I think I spent around £1200-£1400 on panels, trays, roofing underlay and battens. The trays are designed to be used in roof and pretty much replace the cost of roof tiles. Personally I feel a fantastic idea for roofs

Which part buddy?

⁠so sorry how much were the panels ?

@@superdannyj£72 each from Midsummer Wholesale

@@TheOfficialBatteryManthats good and what make model are they please ?

The problem is you start looking closely in places and you see more areas that need your attention. I’ve been exploring the idea of having solar panels on the passage. But it’s quite dark. Oo what’s batteries you built?

@@TheOfficialBatteryMan Yeah, I wanted my inverter and battery outside the house, but undercover, so like you, I have them in the small side passage. Problem is I had to have the roof redone first, because it wasn’t fully water tight. Then I skinned the inner roof to hide ugly rafters and cables etc 🤣. I built Seplos Batteries from FogStar. They’re based south of Birmingham in Reddditch. Had my battery cells from NKON in the Netherlands. I’ve got 2 kits built now. I have a tutorial series on my channel because the instructions available are rubbish. Just finished the series yesterday. I left out all the grunting parts of hauling 130kg down steps, but it’s informative for people who buy these kits. I’ll be waiting for your next video. Interesting stuff. Note that your battery is LFP, so pretty safe if you decide merge the garage and side roof, but unless the garage roof needs replacing anytime soon, I would just put new wood up there and double wall poly as the easy way. If you don’t mind losing light, do a fibreglass roof and stick in a roof light. Will help maintain temperature for batteries later.

@@GaryMeatsLife i’ve been trialling a light blocking solution with a temporary cover and I don’t think I want that. It’s probably gonna be the double wall poly sheets. I wanted to see whether I could put solar panels in place of the poly sheets but it’s already north facing and dark. There won’t be a return. I think you’re right. Leave the garage roof and just reinstalled a better side passage roof. Nice. I’m very aware of Fogstar. They are great. How do you find the kit? I’ve also purchased cells 18650s form NKON. Thanks for sharing. Will check out your video

@@TheOfficialBatteryMan The FogStar kit is great and they were super to deal with. I had 2 different issues with each kit and they resolved them with minimal fuss. The assembly instructions are terrible though and Seplos have let people down on that front, which is why I made my video series. Lots of people like me need a simple guide to put these things together without blowing something up. I just about managed to figure it out with help and i'm an Engineer! NKON also great to work with. I picked up 16 prismatic cells from them in July when I was driving to Germany and back. I managed to get them all into the lower boot and frunk in the Model 3. The Seplos kit went on the roof rack on the return trip. Should have made a video 😅

⁠@@GaryMeatsLife sounds like my kinda adventure. Was there a big price difference between Fogstar and NKON. I’m not sure if they are still doing their big Friday discount. There wholesale prices are consistently lower for larger orders. Do you think it would be worth me mentioning to Fogstar that customers are reporting the seplos instructions could do with improving?

Wa-go. Wey-go. Not sure why I struggle with the English language so much 😂😂

Sure thing. Faster EV charging and energy arbitrage. So I’m limited on how many solar panels I can fit on my little plot. Sad I know. I’ve cried myself to sleep over this fact 2 many times. .. So next best thing is fill batteries at cheap times and sell back at more expensive times. Provide the grid with energy at times it needs it. And providing me a profit on each kWh. So a way to transfer energy between the property and the grid faster. The project is seeing if this can work out. Or if the scale is still 2 small to make it worth it. Commercial companies exist doing exactly what I’m describing. But can it be done at home …

@@TheOfficialBatteryMan I hear you on all that. I have 6Kw of PV myself. Wanting to do the same with batteries. I'm thinking of the fox 10.5kw inverter. But that's all single phase. Thoughts?

@@davidcassidy2944 are you in the uk? Intending to use it off grid or on grid? 3 phase is over board if your not using more than 20ish kw in the uk and you can plan your usage around that to not peak. Not much experience with FOX. I hear the app can be a bit finicky or slow. But I’m intending on using one of there inverter and will share on the channel my thoughts

@@TheOfficialBatteryMan yes I'll the UK. Yes we only peak at about 15kw. Daily about 50 to 85kwh. But yes if you are getting 20kw PV and wanting to export it all 3 phase makes sense. Looking forward to the next episode, keep it coming!

@@davidcassidy2944 if you can wait I’m hoping to cover all of your questions in the next video. There comes a point where 3 phase power turns from a want to a must. But you want to calculate your current and expected demand. Then consider whether you can manage on single phase both now and into the future as we no doubt increase more electric loads. My research seems to lead to 17kw solar inverter is the highest people have single phase in the uk. With out rubbish weather oversizing solar is a good idea to provide energy more of the year

Yes a DNO install. Next video Is a full video about it. Can’t wait to share

I want 3 phase at my house as I run two EVs and can’t charge effectively at the same time. Personally, imo all new houses should have 3 phase, solar and battery storage.

