1000 Watt Pure Sine Wave Power Inverter ETL UL458 12V DC to 110V 120V AC 1000W for Home RV Truck Off-Grid Solar Compatible with Lithium Battery with LCD Display [3 Years Warranty] by VOLTWORKS

In a sea of look-alike inverters from unknown brands on Amazon, how does one decide what to buy? This is a detailed review of a Voltworks 1500W continuous (3100W 2 sec peak) inverter, why I bought it and how it has performed over the first month. Why Voltworks: I chose this company as it has been around for several years and has an online reputation for producing decent products and standing behind its 18-month warranty. I believe that it also manufactures Giandel and Leesky inverters, offered with slightly different features and prices. Though my inverter has had no problems so far, I asked customer service several questions and received answers within a day or so. “Alice” was clearly not reading from a call-center script, with detailed replies to difficult questions. In the box: The cardboard box has internal foam for protection, and includes the inverter, cables, remote control, spare fuses, and user manual packed neatly. The inverter itself measures approx. 8x13x4”, weighs 8.6 lbs, and appears solidly built — all metal and with heat-disippating fins all around. The 2’ red and black battery cables are paired 16mm2, which works out to almost 2AWG, i.e., better than the 4AWG cables in the Amazon listing. The wired remote control has 4 screws for attachment, 2 each of 2 types for use on different surfaces, and 3 spare 40A fuses are also included. A sheet of paper states that included pads are to be attached to the inverter base plate, but mine came with 4 cushioned pads already installed. Initial start-up: A key thing to remember is that before using it for the first time (or after a long period of no usage), the inverter must be run without a load for 30-60 minutes. This is to allow the capacitors time to charge properly, otherwise one risks the possibility of an explosion or reduced life expectancy. After an initial 30-minute warmup, the inverter did make some sound on the first load test, but quieted down on subsequent trials. Loads tested: I am using it in a house emergency generator system powered by my Toyota Prius, whose 12V circuit can spare a continuous 1200W at best, far below the inverter’s 1500W rated capacity. It is good practice to select an inverter rated 25% above its anticipated load anyway. With some combination of full-size fridge, small space heater, rice cooker, fans and lights (not all at the same time), I tested continuous loads up to 900W and initial surges well above that when appliances were turned on, as measured by a watt meter that shows range. I did not test the USB or hardwired outlets. System controls: The inverter’s low voltage cutoff system worked as stated in the manual, switching off momentarily at the voltage I set and restarting seconds later when the voltage had increased to normal levels. My setup does not need the remote control with 15’ cable, but it worked fine. The inverter’s fans were not noisy, and turned on only when the load or temperature exceeded certain levels. The approx. 1”x4” display has lots of data but was easy to read, and output wattage shown was consistent with that of my external watt meter. Connections: Input cable connections are covered with plastic caps for protection from shorts — a nice touch, though it means that cables to the battery can exit in only one direction if the (optional) caps are used. I spliced an additional cable to the included 3’ 14AWG ground cable and connect it to the earth with an aluminum tent peg. Note that per a Voltworks online video, opening the inverter to replace fuses requires unscrewing the output side plate’s 4 screws and sliding out the center panel of the top plate, after disconnecting the cable feeding the display. I am not sure this will be quite as easy as demonstrated. Potential improvements: * The almost flush, black power switch on the black side plate is hardly visible, especially in low-light emergency conditions, and should be a brighter color. * The 28 page user manual is far better than those of some competitors. However, it does have several errors; I was told that an updated version is being rolled out. * The included battery cables, while adequate, do not match the quality of Voltworks cables I purchased for use elsewhere in my system. Those are rated for 105C, with thicker and better-finished heat shrinks, and smaller 10mm lugs. Conclusion: All in all, I am pleased with this purchase and will rate it 5 stars for initial product quality and responsive customer service. I hope this review has been helpful, and commit to updating it as my experience warrants over the next few years.

Works great. Nice and quiet and uses little energy for the size.

Works great with my 2000watt power station with 2 100ah batteries

It worked good. I love it.

