Depending on the depth of the box, you might have to put spacers under the DIN rail now to make sure the breaker faces protrude through the opening on the front, If it were me I would have just cut the opening so the box fits through, and secure the back box down to the shelf, then the hole box could have been set back even further. there are flush mount switchboards available as well..
Nice. I like your screws used in the sheet metal as well. We built our first solar system this year, only 500w in panels and 200ah lifepo4 batteries. This test has worked so well, and answered so many questions on a small scale that we will be expanding the system over the next couple years. We do not want a grid tied system (at least not one that will feed power back into the grid,) so we are installing a manual transfer switch and will keep some circuits on solar full time with the ability to transfer back to grid power if needed. At this point I think our goal is to have approx 1500-2000w in panels and 800-1000ah in battery. This should be a nice system setup to reduce overall grid power consumption, as well as emergency power when grid goes down. We are also looking at adding a standalone system to feed a mini-split hvac system which would supply only one portion of our home. That one is several phases down our list though
Thanks so much for sharing. It's great to read about your success. And you're absolutely right, you can learn a lot from having your own system and see how it works, behaves and... fails sometime. Great work!
Andy in EU we use 3 phase connecting bar. But maximum load is 100A. Personaly I like the most fork type connecting bar, because the fork is connected to the screw and you have free terminal for future use. About fuxe box, it is misunderstanding. First I meant to rotate din rail 90°, second I thought that use want to build your own cover. Definitely your way is better. And thank you for the video :) Small Edit: only one problem with fuxe box I see: when you have to do something with your breakers, the box won be fixed. So it means you have to take off top cover and fix the box. But this can be easily solved by two screws on the bottom.
These are DC breakers so there is no 3 phase in this cabinet. The fork lugs you're referring too are very thin and I doubt they would have a 100A or even 250A rating. Yes, the box is not fixed. It just sits on the shelf at the moment. I will see once the cables are connected if I need to fix the box or not. Once everything is installed I don't need to take of the cover any more. Unless I will install more breakers and then I have to take off the top anyway...
You can use just the fine stranded cable in connections, though you need to wrap it in a thin copper strip as per code if the lugs are not rated for fine stranded cables. We do this at my work all the time for 1500A battery connections on UPSs.
@@OffGridGarageAustralia No, America and NEC codes. Its more of a ~20gauge copper strip that's 2cm wide than a foil that is used. We use it in all of our temp systems that use flex cabling which is fine stranded ( 250-750Kcmil wire). BTW, I am an Engineer.
That’s a cool job you are doing on this project . Looks great and professional . It will take some major time to really get the battery shelf all sorted out and I’m sure we preppers will be very happy for this awesome project and the time taken to finally turn it on with the solar system for the first time with successful results . Thanks 🙏 and May the solar be with you .
It is really coming together quite nicely. All of the idea have helped you overcome design difficulties and that is always a plus. I would love to see more video on power generation from both solar to a self made wind turbine.
Thanks Peter. I think skyhooks are more the all purpose outside model of them, while airhooks are more universal. As long as they are from Siemens, they work the same way though.
Nice work, professional look! Keep up the good work. ✊ You couldn't do it without your followers. 😁 Just an observation sometimes easy to forget, don't make it too difficult to access/mount "inner" components, cells, etc, etc... It's always nice when we have space to work.
Yeah, I'd abandon the box myself -- it's quite a limiting factor. Turn the entire upper area there into an enclosure. If the box was larger, sure, but trying to use a box that creates too tight of a choke point just creates more problems than it solves. Breakers don't have to be up and down for what it's worth. Side runs buys you much more space and a far easier place to work.
No worries, left and right are on opposit sides anyways in Australia. So i wish you more luck getting the same switchboard again than me. I bought three pieces (smaller ones for 8 modules), that were available and several weeks tried again and again... and again to get the needed fourth one, until i noticed, that Praktiker had obviously no more of these ABB boxes available in any size... And other Brands look very similar, but you do not know if it really fits the hole...
These switchboards WERE standart here as well... And you are right. Praktiker does not exist any more in Germany. But here in Bulgaria they did not vanish. And if i am not confusing something, they are in Romania as well. Some years passed, since i travelled last time in between...
