Worth knowing that Victron Multiplus has a protected and non protected outputs to run part of your house in case of a power cut. I’ve made a video showing it.
Great video guys - alway interesting. Thought worth sharing that Tesla is not the only system that is capable of running a house if grid fails - Victron inverter chargers are very capable of doing just that as they have grid pass through built in and grid pass back if wanted. They can also be run in tandom for split phase systems off a single battery system. Essentially a UPS for a house.
You don't _have_ to depend on a Tesla PowerWall + Gateway if you want your battery to power your whole installation in island mode during an outage. In the UK, as long as the battery/inverter system is capable of island operation AND the installation is compliant with ENA Engineering Recommendation G99, you could do it. Bespoke interface protection and switchgear installation plus commissioning would cost a few quid but if you can afford a 23kWh battery, you might be able to afford the interface too.
Dear Artisan Electrics, how much will the customer charge for one mega watt of electricity exported to the grid? It would be great if you can let me know-Or anyone else who knows you are all welcome. Thank you
What do you suggest for a Neutral when youve lost all grid incoming? Dig up the feild and install both N+E for 50m? + switch gear to isolate it all when back on grid. More to it than first appears i think
I had assumed that all battery systems were capable of running the house in case of a power cut. Pleased I watched this as it's definitely something I'll keep in mind when we come to get our PV & battery system in the future.
Hello friend, we are a lithium iron phosphate battery factory from China. If you are interested in cooperation, please let me know. We are looking for distributors in various countries around the world.
You don't need Tesla, just an automatic transfer switch. There are a few options for UK domestic, some even allow a switched trigger remote to start a generator so that you can input when solar is too low, mains is out, and battery is low.
Here in the U.S. In my opinion... a "Grid assist" with properly sized panels and batteries is the ONLY way to go. The power companies here are screwing grid tied customers over in many ways. Use the grid as the "backup" power if the need arises. Nice install!

Victron inverters can run from battery when the grid fails and as they are grid forming they will keep any solar inverter running stopping the anti islanding function from kicking in, only down side to this would be the breakers in the inverters have a max disconnect which i think is 50 amps so no good if you run 10Kw showers, this is the system i have in mind, Victron multiplus 2 5000 VA with 14Kwh battery and 3.6kwh solar (solar already present) the Victron also has 2 power outputs 1 for main loads and 1 for essential loads, essential loads are effectively on a UPS, Victron inverters also have built in relays so you can control additional energy diverters, lots of options but they are on the pricey side of the market
I've now installed 28kWh of Pylontech batteries. 8x 3.5kWh batteries. Very simple. Very cost effective. Installed in the loft with a 300kg structural platform.... The system is basically plug and play. I got a local electrician to install the new circuit for it. Very cheap. Not an overpriced "Solar/EV/green" energy quote. No need for an apprentice to help pull the cable up into the loft either. 😉
12:55 Not many power cuts, but the neutral going down seems like its an issue. With all the PEN fault detection required because it happens so often there! (speaking from someone in the USA that doesn't have that issue normally.) 🤠👍 Looks like a nice system, keep up the good work guys, always fun to watch your videos and see how things are done over the pond!
Really when you install a battery system of this size you would Really want grid down power for at least essential loads. This client has loads of solar to. I'd be looking into Victrons range of products. There Multiplus and Quattros are fantastic bits of kit.
SMA inverters also support automatic fail-over to full house battery backup, up to 24kW of power (3 phases of 8kW) (The Sunny Island series of inverters) Unfortunately, they're also hard to get at the moment, but certainly not 2 years. You're also way more flexible in which batteries you use.
But in the UK, full battery back up would be 23KW on a single phase. There's only a few very modern properties that run 3 phase from the national grid. You can't take a single phase house and cable it up to use 3 separate phases. You could, but you would have to replace the single phase distribution unit with a 3 phase type, and have a whole load of switching to be able to switch between 3 phase from the inverters and single phase national grid power and route the single phase to the separate 3 phase feeds into the 3 phase distribution unit. It's getting silly. A far better approach is a single 23KW single phase inverter.
@@deang5622 This house was 3 phase, farms and some large properties have had 3 phase going back many years. But yes thankfully 3 phase is becoming more common on new builds that have heat pumps and EV charging due to expected loads.

