OLTEANP New Upgraded 3000 Watts Pure Sine Wave Inverter, 12V DC to 110V AC Power Inverter with 4 AC Outlets, USB Port, Type-C Port for Truck, Vehicle, Power Outage, Remote Control with LCD Screen

Wow I'm impressed, this will run a real 7 1/4" Skilsaw, has plenty of reserve to start a real construction Skilsaw at 1,800 watts start up, and up to1,000 watts at constant. Also will run any 120v compressor. I'm using a 200ah lifepo4 12v battery. This inverter Would have no problem also running table saws and chop saws. Everything within 2,200 watts AC 120v will run efficient. But you will need a much bigger battery bank if you want to run say a 1,500 watts AC for any length of time, more amp hour batteries will give you longer run times. I like the low voltage cut off settings you can set so you don't over drain your batteries. Nice feature and absolutely necessary. One thing I noticed, that the fans rarely come on. And they only run for a very short time. I was pulling 1,200 watts for awhile and no fans came on. This thing runs much cooler than my other brand 1,000 watt inverter, which shows this inverter is both effective and efficient. If You need more than 2,200 watts constant you should bump up to 24 volt DC batteries and a higher wattage 24v DC input inverter. Way more expensive, but you get twice the juice out of a 24v battery than a 12v battery and only using half the amps of 12v battery. Twice effecient over 12v. The AC voltage on this inverter stays high around 119v/120v AC. Which is correct AC voltage. Most Inverters run at 110v to 115v AC. Then they drop down more in AC voltage under high loads. Not good, but this inverter is good and always stays at least at 118v to 120v AC even under load. Higher voltage means better speeds and performance on AC motors and fans. This will also able to run 120v full size fridges, window AC unit or split AC, Skilsaw, wet dry vacuums, carpet vacuums, Carpet cleaning machines, air compressor etc. But Stay at the Maximum of 2,200 watts constant load, don't overload it. The max load constant of 2,200 watts dictates how many devices you can run on this inverter at the same time. Again Don't overload any inverter. Bad for batteries and wears out the inverter. This inverter has a quick surge capability of 4,400 watts. But only a few seconds, only for power surge start up on AC motors. But this can run constantly at 2,200 watts AC. Most people will be happy with this inverter, and it will run many of their AC appliances. Looks well made, with nicest remote display turn on off I've seen. Display is fairly accurate. We'll see if this inverter brand holds up, if it does I'm buying this brand from now on.

I love this thing. Strong output. If you want/ really need 120 output volts, this is your answer. Built well. I really like the remote and its informative readout. Reliable inverter. It ran 24 hours a day at Burning Man this year for 12 days straight, though high winds, dust, lot’s of dust, rain and extreme heat without skipping a beat. It ran a full size freezer the entire time with no issues.

Test results so far have been excellent. I will soon be installing the OLTEANP 2500w to run our 1990s GE refrigerator, using 800w of PV, and a 2.10kwh NMC 50vdc (golf-cart) battery. The refrigerator 120AC power will auto-switch to grid power, when there is no solar or battery power (too cloudy for too long). Last night I ran a 12 gauge extension cord to the GE refrigerator to get 6 hours of data on the power needed (it took 0.460 kwh to recharge the battery this morning. So, 0.460kwh / 6 hours = 0.0766 KWH per hour). It's smaller than my old 2000w inverter. The build quality is excellent. The No-Load idle power use is low. Measured (*clamp-on amp-meter) with the charger in Float mode, at 50 volts x 0.09 to 0.15amps= 4.5 to 7.5 watts used (without any AC load). The inverter performed flawlessly. (*The inverter idle consumption loss is so low, it displays as 0.0A on the Android app for Eco-Worthy server rack 100ah battery).

I needed a power inverter to run power tools off site, using my truck battery. I tried a different brand that did not provide sine wave current and found them not performing well. I used this inverter to run a demolition hammer, rated at 900W and it performed flawlessly. The cooling fans didn't kick while I was using it so I can't rate it for noise level. Overall, I'm happy with it so far and hope it would last for a while.

Update: have has the chance to use my 2500 watt version with 48vdx input and a 3000 watt version with 12/24 vdv inputs. Both work fantastic and provide more than enough power to start small AC units, refrigerators and power tools. I am very impressed overall with the build quality the 3000 watt unit was being used in an extremely hot indoor metal building setting with temps well over 110F with no fan kicking on at all. The manual says when temp reaches 45C they will turn on. Have to say they're correct. The 2500 watt version is part of my home backup solution and is indoors. I have put up to 2000 ways of load for 20 minutes and no fans and handled it with zero problems. Using custom made cables (2 Gauge) on the 3kw unit and stock cables on the 2.5kw unit since it has less amperage draw on the Batts. Would reccomend and a very good value overall. Haven't used it yet! My bad! The unit is well built and has a good instruction manual. Comes with a plug in remote and heavy Gauge wires for the battery connection. I'll update once I'm using it.

UPDATE 2 - April 21, 2024: All good now. My self installed inline 60amp circuit breaker on 4/0 cable feeding DC to inverter was interfering with the inverter's logic causing it to shut down after brief 1500watt microwave oven load. Breaker removed, new wire installed, microwave runs fine & long enough to cook. Battery to inverter 4/0 cable gets hot so I'm upgrading that to 1/0. Very impressed with customer service & technical support. They responded in less than 12 hours over several rounds of email with intelligent advice & guidance. Full understanding of the situation. Also very impressed with the 3000 watt inverter. I took the cover off and noted excellent build quality, four sets of two 40 amp fuses, solid component sets, assembly well done & secure. AC outlets where most of the wear/tear would occur are solidly glued in place rather than cheap tabs I've seen on other inverter units. UPDATE Apr 14, 2024: upgrading the review 2 stars as Oleantp responded with a potential solution within 12 hrs of my post. Kudos for excellent customer service. Will update further after I implement their guidance. ORIGINAL REVIEW; Oleantp, need technical support please. I recently bought & installed 3000w 2024 inverter. Connected to two new 300ah lithium ion in parallel 12v batteries. 60amp inline breaker to protect wiring etc. Batteries at 99%. Low draw led lighting etc work fine. Heavier loads like 110v microwave plugged directly into the inverter start up & begin to load the inverter. After 5 seconds the inverter shuts down. The inverter resets & comes back on as evidenced by 110v led light also directly plugged in. The microwave clock comes back on. Restart the microwave to heat & cycle repeats. I’ve tried this independently with 1100 watt, 900 watt micro wave & very small toaster oven. The inline breakers do not trip. The operating watts are well under the 3000watt rating & dramatically under the 6000watt surge rating. What’s going on here? I’d like a replacement inverter please.

We own two OLTEAMP inverters. The second had a damaged remote control when we received it. The inverter itself worked fine otherwise (the remote isn't needed to operate the inverter but is very convenient) -- we contacted the manufacturer by email and received a replacement control in less than a week. Very impressive.

Hooked to furnace, works great.