Hi, Are You planning any fuses for each individual battery pack ? Or maybe only those heavy duty brakers on the side of the shelf ? I'm having trouble to find the heavy current braker which will have some kind of over current protection build in. In most cases those are only heavy duty switches which are ok to disconnect hi currents, but You still have to activate them by hand. Can You elaborate more about it ? Thanks.
The breakers will isolate each battery bank individually before they connect to the vertical busbar. When we talk about high currents here, each breaker will trip at 80A. That's what I will set them to. Is that a high current? I'm using the NOARK DC Breakers fir this job, 100A for each battery bank and 250A main breaker for the whole battery. It is absolutely OK to have them manually reconnect again. If they really trip, you want to make ensure nothing is wrong or any fault has been cleared before you turn them back on. You don't want them to turn on automatically at all!
@@OffGridGarageAustralia thanks for an answer. Exactly those are currents i was talking about. And i've seen that a lot of brakers which are sold, are simple high current switches. So they are not tripping by itself due to overload (overcurrent), they are simply capable of disconnect high current when You want to manually do it. This way they act more like emergency turnoff rather than automatic protection. And sometimes they are even sold in this molded case, which makes them hard to distinguish from automatic overload protection. Can You give a hint about where best to buy those NOARK DC Brakers ?
2 pole insulated busbar may work for the double pole circuit breakers. The max current rating of the busbar may not be suitable though. 63A & 80A seem to be max current rating. A few can get up to 100A. Those current ratings are for AC not DC as well.
What breakers are you using for the batteries that goes through the side? I can't find them on your site and they appear to be 250 A or so din breakers. Looking for something similar that isn't like $800 each!
Yes, 100%. Not just because of the balancing function but also of the separate port ability to turn off just charging if a cell has high voltage. The QUC always creates total chaos when it turns off because it turns everything off.
Those 'bended' terminals look great - your English language lecturer must be a very helpful kind of guy. More like a helpful friend than a lecturer don't you think?
These are actually angled lugs. Bent would be sideways as the ones I will now get from a sponsor. There is always something in each language which you never get right 😁 And, yes, a lot of very helpful friends here, absolutely.
That is all because every country has different regulations. There are battery shelves and battery storage solution you can buy and also think about the server racks many people use.
cool! those are nice big aluminum plates! it is fun to work with thick plates of aluminum. One question is will you be installing an equipment grounding conductor to all parts of the frame and panels of the shelf? Will you be bonding it to the ground of the AC side and the negative of the main bussbar? (the horizontal bussbar on the top shelf)
I'm thinking about the grounding for a long time. As I will have several Al sheet around the shelf, they all need to be grounded somehow. There are sections in the AS/NZS Wiring standard where it is allowed to use star washers for grounding metal which may be exposed to dangerous voltages. Unfortunately, it is just a guide with no real examples when, if and how to do that. For this reason, I will probably ground them all individually with short cables to a single ground point inside the shelf. Still thinking 💭
@@OffGridGarageAustralia yea the cables would be the safest, though star washers are probably plenty good enough, how will your ground point be made? a large threaded rod or some type of bussbar or terminal block?
Yay am first to comment lol, keep the video coming. Also can you add a can-bus bms option to your jk-bms to your victron setup? I’ll like to see how you do it so I can do it in our build also 😊
Hättest noch links und rechts ne Zunge stehen lassen sollen mit je einem Loch anstatt ein ganzes Rechteck auszuschneiden. Aber leider schon ums Eck. Sonst finde ich es einfach nur geil dir zuzuschauen wie es vorangeht, mach weiter und prösterle ;)
Das hatte ich erst ueberlegt. es haette aber keinen Unterschied gemacht oder Vorteil gebracht. Die beiden Schrauben halten ja nur das Frontcover mit Deckel. Also genauso wie bei einer Wandmontage des Kastens. Der Kasten selbst sitzt ja flach auf dem Aluboden des Regals, hat also nichts zu halten. Die dicken Kabel werden fuer weitere Stabilitaet sorgen 😂
I hope Andy that you will screw those plastic boxes to some place..to that acrylic material..because now all those boxes are held only by two small screws ..and that is not good at all. also check your circuit breakers inside those boxes and you might see that they moved a bit back..not sure how problematic that will be..but better to check it..
