The description says 40V max, but output graph shows just under 18V as a max (no load). Which is it?

The 40DC Volt rating is the absolute Peak Voltage rating. It can be reached only by pedaling at the most extreme speed humanly possible.

Yes ours is a 20 volt max. It should say on your instructions your max voltage

I added a picture of the power supply showing the voltage here: http://www.amazon.com/gp/customer-media/product-gallery/B005YXXTAQ/ref=cm_ciu_pdp_images_dav

Correct. The TOTAL output current is limited to 2.1A max. That means you can draw 2.1A from one port only, if all other ports are not in use. Or you can draw 1A each from two ports, and so on. If you exceed the current limit (for example, 3A total), the converter will still run for a short while. But eventually it will overheat and burn out.

On the silver part of the bulb housing, it says 125V 40W, so I'd say it is 125V.

I've been running one for about a year now, no problems except I was using the load output to control some outside lighting (on at dusk, off at dawn) and it seemed to get confused and was turning the lights on and off randomly. I disconnected it and let it sit for a day and then reconnected it and it has been working correctly since. I am running a 100 WATT 12V panel into it, are you staying within the maximum input power and voltage levels (12v/260W or 24v/520W) specified?

"350 Watt or greater power supply with a minimum of 18 amps on the +12 volt rail." Taken from the box. Hope this helps!

There is no "output voltage". It's simply a switch. I'm fairly certain it can handle 24 Volts.

I believe its 120 volts just took it out of the case last month have not used it yet the job was canceled i bought it for. will check this weekend.

So I'm not gonna sugar coat....the breaker opened at 4800w surge on test. Meaning 20a @ 240v. Might be the cheap Chinese breaker on the unit, might be a realistic shock load for it to bear.

The max output for the USB ports is 5 volts. But there is an adapter allowing you to plug the main 20 volt output into a usb outlet.

Honestly I'm not sure, I have never checked the voltage... That would probably be a question for the manufacturer.

The label says 1W. I plugged one into a kill-a-watt meter and it shows .02 Amp. (20Ma). Problem is it show this regardless of the switch setting or whether the LED's are on or off.... This unis has not been plugged in so the battery may be charging. I will leave it plugged in and update this info after the battery has had time to fully charge.

If you're looking for the "preout" rating - the maximum is 4V. If you're looking for the output rating of the unit, that's measured in watts and it's 22W per channel. If you're really looking for power consumption, that's rated in amps, and it's 10A.

Their book specifies Max PV input power 12V/390W or 24V/780W. My PV output is max 18V at 21A. That is 378W (18 x 21 = 378) and does not exceeded their specs so I don't have any experience as far as exceeding the books specs. Going from a 12V to a 24V PV system will double your wattage without increasing your amperage however, in order to use that increased wattage without exceeding the 30A output current, you would also need to change to a 24V battery system. The output is rated at 30A regardless of the input voltage or amperage or battery voltage.
