- Опубликовано: 26 окт 2022
- Day 4 before the big solar upgrade. Tonight, we start with the cabling of the DC circuit breakers which will connect the two new solar charge controllers to the main DC bus bar system. THis new upgrade almost maxes out my switchboard and there is only one space left now. Time to keep working on this PowerWall 2.1, I guess...
It also kept raining the whole day long. Not good...

Heya, nice to see your back doing some old hands on work again
So entertaining, thanks Andy for such great videos.
Thank you, Francis.
Francis ..I know right
Andy your cables very nice next video give little introduction about cables
Very good clean installation
5⭐👍
☕☕
Best regards from Philippines 🇵🇭
Thank you. I made heaps of such videos when building the battery 2.0. There is a play list on my channel with all the videos. Tons of information in there...
"I'm sure I've got one of these in the garage, but where?" Sounds so familiar to me!
My wife "tidies up" my stuff (i.e. hides it). I must have about four of each thing.
Yeeeeee. For me too:)
@@davidpenfold My wife does the same thing.
My wife does not enter the garage so I cannot blame her...
Watching done. Waitin’ for new video now! 😄😅
Working on it... tomorrow...
Oui ANDY comme au bon vieux temps ! cela nous fait beaucoup de souvenir et c'est agréable ! bien on continue l'aventure .
Great videos. Why would so much work it's overwhelming. I'm trying to figure out my little system and you're doing this crazy huge system. Well congratulations on getting it all going and I don't even know the words to explain how amazing it is
i love these videos, educational and very entertaining, well done.
Thanks a lot. There are a few more to come until Monday...
Short but sweet. Looks good. Thanks for sharing
No problem 👍
Nice clean work. Looking good!
Thanks 👍
Love your channel Andy, can't wait to see you mount those new PV's on the E & W roof, & most importantly how much production they're gonna generate.. in SUNNY HOT RAINY WINDY AUSTRALIA 🤣
A lot! I can tell you that now...
I like the lug connectors with the set screw, there great for the DIY folk, but they are very expensive
Well done Andy!
Thanks, Edward.
Excellent job !
That bit will show up now, I find mine when I buy a new one.
Murphy's law. I still haven't found mine yet 😑
@@OffGridGarageAustralia Next
you will have ten of them hiding out.
Looking good
nice job😀
Thanks Andy 👍
No problem 👍
I like the disconnect switches. Probably fused/ thermal type circuit protection. Test them at 50-90 % of their rated load capacity. You want to see if they burn or melt when short circuited. The protection device should be the weakest link in the circuit.
It will be just for emergency shutdown. All maintenance, I'm usually doing at night and disconnect with no load.
Muita legal seu sistema. Eu tenho um misto. Bateria de chumbo com lifepo4. Separados. Aqui no Brasil é tudo muito caro, não dá para atualizar sempre o sistema.
Andy, can you please do a video on DC breakers as there is a lot of info out there on how they are to be connected, polarized or non polarized and whether they protect bi directional or not.
For example DC breaker between battery and inverter, battery can supply and inverter can supply when battery is being charged.
Or Breaker between MPPT and inverter and so forth....plz :P
I find it interesting you did not go with a hybrid all in one Inverter. Victron seems to require a plethora of external stuff they can charge you for. As an example, a single MPP inverter includes TWO MPPT controllers up to 600V! And you can parallel many of them. Internal Bluetooth and WiFi. It simplifes all the cables and costs.
I cannot connect anything to the grid. I have a second solar system which is grid connected and on a high feed in tariff. I made multiple videos about this on the channel, starting here: ruclips.net/video/LQJZUmWDuCs/видео.html
It would be nice to know the part number of the Noark circuit breakers. I'm in Belgium and will try to find a supplier in the EU.
Snap with the weather, Except in Scotland it has rained all October.
Snap in Ireland too, very wet in October, come to think of it, it's wet every month🤔,
@@jimbobarooney2861 Yeah you wring the clouds out a little bit for us before it hits Ayrshire. We have had a handful of dry days this year 🤣🤣🤣
I wish I could get those Noark breakers in the UK, but no such luck so far.
That's weird as they come from Europe...
@@OffGridGarageAustralia it is, look at their distributor map, not a single one in the UK. I did find one company selling some of their breakers, but it appeared to be old stock and they couldn't supply what I needed. I emailed a few companies in Ireland and France, not one got back to me, I blame Brexit
Andy….you are a big help to me to understand,a lot more than a few months ago but..
I tought that the breakers are coming between solar panels and MPPPT’s and from there to batteries
But here it’s look different…
From panel to MPPT’s to breakers to busbar
What’s the reason for this or do I missed something
And also what size of DCcable,4 or 6 mm,do you use between last panel and MPPT or breakers
Thanks
Marc
Because of that DiY feeling i thought you would built the solar with andy 2 for the hole summer but ok much work. 😅 Will the electrition also come into Andys Garage 🤪 and will change everything 🥳
I've explained the reasons for that in one of the previous videos...
andy are these your typical 240v electrical fuses you use?
These are all DC breakers, not 240V
Hi Andy, as a novice off-grid user I have questions related to securing the solar panels. I have 6 panels of 360 watts (Victron) which are connected as follows: 3 panels are connected in series, the other panels are also connected in series. I connect the two strands in parallel. To fuse these 6 panels I would like to use fuses but I don't know what amperage they should be. The six panels together have an open terminal voltage of 142.29 volts. Can you help me out which fuses I can use for this?
Many thanks for the educational and fun videos. You are a loyal visitor in my living room when I watch the videos :).
Greetings from Belgium

