Does the Current Meter read the actual output load? or is it only a fixed max setpoint?

Current is adjustable. Voltage is adjustable. Each has their own "screw". There are electrical limits to both of course. If you drive more than 3A make sure you cool it with a fan or similar. Works great for me. I have 20 of them in a lab setup.

The converter itself has a max output. The ammeter actually measures the output current going to the load

It displays the current that is actually flowing. I didn't see a way to have it tell you what you are setting the limit to. So I had to connect a load and then adjust it to see where it was set.

yes but remember you voltage is close to max, my max with PV is 19.2, the meter works great. DS

That is correct. Note that the hour meter is not resettable. The other answers are also correct.

About 22, doesn't matter since there is no load other than the meter itself which is in the 10ma range

I just read the online user manual, and watts is one of the readings you can get. See pages 9 & 10. http://www.p3international.com/manuals/p4460_manual.pdf

It will monitor total wattage. But you will know how much each individual device consume once you turn it on.

Basically you push buttons to view present voltage current and watts or power factor and accumulated kWh (energy consumption over time). This article might be helpful: http://greenhomearchitect.com/2013/11/22/weekend-project-where-is-all-my-electricity-really-going/

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?

I've been using it side by side with a digital usage meter provided by my utility company (SMUD) and it is always within 30 Watts (shows 30W less). Not a scientific test though :).

The meter is not symetrical, and one side must "face" the source of power, as outlined in the directions. Double check you have that right. From your description, I don't know how you have the panels wired. I would suggest you test only one panel at a time, and see if it produces 80% of it's rated power output when in direct sunlight and when the system is under a load. You could have a defective panel, a short, etc. (I'm assuming that you have already tested the meter using just the battery and a load and know it's okay)

my understanding is that the source side must be the most positive than the load side.also the measured current is only on the negative side (black wires).even with zero current the meter will still read zero provided you have at least 4v between the red and black load lines

I highly suggest you check the output voltage. This has no built-in display, and you should not assume it is the voltage you want when you take it out of the anti-static bag. As you adjust the output voltage, the meter reading will increase when turning the pot in the direction that increases the voltage. Make a note of the direction when you first adjust it. It doesn't jump back to max. It goes to max or min and stays there if you keep cranking on the screw.

No, it only acts as a switch to control one of the two outlets, based on the commands of the controller. Amount of Watts used is not tracked by this device.

Yes, that will work. The meter reading will indicate the value of the power source voltage. Instant battery voltmeter if that's what you want.

In practice these things are pretty robust. As long as you do the adjustment while there's no output load (just your meter connected) and don't exceed the maximum rated input voltage, you're unlikely to fry it.EDIT: It sounds like one blew up on you, sorry to hear that. This is surprising to me, since the LM2587 has undervoltage lockout. I bench tested this for my application (dropping the input voltage until the thing turned off) successfully several times under 10W load.

There is a tolerance in its output. I do not remember what it is but the instructions that came with the unit and its maker can give you the specifics.

All I have is a hand held meter with a needle. It displays 2.1 amps on start up. I am using an Active Air variable speed controller with mine. http://www.amazon.com/gp/product/B003URBQ1M/ref=wms_ohs_product?ie=UTF8&psc=1