@@stevemann6110I couldn’t agree more. You need builders to be thinking. Let’s create these houses for the future. They are also trying to please everybody. ‘O will we sell 100 houses if we put heat pumps on them all.’ Solar is a no brainer. They must be able to get panels for a steal in bulk. They have come down so much the last few years. Even an oversized 3.68 KW system making use off all roof space using in roof system… saves them money on tiles too.

Unfortunately from my experience the builders do the bare minimum to meet building regulations. The only way to get 3 phase, solar and battery storage in place on mass, is a revolution in building regulations. Which I believe the government doesn’t have the balls to do.

Ooo … How would you have done it? It’s hard to give off every angle without showing off my neighbours and the street. In an ideal world building a battery hut down the garden or my second idea the battery trailer. 4 batteries on a trailer which could be made pretty and found a permanent home. They are not exactly light to man handle to get to the back of my house for a hut. And a battery trailer to my standard is getting expensive 😂 💸💸💸 My battery had centre to centre of 144cm

@@TheOfficialBatteryMan A Franna would’ve worked much better as the hook is attached to a winch (I’m in one now). Not sure you get those in the UK though. My other thought was why not attached a lifting point to the side of the house, then you can just hook up a chain block if you ever need to lift it out again to service a module..

I waiting for EV batteries to go up in price and people to not be able to work out why 😂😂 thanks for saying hi and sharing your story 🫡

North facing in shade most the year. The best I could get is reflection from the clouds. . . But it is for RUclips hmmm

There are people that do these projects using the inverter entirely off grid. Charging from solar and discharging through battery when needed. Needs to be done inline with the electrical regs near you. Would recommend getting an electrician on board for the grid bits. Can you use your panels with a grid tie inverter? Or is that what you have with the Solar Edge?

@@TheOfficialBatteryMan yes the Solar Edge is my way to the grid. I have solar optimizers on each panel. Solar Edge 400v 10kw battery is about $7k plus installation. Tesla model 3 is about $5-7k and 60kw.,but probably usable 40kw. So, I can generate about 20kw a day over 5 hour average generation. I just need an auto switch to cut off back feed to the grid when it goes down.

Throw that crap of solaredge inverter and buy a deye or just connect the deye in ac-coupled way

Bifacial panels is a fantastic idea. They could look really neat. The direction they would face is north north west. So in shade most of the year bar the evening in June and July

This sir is a good comment

Around 10 wall anchors in total. The weigh is through the floor. The battery balanced on the feet before it was secured back. Originally I thought about retaining it entirely. Everything is m12 .

The gentle hum soothes me to sleep 🛌 😂👌

😂😂 love it

You are indeed my friend! You are indeed.

I really need to stop painting myself as the incompetent fool. Or maybe more incompetent. What popcorn? Sweet or salty? 😂😂😂

Well that’s a shame Brian Wrenn. I won’t mention you then 😂😂

I want to try to keep to a 2 week schedule. I’m well excited for releasing the next video. The utility company has paid a visit and carried out my service upgrade

A peak of 2500 instantaneous watts. In not so sunny August I’ve been seeing 10kWh a day. That’s more than half my home usage. So I’m happy.

What did you go with? Thanks for sharing

I try to replicate your project(and many other's). I bought a model 3/y LFP pack, 2022 made. I've almost put my battery pack in place, i have one more step to climb, this will be "manually". I have all the accesories. Your detailed list to buy was very usefull. Thanks for that!

Thanks for hitting the comments

@@TheOfficialBatteryMan No worries. You're doing a great job. I want to do the same at home.

Thanks bro

@@TheOfficialBatteryMan when is the next one 😁

Total? You will have to wait till the end for the total cost of the project. But the battery itself cost me £3800

@@TheOfficialBatteryMan that's alot of battery for not alot of money.

Very good shout on spacers for torquing down the battery. Thank you. 🙏 Some more info. The passage/ garage is northwest side of the house. So only sees sun in summer evening. But it could be interesting to report to RUclips how much energy can we get from a panel in shade most of the year. And I’m trying to find spaces for solar panels everywhere I can without it looking messy.

@@TheOfficialBatteryManyou could figure out what length spacer is needed and cut up some steel pipe to those lengths, it’s too much space for washers.. just use pipe with an inner diameter at least as large as the bolts.

@@mwolrich I had a box of washers. Took @allan80supra advice and used them up. 5 m12 washers per bolt did the job

Thanks for letting me know there is a person behind the viewer stats

O wow. Nice one. Are you using the battery emulator project or another BMS?

@@TheOfficialBatteryMan Currently no BMS. I set the Solax inverter to Lead Acid mode so it doesn't need to see a BMS. Hoping to get a BMS soon.

