Great job testing the inverter! Decent price for what you get too!

Those specific people with specific circumstances are more specific than some people might think. Most of the people that *think* they have such a special case can better solve their problem using a generator transfer switch and a regular cable. That, or hardwire your temporary solution without using plugs. Long story short: If you have a generator, install a transfer switch instead of creating a suicide cable. And should I ever find myself in need of one, I'm sure to disassemble it as soon as I'm done using it.

Yes. As I watched. I was thinking where's the heatshrink.

Same

I would put some of those PG strain reliefs there so the wire is supported by the housing, not the circuit board. The ones that screw into the enclosure with standard electrical lock nuts, and have the rubber gland that clamps down on the cable.

You are correct. It would have been safer to do connect them in the opposite order. I often work with live wires and breakers, so I'm fairly comfortable with it. Maybe too comfortable? ;-) Honestly, I wish I had done it the other way for the video. I was already doing something sketchy, at least I could have done it in the least sketchy way possible!

in my limited experience, sample review pieces always have top notch quality. its retail sale pieces where corner cutting takes place especially for Chinese manufacturers

@@lordjaashin I could see that. Question is if they expect you to open something like this

For anyone looking to add/improve waterproofing on circuit boards for devices that are outside often, CorrosionX and especially CorrosionX HD work really well for preventing water damage to electronics

"The farther apart the conductors, the higher the resistance." -- Don't you mean impedance? I assume the problem is the magnetics from a large loop of cabling, or am I misunderstanding?

​@@chuuni6924 Depending on how the conductors are laid out, you'd have to be concerned with both reactance and resistance....... so, yeah. I guess impedance would be a better "blanket" term for the issues.

That said, I'd just run 2 welding cables (#4 cable, like GoCoyote said - they aught to be fine). Stick them in a wire loom or maybe a long piece of heat shrink and call it good. Edit: I would NOT however use jumper cables. A lot of them, even the big, high amp ones are copper plated aluminum conductors.

@@chuuni6924 In DC circuits, it will actually be self inductance that causes the resistance. Here is a fairly cogent explanation from an old Trace engineering manual. When current passes through a conductor a magnetic field is set up around the conductor. As this magnetic field builds, it induces voltage in any conductor that is close by, and it induces a voltage in the original conductor. The voltage induced into the original conductor is called self-inductance, and tends to oppose the current that produced it. The magnitude of the self-induced voltage is proportional to the size of the loop formed by a wire. The larger the loop, the larger the self-induced voltage. The positive and negative battery cables in a system are in reality only a single circuit (wire), and so the inductance of the battery circuit depends on how the cables are physically positioned or arranged with respect to one another. If battery cables are separated by a distance, they have much more inductance than if they are close together. If the two battery cables were coaxial there would be virtually no induced current flow since the magnetic fields would cancel one another. However, we don’t have coaxial battery cables, but we can approximate them by taping the cables together every four to six inches. When the cables are taped together, the magnetic fields around each battery cable tend to cancel each other. When cables are separated the magnetic fields add together and increase the inductance of the battery cables. If you aren’t convinced that taping battery cables together helps reduce inductance, consider the following table of information collected by Trace Engineering. We tested two sixteen foot long #4/0 AWG battery cables connected together at one end and parallel to one another. Table 8, Battery Cable Inductance Distance Between Battery Cables Inductance in micro-Henries Taped Together 3.3 12” Separation 6.0 48”+ Separation 8-9 The above table shows that with only a foot of distance between the battery cables the inductance almost doubles, and at four feet between cables the inductance is almost three times the inductance of cables taped together. Since the induced voltage in a conductor varies as the inductance times the rate of change of current in the inductor, the induced voltage may be three times greater than it would be if cables were not taped together. For more advanced readers, consider flyback effects and the induced voltage spikes can get into the thousands of volts range if the battery were suddenly removed from the circuit (worst case). These induced voltage changes cause ripple in the battery cables and must be absorbed or filtered by the filter capacitors in the inverter. This ripple will lead to eventual premature breakdown of the filter capacitors and performance loss in the inverter. In addition to the problems mentioned, the induced current opposes the applied current (battery current) which directly causes a loss of inverter performance as greatly reduced efficiency. To avoid this problem, route your positive and negative DC cables in parallel, as close together as possible. Secure the cables against movement with clamps or straps every 18 inches. Avoid routing conductors near heat sources such as dry exhaust or furnace piping. Avoid chafing sources such as steering cables, engine shafts, and throttle connections. Hopefully this information gives a much more realistic and clear idea of why battery cables should be kept short and close together. Maximum performance is the goal of any well designed power system and the details such as this will help achieve the goal.

@@GoCoyote A Flyback Diode could be used in case of battery removal.

Agree100% I thought my shop was bad-ass his put's mine to shame!!

That can be mitigated with some worn out scotch brite pads and some double sided tape though.

Not if the fans blow out and or you filter the air intakes.

Thanks for reading my mind.

@@johnhamilton9229 lol

Would need to heatshrink those things. That stuff is a "grease", right? If it is that stuff can be messy.

The suicide cord is the least of his problems ! The inverter is for indoor use only and wont last long at all ! what a shame.

Remember he got it for free, we have to pay for it if we want it, changes everything

I have know idea why it connected me to one of my sons online game names. My name is Kevin Clewis. Didn't what any misleading information.

I suspect it would make very little impact in reality. It looks and sounds like a great idea but once you do the math on what solar could potentially offer (even best base) vs charge time, it's almost pointless.

@@nfavor how often does he use it? in the meantime, it can charge from the solar panel.

You are correct! I now know from experience as well!

Actually I really don't plan to run the shop in that manner. I should have been more clear about that. The main reason I did that was to be able to test the inverter against my big shop tools. It is nice to have as an option in a pinch, but really, if the power is out, I don't think I'm going to be woodworking with my golf cart batteries!

Agreed on the capacitor, I noticed I was hoping he did a double take after already safely uncharging it because I felt stressed

thought the same. I really dont like exposed wire and you can touch the high voltage from outside the case. That should really not the.

Agreed. I think, he just slapped it together for the video. He's a smart guy and am sure would normally do it.

@aullik You cannot touch the high voltage from outside the case. Not sure what you mean. The battery voltage is 48V and it will not shock you. Even so, I did tape those ends and they also can't be touched from outside.

More for a corrosion stand point on big cables,it starts there and spreads up the wire.I assemble with silicone electrical paste too.Awsome video's, thanks for showing us your beautiful farm.
