500 Watt Pure Sine Wave Power Inverter 12V DC to 110V 120V Converter for Home, RV and Off-Grid Solar Systems with Type-C Port, 2 AC Outlets, 2 USB Ports, LCD Display

I have their matching 500W inverter also, and other than a larger size and remote control, this one is the same. Informative accurate display, heavy enough input wires to carry the expected load, fan only comes on under high-ish loads. By no means silent but it will do the job with no drama. I'm using it to tap the vehicle alternator/battery and drive a high-current LiFePO4 charger (Capacity.Li item B0B67S5R6D) that has an output current knob for either gentle or fast charging. Don't use long wires at these current levels!

This is an amazing little unit considering the price. I’ve pushed it to 1150 watts continuous and it handled that with no problems. The sine wave is clean and the voltage level holds steady. It does need enough battery to provide 90 or so amps without the input voltage sagging, so don’t hook it up to a small battery and expect it to perform to specs. The fan keeps it cool enough but it is loud. I have no use for the remote so I haven’t bothered with it. I’ve installed it in a van with dual 70ah batteries, and it easily charges my Jackery and the house batteries while I drive. If I keep the load to less than 400w, the fan doesn’t kick on and it’s completely silent. The thumb nuts will loosen over time, so I added a lock washer and that fixed that issue. Also, the cables that came with the unit seemed undersized, so I doubled up on those. I’m very pleased with it so far

First, to the reviewer dissing this unit because it didn't provide the full 2500W from a single plug. The chart above will help explain to you WHY no unit in this class will EVER do that. The plug in the top right is the normal plug for US homes and is also the plug pretty much EVERY inverter in this class offers. It's a 15A circuit (same as your house). It's the plug used in THIS inverter. That means from each plug you can only draw 1800W MAX (15A X 120V = 1800W) from each plug. In the middle on the left side is a 20 amp socket. Notice that one side has a t-slot. That tells you it's a 20A circuit. Now a 20A circuit would get you CLOSE to 2500W, but not quite (20A x 120v = 2400W). This is NOT the socket used on this inverter. On to the actual review of this unit. It's a super simple install with the included cables. I can't speak to the quality of the cables. They seem large enough and I hope they are real copper rather than copper claded aluminum. They do have nice ring terminals on each end that seem to be crimped on well. Also, all four ends have NO actual wire showing, just the rings. The unit itself has a nice heft. The small display on the front has all the important info. One place I've noticed that Chinese electronics fall down is where the cables connect. Usually they are flimsy and ill fitting. On this unit the connection is well though out, solid and completely insulated. For power I use a 250Ah LiFePo4 battery with a 200A BMS which can supply everything the inverter can draw. So for a test I put my house fridge (700A), chest freezer (600W), Desk top computer (300A), 4 monitors (about 150W total) for a total of a little over 1700W on one plug. Remember, the MAX available if you're ac is 120v (not 110v or 115v). I had everything set up to power on immediately, so big draw as soon as you start. Everything powered up and ran just like they were plugged into separate wall circuits. The twin fans do ramp up with temperature and are NOT the quietest fans in the world. But that's sort of a function of their size. Small fans have to spin faster to send the same amount of air as a bigger fan. At full chat they aren't hugely annoying, but you WILL hear them. You probably don't want them in the living room or right next to you at a campsite. The unit offers 3 120vac plugs on three separate 15A circuits. I would've liked to see individual replaceable fuses for each but instead there is only a single 40A fuse for the entire thing. They do give you 6 spares though. I LOVE the remote. Some units give you a wired remote with a display and an on/off button. And this is great if you're going to MOUNT the remote display somewhere. But my system is on a cart to be wheeled to where it's needed. So that wired remote would be of NO use to me. However, the on/off function of the wireless remote is great for me. I can turn the inverter on and off from wherever I am (within 100'). Simple. One thing to note though is that no bsattery is provided with the remote and it uses a somewhat esoteric A23 size. Not a big problem, but something to know. So far I'm really liking this unit. It does would could REALISTICALLY be expected of it.

Bought 24v 4,000W version. I purchased this because I wanted to go as big as I could with my small solar array. I have a 1 HP well pump, a plug-in hybrid vehicle, and some outbuildings that need fans/lights. I've run this inverter for almost a year, and it has performed great, even in the hot summer. I regularly run the well pump while charging the car (level 1 charger, 14 amps) and it's no problem. I also run a clothes washer at times so we can wash clothes and pump water on green power. What I like most about this inverter are the following: 1. Power is clean. It's just as good as street power. 2. The inverter is compact. For the wattage, this was the most-compact inverter I found on Amazon at 24. 3. It is thoughtfully designed. The display, lugs, and plugs are all at one end and easily read and accessible in my enclosure (it is mounted, along with the charge controllers, breakers, etc. in a weatherproof panel). The 24V connections at the other end are laid-out to easily attach the provided cables, which are of a configuration and size that they take up as little room as possible. The lugs allow me to have a 30A main circuit to my 110V breaker box, giving me the ability to run multiple 20A circuits from there. 4. It stays cool with the included fans, which really don't run that hard unless I'm really drawing a lot of current. Given that it's in an enclosure out at my array, I never even hear it. Fantastic product, I will probably buy another one if I can support it with an array expansion. Update: been running the inverter for about a year and a half and while it still performs all of its functions well, the voltage dips a bit more than it used to as I’ve been running it more heavily loaded. Where it used to recover to 120v, it now maxes out at 115v. This hasn’t affected operation for the most part, but I’m not sure why it’s doing this. In addition, the power estimate seems to be way off (by about 20%) versus volts and the amps I’m measuring when it’s running. Reads high, which is better than low, but still a bit strange. It has a difficult time handling surge. When it’s putting out 2,000 watts and has to start the well pump, even though the surge isn’t really very high according to my amp meter, it can overload from time to time. Not sure I really believe the 8,000W surge claim. It would be nice if they gave more information, like the rated duration of surge wattage at various levels. I’d probably buy it again, because as a form factor, the overall performance, and with the accessories it comes with, it’s not a bad deal. I just wish it was a bit more robust with respect to the output voltage after a year and a half of run time and that it would surge what it says it will. Also, that the wattage on the display was a bit more reliable. Still a good experience overall, and you shouldn’t have any doubts about buying this inverter.

Works well , will be very handy for camping where there are no services .

J'ai acheté ce petit onduleur 500 W. Tension de 120 V à la sortie avec onde sinusoïdale pure. L'écran sur le dessus fourni toutes les informations pertinentes, tension d'entrée, de sortie, puissance, etc ce qui excellent. Le ventilateur ne fonctionne que lorsque la puissance demandée est de plus de 200 W de sorte qu'à faible charge ou à vide, il est très silencieux. Pour terminer, il est équipé d'un démarreur à tension réduite "soft start" de sorte qu'il réduit la puissance demandée lors des démarrages de petits moteurs. Il ne manquerait qu'une protection DDFT pour être complet. Je suis très satisfait.

Inverter is bit noisy when the fan runs, I did not keep it as I have a 1000w which is quieter. It is a good product though.
