Power Inverter 1100 watt 12V DC to 110V 120V AC 1000w Inverter with LCD Display Remote Control 2AC Outlets Dual 2.4A USB Ports Compatible with Lithium Battery for Car RV Truck Boat by VOLTWORKS

I bought this inverter when I changed my system configuration to 24V. My old inverter was a 12V 1500Watt Pure Sine Wave and ran about 115V. It ran most things well, but couldn't handle my large ShopVac, and even with a minor load the fans on the inverter would cycle every couple minutes. This inverter runs everything I plug into it including a ShopVac and Refrigerator simultaneously. Its output is ~120V, the voltage drops little with heavy loads. Running 1,200 watts voltage does not go below 117V and averages around 118V. The fan rarely operates, in-fact it never cycles when the continuous load is less than 150W. So for me it will run my refrigerator and be absolutely silent. Had me worried at first that the fans might not work but the unit stays cool to the touch and the fans do work. Fan only runs when the unit hits 104F, so just keep the inverter in a nominal conditioned space of <80 degrees and you are good. My tests show it meets the claimed 90% efficiency and no load current of .9A (inverter on but no load). Power when turned off was in the milliamp range. I disliked the remote and lack of information on the pin-out as I use a relay to start the inverter. To turn on the inverter you either; push the button on the unit, button on remote, or use a relay to short pins 1+2 at the RJ9 port for ONE SECOND. Shorter duration will likely fail as the unit has to come up to the proper voltage for startup. I disliked the use of an RJ9 port, this is the narrow plug used on telephone handsets. Making it "unusual" to work with. And I had to buy some RJ9 crimp plugs for my bench stock. The information on the RJ9 port pin-4 is some kind of pulse coding, almost looks like garage door coding on my scope and the pulse duration and amplitude seems to follow the load. I am simply processing it as an analog signal (milli-volts) to determine if the inverter is on or off. The handheld remote provided does work, but having that wire is like being tied to a leash. Just seems like something you would have in the 80s. Hoping to get more information from the company. Other than those few issues, I rate this inverter as Excellent. 1 Year Update: - Zero issues with this inverter for the past year. Not even an overload restart. - I use it 24/7, my daily peak is about 900Watts but on average I am drawing 280Watts from it 24/7. - Running from the inverter 24/7 are: 1 standard 17+cubic foot Refrigerator, 1 Air Cleaner, 2 PC Computers, 1 Base Station GMRS Radio, 1 Laptop, 2 End-Table Lamps and several USB charging stations. - Unit runs at 92% efficiency which is above the stated 90% efficiency. So for me if I draw 1000Watts of DC from the battery will run 920Watts of AC loads. This is great efficiency for any inverter. - The outlets are NOT GFCI (ground fault) protected. This is now a USA code issue for household inverter power, if you wish to have this feature I recommend you buy a GFCI with a pigtail plug. You plug that into the inverter and connect your loads to it. - GFCI or not make sure you ground the unit case solidly (quality connection). In addition (meaning you still need the case ground), you may want to connect the one of the inverter outlet grounds to a grid ground receptacle. DIY two male plugs and one wire, a 12AWG green wire. Just make sure both ends connect to ground or be ready for sparks and flames. - I stopped using the outlet signal from the RJ9 plug (pin 3/4) to determine on/off status of the inverter. Instead I use the 5Volt signal from the inverters USB port to determine status. (dah on me for not doing this first). And this USB method would likely work well with a small 5Volt relay. - Still using RJ9 port pin 1/2 to operate the inverter. Remember, needs to be shorted for 1 second to turn the unit on. - Picture 1 shows my rather custom and elaborate setup that may help some of you. - Picture 2 I included only for the DIY aspect of the lighted plug. Really some good benefits to using these lighted plugs... its lit so the inverter is on and electricity is at the plug. - I have an external box that my loads connect too. Inside the box I have a dual pole 16Amp supplemental circuit breaker and a contactor. The circuit breaker is as stated, supplemental. The contactor I use with a control system to transfer between inverter and grid. - This is a high frequency inverter so it is best for non-motor (non-inductive) loads, but clearly it handles my refrigerator and occasionally my shopvac without issue. However, if you plan on running something like a sump pump or AC at 1HP or more you may consider a higher rated inverter, or a similarly power rated Low Frequency Inverter. Low Frequency Inverters are bigger and cost more... But nothing beats getting the right stuff for the task you require of it. Bought a Second One My systems operates 24/7 as Off-Grid inverters do. Most of the components in my system were redundant. Multiple panels can be reconfigured, 2 charge controllers, 8 batteries etc. But the one single point of failure for me is the Inverter. So after running the first inverter for over a year with zero problems I bought a second one. Bagged up the first one and the second one has now been running flawlessly 24/7 for just over a month. The plugs were exactly the same, and it is performing exactly the same. My inspection of the unit that has been running for a year showed absolutely nothing of concern, and I was happy to see not much dust/dirt buildup on the fan or components. With electronics in general if they run for 90 days they tend to last a long time thereafter, often called a "burn-in" phase. Thinking this was another home run.... will do a third update if it proves untrue.

Love it works great. Low price. I've used it 2 weeks.

