novopal1000 Watt Pure Sine Wave Inverter DC 12V to 110V 120V AC for Home, RV, Truck, Off-Grid Power Inverters with Built-in USB/Type-C,4 AC Outlets,Remote Control and Dual LCD Display (Upgrade)

My husband purchased one of these this summer for our round trip drive to the lower 48 and back. We wired it up to our RV to maintain his oxygen machines while moving and it worked beautifully!! Well worth the price and security in knowing he would have oxygen!

Muy buen inversor, con materiales de muy buena calidad, por el momento está funcionando muy bien y eficiente.

Bought this is December of 2023. Used it for 10 months now. No difference in everyday appliances. Worked great and was very pleased. 1 day I turned it on heard a loud pop and smelled burning plastic. Killed my whole system and tried each thing individually. Turns out something in the inverter blew. Not the fuses I checked those they were all fine. My inline t fuse was fine. Inverter just took a dump. Good thing I was home and caught it. Couldn't imagine getting home and finding everything burned down with my dogs or family inside

Working good so far

PREFACE: I come from many years of 12v background doing car audio and automotive electric so i have in depth knowledge on how to setup and run things properly.I got this to run my TV in my trailer (110 watts), yes it's WAY overkill but i want to have the ability to expand on it and have more inverter outlets for things like coffee grinder etc so i can keep the generator off as much as possible. I made (2) outlet drops using 12/3 all length's are less than 15'. I have 300 watts of solar on a MPPT controller in the RV as well, sure it's not a lot but it's plenty to recharge the battery's through the day, but i will be adding 300 more watts even though it's not needed for full sun applications.At first I was frustrated because it seemed to drain the new battery bank in minutes, but i had suspected i had bad batteries that I had just got. it was confirmed with a float test and battery's replaced then fully and properly charged to 100% then floated for 12 hours. After that I put on a load and dropped to around 60% or so allowing them to charge fully using higher amps which pushes any electrolyte off the plates for maximum performance from batteries, I did this a total of 5 times... so they were properly charged. This is wired with DUAL 4 gauge power and ground (overkill), each of the grounds goes to the same ground point on the chassis as the battery which is on each side of the trailer to insure perfect ground. Battery's are DUAL 6v batteries with 240ah each so there's plenty of HP there. Battery bank also is augmented with dual 3 farad capacitor's to provide surge power (likely half that per capacitor, but way overkill for small power needs during surge),Upon turning on the power to the unit the battery would immediately drop from 100% charge to 91% given the AH capacity of the batteries... ok so sure there's a bit of a load there but 9% when absolutely nothing is running is suspicious. I let it slide and went to do my test on the unit running only off the battery and not any "shore power" or "solar" as it would be during the evening when no sun was present. I ran the test for a total of 3 hours as follows0 hourturn on inverterturn on all LED lights in trailerturn on water pump (always caused a surge and less than 1 second light dim prior to capacitor, no more with capacitator) Ran for about 90 secondsturn on 55" LCD TV (110 watts)** battery went from 100% to 91% after only turning on inverter** battery went from 100% to 89% after above** Turn off LCD & Inverter, battery went up to 97%1 hourinverter has been running fineled lights are on, no issueswater pump is off55" LCD is running, no issues** Battery was showing 71%** turning off inverter briefly battery went to 82%** turning off LED As well battery maintained at 82%2 hoursinverter has been running fineled lights are on, no issueswater pump is off55" LCD is running, no issues** Battery was showing 58%** turning off briefly battery went to 70%** turning off LED As well battery maintained at 70%3 hourinverter has been running fineled lights are on, no issueswater pump is off55" LCD is running, no issues** Battery was showing 42%** turning off briefly battery went to 63%** turning off LED As well battery maintained at 63%****** Stopped test at 3 hours as you don't want lead acid battery's to go below 50%, knowing there was average of 11% loss with the unit I stopped here as it was above 50% without load, once the battery was lower it showed around 19% less battery when running.given the extremely low wattage use on the inverter the one i got is suspect as it seems to be using a lot more power than it should being 1amp at idle, i'd assume 3amp or so running but could be 4amp at most. As the inverter being powered on averaged a loss of battery power of 11% with a decent size battery bank this unit seemed to be using more power than it possibly should be thus causing a much shorter battery life.A close friend of mine has a 4000 watt inverter by a company name starting with "Ren*****", his battery bank is 1/2 of mine in a similar setup. He was able to run his inverter the same weekend using his 60" LCD TV that is rated 130 watts for 5.5 hours on day 1, 4 hours on day 2. He has 400 watts of solar. Inverter was ran in a mix of daytime and evening so this would account to a degree for longer times, but not to this extent given 1/2 the AH of the bank.This wasn't a scientific test by any means but it was a test I would have run when I was doing 12v many years ago, this would give me an idea of the performance.I have requested Amazon send me a replacement unit as I now suspect the unit could be defective and or have some sort of battery leak causing the drain. I will have the new unit today and will install today and re run the test a few times to see how it runs. If the result is the same I will return the unit for a refund and go with a different brand.

I am writing a review because I see some bad reviews of people saying it would not power a 700w microwave. 1st off if you have a 700w pure sine it will power 700w however it will almost certainly trip the inverter alarm. First thing I did was upgrade the power and neg lines to 1/0 as the 8/0 cannot handle the load. Now running any high load device will drain the battery quickly. I ran lights, tv and coffee pot for 2 days on a single charge before having to recharge using the 1500w pure sine. I bought the pure sine because it can handle the heavier loads such as heating elements. I did accidentally burn out the fuses, easy to replace by removing the 8 screws. 4 on button side, 4 on fan side. The remote is just a inaccurate battery meter but allows you to house the inverter out of sight and turn it off and on. I unplug the remote when not in use as it does draw a minimum voltage when plugged in as the main unit has to be in the on position for the remote to work. Its the only con. Its a good buy so far after several months. Again I always upgrade the wires from the stock 8/0 to at least 2/0. The 8/0 just don't cut it. Adequate for running low wattage but something like a hot plate or small microwave, never.

I bought this in March 2021 along with many other pieces of equipment for my RV. I installed 2 Lynx LiFePO4 batteries (Excellent) 120 Ah's each, a solar controller, 2 solar panels, Victron smart shunt, and quality copper 2 AWG cables. I knew the included cables would never sustain the amperage required for 2000 watts. After my system was installed I did some testing and was disappointed that the inverter could only produce about 1300 watts before tripping. Discouraged I kept researching and found that just ordering precut cables with 3/8" lugs was the most likely culprit. I ordered some battery crimpers and numerous size lugs, I had numerous size requirements as the breakers come with 1/4" studs, my battery needed 5/16" and the shunt required 3/8" lugs. Once everything was cut to length and properly lugged, I retested and now it can hold over 2050 watts sustained without tripping. It can also can go to 2800 watts for a short duration without a trip. So to make a long story short, this thing works as advertised, however you need to use quality proper cables and lug sizes or your never going to get there. The only negative I have seen is this inverter only produces 110V at max with no load, at 1400 watts I was down to 105 VAC. At 2800 watts my voltage dropped to 101 VAC. Not Ideal but I doubt I will ever need that kind of power for any kind of duration.

I bought this product in June just now at the start of December hooked it up to my solar system and it turns on flashes a bunch of times and turns off. Does not work at all and Amazon will not warrantee it or return it. Should have better return policies on electronic items. The company is based out of China and no tech support or returns to them at this time so I am out $300 in an item that never worked.
