Works great, this is my second only because I screwed up and fried the first one. Put in some safeguards to protect this one. Installed it in my 20' enclosed trailer/toy hauler that I built out. I have 600 watts of solar so far and 942 ah of lithium battery storage. This combination of 942 ah of storage and 3000W inverter runs my AC, TV and lights all at once. Haven't run a long enough test yet to see how long it will last. I did try a 3000W Renogy but it wouldn't stay on, every time I flipped the switch to power the trailer it would shut off. The GFCI settings were set too sensitive and couldn't handle the load. So don't buy Renogy, get a Giandel you'll be much happier.

I bought a 600w inverter from these people. It has completely failed. They don't want to return my email's. Maybe this review will help.

Un-installed a working inverter connected this one and it won't turn on...

Upgraded from 1000 that we previously owned. Haven't put this one to the test yet but we were very happy with ease of installation and quietness of this brand. Only thing to keep in mind is to go with better wire

I use this in my work truck to power my starlink system and it works like a charm!

I used this as the output of a portable power center that I keep in the back of my truck when I am traveling with a camper, so I have shore power even when boondocking (and thus don't need a generator).The gauge is nice. It at least reads the voltage accurately, though I haven't verified the other readings. On mine, when you first turn it on, it has no draw, but if you put a load on it and then remove that load, it still draws over an amp. For me, this isn't a problem.It has a decent efficiency, is pure sine wave, and is plenty large enough to run an entire camper. It has off-grid hookups, so I could easily wire up a 30A RV plug for it. The remote is nice since I can leave it in the back of the truck, and still turn it on/off without crawling into the bed. It is one of the most full-featured units on the market, and one of the largest.The included wires felt laughably inadequate for 4KW (the rest of the power bank is using 4/0 welding/battery wire, and this came with 2 pairs of what looks like either 2 or 4 awg wire) so I upgraded the wiring. It is an expensive unit, and I will probably never come close to 4KW of load, but it is good to know I have the headroom if I get a larger camper in the future.

Inverter is awesome not a problem with it excellent buy for the money you pay. It's well worth it good quality unit 100% I'm running a 60 amp mppt with this unit and 5 100 watt solar panels all connected parallel. This unit can handle another 60 amp mppt which I'm going to connect so I will have to and also I will be capable of running 18 100 watt solar panels . I am running for deep cycle 235 amp hour 6 volt batteries at the moment I am going to add four more what should be more than sufficient. This 3000 watt pure shine wave inverter is more than enough to handle what I'm about to add to it on top of what I already have very happy with the product.

Unit Purchased= 4000 watt. Usage for RV/ 5th wheel travel power.Received thru Amazon two days after purchase in good shape but missing remoteReceived missing remote three days after customer support contacted me.Pros:Works as rated. My plans are to use it for my 5th wheel travel power. I got the unit and tested it to see if it would handle the load before installing in my 5th wheel. I put it on four 300amp AGM lifetime batteries using two strands of 4/0 wire for both pos/neg(the four 8 gauge wires provided were too short and did heat up on heavy usage).. Tested with two 1500 watt heaters for 3200 watt load and worked great for about two hours before it took the batteries down to half load and below 10 volts so auto shut off. Recharged batteries and then did second test by adding one more 1500 watt heater (3x) and still work. Went into overload of 6200 watts on startup and then down to 4200 watts and still worked great until the batteries were discharged below 10 volts then auto shut off.The unit does suck power, but provides the power needed. I then tested it on an RV refrigerator and a microwave. No unusual sounds or issues and provided the needed power. I have not tested the pure sine wave power yet but using it on motors and heaters has not been an issue.The unit is good sized (generally=length about the size of average mans chest and half the width so it is rather big, but can easily be installed inside a 5th wheel front storage compartment.The remote switch works great.Con which turned into a pro: My unit originally came with NO REMOTE. The company actually contacted me thru Amazon e-mail and asked if I got the unit and how it was working. I advised Elsa (Customer Support) that I got NO REMOTE and she sent me one three days later. Excellent customer support. Unit works as advertised and excellent customer support.Update - (02/10/2019) - I have not installed it in my RV yet but as an electrician, I tested it for pure sine wave power and it meets specs. I've had no issues for powering my computers and sensitive electronic components. However, this unit will pull over 600amps (12 volt) on full power usage so I would highly recommend users greatly upgraded their wiring and also use multiple stands of heavy gauge wire. I elected to use 4/0 wire and used three strands as I had extra wire left over from another solar project (two strands 4/0 works fine too). The larger the wire, the better and the more strands, the better. This unit will pull lots of amps.