Update 4-26-2021 My system has grown quite a bit and I have lots of new equipment. Although it might not look as clean it is much more powerful and the inverter now runs flawlessly day and night. I basically never turn it off except when the sun doesnt come out for 48 hours or more. My shunt shows I run about 70kwh through the inverter every month. I can confirm that this will power a 700 watt microwave with no issues at all. (700 watt advertised microwave is actually 1100 watt draw, which is 1300 after inverter efficiency losses.) Also have tested a 5000 btu window unit air conditioner and it works just fine. I am very pleased with this item :) Update 6-18-2020 Voltworks responded promptly to my email and was very courteous. They asked questions about my unit and took care of the problem right away. I am currently waiting for a replacement to arrive and im happy to see this company honors their warranty! Update 06-12-2020 I have been using this inverter everyday since the day I wrote the 2nd review with a new set up (vertical) and it has performed flawlessly until now. This morning I turned it on like I do every morning and it gave a very loud buzzer so I immediately turned it off. waited 10 seconds and tried again and nothing. No sound, no lights, no power at all. I have emailed the company as the photos and the box which I still have both state 18 months warranty. I have not yet received a response but will continue to wait.. Update 10-15-2019 So far ive used it to charge my macbook, power drill, gopro batteries, a few portable power banks, and a fan. No issues to report! Works great! (oct 3 2019)I was worried this inverter might not be enough just because i have a doubtful nature and i could not find any videos of it supporting a tv that is 55" Took a chance and i am happy so far! Tested it last night and it powered my 55" for 2 hours off a 100ah AGM battery. Worth the money!

high quality construction, supplies clean power to low power devices during power outages.

Worked right out of the box, no issues.

I've had this running 24/7 in my solar system for about 3 months now, in the window between 1/5 and 2/3 of rated load the entire time, usually around 1/3 to 1/2 being most common. It has worked great! Only thing I've noticed any real difference from utility power is with my Hakko soldering station which buzzes on this and not on utility for some reason (still works, but I'm leery of using it.) The output voltage sags more when connecting a switch mode power supply for my laptop than a normal utility circuit, but given the low wattage rating that's to be expected, and it's very brief. Sometimes that does reset my iLC/Hekee/ChangM/YangCSL (all have intercompatible remotes) LED light bulbs, but not a big issue. When i put it in service, I ditched the cigarette lighter plug, cutting the cord at the halfway point and adding an XT60 connector to it and to my power source (also added a mini blade car fuse, but not one of the untrustworthy no-name ones!). That is a MUCH better solution! Sadly, running my Ryobi hybrid soldering station on high for 10 minutes to make the joints caused the station to burn out:(... Probably just the heater, but due to a bad design that's not separately replaceable:(... We tried an antique radio known to be susceptible to power line noise. Even with an added inline filter there was significantly more noise than on utility power, though nowhere near as much as on a "modified" "sine" wave inverter! (that waveform, though in fact a waveform, is not merely a "modified" version of a sine wave, nor indeed anything like a sine wave at all, being nothing more than a square wave with an extended zero crossing twice per cycle. The term was probably invented by marketing somewhere.

I have purchased several of these inverters over the years with zero issues. This particular inverter stopped working at 1 year and 1 month. Technically out of warranty by a month, which is unfortunate. I reached out to the seller/manufacturer about a potential warranty, and they graciously agreed. Communication was very slow, but they took care of me.in the long-run.

Used for about 2 weeks, so cannot comment on longevity (but will update review later). User manual is thorough and accurate (which is rare!). I can confirm the listed DC voltage alarms and limits. The no load power draw for my unit was 0.8A. Waveform is clean on oscilloscope. Solid construction. Seller is helpful and responsive to questions. Overall, an excellent product! Some comments: - Internally, there are 4 x 30A automotive spade fuses to protect the DC side. I still added an external fuse on the positive battery terminal, but theoretically, you wouldn't need to. - The provided battery wires are probably fine for most cases, but a bit small gauge for my liking, so I created my own using 2/0 I had. Thankfully, the terminals on this inverter can accept very large barrel lugs. - The remote panel works well but design could be improved. First, it uses a RJ10 ended (4P4C) cable which is not very common (I needed a 50ft long cable and had to make it). The panel fits a 86mm x 86mm box which is also not common in North America. Finally, I wish it reported the voltage instead of 4 LED lights.

This product is excellent and provides clean AC power to sensitive electronics, TV and computers, routers etc. We recently had a power outage and I was running TV, computers, wireless routers, fiber modems without issue. The DC battery load current is not trivial. In my case I had two 12V marine batteries in parallel and could power 500 watts without a problem for about 6-8 hours. On a separate occasion, I hooked it up to my Log splitter which is rated below 1500 watts however the current draw from the battery would result in Low voltage disconnect. In high power applications such as a log splitter, you would need several batteries in parallel so that the disconnect voltage trip does not occur. After buying this product, I'm unsure if I will ever have an instance where I will draw 1500W continuous. So having realized this I could have considered buying a smaller 1000W device. I'm still very happy with this product and would recommend it to anyone who does have a need to provide 1500w. Do your homework and make sure you can draw close to 200 amperes at 10-12 volts if you plan on drawing this power.

Très très satisfaite un peu gros mais pas grave. Et en plus branché sur une batterie au lithium, l’écran nous dit combien il reste de mémoire de courant

Excellent, very happy with this product.

The unit works great so far. No issues yet. Be cautious of the power requirements of whatever you are looking to run, though. Check the wattage and make sure that the unit won't be overloaded. It does have safety factors built in, but you will be disappointed if you think it can just run anything you plug into it. I only needed 2000w and it works great for that, but I have no plans on pushing that limit. Also, the inverter does not come with power cables long enough to perform most installations I've ever seen. I had to buy extra wire and connectors, but it wasn't that difficult to find what I needed and get it installed. Just some advice, don't buy cheap wire either. It's not worth the problems it could cause. Still a great deal for the quality of unit in my opinion.
