4000 Watt Pure Sine Wave Power Inverter 24V DC to 110V 120V Converter for Family RV Off Grid Solar System Car with Type-C Ports 4 AC Power Outlets Dual USB Ports LCD Display and Remote Control

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.

Great product. No issues. Just running. It's my second one I installed with another solar system.

I'm running my apartment sized refrigerator / freezer and everything else in my house, swamp cooler, 1100-watt microwave, etc. Everything except 20-gallon water heater and shallow well pump. It's looking very promising at this point as it has performed flawlessly with everything I've plugged into it!Thanks, JARXIOKE!I'm buying another one soon! What a pleasure to find a company that still builds a quality product at a very reasonable price and delivers what they advertise! 5 STARSOne month use update... This little inverter just keeps on amazing me! I'm so impressed I just bought another one! Connected it to the Bus Bar this morning and plugged a box fan in for initial test run.All is A-OK! This inverter will be a side by side set up with one inverter powering most of the house, and the 2nd one just wired to the 20-gallon 2000-watt Hot Water heater and Irrigation pump for the Orchard / garden area. Now all I need is #3 for a back up!PS please don't buy them all so availability will not run dry.One Happy Camper!

This inverter has been in use for the better part of a year as the heart of my offgrid solar system. I found I needed to convert from a 12V battery configuration to 24V at short notice very late into my build budget, so this was a compromise to the mid-grade (Renogy) or premium (Victron) pure-sine inverters I might have otherwise gone with in the outset.It's handled everything I've thrown at it, including a 14k BTU heatpump, medium sized fridge, 1600W microwave, 1800W dual hob induction cooktop, lights, fans, pumps, security system, internet, weather station, 2 LCD tvs, stereos and a gamut of chargers ranging from phones and laptops to heavy cordless drill and ebike battery packs.I have a few caveats though... Good for another prospective buyer to know:Number 1: The biggest issue being the output frequency... Despite the very deliberate assurance on the otherwise informatory LCD screen (pictured), it's putting out about 61~62hz.While in most cases, this is not a big deal, it does cause straight AC motors to turn inegligibly faster than they would while plugged into your house's 60hz outlet.It hasn't had any noticeable impact on my fridge, and the heat-pump system (a Midea Duo) doesn't care anyway, since it has its own inverter driver for infinite speed control to its pump.I first noticed the symptoms of this flaw when my trusty old red bedside LCD alarm clock immediately began gaining an entire minute per hour, and just over 25 minutes pretty day) when I upgraded from my previous 3000kw 12v Renogy, which had a stable 60hz output by contrast.I initially assumed the clock had crossed the rainbow bridge (it was a cheapo when new, which was a little over 20 years ago) until I decided to set the clock on my brand new microwave oven, and it ran fast at exactly the same rate. BUSTED! I didn't even need a meter to tell me the freq was just running high.Oh well... It was a small enough disbelief discrepancy that I decided to just run with it as-is, so I bought a USB powered alarm clock to replace it (those have to use an internally synthesized clock-time using its own internal chrystal chip instead of line frequency) and I just keep the microwave clock blank instead of setting it. My meals cook 1 to 5 seconds short depending on how many minutes I input; not a big deal.Number 2: The PRO here is that they provide replacement automotive blade fuses; the CON is that, not only do you have to open up the case to replace them, but they're not even socketed... you have to solder them in. This blew my mind.Hopefully they improve this amateurish design issue in subsequent revisions.Number 3: It comes with a handheld remote to be able to turn it on and off without direct access. It's a nice touch, but you have to buy the battery separately... They won't provide it with the remote.Not a big deal, just a minor gripe. It's not a feature I would personally use anyway, so I'm not concerned... other buyers might care though.Number 4: This isn't an issue for me but it's still something that's good to know before ordering: Manufacturer strongly suggests horizontal mounting of this unit. Depending on where and how you plan to mount it, the built in display may be difficult or awkward to read. Easy to see if it's mounted flat on a shelf of viewable height, but at floor level, or on a wall with the required horizontal orientation (which is how I have mine mounted) it can be awkward.One pro that I feel compelled to mention here: A lot of other buyers have criticized the fan speed on this unit, saying that it's not automatically variable in speed for quietness. Well they're only barely right.... it IS a variable speed fan which comes on when needed and shuts off when not. Spend enough time living with this inverter, and you'll notice the differences in speed, dictated by load/temp.I believe a lot of these people are complaining because they expected the cooling system to be silent, and it most certainly isn't. The sound the fan makes is noticeable, but not any louder than one should expect, so I'm fine with the unit keeping itself comfy while it works tirelessly for me.This inverter will eventually be replaced (by a Victron, most likely) and I'll keep this as a backup.It's been reliably providing me fulltime power with no breaks for the better part of a year, without falter. It even shuts itself down when duty load is exceeded for too long (it beeps a warning, as it permits the temporary draw of >4k-8kw peak, for momentary motor startups and such) and then shuts down..... then after a brief timeout, she starts back up again without me having to do anything, so I have personally never had to replace a fuse inside it (thank God). This has only happened when I stupidly overtaxed it, like turning on the microwave while something is on the stove at full wattage, with my AC kicking at full tilt, which came to around 4600-5000 watts, and I didn't correct myself quickly enough when its warning beeps began. That's operator error, and the inverter handled its business well.This unit has been worth every penny, so I recommend it as a big bang for your buck.

I bought this back in July 2024, so it been almost six months. So far it is definitely doing its job. I haven't pushed it past it normal 4000 watts, it says it can take a 8000 watt spike. I live in my RV full time though so it see a lot of usage and it hasn't slipped up yet. I've run my 1500w air fryer, 400w rice cooker, my gaming PC, and a mini fridge. As well as some small chargers and stuff. It handles it all just fine. Fan comes on mostly on for big inductive loads, like the air fryer. Not too loud, but noticeable. I have it in the living area in the under bench storage.
