2000W Peak 6000W Pure Sine Wave Power Inverter Charger DC 12V to 120V AC Output Converter with LCD Display, Off Grid Low-Frequency Inverter for Sealed Gel AGM Flooded Lithium Battery Charger…

UPDATE: Changing from 3 star to 5 star. After working with the seller, they suggested that the hot and neutral could be reversed at the AC input to the unit. I didn't think so, but I checked the input and I had correctly wired the black lead to "Load" and the white lead to "Neutral". However, after disconnecting the AC cord I used, and testing it, turns out it was wired with the black wire going to the neutral side of the plug, and the white wire going to the hot side. Reversed the inputs and all was good. Taught me a lesson: always test EVERYTHING when wiring up circuits.Like several others that have reviewed this product, I found that the hot and neutral were reversed at the AC outlet plugs on the unit. This was verified with an AC tester. However, it's more complicated than just reversing the hot and neutral at the AC outputs. That's because when the unit is on AC house power, yes, the outlets show a hot/neutral reverse. But when you kill the AC power to the unit, and run off the battery/inverter, the output at the AC outlets is correct, with the tester showing no issues. So in my opinion, if you reverse the hot and neutral at the outputs your AC tester will show everything good when the unit has AC to it, but when you have to run off the battery, it will now show a hot/neutral reverse. Not sure what to do about it, therefore only 3 stars.

The media could not be loaded. Using for an off grid cabin. I tested the inverter at home connected to110 house current attached to a Lifepo4 battery. I found the 2 outlet plugs were reversed for the hot and neutral. There were no instructions for the use of the different modes. On line documentation is very limited. Brought the inverter up to my off grid cabin and tried to connect it to a generator. It would not work, the inverter kept recycling from charge to not charging, tried using all the different modes. Emailed the company with the issue and videos of how the inverter was acting. They responded and said to use the generator mode, which I did. still the same results. Again I sent them the results, that's when the communication on there part stopped. Emailed them and the seller on the results with the email communication trail and requested how to return the unit. No response.. Contacted Amazon, went through there tech support, still did not work. Amazon would take the return but since it was past 3 months would only give ne 80% of what I paid for it, even though the inverter did not function properly.

The power inverter stop working with a battery low error/alarm. Contacted support but no answer yet. Hopefully I get a response soon with a resolution. THE 5 STAR IS FOR VISIBILITY ONLY.Update: The seller sent a replacement unit without any extra charges.

Worked for a year. Only used it maybe 6 times. Other reviews had same issue.

I installed the inverter on my camper. My intention was to power small items and microwave, and if I needed to run my Air conditioner, I would use the line power or generator mode.When I was connected in line mode and ran the air conditioner the inverter showed running at 90%-100% and was getting AC overload faults. I expected when using priority line mode, I expected the inverter to bypass the power, but it wouldn't.Customer support is in China. They offer support through email, or you can call them through WhatsApp. I called them during their workday (+16 PST) I could never get an answer. I sent an email and got a response. The tech indicated it shouldn't be doing that. I requested an exchange, but never got a response. I sent about 10 other email but no response on any of them. Fortunately Amazon accepted my return. The user guide has no detail or answers to questions. The Ampinvt website has no trouble-shooting information. There are no videos online. If you have an issue with this inverter. Don't expect much from the company.

I installed this in my school bus conversion and am very pleased with its performance so far. I love how I can hook up everything I need on the 12 volt poles (batteries and loads), hook up 120 volt AC loads on the other side, plug in 120 volt AC from grid power, and this inverter charter keeps track of everything and automatically knows what to do in order to keep the loads going and the battery voltage in acceptable ranges. I even set up a 4-way isolater switch on the 12 volt side to let me select between the bus starter batteries, the lithium phosphate "house batteries", both battery banks at once, or neither bank. When plugged into grid power, I can decide which battery bank I want the inverter to charge. Also, because the bus alternator is wired to the starter batteries, I can set the switch to "1+2" and have the bus engine charging all batteries as well as supplying power to the inverter, which can be used to power the 120 volt AC gear I have in the bus.This inverter has been able to power a 12,000 BTU mini-split air conditioner, a 13 cubit foot refrigerator, and various handheld power tools. It only beeps at me if I am running more than two of these things at once.Overall, I love having the charger integrated. I love how this unit does so much and has a lot of modes and options for being in different situations on the road or camped out. Five stars all day long.
