I installed this pure sine wave inverter/charger to replace an old UPS battery backup for my modem, WiFi, and switch. The old UPS backup would only last for 30 minutes. If the power was out for any longer I was out of luck. My system includes a 100 AH LiFePO4 battery and should last for about 3 days. The charger lets me take advantage of my solar power to charge the battery. I cycle the battery by disconnecting the unit from the AC supply for 15-30 minutes every month. Be sure to cycle the system before using it. This will charge the units capacitor and prevent a momentary power interruption as described by other reviewers. So far so good, will see what happens this hurricane season.

I bought this to replace my 15-year-old ultimate power 1000 watt inverter / battery charger I've been using in my work truck.

So far, it seems pretty good although I'm not sure if it float charges or if it always supplies full voltage once the battery is full I'll update once I know. I didn't see anything in the settings about float charge though.

I was kind of nervous buying this as there aren't a lot of reviews and the reviews that are there are from people who got the product for free to test it. This is only day one but if anything changes I'll be sure to update.

I don't really run a lot out of the inverter, a microwave a couple times a week for a couple minutes each time and a fridge in the summertime. I have a port on the side of my truck to attach an extension cord to charge aux battery at night.

I was hoping I'd just be able to keep it on eco mode and leave the inverter on all the time for the fridge in the summertime which I should be able to since I'll have to wait most of the time but if you don't really have any load all the time be warned. The Eco mode is supposed to turn the inverter on when there's more than 5% load. To do this it seems like it pulses every 20 seconds or so to check and see if there's a load applied. So if you plug something in it's not going to turn on right away, you'll have to wait a few seconds for the inverter to pulse and see if there's load and once it recognizes the load it'll stay on.

In eco mode with no load applied the inverter pulls 10 watts at 12 volts, when it pulses it pulls 25 watts at 12 volts. When you apply AC input in it automatically transfers your load to your AC input.

There are also no measurements (that I could find) on the listing so I figured I'd provide some for everybody. 19x12x8 inches roughly rounding up.

Fans kick on automatically when there's load applied to the inverter so that's cool and should help it stay cool. Hoping this last a while. If I don't update this post it's still kicking

This 2000W in inverter is a hefty unit compared to other 2000W inverters I have experience with. It's physically bigger and heavier. However, this is the first that I have used that is bi-directional. That is, it charges your battery when plugged into line power and seamlessly supplies ac power in inverter mode when AC input is disrupted. The manual supplied is for all models of various battery voltages ranging from 12 to 96 volts but do not be mislead. This is a 12V inverter only. Other models will handle higher dedicated battery voltages. I noticed some in-rush current when I first connected the battery. It arced when I connected the terminal. However, I measured (with a multimeter) no power draw from the battery when the unit is off after that first connection. The first time I pulled the AC input, the AC output blinked but thereafter it did not with subsequent AC input disruptions. Overall, it seems to be a solid inverter for the price and functionality.

Even the packaging was impressive. The best cardboard box I've ever seen.

I hooked this up to my crane battery power for testing. After learning to hold the on button a few seconds it was up and running. Setup was easy to understand and everything was well labeled.

There are 5 modes of operation. We used the default A/C priority. It began inverting right away. Tool operation was very smooth. That's what I love about sine wave inverters. They won't burn up your tools like square wave inverters. Believe me, I learned the hard way.

I used a multitool to test the power. It was only about a 13% load per the meter. I switched the generator on and it swapped over to the generator powering the tool and charging the batteries. Turning it back off it went right back to inverting.

My experience with these inverters and charge controllers made in China has been very good. I see other sizes of inverter from this company rated as top and that agrees with my findings.

There is an on board battery charger too that will pull up to 35 amps. This inverter has it all. I'm impressed.

I'm sure this will power my auxiliary power supply just fine.

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.
