Renogy 700W Pure Sine Wave Inverter 12V DC to 120V AC Converter for Home, RV, Truck, Off-Grid Solar Power Inverter 12V to 110V with Built-in 5V/2.1A USB Port, AC Hardwire Port, Remote Controller

El inversor llegó desde el día 1 de diciembre pero no fue hasta hoy 16 de diciembre que tuve Chanza de ir a instalarlo. Y no prende para nada lo compre aquí según la calidad y estuvo al revés.

Update: I originally left a 1 star, not for the device, but more for the resale, I thought this second one was faulty, turns out one of my bus bars was faulty, this was TOTALLY MY FAULT (maybe the bus bar as well). Renogy got back with me even though this was a resale and informed me it’s not under warranty but still offered tips on what to do. I’m happy that this worked out because I really like this Renogy company and eco system. Looking forward to upgrades, future builds and all. I left the original review for context belowI would say this is more of an Amazon resale review as this is the second unit I bought from resale that is DOA. This first one never worked, figured was just a bad unit, 2nd one sparked so hard it left a groove in my bat terminal and now won’t accept a charge from my charge controller. I don’t know what the process is on testing these with Amazon resale but they definitely were bad. I don’t know how Renogy would let you all re-sell bad units, looks bad on them

I've had great luck with Renogy products. This one is no exception. We installed this in our camper. It will run a medium refrigerator just fine.

I originally bought this inverter a few years ago and have been using it in a camper that has a ~12v, 4s 280Ah LiFePO4 battery in it. It was able to start and run my 5000 BTU Air Conditioner without issue.I picked Renogy because I figured they had some better engineering than the typical generic branded inverters around. They also list wattage as true wattage and not peak so I appreciate the honest marketing.Recently, I pulled about 675w AC through the inverter for about 4-5 hours (was checking battery capacity). I put a 70A ANL fuse on the positive wire between the battery and the inverter. I was pulling about 65A DC the whole time.A day later I was running 200w AC (about 20A DC) through the inverter for maybe an hour. It turned off and wouldn't power back on. No lights, no beeping, nothing.The external 70A ANL fuse was fine.Took the inverter apart, and it turns out they used 4 mini automotive 25A fuses in parallel soldered to the PCB. The fact that these are soldered and in parallel means they were more interested in cost cutting vs proper design and engineering. The issue with parallel fuses is that they don't always share the load equally, and in this case one or two of them probably blew, which caused the rest go with it. There is a large copper plate acting as a heatsink soldered next to these fuses so they were clearly concerned about the heat these fuses generate. That is likely why they opted to solder vs use a holder, so they would have decreased connection resistance. However, a simple bolted MIDI fuse would have been about the same cost, more reliable and more easily user replaceable.Searching the reviews here and seeing others having this issue just confirms the poor engineering of this premium-priced product.These 4x 25A fuses in parallel are, on paper, supposed to be able to handle 100A, yet the 70A external fuse didn't blow while these did. That fact only serves to further reinforces the issue.I was able to replace the fuses and it works again, so nothing internally, like the mosfets, shorted out to cause this. Was simply a poorly designed fuse issue. Since I have an external fuse, I may just solder bridge this and rely on that fuse vs these internal fuses.If I were to do this over again, I'd just go with a generic model at a fraction of the cost. Renogy isn't adding any value here for the price they are charging. I have similar complaints about their DC to DC converter, but that's another topic. I'd also highly recommend a higher voltage DC system if you are going to need more than 700-1000w AC in your system. The thick cabling, heat and fuses issues that come with the really high currents of a 12v system are just not worth it. 24v or even 48v would be much better if you need a lot of AC power.

I purchased a Renogy 700 W Pure Sine Wave inverter because I thought it might be important to have a pure sine wave inverter, as opposed to a "modified sine wave" (which is actually a square wave) inverter.I don't really need 700 W, it's just for charging/powering a 60 W laptop, but I figured that the extra power would make the fan less likely to turn on.It's important to me to have a quiet inverter, because a primary reason for going out of the city is to enjoy the quiet surroundings.All of the reviews seemed to indicate that this inverter is either quiet or totally silent. However, when I tested it in my living room, with a 60 W incandescent light bulb, after thirty minutes or an hour the fan came on. I think this was just a result of me using a heater nearby; the room temperature was about 70 degrees F (if I use an inverter in the desert, it will be much hotter).I'm sending this one back, and posting this review with a recording I made of the fan, and a picture of the audio spectrum. In the spectrum you can see there are a large number of different tones and harmonics, as well as some interesting stuff at 10 kHz. For reference, the sound of rainfall, which is called "pink noise", would be a flat horizontal line on this plot. I think companies like Apple put a lot of work into making fans that are not only quiet, but sound like broad-spectrum noise when they operate. This fan sounds like some kind of sci-fi weapon or maybe the machine room of an alien spaceship.It might be useful for someone with an RV, where the inverter is going to be in a closet. I could not imagine using it near a tent. I'm going back to the Bestek 500 W Modified Sine Wave Inverter which I had purchased earlier. Although the Bestek has a noisy fan as well, it is far quieter than Renogy's. And apparently most laptop chargers are OK with a "modified sine wave" inverter.Other things I didn't like - the Renogy beeps too much. It beeps when the battery is low, which may be useful, but it also beeps when you turn it on, which seems unnecessary. The Bestek comes with battery clips and a cigarette lighter attachment, making it portable and versatile; the Renogy comes with cables that only have ring terminals on each end, and must be bolted to a battery. To be fair, my car cigarette lighter socket can only produce 180 W max because of the fuse; and I may end up making ring terminals for my Bestek, to get better contact. Just keep in mind that the Renogy is designed for more of a permanent installation; it's not going to be sitting on the passenger seat while you drive.