Installed this 2000 watt inverter to test and compare to a low frequency 2000 watt pure sine wave inverter. Overall works good. Some positives: low idle power 3 watts vs 40 for the low frequency. Runs an 18 cf refrigerator at 26 watts vs 60 for the low frequency. Haven't tested a 1100 watt microwave yet or tried my air compressor both of which the low frequency run. A few minor negatives: M6 studs for DC input need to be M8 at the smallest. Cables are marginal, I prefer 2/0 when pulling 145 amps to run a 1100 watt microwave.

Great inverter! I got this for my solar power system camping setup with my two 100 amp LiFePo4 batteries to use for cooking with a 110 volt induction stove (440 watts) and water kettle (400 watts). I needed pure sine wave power, and this unit delivers exactly what I need! It makes very little noise (fan) when operating - not noticeable. It gives very clear readouts on the LED display, and is easy to install and operate. I highly recommend this unit. As far as I’m concerned, this is the best inverter in this power range for the money!

Having already purchased the 1500W Pure Sine Wave Inverter for a work truck, I opted for the 1000W PSW for my daily use SUV. Both inverters have performed exceedingly well. I don't have a need for the full output wattage of either of the inverters but I had two reasons for buying the excess power. 1. I didn't want to have a cooling fan whirring in the background while making phone calls over bluetooth. 2. I often operate audio equipment which can have a momentary high power draw. During daily use, the cooling fans have not activated on either of the inverters. I did perform a test with a heat gun and soldering iron plugged in to verify that the fans would activate when needed. I took some photos of that condition but I didn't realize that I had been dropping sweat onto the LCD display and made it unreadable in some of the photos... hot summer days. The fans are not loud but are noticeably audible. A very cool feature of having the inverter in the cabin of your vehicle is that it's like having the actual car battery at your fingertips. I added taps to the terminals of the inverter and connected them to the reverse-gear signal of my double-din stereo, with a multi-position switch in-between. I can now use the switch to alternate between my vehicle cameras on demand. The wiring is easily concealed and didn't require disassembling the dashboard to tap into the vehicle 12-volt lines. I no longer think of my vehicles having a 12-volt limitation and it's now 2nd nature to simply plug in any power tool, lighting accessory, or audio component without concern. The Pure Sine Wave is a must for audio equipment and power tools benefit as well. I own a DeWalt 1000W Modified Sine Wave inverter and it's now sitting on a shelf. I can hear a difference in a metal grinder running with the Pure Sine Wave inverter and feel the tool doesn't get hot as it does with the Modified Sine Wave inverter. I run the inverters for a couple of hours continuous use each day and neither of them have shutdown, blown a fuse, or drained my truck battery. The customer service at VoltWorks is unmatched. They reply right away to an email inquiry and are very solution-minded. With solar panel projects in my future, the reliable customer service at VoltWorks means they will be my first choice for inverters.

Real sine wave, very stable. Tested with input: 11.9V Values with no load: RMS: 118V Duty Cycle: ~ 50% Frequency: 59.9 Hz Vpp:348V 40-80W Noisy inductive load (Dremel 10-35K RPM) RMS: 119V Duty Cycle: (+)51% (-)49% Vpp:352V Seems very professional electronic design. I'm really impressed at the quality of this product, and honestly hope it lasts and I don't have to come back for a negative review on durability. See reference pictures and video above.

Works perfectly and quite fan only runs on heavy load plus you can see the watts and volts

Seems a good inverter. Been using it for small loads like the internet router.. Great thing is low idle amp draw around 300mA. Bad thing is that upon power up, it ramps the output voltage 0-120v. It might kill some things that are plugged into. Never saw an inverter doing that. Be sure that the inverter screen shows 120V before plugging anything into it. Battery connection can be better. Thumb screws for a 100amp load is not great.

Arrived on time. It works and it does what it is supposed to do. I have used it only for a short time so I can not comment on durability

A bit bulky but works perfectly. Even when fan kicked in, it was fairly quiet. About 90% efficiency which is, in my book, very good. No problems pulling 1100 W for about an hour. It did get warm but not hot.
