ok so this is 2 phase 110v inverter, seems they are calling it split phase but its actually 2 phase 110v with Neutral built in , i am assuming that you can have 2 fuse boxes then that runs of one L to each box? i am in UK so Neutral is Neutral return power comes from the one phase only witch is 240v live (no split phase same as most places that use 240v in the EU)
This is a single phase not 2 phase you need to learn about phase and what it means yes it has two 110 volt outputs but it's a single phase output @ 230 volts as well with 180 degrees with the polarity opposing each other sorry but UK don't have the technology in there power grid like the USA and you need to learn about phase power and the many phase power system we use here with split phase.
just throws me how split phase works, I should look it up a bit more from UK so 1 phase 240v and 3 phase 415v or each of the 3 phases can be used as 3 240v single phases, most domestic building in Uk only have 1phase but tends to be 80A 240v on avg (some have 100a and power pole fed power tends to be 60A) so can easy run a cooker and power shower same time no Issue (farms and industrial/ commercial places tend to be the only places that has 3 phases)
lee x three phase allows you to run Motors efficiently with three wires single phase allows you to run 110 volts on two different circuits with a neutral and also 240 volts between both circuits
This is split phase 220/240v. Yes, it makes the AC Appl's run efficiently as compare to single with only 2 wires (Hot and Neutral). Split phase makes your conductors (2 Hot and Neutral) live a bit longer. As it shares the voltage and current unlike in Single Phase hot wire solely bears all voltage and current as well.
I am so glad that you made that Video...you are a life saver...I almost burnt my house down...i could not figure where the 240v was coming from...my fridge lites in my garage were super bright...lol thanks a bunch..
Thanks for the clarification. I now get a better sense of what type of inverter you have through it's wiring diagram. I wasn't aware of the AIMS 240V line of inverters.
L stands for "line". This inverter electronically emulates a split phase system: a 240V coil that is tapped in the middle for the neutral, from which reference point one side is "arriving" while the other is "leaving", therefore 180 degrees apart. Each of the two lines carries half the capacity of the phase. In a separately derived system (transformers/Inverters), the neutral is bonded with the ground, this is why you cannot connect this neutral to any other system's neutral. You should use the ground on the left for both input and output circuits.
@Steve Bobo Steve You have G/L/N this means you have an inverter that is Ground/ 110v-120v hot Line/ and a Return neutral for ONLY 120v application. You cannot have 220/240v. You inverter is strictly a 110v-120v. If you tried to split the Hot line it will not be phase. Both Hots will not be out of phase and damage your Unit. Do NOT tap the L1 and try to do 240v This is DANGEROUS and will lead to system failure! The ONLY Inverter that can be used in 220v-240v is an Inverter designed with split phase that HAS (2) Hot legs built in it. L1 and L2
Hi. I have a question I'm hoping you can help with. I understand your video that you need a dedicated ground for the inverter. In main service panels in the US, the neutral and ground are bonded in the panel. So even if I have a dedicated grounding rod for the inverter, isn't there still going to be problems if I take the neutral from the inverter and connect it to the neutral/ground bonding bars in my service panel since, while the inverter is on it's own ground, the neutral in the service panel is also ground? Thanks.
Did you ever come up with a solution to this problem? I have the same (or similar) inverter and have found partial explanation of how to disable the "Automatic Ground-to-neutral" switch but I am still unsure how to safely connect my inverter to my panel. I do know that you cannot have two ground/neutral bonded connections between the inverter and main panel at once. Thank you!
