The linking of the banjos is predominantly to maintain long term integrity and reliability of the the earthing of the cable armour. More of a best practice installation work rather than a specific regulation or there may be something within BS7430, would have to look that up though.
Utility companies around the world seem to share a knack for complicating matters, even after being privatized in an attempt to enhance service and foster competition. Thanks for the video it is most enjoyable and informative.
I think the banjo connection is required because steel enclosures have a tendency to rust especially where there might be capillary action between the gland and the enclosure creating conditions favorable to rust and high resistance. The paint is going to be damaged there, both by drilling and by tightening the gland so the steel will without doubt be vulnerable to corrosion. The gland and enclosure are also dissimilar metals that can cause galvanic corrosion that will tend to attack the steel more. Bonding the banjo to the enclosure should almost eliminate galvanic corrosion. Banjos are made from corrosion resistant metal, ideally the same metal as the gland.
since your last video got taken down nad you replied to my comment i just wanted to tell you, that I love your videos and i hope you keep up with that great content👍🔥🔥
Remote rural off grid here Australia what an amazing system indeed don't even want 2 consider the cost . Nice car collections indeed oozes money I guess. Like the way you run the sponsors adds in well done .
What’s the plan for connecting the immersion diverter? usually the CT clamps/monitors go round the incoming mains and the AC solar to monitor what is required by the house and what is the solar PV generation. In the Sigenergy the PV is Dc coupled so no AC PV only cables , so just wondering how to connect the CTs?
The 1667 thing was explained very well! I always knew it was to do with 30ma and touch voltage but couldn't actually tell you why, I just knew it was to do with it 😂 I am still an apprentice so let me off lol.
Why are the bus-bars non insulated on the gateway ? I have seen this used on several projects and asked this question, we install many control panels and commercial switchgear and all are insulated, regardless of key-tool-instructed personnel, surely they should be covered.
Awesome job Cory. I think for my own peace of mind, I'd have removed that top row of breeze blocks. They look so loose. I'd be afraid of them falling into the new kit below. 😮
Great video. Solar cable should not be on metal. IET guidelines. Should be plastic. But great video. I did one lately in Ireland, on our own place, two supplies, two inverters, ground mounted, 80 metre runs, 7 fuse boards, batteries etc. on my own, would have loved some help.
I'm curious about your unistrut angles, do they hold up well? Cracker idea and i would love to use that technique but i wonder about the integrity of the bend
If only a can of pringles was still 2 euros :D now here its almost to the 3,5 euro mark and that is ridiculous...havent bought one after they became expensive but i loooove pringles
Double check that whole divert export thing... woth the octopus export and night time rate you can buy at 7.5p at night and export at 15p making it more cost effective to export rather than store, which is pretty mad. Might not apply to such a huge solar farm tho...
I watched your previous video about the UPS installation before it was turned members-only and it was actually the reason I subscribed. So I feel like I have to ask, was it intended to be members-only originally, or did something change?
How unfortunate 😢. However, hopefully you'll get more people in (like me) who happened to see it beforehand and decided to take the plunge with you. Keep up the content and thank you!
Cool install Cory. Question, how does Inverter, MPPt and battery storage cost compare the Victron Inverters, with Multiplus ii 10 Or 15k per phase, (100A changeover switch built in/full UPS) RS450/200 MPPT and/or Fronius inverter with Fogstar 15.5KWh batteries BMS and heaters built in. The DC side is common and you can add up to 15 of those batteries for £2k each giving you 230KWh of battery storage. How much battery expansion in capacity terms do you have there?
RE: The main 100mA RCD...one of the biggest issues with RCDs is that each circuit has its own earth leakage. In a domestic property, a split load board full of modern electronics can often end up causing a 30mA RCD to trip. How many RCD and RCBOs are feeding into that 100mA unit? Does the cumulative fault current exceed that? Regardless, unless that 100mA unit is feeding an edge circuit, it could potentially be too high. I'm waffling but what I'm trying to say is that the feeder RCD should be of a higher current rating than 100mA (as long as it's not directly inline with a circuit that people interact with) and that individual circuits should be on RCBOs.
The three phases were joined inside the UPS as it was single phase capable too. He blew 2 isolator switches before realising. He tested everything so opened the ups and saw the phases were joined inside. Removed the bonding plate and resolved the issue.
My permission to post that video was revoked last minute by the company where I filmed it. I could have left it up, but I wouldn’t want to get the amazing gentleman who allowed me to film in trouble, it’s only allowed now as a members only video. Genuinely gutted, as it got 140k views in under 48 hours!
@@corymac Thanks for responding Cory. When you said what industry it was in, I was genuinely shocked that you were given permission.

@@samkeizer6654 Actually phase jumper were clearly visible throughout, he didn't read the installation manual with diagrams which clearly stated this.
The batteries are only 0.5C Charge/Discharge. Because every battery is a self contained unit with its own BMS you can add the battery capacities together and divide by 2 for the Charge/Discharge Rate. Those 2 x 8kw = 8kw Charge/Discharge. I wondered what size Inverters you had installed??
@12:30 , Am i alone with the impression, that Cory looks like a young Morrissey ?........."There is a light that never goes out" = photovoltaics Song :-)
23:00 You used the word "discrimination" with reference to using 100maA RCD up stream of 30mA RCD's in the downstream DB's. Would a better term be "Selectivity" ? As you want the 30mA RCD's to provide the protection in potential fault area's without effecting the whole property.
I work with Telecom Lithium batteries and they have a 'must be charged by' date on them on the box, so they don't go beyond a certain self-discharge voltage whilst in storage. If it's been that long, you might need to consider somehow charging them.
You bond all the swa’s up in the board to one another as you can get corrosion on the board, therefor loosing your earthing. Reason I was always told anyhow.
i am always amazed at how the power iis delivered into the house in the uk, just a board with a fuse and a meter on it... btw, we use normally 300mA Rcd in such a case here but 100mA is a good solution too
We use the PE as the main safety and RCD's etc are considered secondary safeties. 1667ohm would be way to high here. We aim for 1,5ohms on the rod, and max 166ohm if ALL circuits are RCD 30ma protected.
@@corymac That's what i keep hearing. I was interested in a DIY install but i can't make the math work out even without labor.

A fantastic start to a Friday. What could possibly go wrong now. 🤔 😂😂👍🏼
That leveling bolt for the battery base is going to have a huge weight above it, I would have wanted to spread the load a bit.
The weight is actually assisted by the back mount brackets

Love the video Cory. Am I going crazy or did you delete a video recently?
I had to, the place where I filmed it withdrew permission 🥲🙃
How far off capacity wise running the house "off-grid" until the 3 phase connection could be done?
Very close, but I just can’t risk it for now
Hi. The Sigenry system looks great. Do you know if they can do a 3 phase
100Kwh battery stack.?
Pretty sure they can! Give triple solar a call, say Cory from ØY ELEC sent you!
Will do. Thanks for the quick reply. Great content. Keep it up.
"We want to try and achieve discrimination" is so bad out of context 😂 im sure thats why they changed it to selectivity 😂
