It DOES do what its rated for. However, a compressor runs with a motor that has a 2 step system. First step uses a capacitor on the side for the initial spin up. That capacitor is what's causing the overload. The inverter isn't designed to allow over current for short bursts. The overload protect will catch before it powers up.
With a single 100A rate discharge, you only can get 1200W -1380W output or throughput. If the load is more than that it will simply not be sustainable. And as a person mentioned, your charger might have been just feeding back on itself.
I am about to add a 2000w pure sine wave inverter / charger to my RV with 4 AGM 100ah batteries, I have a 2200w Modified Sine Wave inverter but figured it would not be suitable, Modified sine wave is hard on sensitive electronics and motors, compressors etc. Plus it takes more power as you found so thanks for confirming that... Will be selling Cheap! Modified Sine Waves are good for running lights, an electric heater or anything that is not sensitive to dirty power. I look forward to part two using a good pure sine wave inverter...
Hi I have the same inverter in my camper. It works pretty good. I have two 110 amp batteries connnected to solar The problem is the batteries draw down very fast During the day with 4 100 watt panels and moot controller I can run it about 1 hr before batteries draw down. With just the batteries I get about 15-2o minutes my ac is a window style 8000 btu
If your RV AC unit doesn't already have it , install the soft start capacitor kit on your AC unit like you mentioned. As a rule , you need one deep cell battery per 1000 watts of inverter you are using. Try using 3 deep cell batteries in parallel. The other thing to look at is these inverters are only 85% efficient. The battery power cables need to be 1/0 gauge TIMES TWO for positive AND negative.
I thought a battery of at least 2400 wh is needed to juice up the 2000W Inverter FULLY. As you suspected, another battery in parallel with a Pure Since 2000W continuous supply will run your AC.
Did you connect the grounds? You also may have a strange loop going on. When the plug to shore power is plugged in it also charges the same battery you are using.
Yup. The converter in that unit is probably charging that battery while the inverter is running, I’m not sure but I’ve been told you can fry your wiring quick running an inverter and converter at the same time like this
being plugged into the shore power cord is whats doing it. try it on a window AC. the start up onthat roof AC is a big pull and all that line loss is just a wee bit much....once running like you can see its pulling 1500w but start up is hitting over 2k.
I think I have something hooked up wrong in mind I have the same one you do except mines at 4000 W inverter I hook up a grinder and it kicks it out right away because I don’t have a grounded properly
Inductive loads don’t like modified sine wave and will have a hard time starting the load. Use a clamp meter to measure the inrush current of the air conditioner attached to mains and get a pure sine wave inverter that is rated for the inrush watts as the continuous rating.
As I'm sure you know by now, but just stay away from Modified Sine Wave inverters. They run inefficiently, and you can never run laptops or desktops, and they make everything buzz. I know the pure sine costs twice as much, but I would never buy a Modified. Also, you need at least two batteries, and four is better, to expect much use out of an inverter. As you saw with the AC test, the inverter finally delivered the power, but the batteries got drawn down in a matter of minutes. And finally, stuck with the good brands of inverters. I'm sure some of the Chinese inverters work OK, but I've had two of them, and one worked but didn't provide anywhere near the stated wattage, and the other one was worthless. I returned both of them. Magnum and Xantrex and Samlex are the best, you can't go wrong with them. I've had success with Aims and Giandel. They're less expensive, and do just fine. I have two Aims 1500w, one 24v and one 48v, and they still work fine. My 3000w Giandel is in use as we speak. And my Xantrex 1800 Prosine that I bought used and beat up, is still is use, and has been running for years. They're not on all the time, but there has been periods where both were running refrigerators and TVs, lights, computers and water pumps, for months at a time, always on. Inverters are by far the most fragile part of a battery/inverter setup. I've blow up a few, and had many others just quit after a time. Always buy higher than your needs. For your 9000, or 13500 AC, you should start with 2500w, and 3000 is better. Inverters don't like to run at full capacity for any length of time. And you can damage your AC by running with "just" enough power that it has to struggle all the time. Anyway, have fun, and stay away from those EVIL modified sine inverters.
I have no problem running a window unit A/C with my 2000 watts Aims inverter charger. It is 24 volts, I have 20 AutoZone marine batteries hooked to it.
I think these cheaper inverters are 2000w TOTAL. Each of those outlets probably maxes out at ~650w or something. The more expensive ones have a hard line output on them to get the full wattage output.
I have this exact inverter. I have it tied to 100 amp hour deep cycle battery which is also parallel to something like a 50 amp hour crank starter battery like a regular car battery is not deep cycle. It'll start my 5,000 BTU Frigidaire air conditioner which does have a soft start capacitor in it. It'll run that and it'll run a microwave that's about 800 w at the same time as well as some fans and some lights. I did not notice any buzzing or anything but I have heard long-term that these partial sign wave inverters can damage motors and things so I'm a little worried about that. But my inverter will run stuff. When I first tested it I just tested it using regular car battery jump start cables in one cable would not turn on. It gave me the overload signal and shut down and then I hooked two jump start cables to the inverter and the battery and found that it would work. With that knowledge I went ahead and opened the package for the $37 number two gauge 6 ft cables and bolted those into the 100 amp hour battery and to the back of the inverter and like I said it just didn't have any problem at all starting everything I had and running it.
2k,4kp will do it if it is a low frequency type with a big transformer inside. A low frequency pure sine wave inverter costs around $600 on the low end. Good demonstration of the limits of that jupiter though.
Did you connect them in series or parallel? If you have a 12 volt inverter and are using (2) 6 volt batteries you need to have them wired in a series to make 12 volts to the inverter. Just something to check.
There are multiple issues with your set up as noted in other comments. 1) A single battery will not give you the amps you need. Multiple batteries tied to a common bus will. 2) Obviously a soft start kit for the AC would cut your max start up draw and allow it to run. 3) The inverter is rated for total load (at all the outlets). Doesn't mean you can't get that load from a single outlet. 4) In any case, you would need 100s of amp hours of storage to run the AC for any reasonable time off of batteries, so this is not an appropriate use for this. High amp draw devices don't make a lot of sense to run from batteries for any length of time unless you have a relatively high amp continuous input source to the system. The inverter is functioning as designed, your system overall is not designed correctly.
Again. You missed the whole point. It's about false advertising on the side of the box. It's connected to the vehicle per the included instructions using the required cable kit. I understand how and why it doesn't work, it's about what the misleading box tells customers they can run.
And your last video a person informed you that you needed to install it easy start or otherwise known as a soft start on the air conditioner. Using a cheap inverter to power and air conditioning unit is not wise in the first place. But a 2000 W inverter even the top end Will not run even a 5000 BTU AC unit period. When the compressor kicks on an air conditioner the current demand can be five times that of what the fan is. You would need at minimum is 7000 white power inverter to run an AC unit without a soft start. And even with that it will destroy your batteries overtime even if you are using one of the best batteries there is. Install a soft start on your air conditioner or I can promise you we will have nothing but problems. And by at least a mid grade true sine wave inverter. Your electrical system and a mobile application is the absolute last thing you want to skimp on. Also generators are a completely different animal compared to power inverters they are very very different.
Use 00 cables and shorten lenght of cable. And honestly 2nd battery wouldnt be out of question either. Inverters require lot of power if you going to run high watt appliances. And 2nd figure out all your going to on inverter. In total watts. Then buy a inverter double the wattage you would use. And especially when trying to start up appliances like a/c air compressors that require lot of watts on start up. But then level out when running. Your inverter will work like it was ment to.
I try to covert someone to solar and they went and brought without asking me. Now they swear the will never use solar. Harbor freight is going to loose to Chinese companies in the end. At least they try to satisfy their customers, Harborfreight don't care.
I've done the math and my tv and ps3 draw a combined wattage of 1560. So, can anyone give me any advice? I'm trying to run The ps3 and tv. And on other days, i want to power some synthesizers. 2 and a powered speaker. I won't be using all that at once, though. Somedays i wanna make music, some days i wanna play mortal kombat with random people at the beach! If anyone has any advice, do let me know
You say you learned a lot, but obviously not quite enough. You need a pure sine wave inverter to run devices with motors. Like air conditioners. A simple Google search will tell you that. Slamming a product in not one but two videos is unfair, when your lack of knowledge is the reason it "failed" your test.
@@JackofAllMasterofNone regardless of whatever misguided info was included with the inverter, the facts remain. modified sine wave inverters are not designed to run AC electric motors. Wrong tool for the job. Again.
Trust me. I completely understand how electricity works. You completely missed the point. This is a review of a product and if it can perform as advertised by the company selling it. There is a long list of things that it can power on the side of the box. One of them being a window air conditioner. We both know it can't start that but they say it can. That is THE POINT
It DOES do what its rated for. However, a compressor runs with a motor that has a 2 step system. First step uses a capacitor on the side for the initial spin up. That capacitor is what's causing the overload. The inverter isn't designed to allow over current for short bursts. The overload protect will catch before it powers up.
Wonder if a pure sine wave would do you better. The in-rush for a compressor is probably quite a bit, plus MSW makes it run less efficient.
With a single 100A rate discharge, you only can get 1200W -1380W output or throughput. If the load is more than that it will simply not be sustainable.