Thanks for that it makes more sense now. L1 and L2 are 180 degrees out of phase with each other. do you have a link for purchase of that inverter? john
Ok so I know I'm gonna sound stupid probably but I'm used to wiring 120v/240v in a home or garage but not used to wiring with an inverter so here I go. As I see it, input is ground, hot from one leg and hot from the second leg off the main 120v panel. Going out, neutral and two hot feed the two legs on the subpanel and just need to be grounded well? Am I in the ballpark? LOL. I'm sure I understood correctly but I like having confirmation before I blow myself up lol
I would like to know what is the largest size wire that will fit into lugs on the aims?Also I take it you wire the sub panel on the solar side with a red to one leg and a black to other. Do you then hook the true neutral to neutral bar and drive a separate ground rod for the sub panel side. Thanks in advance.
subpanel needs a bond from main and inverter needs a ground rod copper or 2 rods test for resistance to ground and do not connect the neutral from the inverter to a ground from the main sub panel should not be bonded from the neutral bar to the panel itself
Because the neutral from the grid is connected to your main panel, that's why AIMS states you do not want to connect your inverter neutral to the panel neutral (grid).
Good video....!!! That manual is not good!!!!...I have a question.... for your subpanel...then you have to bring the neutral and the two hot lines from the inverter to the subpanel via a transfer switch...but ...what you do with the ground???.. are you using, the ground from the home or the new ground from the inverter ??? ..My best guess is to use the ground for the home breaker panel (it is already installed as part of the original circuit)...but this will work if the main breaker are off. It is complicated from the fact that you need to look for the circuit that you want to power (from the main panel)...but also for the line that return (neutral) to the breaker panel. Both lines need to be moved to the subpanel via the transfer switch...it will be a pain if you need to move also the ground!!!!
I have a new Sigineer 6kw split phase inverter (2021) and the wiring diagram is different. They now want ground and neutral plugged in on the AC output side, and just L1 L2 and ground for AC input. Wiring option 2.
Thank you so much sir, for informing us. You've a good heart. If most people wanted to help one another, would there be so much need to yearn for heaven?
what do you get for voltages on the input side when you measure L1 to ground rod and L2 to ground? this is like what the utility grid provides to ours houses, two hots and a ground. I wonder if most people that hook this inverter up to the grid input do it wrong.
+Rev John O'Toole how do you use a utility I use a ground rod and outside the backyard I drove it in the ground 10 feet deep so it'll never be the same as what you get because the ground is going to have resistance between the circuit
What is the ground on the other end (AC) for if ground is needed on the DC end? Do both ends need to be grounded? This says it is a charge controller. How are solar panels and batteries connected when there is only one spot for DC connections?
Now that was enlightening! I'm still researching as to who, other than Aim's, which is built by a parent company, makes 240V split phase inverters. I know these Chinese units pull all kinds of punches to keep the cost down. Like my Reliable 3500 watt 120V unit has a floating neutral. If I wired it into a service panel, even for just one phase of it, and tied the inverters case ground AND put the neutral to the bus bar....Blam! The smoke comes out! Most US panels tie the ground to the neutral (bonding) and go back to the utility power transformer AND to a ground rod outside the home. Now, with your Aim's unit there, isn't attaching the inverter's neutral to the panels neutral/ground bus, AND the other "ground" on the inverter to it's own ground rod still going to blow it up? Because if your panel has a bonded ground/neutral, it's the same as being grounded? Hmm.
Curt I had a brain cluster f*ck when it came to the how this is wired. My 6,000watt aims has two grounds. One on incoming power and below is a case ground.
I have my Aims 24 v 6000 watt split phase inverter output wired to one side of the transfer switch then wired to the main panel 100 amp entrance outside from the mid point of transfer switch to throuout the house . I have the deep mains that’s from the meter wired to the other side of the transfer switch .Both red and black hot wires of the mains and inverter goes to each breaker on both sides of the transfer switch while all the white neutral wires are hooked to a block connector of the transfer switch that’s isolated and should never be connected to ground or to the box .The inverter case, charge controller case, solar panels , wind turbine if you have one or any other that’s only associated to the inverter are souly should be grounded to a designated ground rod . The main entrance panel has its own ground from the box outside .Now both phases of the mains and the inverters neutrals should never be grounded at anyway to any main and or transfer switch box .Even though you don’t want current to go through , or to be connected to any or your mains or inverter hots if there’s a short , for example a hot wire that come loose and touches the grounded metal part like a drill case or light fixture . There’s no way the current from a light short on the inverter that can contact the mains hot wires if both mains and inverter phase neutrals are connected together isolated from ground .Im no electrician but that’s how my setup is wired up . I hope this helps . Watch my solar setup videos and leave a reasonable comment . Thank you , Shi shi ,Doh Je .Arigato gosaimasu ,gracias !
