I've been working for a solar company in the UK for a few months now and we are really happy with Sigenergy. We recently left a job and had a warning flash up for an error so we went back. We couldn't diagnose the issue so we called Sigenergy. They looked into the issue after we confirmed the installation was correct. Turns out the earth rod originally installed, 15+ years ago, on the house was 20mm short of the depth required. All worked out by the smart "ai' hybrid inverter!
A bit late for this one, but a suggestion for a future install. Our Sailing club has concrete tiles on the roof and had Solar panels installed recently, the installers went for an in roof system so all they had to do was remove all the tiles where the panels were installed, added the tray system, then the panels, the result is very neat and no danger of a leaking roof, no bird proofing needed plus we now have lots of spare tiles!
I am just starting to build three 50kW solar power systems on the roof of a large farm. 380 panels and I will do them alone, or well, the farmer's son promised to help lift the panels. Wish me luck.
Hi Jordan, I'm not sure about what you said about the three-phase inverter being the only one available, Victron has been doing that for years in fact I could turn my two "in parallel inverters" system into a three-phase just by adding a third inverter. I am surprised not to see more Victron equipment nationwide, especially among expert and dedicated technicians like your good self. Thanks for sharing this one more experience with us 🙏
@@shuhel02 backup was the word that caught me as well but, in all fairness, I think Jordan meant backup as well as providing "off-grid" energy, he didn't mention it there but he did later on. However, I think Victron is miles ahead being in itself fully configurable and only now other companies are trying to emulate some of its features.
@@VinoVeritas_ I'm sure he's not all like that however it is pretty obvious that he is profit-minded having seen his charges but I like the way he works and the way he presents his company, not many businesses are as organized as Artisan Electrics company is.
Perfect example of when in-roof solar makes sense. With that much solar covering the roof, it would be quicker to strip the slates and just reslate around the small bit of roof that has no solar. Those brackets and flashings look a right pain in slate!
😀 I was thinking exactly that when I saw the layout, I've placed mine on the ground but if I had to do a roof-mounted system I would definitely remove the tiles and integrate the panels in the roof.
That's what my sister did recently. The main ESE facing side had escaped attention, old slates and the oldest section needed felting properly for the first time so she has in-roof panels in some sort of tray and the best of the slates all round the edge. As it's the frontage, it looks really good. A few bonus panels on gables at the rear doing SW & WNW top up. Nice big battery but can't get them out of their hybrid only cars.
As others have commented the Victron ESS takes some beating. 3* quattro setup 3 phase with Byd battery's. Scalable to any size you may realistically need, very robust, two ac inputs so easy to integrate diesel genset, modbus ip coms with fronius inverters for well behaved throttling of solar if battery's full and ac load low. Also high continuous and peak power and the byd battery's are happy at high c rate charge and discharge.
There're plenty 3-phase hybrid inverters with full 3-phase backup. Some, like Deye/Sunsynk, even provide 100% unbalanced output with max of 50% of nominal power per phase. For example a 12 kW unit will supply 6 kW to loads on one of the phases and remaining 6 kW can be split between remaining 2 phases.
Hi Jordan, I am so happy to see you choose Sigenergy, it is 100% the most cool and advanced battery option with 5-in-one feature in the UK! Great job! You are absolutely the high level as expected !👍👏🎉
We were super impressed with the Sigenergy battery and can't wait to use it more in the future. Make sure to come back next Monday at 8pm as we will be uploading a whole video based around the Sigenergy battery.
@@artisanelectrics As a purchasing, I did a lot of research work on so many different brands, but Sigenergy is the only one I would like to recommend to you at this high end level. Indeed, I think the brand should be thankful for your choice, since you have so many followers online, and it is actually a great channel for people to know its name by your excellent work.
Greetings from Germany and apologies for my bad writing. 3-phase-systems with 3-ühase-backup are very standard in Germany. You cpuldt try Fronius-inverters from Austria. They do single- and 3-phase inverters with a full backup option. SMA inverters from Germany also do single- and 3-phase inverters. Although they don't do a perfect 3-phase backup, Their backup are 3 single-phases. So 3-phase motors won't work. Both companys work with byd batterys from China. A big veriety of storage from 5kWh up to absurd amounts. And the batteries are stackable to have flexibility. Thanks for the videos and all the joy they give to me.