There would be not enough space for the battery compartment. It's unfortunately all the space I have. I tried different settings and showed them in a previous video ruclips.net/video/S2_4X3Jje0Q/видео.html
Splitting the circuit breaker box with aluminum on the sides is not to code. Wires touching the aluminum can abrade insulation and cause a short. Would be better to flush mount the box and run wires with conduit through the back. Although, I don't think a plastic circuit breaker box for DC is to code either. Uncovered buss bars and terminals are not either.....so down the rabbit hole we go. Be careful with the exposed aluminum and keeping wires away.
There is an insulator material inside the box wich covers the tiny AL areas all around. Everything else will be shrouded as I have explained many times...
I think the heat theory on the stranded wire into the circuit breaker is BS. The distance is so short... Would be a good test/video idea. I also think you should start your own line of Andy's Safety Shoes - "great for heavy ground work or climbing around on a roof"
If you think a regulation is BS or not makes no difference as it is still a regulation. For me it makes perfectly sense to use a lug or ferrule with this fine stranded wire. It ensures that all strands have good contact and no hotspots occur. We're talkig about energy distribution here not just a light on a 12V battery for a camping trip.
Ich mach das mal in Deutsch da ich nicht weiß ob ich das in Englisch so erklären kann. Warum muss der Kasten vorne und hinten an der Aluplatte anliegen? Die zusätzliche Materialstärke des Aluminium und das "nicht-ineinander" schieben von Kasten und Deckel lassen die Sicherungen nach hinten wandern. Es könnte sein das dadurch ein Spalt an den Sicherungen offen bleibt da die normalerweise Bündig mit der Frontplatte in dem Deckel abschließen. Ich sehe nicht ganz den Nachteil wenn die Aluplatte einen Ausschnitt in Größe der Aussenmaße des Schaltkasten bekommt. So könnte man den Schaltksten auch noch weiter nach innen schieben bis kaum noch ein Überstand an der Aluplatte entsteht. MfG
Nein, da ist kein Spalt. Ich habe verschiedene Automaten getestet und alle stehen nach vorne raus. Wenn nun das 3mm Alu dazwischen kommt, rutschen die Automaten ~4mm nach hinten. Das ist ueberhaupt kein Problem, da sie immer noch nach vorn herausstehen. Ich habe das so gebaut, weil nun der ganze Kasten sich selbst haelt und ich keine weitere Befestigung benoetige.
I see now. your breakers are dual breakers not all singled so my idea wont work in this case with the bus bar and cut tabs. In future might be better to get single breakers so you can have all pos one side and neg the other. Or the staggered breakers.
Ah, was this comment from you... never mind. these breakers are always coming as 2 pole isolators and they have not staggered terminals. Maybe I should look at some other brands for these DC breakers to see if there is anything available. But I really like the NOARK stuff...

Nein, da ist kein Spalt. Ich habe verschiedene Automaten getestet und alle stehen nach vorne raus. Wenn nun das 3mm Alu dazwischen kommt, rutschen die Automaten ~4mm nach hinten. Das ist ueberhaupt kein Problem, da sie immer noch nach vorn herausstehen.
Ich habe das so gebaut, weil nun der ganze Kasten sich selbst haelt und ich keine weitere Befestigung benoetige.
@@OffGridGarageAustralia Na dann hast du ja an alles gedacht. Super weiter so. 👍

Ich finde eure Regeln in Australien für Elektro Installationen sehr ähnlich zu Deutschland
Ja, sie sind es in der Tat.
I see now. your breakers are dual breakers not all singled so my idea wont work in this case with the bus bar and cut tabs. In future might be better to get single breakers so you can have all pos one side and neg the other. Or the staggered breakers.
Ah, was this comment from you... never mind. these breakers are always coming as 2 pole isolators and they have not staggered terminals. Maybe I should look at some other brands for these DC breakers to see if there is anything available. But I really like the NOARK stuff...
