3000 Watt Pure Sine Wave Power Inverter 3000W 12V to 110V 120V AC, 6000W Surge Peak Power for 2 Seconds, UL Fuses, Compatible with Lithium Battery, Car Off-Grid Solar RV Truck Vehicle VOLTWORKS

I had been using a old teeny MSW inverter in the barn, attached to a couple marine batteries (of which I used to zap every so often with a regular battery charger). My wife bought me a couple of solar panels for this Christmas, which then started this saga.I decided I wanted to upgrade "my system", so I originally sprang for the 1000 w Voltworks PSW inverter (mid Dec.). Upon arrival, I immediately tried to "hammer" the unit - I plugged in a 10 amp skil saw to it, to cut the plate I was going to mount it on. I could not believe that the darn thing did it - I was truly impressed! A couple of days later, I gave this unit its second test - I ran a 100 ft extension cord (12 ga) into the house, to see if it could run the fridge (Whirlpool - 6 amp - according to the plate). Unfortunately it failed. Checked the fridge with a kilowatt meter, and it starts up at 1240 watts, then settles down to about 260 for operation.I decided that I wanted to actually be able to run the refrigerator off an inverter during outages - so I boxed up the 1000 watt unit for return, and ordered the bigger1500 watt unit from Voltworks (to handle the startup spike).What amazed me thoroughly, was that during the transition of units coming and going - Grace from Voltworks took the iniative and contacted me regarding my inverter application! After my explanation, she suggested that I go to the 2000 watt unit, to ensure I had enough headroom in wattage, as my fridge is not a newer "energy star" type. I probably would have done that, but the 1500 watt unit had promptly arrived - so I decided to give it a whirl!I wired it up using the same 2 gauge cables - and hammered it with a 1500 w oil heater (on high). The kilowatt meter showed it pulling 1480 amps - I left it run for about a half an hour, and the new inverter didn't even break a sweat! On to test #2 - I stretched the 100 foot extension cord back into the house, plugged in the kilowatt meter, then plugged in the fridge - AND IT RAN! I left it on for about an hour - and again, the inverter did not even break a sweat!As a final test, I killed the main breaker to the house. I then back fed the inverter to half the house through the hot tub 20 amp circuit (which goes straight to the breaker box - yeah I know this is a no-no). This 1500 watt unit is running half the house with lights, two TVs on it, and it's the circuit side with the fridge on it! WOW!While I could have gone with a bigger unit, I wanted the minimal inverter needed - as to minimize the loss of energy consumption during standby. My initial observations are that I really like this 1500 watt unit! I love the solid build quality, and the fluorescent display which gives you the critical information. I recommend using 2 gauge or thicker cabling to feed it (they send 4 gauge with it) - because it seems this thing is quite a monster! I having this on site, it allows me to QUIETLY cover the essential needs during power outages - and I can recharge the batteries via solar, an existing gas generator, or even off the alternator of the truck if needed.This is my first Voltworks product - and I paid full price for it. I have used Samlex and Xantex in the past - and this unit appears to be on par with that same quality. The fact that they contacted me regarding my application, and the three-year warranty included with this unit, gives me confidence that this unit will perform. I hope this review helps any of you out there, and I will update if there is anything else to add.

So far this 1000W inverter works great. When off it draws zero amps. When on with no load connected it only draws 0.36 amps, that is great. The display is pretty accurate; battery voltage, output voltage, and power. Note the display will not show power if using less than 20 watts. Fan is very quiet, and only turns on if using over 400 watts. Very happy with this purchase, it is a great value. Real word efficiency (watts drawn from battery vs watts used by the load-connected devices) varies between about 74 to 86% depending on how much power is being drawn and the type of load (e g motor vs resistive load). The output voltave can vary from 118 to 122 volts depending on load, and that is fine.

Got this inverter for my mini-camper (S10) set-up. It is fed by two 12v 100Ah LiFePO4 batteries in parallel which are charged by a 40A DC-DC charger coming off my truck's agm battery and 200A alternator (4.3l v-6 Chevy). This Inverter puts out plenty of power for small space heater, electric blanket(s), small microwave, m18/m12 milwaukee battery charger(s) and easily charges my Yoshino BT2000SST power station at full speed (about an hour from empty to full charge!) I'm very pleased with this inverter and installation was fun, simple and problem-free. [I used thick cables to connect this inverter with the Deespaek batteries and ran a 2-gauge marine-grade cable inside the truck's frame rail from the engine bay to the camper via a rubber-grommeted hole in the front corner of the living-area/truck bed. I also ran a 2-gauge ground cable directly to a sanded-down hole on the frame rail below the camper/truck bed. I fused all positive connections and used breakers between everything for added safety. I have solar panels for clear, sunny days or when set-up at an un-shaded camp-site but for mobile, on-the-go power or device-charging while driving, this is the ticket! Thanks for reading!

it works as an inverter but read outs are fairly inaccurate. I have in-line shunt in my system and inverter is pretty substantially off. seems like a screen readout was just in an effort to charge more money for the unit. you shouldn't rely on it's readings if you want accurate information about your system. i suppose for a simple 'hook up to the car battery and see if it works type setup' this will work good enough in a pinch.Battery leads that come with it are undersized for the rated current. Get yourself a properly sized 4ga stranded pure copper if you want to draw and come close to the actual rated current of this unit rather than just couple-three hundred watts.

Great inverter.Highly recommend it. if you need one.Harold Wayne Hall

I've been running this 2500 w inverter for over a year and it has been Rock solid. I run two refrigerators and a freezer continuously plus a 5000 BTU air conditioner in the summer without a hiccup. I'm getting ready to move to 48 volt and if they made a 48 inverter I would buy it without reservation. This unit came with a 3-year warranty which I doubt if I'll ever need. These people make a quality product.

There are plenty of underpowered inverters on the market. This one has some real power and some worthwhile features. If you are shopping for an inverter with some serious power, give thoughtful consideration for this one; it is excellent.
