
temperature / monitoring and/or switching device. You
could monitor batteries, solar panels, generator, start/stop things,
etc. Cost: ~$200
2. IP addressable, 10/100 ethernet based thermo-electric generator,
fueled by propane, either remotely controlled, or operating on a
programmable basis - to operate as a backup power supply in
conjunction with 12 or 24V battery based DC systems. Would provide
battery monitoring, as well.
Approximate cost: $2500 for a 75 watt 24V system. Could be made in
20, 50, 100, or larger wattage sizes - cost rises considerable with
power output. This would serve as backup for a solar/wind or even
for AC in conjunction with lead-acid batteries.
3. "crash detect and reboot" system. This would connect via
10/100M ethernet to a network, ping a programmable IP (in fact,
several of them) and be able to power cycle dc or ac powered
equipment. Programmable as to how many pings to miss, how long to
power down, etc. Cost: ~$200.
Each of these devices would be designed to operate on very minimal
power and tolerate temperature extremes.
