Connecting the AC Wiring to the AIMS 10kW Split-Phase Inverter

[@Wijnamar]

Love these videos. The only thing I'm not comfortable with is that (not you as a person) you're using metal casings and conduits over there . Here in Europe (the Netherlands in particular) it's all PVC or ABS. I think its much safer

[@villiersman951]

yeh same here in Australia

[@LithiumSolar]

We do have PVC here, and it's a lot cheaper, but I strongly prefer EMT. PVC sags with time, requires more supports, and just looks like crap in general. EMT is much more solid, less prone to damage, can be used for grounding, doesn't burn if a fire starts, etc. EMT is the professional option, PVC tends to be the DIYer route unless you're running underground. We do not have plastic breaker boxes though, only metal, which makes sense. I would never want to use a plastic breaker box...

[@killuazoldyck1352]

Metal is fine for commercial or industrial, but for residential where aesthetics are an important factor, plastic offers far better choices for customers in terms of design and flexibility, if it as you say, 'melts, it burns, it catches fire, it sags' then it was installed wrong. it seems that you enjoy the industrial aesthetic, which is fine, but most people wouldn't want a shipping container in their garden or galvanised metal conduit all over their house. also in regards your last point, metal has it's own problems, as other commentators have pointed out with your mistake regarding induction!!

[@Wijnamar]

Here in the Netherlands, we don't use bus bars as you do in the USA each breaker is wired separately from the leakdetector ( I don't know what they are called but I think you know what I mean)

i get your consern but i perfer metal casing beacuse its harder for animals a such or small cruios children to get in. (you can use a lighter to get into pvc/abs fast)

RULE#1 (for the budding electrician) ~ Always cut your wire too long. Because if you don't it WILL be too short. Ask me how I know. ;)

[@LithiumSolar]

Yes! Once it's cut, you can't uncut and good wire isn't cheap! I figured people were going to complain that I left some slack, but glad to here that's not the case :)

@@LithiumSolar When I first became a journeyman electrician - being responsible for the entire job , I once measured a run through conduit with multiple 90's. It was over 150 feet of (3) 2/0 conductors. I pulled the very difficult run all the way to the breaker panel - when I got there I was about a foot short. Very sick feeling unsued. --> I had to buy all new wire. I measured very thoroughly, but not thoroughly enough. 😀

[@steverosenbaum2469]

You created an inductive heater from your j-box to the inverter and fire hazard. You need upsize your conduit so there are no hot legs without a neutral running in the same conduit. Also the wire size is too small to parallel per code. Not intended as a knock. I appreciate your attention to safety and detail.

[@LithiumSolar]

I'd like to learn more on this. The conductor only goes up to the meter for the reading, then comes back down the same conduit. It's not technically parallel conductors and the current would be flowing in opposite directions, so there should be no inductance? I don't understand how this would be different from connecting a 240 appliance, such as an air conditioner, where you do not run a neutral at all, only L1+L2 in the conduit. Do you have code numbers by a chance that I can research further?

[@gottfriedschuss5999]

Hi LithiumSolar, Sorry for the length of this response, but there is a lot here and it needs to have precision. Steve Rosenbaum is mostly correct. It is an absolute code violation to run only a hot leg in a metal conduit or through a metal box such as a panel board. NEC 300.3(B) To be code correct, for the reasons Steve sited, one must run all conductors of a circuit in the same conduit. If, in the USA, one has a 120 volt circuit, the hot and neutral (grounded conductor) must both be in the same conduit (cord, raceway, cable tray, etc.) For a 240 volt circuit, both hot legs, and if present the neutral, must all be in the same conduit. Finally, for 3-phase, the phase conductors, r, s, & t and if present, the neutral, must all be in one conduit. If one is running parallel conductors, all elements of the circuit must be present in each parallel conduit. NEC 366.20. For example, r1, s1, t1, & n1 must all be in conduit 1 and r2, s2, t2, & n2 must all be present in conduit 2. Assuming, of course the circuit uses a neutral. If grounding conductors (green or green with yellow stripe or bare conductor) are present, they must also be grouped with their fellow circuit components. Be well & Best regards, Gottfried

[@peterg.8245]

The laws of magnetics are a real PITA and I’m not talking about the bread. You have a neutral with twice the current path as one of your hots so theoretically you’re inducing a magnetic field.

[@steverosenbaum2469]

NEC Article 300.20 specifically refers to ferrous induction and NEC Article 310.10h refers to paralling conductors. Thanks Mr. Shuss for a concise explanation.

