Hello, I was wondering what the no-load power draw is? In other words, how much energy is it using when nothing is attached to it? Thanks!

According to the documentation on their website the no load power draw is less then 0.6A here is the link. http://www.xantrex.com/documents/Power-Inverters/PROwatt-SW/DS20101206_Prowatt_SW_600_1000_2000.pdf

Honestly, I have no idea. I can't imagine that it is much of a power hog, though. I guess I could measure it...

Nope! No power needed to use the gym. It uses body weight and no electricity!

I believe it writes data to hard drive, so it does not need constant power. I have lost power and unplugged it a few times with no data loss.

No need for power. I haven't tried it on any other laptops, just my Leveno.

This IS an off-grid system. I have never been on-grid at my present location. I run 24/7 with 4 of these kits (8 panels), feeding a set of 4 panels through the included 30-amp charger to recharge 3 large deep-cycle batteries each set (6 batteries altogether). The batteries feed an 800-watt Cobra inverter (also from Amazon) to provide all the power I need. For high-drawing electrical shop tools, I use a 3500-watt LPG generator. See my video series at my website, DroidPals dot com.

We use the power supply and not a battery. Last week we had a power outage. When the power returned we simply turned the unit on and everything performed without retuning.

No. It is a good inverter though. Some inexpensive inverters will use a lot of energy even if they have no load on them. This one doesn't. Very important when running something that cycles on and off like a refrigerator.

I found on the manufactures website it said, 1 kilowatt per 24 hours. That seems like an average and should be the best answer if you're trying to compute operating cost. If you're looking for load on your electrical system that is where I'd have to start guessing, but I couldn't imagine a situation where it was drawing even half a toasters worth of power. Not very scientific but maybe it still helps

A couple of things here to say... This unit should come with a supply... Seems like mine did. On that note, the unit take 15 watts or a little less than 1.5 amps (18 watts). I would get a 12 volt 2 amp dc switching power supply with a 2.1 mm jack on it. You want your load to only be about 80% of your supply. Another advantage to a switching power supply is that when the load does not require the full power (day time IR LEDS are off) the power supply consumes less energy. I would suggest getting a bigger power supply and a splitter and hook up several ... A 5 amp supply show power 3 of them. If the power supply you received with the unit is only 1 amp, it's already under powered.

I had it over-loaded with christmas lights for a float. At least 900 watts, likely more and all of it continuous load, not surge. We pulled that float all around town and probably got 3.5 hours out of it (maybe more) before I had to refill. If you ran it with a 700 or 800 watt load and didn't get at least 4 or 5 hours, I'd be suprised. Having said that, we did this 9 and a half months ago so the details may be a little fuzzy... But I honestly was very suprised how well this little genny ran. I actually expected it to fail due to how long we were running it with that heavy of a load. I wouldn't try that heavy a load for that long if I was using this as a home power source. Remember you are getting this guy for under a hundo...

You mean no-load current? According to manufacturer's spec, no load current is 1 Amp and 0.1 Amps with PowerSave mode, translates to 12 watts/1.2 Watts, although I'm NOT sure why this inverter incorporates manual PowerSave mode. It doesn't take much to add automatic power save functionality in the circuit. You really need to go to go to manufacturer's website, and download the specifications.

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.

Thank you for such a quick reply! I currently have a Cyberpower 450va and the computer, monitor, and WiFi router are plugged into the battery backup section. It works fine. I recently had FIOS installed, and got the Optical Network Terminal (ONT) without the battery backup. I was thinking of buying the larger CyberPower 850 to be sure it could handle everything (for a couple of minutes until our generator starts), especially since I have no clue how many watts the ONT uses. Thanks again for your response.

I'm not sure what it uses by just being plugged in. It's max capacity is supposed to be 2400 watts. I have a computer plugged into it that is always running as well as a few other things in my recording studio that always use a little power. I don't think it uses much on it's own. I have 4 of them in different locations and I haven't seen any increase in my electrical bill using them.

What kind of load do you have hooked up? If it's an open circuit, there won't be any current.

I haven't noticed an increase on my electric bill and haven't measured electricity usage specifically for this device. It does go into a sleep mode when not in use. When we are going to be gone or won't be using the computers for a while ii usually turn off the power supply for this and the rest of my network peripherals.