@@alibro7512you configured for low voltage ? I’ve got on well with JK BMS in the past

@@TheOfficialBatteryMan No, that's the problem. The pack is 60S so I set the max voltage to 237V which is 3.95V per cell and the minimum to 210V which is 3.5V. This way I should be well away from the max and min voltages for the cells to ensure none go over or under voltage. This still gives me around 15kWh which is plenty for my house and I can even use it for an hour or two of EV charging. Once I get the BMS operational I'll be able to use more of the batteries capacity but for now I'm happy to be conservative.

Did you declare to DNO without MCs / installer?

In my very short RUclips journey so far a month between content is a long time. Thank you

@@TheOfficialBatteryMan I've been making YT videos for a few years now and I can recommend you don't try to keep to a set schedule. It gets old very quickly. The best way is when you're doing something interesting make a video of it and enjoy the process.

Home batteries are now commonplace but I don't remember ever seeing a question about them when booking home insurance. If it was something insurance companies were concerned about they would be asking about it.

Feel this needs a full Video

Hi good question the simple answer is ‘Yes’ the more complicated answer is a question. Why run it off grid and not make use of the grid? Length of cable run from the main house? The loads you describe use both lots of power (shower) and lots of energy (hot tub) this means high powered inverter atleast 10kw and lots of battery storage. You would need a decent solar set up to maintain that. Does your property have a decent amount of space?

@@TheOfficialBatteryMan Thanks for the reply, he main reason for containing the cabin etc is because of the distance from the main property being about 300 meters and the electric meter being the opposite side of the house and the cable would be a nightmare to run because of tree roots etc, a major problem, oh and also the house is thatched and listed.

O wow. Got anymore details…

Exactly. Possibly a small loss in efficiency with heat but panels get hot in the sun regardless. I really think all new houses should come with in roof panels installed. There isn’t much difference in price between tiles and trays plus panels

I would agree 6 months later I realise how much of an idiot I was on camera 😂😂 least it provided the world some entertainment.

An airplane can look scary to people who don’t understand how flight works.😂😂 trust me bro it’s ok

O dear. I’m sorry to hear that. Lipos can be crazy when they go. A lot of energy being stored. But we also store that energy in petrol and other fuels. The batteries I’m using are LFP so inherently a little safer. They are outside and are being used at a far lower current than they were designed for so cooling and warming shouldn’t be an issue

If I shave my moustache off they will never know it’s me😇

3 phase video is on the way. The process has been slower than I would like but there is a positive I’m not willing to reveal yet. That is a lot of money. Anything you can do to reduce the price? Digging a trench with a conduit ready for the power company? That’s a cool idea. Although I can’t see how they would stay in sync if you were to use them off grid on separate phases. I’m sure someone who has experience would have something they can share in the comments

@@TheOfficialBatteryMan I have 3 phase & waiting patiently to see what you have planned. I'm hoping to use the same LFP battery with 3 phase 10kW hybrid inverter, maybe Solax or Fronius.

Very nice

As a man of many unfinished projects .. we shall see 😂

5:10 619 mm ☮️

I wouldn’t go over 600mm centres if you can

If my converter is correct, 24” = 610mm I prefer 16” (410mm), but with solar panels being mounted you get a lot of stabilization. 24” (610mm) should be fine as long as it’s thick enough for the length of it. Here in the Sonoran desert we get some frequent Monsoon winds hitting 100+ mph. You have to take that into consideration as well. All of my posts are steel, rafters are steel with the panel mounting rails out of aluminum- they’ve held up to 4 years of monsoons.

Excellent. There are online roofing building calculators too. Sounds like you have it sussed

O yes. I actually don’t see there being much need for people to swap out a couple year old Tesla battery in their cars. So presume the used market is being propped up by second life users. Just a theory

The capacitor is just connected janky into the end of the Tesla connector. It needs to be on the output of the battery. It can live inside the battery housing or anywhere before the inverter. I’m putting mine in with the fuse isolator after the battery

@@TheOfficialBatteryMan Thank you for your replay.

You can plug in a Lilygo in with the software from the ‘Battery Emulator’ by ‘Dala the great’ on GitHub through the x098 port. This would give you the cell voltages highest and lowest showing the mV imbalance. This is a good indicator of health. The battery would also need 12v powered through the x098 connector That pack is LFP and very similar to the one I’m using. I’m using revision D. I will add a link to the project instructions on the GitHub in the description.

When you consider it can only take one cap to go bad and knock out BMS. Anything is possible when it’s for RUclips 😂😂

If only it was that easy. One day living off grid with hydropower and multiple EV batteries in a shipping container. In the meantime …

Any inverter connected to the grid needs to meet certain standards. But it’s very dependent to where you live.

Thanks for the comment!
