I purchased the 3000 watt inverter and hooked them up to two lithium batteries and was able to run a 1500 watt toaster for 5 minutes, then a 1500 watt convection microwave for about 5, a 12k BTU air conditioner for 30 minutes (struggled to start but worked), and assorted other smaller items. The batteries were still over 82% by the time I was done. While running the air conditioner the two fans on the side of the inverter did turn off and on several times but don't make much noise but they do push a lot of air. I am impressed with the unit. The front panel show the battery voltage and the AC output voltage. I good unit so far, I would buy one again.
UPDATE: I have found that I was having a power drain when the converter is shut off. I found the converter takes power when it is switched off. I seem to have about a .68 amp constant draw from the converter, I plan to remedy this using a circuit breaker with a throw switch. When I switch the converter on with no load it uses a approximately 2.65 amps. I didn't realize it would use that amount of power idling, but I am not a professional on this equipment! I still like the converter.
I bought this as an upgrade for my tiny solar system. My old modified sine inverter died and I replaced it with this. I decided to go to 3000 watt so I would never have to use 100% capacity. I believe over sizing the system for your demands is the key to long term operation without failures. This seems to be especially true with solar systems. The manual that comes with this inverter even says, "Better to use 80% of the rated power of the power inverter for longevity of the power inverter." It's a good manual. Read the pdf before you buy and you won't be disappointed.
The order shipped quickly, arrived in excellent shape, the unit is clean and looks high quality. I read the manual, hooked up my (2 golf cart 6 volt in series) batteries and turned the unit on. The displays lit up with battery voltage and output voltage and matched what I measured with my old Radio Shack meter. Good show so far. I then successfully connected and ran a battery charger for my hedge shears, an old Craftsman shop vac, and then a K-cup coffee maker. I am happy to report all worked fine. My maximum load was the coffee maker at a rated 900 watts. Output voltage stayed between 120 and 122 VAC for the entire run of the cup of coffee. However, the battery voltage fluctuated from 14 down to 10.9 and then back to 13.2 at the end of coffee production. I have #0 AWG wire connecting my batteries and the inverter because 12 volts needs so much current to run the inverter. So far I am very happy with my Yueqing Reliable Electric 3000 watt, 12 volt pure sine inverter.
Make sure your battery connection is tight, hehe, hums away, powered my ps4 and big tv on it. I really appreciated the volt meter on the battery. Held out at 11.99 and 12.01 volts pretty well and a consistent 120volts when everything was tight.
Inverter seems to work well. I had a question for tech support, they went out of their way to answer a long series of questions via email. Excellent tech service.

I use this 3000W 24V inverter to charge my Chevy Volt car. I have 6 370W Silfab PV panels, 2 40A EPEVER charge controllers, and (12) 6V batteries set up as (3) 24V strings. The panels charge the batteries all day, and I dump all that battery juice into the car using the inverter. I have had many other devices hooked up to the inverter, all worked fine...most often the chest freezer in the garage. My Volt car charger is 120V and runs at about 1500W and 8A. If I set the car mode to heavier charging it runs about 1800W at 12A over the 120V. I do not own a 240V charger.
The car takes anywhere from 8 - 12 hours to fully charge.
My batteries will not charge the car completely, so it will empty my 12 lead acid batteries over 6-8 hours. The inverter powers through this every day and shuts off before the batteries are drained past the safety level. Had the system running almost 6 months. This inverter can handle the car, freezer, and some other small loads all at the same time. My only complaint is the fans are a bit loud. Since this is in my garage it has little impact.
Works great. I can run microwave and Keurig coffee maker while not even starting its cooling fans.

The inverter has been in almost daily operation for about a month now and works great on my frost-less freezer.
Highly recommended. ..thanx