Watching a lot of videos on these different inverters, went with a 3,000 watt puresine with two batteries too cover the extra juice needed.

How come did your air conditioner worked? the wave is modified sine wave? not so? Would it damage or short your ac life sooner?
Most of the problems with inverters is the input source and wires are undersized. May need bigger batteries and cables.
If your RV AC unit doesn't already have it , install the soft start capacitor kit on your AC unit like you mentioned.
As a rule , you need one deep cell battery per 1000 watts of inverter you are using.

Thanks. Was thinking of using this for a solar battery/ inverter but will now use something more proven.
Its plenty "proven". Ypure just trying to use it for the wrong job

A lot of ppl don't realize that to hit peak you have to turn it on at the switch. It peaks when you switch on the inverter
being plugged into the shore power cord is whats doing it. try it on a window AC. the start up onthat roof AC is a big pull and all that line loss is just a wee bit much....once running like you can see its pulling 1500w but start up is hitting over 2k.
I believe that inverter has a 4000 watt peak.
Will it power a small freezer?
I think I have something hooked up wrong in mind I have the same one you do except mines at 4000 W inverter I hook up a grinder and it kicks it out right away because I don’t have a grounded properly
Inductive loads don’t like modified sine wave and will have a hard time starting the load. Use a clamp meter to measure the inrush current of the air conditioner attached to mains and get a pure sine wave inverter that is rated for the inrush watts as the continuous rating.
Or a soft start relay and skip that stupid shit
If test with outlet test adapter the result was open ground. Equipment that uses 3 prong connector may need a way to provide proper grounding.
Inductive loads like motors are different than resistive loads... it probably can put out 2000W on a resistive load.

Did you try a soft start device for your AC. It works that way. And its better for your inverter too.
100A x 12v is only 1200W... Peak of 2400W for the 30sec time. To properly run an inverter you want at least double the running amperage cability.
2k,4kp will do it if it is a low frequency type with a big transformer inside. A low frequency pure sine wave inverter costs around $600 on the low end. Good demonstration of the limits of that jupiter though.