Pretty sure it says "NEVER" Connect and to the left it says, Hot, Hot, Ground> Maybe Ground, Hot, Hot would sound better, but its clear its not Neautral
Ground is the chassis of the inverter N is Neutral hot in is split phase power coming in and hot out is split phase power coming out I'm going to do a sine wave video demonstrating demonstrating this soon I hope you enjoy it
Hi, loved the video. I am about to design a solar system to power my entire home and I am looking to buy AIMS pure sine wave 8000, 10000 or 12000 watt inverter. I am installing enphase micro inverters under each of my panels (14 total) to draw AC power directly from my solar panels. Is it possible to run that AC feed into the AC input of the inverter? and have the output go to my main panel. I will connect a battery bank to the DC connection for the batteries to take over once the pannels loose sunlight. Will the AIMS inverter allow that?
+Kafui Andre Not aims, magnum can do this and it's really good at it and I would start at 48 volt and a 4400 watt magnum and you can stack like 8 of this type of inverters. Aims is really a bad choice
From listening to you explain the difference between Neutral and Ground on your House system I think you might be surprised to learn where your Neutral and Ground wires are attached in your breaker panels. I am assuming you are here in the US as I don't have a clue how wiring is done anywhere else.
+Rob NAustin yes we are on US. The only reason why I gave a detailed description on this wiring it's because the inverter manufacturer gave a poor job of describing how to wire up this type of inverter to a breaker panel attached to a grid.
I made this mistake and fried my inverter. Never connect the nuetral from main to the input of the inverter. It has to be a separate ground + 2 hot lines.
thanks - i have a single phase 5KVA pure sine wave 230v inverter , 230v Ac input & Out-put is single phase 230v , i want to wire that 230v & the inverter says its - Ground L N Ac INPUT 230VAC & Ground L N Ac OUTPUT 230VAC 5KVA 48v 93A PV+ PV- i want to wire it straight to breaker box on its own private 100 Amp Double pole breaker which is good for 600v and will split the 93 Amp & 230v an electricion said to fuse everything and tighten all tight and check the laws where you live about legalness make sure all you do is better than the code 12 gauge wire use 10 gauge
If you're going to use a 100-amp breaker you need to use a 100 amp wire cause a house fire it's not done correctly needs correct size wire for 100-amp breaker
Gee, thanks for explaining the manual to me... because I don't know how to read. Now I'm 8 minutes older (ok, 5 minutes; I didn't watch the whole thing) and still looking for a video of someone's whole installation.
Hey guy, with all do respect, please don't speak electrical or even advise anyone on electrical matters, sooner or later you or anyone who follows your advise is going to get hurt, you're. Right you are not an electrician as you rightly speak a few times, so why explain something you have no clue on
correct me if im wrong the whole power grid including the poles are grounded to the ground so your house panel is grounded as well , how does the inverter go to ground if it generates its power inside itself . power always wants to return to the path of least resistance which would be back to the case on the netural
ok so this is 2 phase 110v inverter, seems they are calling it split phase but its actually 2 phase 110v with Neutral built in , i am assuming that you can have 2 fuse boxes then that runs of one L to each box?

6:49 , I think you mean to say its 180 degrees out of phase, hence "split phase" Great Video :)
Is it possible to make an "ac coubling" with a grid tie inverter for off grid use?

You have to check your panel. make sure grounds are isolated to a grounding bar and no neutral to ground screw is installed.