Twice Miss Piggy in one video!!! Jo, is denn heut scho Weihnachten? 😀
😂
Are the breakers only used as switch or also as fuse?
Mostly as switches for emergency shutdown. It also isolates the MPPTs form the solar site.
What's the purpose of using 35mm2 cable on one side and 25mm2 on the other? If 25 is sufficient why use the more expensive one on the other side?
That is part of the whole battery shelf design to stay flexible. I may upgrade the breakers to 100A at some stage.
@@OffGridGarageAustralia I see. But then the 25mm2 would be too small, wouldn't it?
It is because the cable length and diameter have known current carrying capacity based on voltage values and associated losses due to resistance and thermal expansion. Basically, he subscribes to the prescribed data of known wire gauge standards. In this way, he will accomplish the number one goal of minimizing faults and losses. In his demonstration he chose to use 35mm lugs on 25mm cable even though he had 25 mm lugs available. Why? It is because the rules set forth a discernable outcome compiled which contrasts technical experience in lieu of circuit integration and the integrity therein. In practice, the engineer will experience these limitations during practice conversely the engineer will miss and fail to identify these during the design phases.and so the practitioner trump's the non practitioner in this way. No one will write it in a text book....it is why you can be great! Quite frankly, you draw a better question as to the decision to change from the 35mm cable coming into the breaker too the 25mm cable between the breaker and the charge controller. Excellent question indeed! The answer lies at the circuit breaker where a decision towards best practices ensues # integrity!
@@anthonyrstrawbridge That is not the case. As explained, I have used 35mm cable from the bus bars to the breakers and 25mm cable to the MPPTs. Both cables have the appropriate ferrule crimped 35mm and 25mm ferrule.
Using 35mm consistently from the busbar to all breakers (even the 10A breaker is wired with 35mm at the input) makes it far easier to replace a single breaker to a different value when requirements change in the future. In such a case, I can just replace the breaker and don't need to replace the cable.
It's a 63A breaker I'm using so even a 16mm cable would be sufficient. It is not only the current carrying capacity of the cables you have to consider but also the voltage drop across the cable depending on the length of it.
whats the size of this cable?
35mm it would seem, since he keeps using 35mm crimp connectors.
Yes, 35mm from the busbars to the breakers and then 25mm to the solar charge controllers. I've put a link in the description
Hi Andy, sorry to message you here but there seems to be no contact for you on your website. I have received a request for shipping and handling charges from the off-grid Garage and need to clarify if this is genuine as I think I've heard you mention before that you never send requests. Many thanks 🙏 and congratulation for your precious videos
Hello friend can you please help me out and advise me on a good quality BMS for my enduro stealth bomber ebike which has a 72v and 48ah battery and the controller is a sabvoton svmc 72150 i
Have seen a few of your videos and you know about BMS please can you give me some advice on what would be a good match for my ebike thank you so much.
Never happy always exspanding your system....
Tobe honest I'm same......finish one bit off.....
Then think of the next upgrade....ha ha
I think I'm done now. With this system. It is maxed out and there is not much space for any extensions.
@@OffGridGarageAustralia ha ha....
Least your honest Andy.
I'm about 3yrs behind you, me and a friend have just got 50 260w panels, so some of them be going up on my off grid shed, also just waiting on new cells to arrive so my big upgrade to start.
Buy new or spend hours looking. Keep all drill bits in one box now.
Who keeps all of their bits in the boxes they came with?... definitely not me, they're all pouched.

You have too much money my mate all most of all my money goes overseas to feed and meet the needs of my Filipino family and another amount goes to those who can't help themselves and they can't repay me back either that's The best way to give anyways I can't do what you do but I will get my rewards in the next Life in heaven amen. I do like what your doing but I can only dream.