Thanks for making this video. It's nice to see someone explaining this unit I've had a hard time finding any info about it. I have one of these also, I still can't understand if I have to separate the neutral from the inside ground, (I have the outside ground directly to ground) if I'm connecting directly to my main panel that has both a ground and neutral connected together. We use the same electric system here as the US, two 110 legs, a neutral and a ground, but no 110 just 220, I'm planning on both 110 and 220. Also I'm planning on adding LiFePo4 batteries as well as keeping it hooked to the utility. It works fine with the AGM batteries we have now but I want to upgrade. Does anyone know if there's a way to disable the built in utility charger so only the solar will do the charging and is there a way to close the difference between the switch points from utility to battery and battery to utility. The settings all are either too low switching to utility or too high switching back to solar, I want it to run on solar as much as possible it seems to stay on utility way past the point where the solar provides more than enough power to run everything as well as charge the batteries.

[@SuperVstech]

And when using metal boxes and metal conduit, you are supposed to ground the boxes, and each conduit connector with bronze abrasion protectors, with ground bonding connections.

[@LithiumSolar]

All of the metal boxes are grounded. The EMT conduit does not require grounding. I used the proper threaded connections, which bite in to the metal box, thus grounding the conduit.

[@SuperVstech]

LithiumSolar By Michael Johnston Published In February 2013 Grounding electrode conductors are essential in the grounding and bonding scheme for services and separately derived systems. They generally must be sized according to Table 250.66 of the National Electrical Code (NEC) and are required to be installed in a continuous length or otherwise spliced in accordance with any alternative in 250.64(C). They must also be protected in accordance with 250.64(B) where subject to physical damage.
 In addition to concerns about physical damage, magnetic fields can affect grounding electrode conductors. Section 250.64(E) includes requirements to address such protection. If a grounding electrode conductor is installed in a ferrous metal raceway, the raceway must be electrically continuous from the point of attachment to the cabinet or equipment to the grounding electrode and must be securely fastened to the ground clamp or fitting. Ferrous metal raceways contain iron or steel content, and examples include rigid metal conduit (RMC), intermediate metal conduit (IMC) and electrical metallic tubing (EMT). These conduits and tubing have a magnetic property that reacts to rising and falling magnetic fields present in alternating current (AC) systems.
 Varying amounts of current can be present in a grounding electrode conductor during normal operation. During a ground-fault event, the current in a grounding electrode conductor can fluctuate and even be relatively high for the duration of the event.
 Ferrous metal raceways must be bonded to the contained grounding electrode conductor to reduce the effects of magnetic fields that are present while the system is energized and in use. The grounding electrode conductor for an AC system or service is an AC-carrying conductor with the current flowing in one direction. This current can rise and fall significantly depending on events such as ground faults, short circuits or line surges. As the current rises and falls, the magnetic field of the contained conductor typically gets larger and smaller accordingly. This means the stresses on the contained grounding electrode conductor increase and decrease as the current goes up or down.
 Because the ferrous metal raceway is enclosing this single conductor, there is an inductive reactance between the ferrous metal raceway and the contained grounding electrode conductor. This inductive reactance is one component of impedance and actually impedes current in the contained grounding electrode conductor. The magnetic field and the capacitance results in a coupling effect between the current in the conductor and the surrounding ferrous metal raceway. In actuality, the majority of the current would be present in the ferrous metal raceway rather than the contained grounding electrode conductor.
 The magnetic field’s strength increases in proportion to the amount of current in the conductor. In many cases, the magnetic lines of force in the conductor are induced into the conduit enclosing the grounding electrode conductor; they can even surpass the saturation point of the steel raceway. At the point where the grounding electrode conductor exits the conduit, the magnetic lines of force generated by the fault current in the conductor will try to be induced on the end of the conduit, creating a saturation point that exceeds the conduit’s capacity. The steel conduit, in this instance, acts like a steel core of a coil to concentrate the magnetic lines of force. This condition is often referred to as the “choke effect” because it is actually the restriction of a grounding electrode conductor from performing its function. Because of this, specific bonding requirements are necessary for ferrous metal raceways that contain grounding electrode conductors. This is not a concern for grounding electrode conductors that are installed in PVC conduit or other nonferrous metal raceways such as aluminum or brass conduit. Sometimes the type of construction will not permit PVC conduit.
 Section 250.64(E) requires ferrous metal enclosures for grounding electrode conductors that are not physically continuous from cabinets or equipment to the grounding electrode, such as sleeves or short lengths of conduit used for physical protection, to be made electrically continuous by bonding each end of the raceway to the contained grounding electrode conductor. This action puts the contained grounding electrode conductor in parallel with the enclosing ferrous metal raceway so the two work together when the current in grounding electrode conductors rises and falls in response to various events occurring on the system. The current will actually divide over both paths, but due to the skin effect, the majority will be present in the surrounding ferrous metal raceway.
 The methods required for bonding each end of the raceway are provided in 250.92(B)(2) through (B)(4). These methods apply to all intervening ferrous raceways, boxes and enclosures containing the grounding electrode conductor. If a bonding jumper is used to accomplish this bonding to intervening metal raceways and enclosures, the size of the bonding jumper must not be smaller than the required contained grounding electrode conductor as provided in 250.64(E). Several manufacturers produce grounding and bonding fittings that are specifically designed and listed for this purpose.