Skill Builder aired a recent video where the home user who designed an app to manage his solar system and battery pack .He actually makes money by importing from the grid at one price and exporting at another by being billed at different hourly prices during the day.
The Victron system is rolling out a similar feature as far as I know, it also includes predictions based on usage history to make sure you have enough stored when you are likely to need it and the prices are high
Bifacial panels really work much better when you have light getting into the panel from around the sides. Having it flat like this on the roof will increase production by only a little bit. Also, the cells themselves are bifacial, there aren't 2 cells back-to-back. This is still a great install, and of course if you get only bifacial panels you might get better prices anyway.
Very cool job. 👏 Ps. Might want to look into flat roofs. You had scaf on main roof but no fall protection on the flat. Can get portable barriers such as Kee Guard Safety Rail or mobile man anchors. (Sorry! Just done the height courses 😂)
Lovely stuff that job 👍 Hope you used end caps on the uni strut always use galv spray and strut end caps in commercial especially in plant rooms, the little things matter. Great job.
The rubber feet for the Valk system should have had the plates underneath as they react with the epdm roof what you have done there more than likely has invalidated the roof warranty
Nice job to get for sure. I do the Sigen equipment as well but i only seem to get jobs between 11-14k, i can guess or estimate the cost of that job, but cant really see how it could be a fixed price quotation without a site visit, unless maybe you just add a few extra days on (just in case). Not sure if this job was a while ago but the speedfit slate kits would half your workload, no slate puller or saw needed, just a screwgun and a grinder, much cleaner finish too.
As ever, a great video....not sure who does your RAMS, but perhaps some edge protection should have been erected for the flat roof works? That said keep these videos coming, it's always good to see how other sparks work and a good place to pick up tips
Great job! Look forward to full video on this battery! Slate is always a pain for us too! I did think solar edge could do backup on three phase! Giv have got three phase AIO was coming!
Solar edge do , at least I hope so as have just had it specified for back up with two Tesla powerwalls , although the 3 would have been better . This sigenergy looks interesting but I need the inverter separate so as to avoid exterior cabling on stonework .
Have you had any clients interested in a vertical bifacial array? Seems sensible now that power is so cheap during the regular solar peak. Seen some promising results from other youtubers, also due to the super efficient cooling of vertical panels.
That plant room is awesome! Also see Uviquiti networking gear :D Question, though: In the Netherlands, it is mandatory to earth/ground all rails and (indirectly) the panels, and have the earth wires ultimately coming together at the common earthing of the electrical system. Isn't that mandatory in the UK?
Thanks Jordan, an interesting vlog. How thief-proof is the Transit Custom, as this is a real world issue that van manufacturers need to address? From experience.... don't unify your fleet to one brand and model. Have two in case of a recall issue which will leave you without vehicles. How does the solar skirt affect the bifacial production of electricity?
Why not east/west panels on the flat roof? With that setup you don't need spacing between to panels to prevent shading and it gives you a bit more enery(or at least consistent) on all days that are not sunny with a clear sky.
@@ShaunMcDonaldand the winter you want the most capacity from the panel because we have little light. Probably way too many panels to suit demand in the summer but should provide enough in the winter to keep batteries topped up.
In our city they used steel nails and the slates started falling off the houses and hitting cars and basically wrecking shit. I always wondered why they didnt use stainless or copper nails, now I know they shouldve...
The angle of the flat roof panels is very low particularly if they have offgrid aspirations. 40deg is usually specified for optimal winter production, but I guess here they are grid connected and won't be so concerned about low winter sun.
As ever another great video. Some serious budget needed for projects like this. PV Ultra cable. Can it be buried? Reason I ask is that I recently had some extra panels & another battery added to my existing solar system (installed 1 year ago). As part of the new install I was told that the existing SWA cable from the roof panels to the inverter had to be replaced because it was not double insulated (so why was it installed originally?). The old SWA cable was neatly buried under gravel down the side of the house so was nicely out of sight. The new PV Ultra cable is double insulated but I was told it could not be buried so now I have a big black cable running down the side wall of my house 2m above the ground. Not ideal & a bit of an eye saw IMO. Your thoughts would be appreciated.
