When RUclips channels review a product and recommend it, I generally take it with a grain of salt. You never know what "PERKS" the RUclipsr is getting. But when a RUclips channel does NOT recommend a product, that channel gains my trust. Thank you for (as I can tell) always giving honest reviews and recommendations.
You're welcome! I feel bad when a company puts the effort to contact me and send me a product just to find out it doesn't hold up to my standards. Thanks for the comment!
Either way the results may not be accurate. The reviewer has to know how to properly test things!. He neglected to check the battery voltage during the test. If it is low, the inverter will never put out its rated wattage. Another issue is the voltage drop of the input cables.
I'd monitor the input battery voltage at the inverter before kicking it to the curb. For some reason (cheap!) all the cheap inverters come with wimpy battery cables/terminals. You might be dropping a fair amount of your 13V when the inverter's trying to pull close to 200A at full load. That might be why it was beeping, not overload, but close to under voltage. I used dual 4ga cables on my 3000W unit, and as short as possible. and solid copper lugs, crimped and soldered. Never got warm, even when running 1.5HP well pump. I suspect that the unit just didn't have a stiff enough input to sustain it's output voltage. (Or it _is_ a piece of garbage anyway...:) Always interested in decent budget power stuff. Keep on with the videos! Stu
I know all the connections were tight and the cables were the ones that came with the unit. If they are sending me a unit with cables sooo crappy that it can't draw the voltage from the battery, then that just adds to my concerns. Thanks for the info and the comment!
That are Chinese Watts. When working with such powerful battery, you need always take the necessary precautions. For example, add a fuse in between because you can never know. At a short inside or outside (clamps), with 200 amps it can melt metals and weld it together easily. When that happen, you really need to run to the outside. Always use a fuse (in off state) and never connect it with live terminals. I have to mention this because I had an inverter with a loose/lousy wire terminal connection INSIDE the unit and it wasn't protected with heatshrink or a plastic. You have to be careful, even when it is brand new. Now the first thing I do is open it up to see if everything is fine and connected properly. Also check the quality of the wires and solder connections.
weird you have that amount of voltage drop, that's usually a battery issue, not the inverter. I wonder if the AC voltage really was 111-112 volts before the start?
The battery was more than able to pull the power needed. I believe the inverter is programmed to lower the AC voltage when it gets too high. It acted like the EB3A when you have it on power boost mode.
I agree with you. I just purchased a 3,000 watt and I am sending it back. It has a low whistle even when no load and powered with 400 amps of lithium and 2awg 2' cable still beeps intermittent intermittently. with a 1,000 watt microwave. Just not up to what it should be. Amazon choice made me think it was good.
I'm curious to know if it's those cables or not. The cables these inverter manufacturers provide are pure trash from every company, especially these ones where they are those split kind. I wouldn't doubt they really cheeped out and it's also CCA on top of being split small gauge wire, that's my experience with those kind. Soon as I see the split wire, I toss them straight in the trash. I honestly wish they would just not include cables at all rather than send these things out with something that's potentially very dangerous to use.
The cables held you back. It is unfortunate they included dual 8awg, that are soldered and then crimped (worst assembly possible). Basically, the inverter was starved of power. Do that test with quality cables and it easily surpasses its ratings. It would have been best if they just did not put those cables in the box and your review would have a very different outcome.

I understand the scepticism. The lifepo4 battery was over 80% capacity with a 200A BMS. I know voltage wasn't a problem, but you're right.. I should've put a volt meter on the battery during the demonstration. As for the wiring, I used the wiring supply with the inverter. I know it's not the best, but if topbull knew their cables couldn't handle the amp draw, then that is another issue in itself. Thanks for the comment.
@@OffGridBasement I would like to mention that a battery may not actually produce the current specified. To be really scientific, it's best to check it and the input voltage to the inverter to see if it's actually providing the current and voltage needed for the inverter to produce its rated output. A huge issue of course is that with a 10 fold voltage increase from the battery provided by the inverter, there is an approximately 10 fold current requirement to produce the voltage (an additional small amount of current is needed to compensate for conversion inefficiency). Concerning the rather small gauge cables supplied for the inverter issue, as you mentioned, I'm really surprised the manufacturer or seller provides four cables to prevent unnecessary voltage drop and wasted energy as heat. The manufacturer or seller really needs to address this issue. It's very nice that there are people that take the time to make videos to test devices so we can see how they perform to help with our purchase choices.

Good point. I bet thoes wires wer warm

That was a disappointing outcome. Thank you for the review!

Thank you for the great information. I'll set up a bit better on the next review.
Have u tested the harbor freight Jupiter 2000watt pure sine wave inverter? Can u do it?
I don't know anything about the jupiter inverter. I could try finding one to review. Thanks for the comment.
retest with larger cables, and then open it up
That seems to be the general idea. I'll give it a shot. Thanks!

@@OffGridBasement Brad Cagle just did a review on the same Inverter and the inverter didn't break down.

Thanks for sharing and for the comment.
Could you try PumpSpy 2000W inverter?
I'll look into it. Thanks for the comment.

I'll give it another try with proper wiring. That seems to be what everyone is thinking. Thanks for the comment.
My brother look if there is a pod can turn the voltage up to 120v AC.
I'll check it out. I've been meaning to dig into this inverter. Thanks for the comment.

I will do a second test on the inverter to further investigate. Thanks for the input and comment!
That battery of Yours, does'nt it only have a 100 amp BMS??? - if so, then the battery should cut off at around 1200 watt...
No. It's a 200ah Battery with a 200A BMS. It has plenty of power for a 2000w inverter. Thanks for the comment.

I'm not exactly sure how this pertains to this video.

You have done ✅ hob
Thanks for the comment.
I am subscribed, so if you do a follow up on this I will be watching. Thank you.
Will do! Thanks for the comment!
I bought one it quit working as soon as I bought
I've been suggested that the wires are too small, but I'm sure it's the inverter that's got the issue. Sorry for your trouble.
dam thanks for sharing
No problem 👍
