Voltage Switches... your suggestions?

Im looking for a voltage switch for my 12v fridge.
Does anyone know if there is something like this on the market?

Im good with electrical but not electronics from scratch so not keen to tackle that project.
3 outputs set at different voltages would be great eg.
If running from say 120w-240w panel.
13v fridge turn on.
13.2v exhaust fan on.
13.4v small 60w inverter with phone chargers ipod charger etc.
Anyone have ideas?

I don't know of any one unit with multiple outputs (e.g. three different activations programmable at different levels) but Voltage controlled switches/relay drivers aren't hard to find:

They cost a bit, though. Relays needed to handle high current, of course.
There are also small charge controllers with Low Voltage Disconnects which could 'drop out' a device if battery Voltage went below the set level. These aren't meant to handle high current either.
One example: http://www.solar-electric.com/ss-20l.html
The high-end charge controllers like Outback FM60 have a programmable AUX function which can be used to turn on/off something according to user selectable parameters.
Just some options to consider.
It will work with Morningstar combination Relay driver and Tristar PWM or MPPT. It can control up to 4 relays. Use it the free Morningstar software MSView to configure your ON/OFF voltage.

And relays. I used a switched relay outlet that Turn ON/OFF based on what the relay driver tell it to do. A switched oulet like Middle-Atlantic RLM-15 that connect charger when the MSView tells the relay driver to turn on.
Do you guys know if the sunsaver 10 with LVD is user adjustable?

I don't believe so. Looks like your stuck with 11.5V disconnect and 12.6v reconnect (12V).
3 equipment at 3 different voltages = relay controller
Suggestions of an affordable one, its just really to run my fridge... 12v 4.5a