A note on systems that supply 3 phase - most systems can do 3 phase * (you do get specific 3 phase inverters - eg victron) The way they do it is by using 3 units tied together - each inverter goes onto each phase and they keep each-other in sync. Then by using multiple smaller units - you can get higher available power in total, but while also not maxing the total load of each unit (or the full system) eg - 9KVA system may have a peak of 15KVA for 10s (motors etc) But, if you do 3x 3KVA - still 9KVA, but each inverter can peak to 10KVA, so a total of 30KVA peak ability. So yea, pro/con and overall for space - a single unit is nicer ... the 3x3KVA would be 3x6 total inverters ... so a lot of space This is where singular 3 phase units are nicer, since a 3-phase 3KVA (eg for ref) - x3 for 9KVA - but 9KVA in 3-phase vs 9 total units .... a lot of space saving
I have seen whole roofs blown off in a gale. I would always strap the system down by attaching straps from the array to the side of the building. Are you sure you are following the building regs?
Genius have a new flashing that is a game changer on natural slate roofs and it’s called Speedflash. No ripping and removing any slates except for the first one to find the first rafters and then mark the centres and cut in with a grinder.
i don't think it's advised to anglegrind the concrete tiles. instead there are special tiles that are made to be the mounting points for the solar. (50€ a piece is still cheaper than a leaking roof...)
How much did it cost for the installation? Huge amounts of electricity 😂 what's the actual projected estimate? Details on the payback period please.... I bet a better investment is to invest the money? How much would it cost to replace a slate after the installation? I was verbally quoted a lot.
Please stop letting your guys carry these panels over their shoulders. The pressure on the glass can and does cause micro cracking. I can share a report on this if you really want to look at this
you’re mechanically and logistically challenged. You may be a good electrical engineer but I’ve seen several ‘less than optimal’ mechanical issues across several videos and that’s just the ones we see ! Working so far from home and relying on ‘just in time deliveries’ that are outside of your control (imagine if Just Stop Oil blocked the route one day LOL) is not the way to do it. As you transition to the next size of company/operation you need 6P implemented and that starts by making sure you have everything you need in your hands prior to install. By doing this you will save time and money.
Great video from Artisan. What a nice project, and I take my hat off to you. I was surprised at one thing here. I'm not a lover of H & S, trust me, but no hand rail on the flat roof for your lads?
I wish YT creators would stop referring to battery storage systems with islanding capability as Uninterruptible Power Systems (UPS) - they are not. Yes, some of the systems have very fast changeover switching times but if customers have critical devices in their installation, they should also use properly specified UPS to protect these devices. And yes, I realise that _most_ electrical appliances will not be adversely affected by changeover switching times typically quoted for contemporary 'gateway' control systems. Didn't see any reference to an independent measured earth electrode. Is that in your deep-dive vid that is to follow? Maybe the installation already had one?
@@artisanelectrics if the BESS is only operated as a switched alternative source, then it doesn't comply with Reg 21 of the Electricity Safety, Quality and Continuity Regulations if it claims 0mS changeover. If it is operated as a long-term parallel source (as I'm sure this installation is), the Loss-of-Mains protection will be based on Rate-of-Change-of-Frequency, which should be set at 1Hz/s with a 500mS delay to comply with ENA-ER G99. As RoCoF typically requires roughly 6 cycles to actually measure the rate of change (so, about 120mS at 50Hz), the LoM protection would typically take around 600-700mS to respond to a supply interruption, taking into account switchgear operation.
The wall fixings supplied with most solar gear is absolute crap. Yours is a case in point - why 100mm loose nut bolts?? 50mm would have been sufficient on a bare block wall. Why not just ship with without wall fixings? Its very wasteful. I did an install recently on a stud wall, I ran shallow strut across it to mount everything to. The fixings supplied all went in the bin.
Solar madness first a nice job done only at what cost? 25 kwh inverter big? no i use a 50 Kwh inverter, now this is the only thing i have against solar. the cost of the whole instalation and the ROI, we can take two options the saving with a 20 cents a Kwh cost or with 2 cents, i say this because solar is a 50 year old innovation do you hope and believe this standing still will take a other 50 years if yes you can calculate with 20 cents if no it will be 2 cents. i am sure you will not have a roi with 2 cents, but that is the future!
