Does it display Amps and Watts? (no 220) I don't need any $ numbers as I'm off-grid. I want to know the draw from my batteries at night.

This measures AC power in watts and amps. The Efergy True Power (version) is much more accurate as it calculates power factors to give you more accurate results in watts and watt hours consumed. This unit does not measure amps or volts. If you want to monitor your batteries and their charge status (measure amps, voltage and track amp hours consumed) then you will want something more like Xantrex Link or Link pro, or Trimetric makes a power monitor system that is pretty popular. These devices will monitor your amp draws and keeps track of the amp hours taken from your batteries (much like a gas gauge does on a car). This measures AC power in watts and amps.

The Efergy displays Watts. Both instant current Watt readings, daily totals and daily averages. Local rates can be entered to show costs, but that feature is not necessary to use.

This is not a "power meter". It is more of a novelty or home economics type product. It is not accurate enough for power management. It comes with two current sensors but you have to program average line to neutral voltage in. It gives you Watts, which is pretty useful for trimming household electrical loads and budgeting, but it is a good estimate at best. I love the thing for it's simplicity, easy of use and the data logging.

This measures AC power usage in watts, kilowatts and watt hours. To monitor your batteries you probably want something like a Zantrex Link Lite or Link Pro which shows battery voltage, Amp Hours used and can be programmed for the capacity of your battery bank to show your particular systems- "Percent of charge used" and hours till empty as well as alarm outputs for when you your batteries are running low (which can trigger a generator to start up or just an audible alarm).

It does not have this information, but you can calculate, it has 7.00 amp and 120 v, the watts aprox is 850 watts.Regards

Mine is hooked up to 3 batteries about 100 AH each and with no load, it draws 1.43 amps. My meter is plus or minus 5% so it could vary slightly more or less. I hope that helps.

I checked the box that my lights came in and it says 1.9A @ 12v, 0.8A @ 24v. It seems like when I installed them I checked the current draw and it was about 1.0A but can't remember for sure. However, using 27 watts and 12 volts it calculates out to 2.25 amps. I know mine are not drawing near that much.

Can this unit be used to find out the max wattage an appliance uses? I just purchased a portable generator, and would like to see what some of my appliance pull in watts. Thanks

yes it's a 3am draw on the current, if you get a chance go by any electronic store, (radio shack) or (best buy) they will place it on the meter for you at no cost.... i hope this helps

Yes it tells you what is going into the batteries from your source being either solar, wind, water, or any other generating DC only current. Also tells what the voltage is of the load battery when no current flow exists. If input voltage is lower than the voltage of the load the input voltage may be shown and not the output because there is no current flow. A very good instrument if you have any kind of generating DC source within its operating ranges.

It depends on how long you want to use the power inverter and how many watts per hour you are going to use and will you be charging the battery at the same time or just use a battery without charging .The formula is (amps x 120 v = watts X hour) amp draw should be listed on tag by the model number

The MT-5 will not show how many watts you are getting from your solar panels. The watt of your solar panel you can find it in its instruction.

Voltage is not measured in Watts.....5 volts. It draws 0.4 amp or 400 mili Amp most likely. (it also makes sense). But why are you concern about power input??

Sorry I can't help you on this yet. I bought these units to give me readouts on my battery supplies for my solar power system and I won't be putting the system together until this summer. The meters are in Montana at my cabin and I will be here in North Dakota working until spring. So don't have access to them or the paperwork that may have come with them.

Not really, unless you consider that to get it to light up, there is a minimal current draw while the unit is lighted up. When you unplug, there is no current draw. It really doesn't "Test" to get an accurate reading. It just shows what the battery reading is.

Yes, gives voltage for solar output, both voltage and amps when battery mode is selected. I have nothing connected to the load terminal.

"Wattage" is normally shown as "Max" wattage when in operation. If this product is listed as .8 watts (120vac x .067ma) then the "idle" current should be significantly less, probably about .020 amps/20ma or 120*.02= 2.4 watts. It could easily be less, depending on the circuit design. When the lights are not on, the unit is 1)determining if it is light or dark (dusk to dawn sensing) and 2)if there is "motion" in the vicinity. The energy used during this "idle" process is extremely low.

Two ranges, it will read out any amps but you will need to adjust the insensitivity by settings the decimal point. Otherwise you may get confused by all the numbers on display. I try to move it to the right for less numbers.

I just took these readings from my solar charge controllers remote display. It appears to draw about .4 amps on low and .5 on high. I ran it for a while on both settings and it held steady at those readings. It was plugged into a cigarette adapter I'd install in the RV for small load devices.

It is rated for 10 amps input and output. If it can handle 48 volts (which I don't know because I have a 24 volt panel) it will receive 48 x 10 or 480 watts (volts x amps equals watts). However, if you are charging 12 volt batteries it will only put through 120 watts. I ended up trading this in for a 20 amp controller because of this. I am very happy with the 20 amp controller.