Great video gents, and the reason Lee hasn’t had a hot pie at Greggs last couple of visits, is that they don’t keep them heated once baked due to the hot food tax. If they don’t keep them heated they don’t charge VAT. So it’s pot luck if you get a hot one that’s just been baked or not 🤣
We seriously have a hot food tax? If I’m being dumb and gullible I apologise but it sounds too British not to be true. We get taxed and licensed for everything so being taxed for hot food wouldn’t surprise me.
I guess we are lucky in Baltics/Nordic region where we actual sell our excess energy to the grid. Depending on the contract you sell at the fixed price or at stock price that changes every hour. We also use inverter that itself tracks how much energy panels are producing, how much you use yourself, buy from grid and also export to grid.
Was under the impression several victron energy inverter models support ESS so when paired with a number of compatible batteries could also be used as a house UPS

13:03 Why not use a ATS to switch power (PS: I have no idea how much they cost and how hard it is to implement, I just know they are used in Datacentres for keeping consistent power)
Personally when testing 3 phase circuits, I test R1+R2 on all phases because you want to check each end is continuous across each phase. Although you are proving only one phase you are assuming the other phases have been correctly manufactured. It’s unlikely to have a break but not impossible and have seen it happen. As artisans I expect you to do the same as you go the extra mile on everything. Not digging you out at all just how I do it and my view.
@@lewis94uk but you want to prove the conductors first before energising. skipping this is bad in my view, the whole point of the continuity test is to prove end to end of all conductors not just the earth....
@@anthonycampbell9807 Not required. You are required to do R1+R2 test, assuming there is a neutral present, and if you do that for all phases, then you *are* proving the continuity. And not only is it proving the continuity, it's measuring the resistance which determines the maximum current carry capability and so you are also verifying the current you expect the installation to be able to handle. If the R1+R2 tests results in very high resistance, such as caused by a cable break, then you investigate and resolve.
in theory it can, but you're not allowed to backfeed the grid. Of course, there are ways around it if you were designing a system from the start, but it looks they had solar before and now bolting battery storage to it.
Take the output from the inverter and feed an automatic transfer switch...power would then switch over automatically in the event of grid power. Easy.. Then there is no problem back feeding into the grid. But they don't have a huge amount of battery capacity to power the entire property for long.
Great video as allways. Quick question, what is with the board you british electricians allways put up, to mount your equipment on. I dont really see the point, whats wrong with installing straight on the brick wall? The install looks neat, but the board looks makes it look unfinished.
It's often called Concrete board or Cement board, it's meant to be a fire retardant type board. But as we all know, if these batteries do catch fire, the fixing board is the least of your worries!
Enjoyed the video. I heard somewhere, cant remember where, that you guys are doing a Myenergi Libbi battery install video soon. Keen to see that, when is it due out?
Jordan, you CAN NOT RUN CTs and data on the same cat 5 or cat 6 cable. IT WILL NOT WORK!!!!! Go and have a look at the Victron Energy charge inverters, they can be setup to switch to "Island" mode to supply power if the grid supply is lost. They can also be wired to a generator and programmed that is the batteries drop below a set level, the generator is started and will then run to recharge the batteries in the lack of solar.
I used to work at greggs I can tell you why no heat lamps , if greggs and other places kept food hot government have to put 20% on top of the prices same if you eat in government will charge 20% more
It is. But it is not exclusive to those situations. You can use it wherever you want, if the customer is willing to pay for it, and it is felt the level of risk warrants it. It might not be strictly necessary, but it's clearly being used in an "industrial" type room although in a residential property.
Great video, with the cost of energy going up these systems are making more sense. I didn't realise power wall was the only system that switched over to batteries automatically in the event of a power cut.
Here's a fantastic summary of that riveting video where we install the world's largest paperweight, I mean, home battery storage system. So, we've got this ginormous solar array, but 70% of the energy goes to waste - bummer, right? Well, fear not, we've got the solution! We'll slap a massive 23 kWh battery storage system into this house, so it can go almost off-grid. You'll be on the edge of your seat watching us lug around heavy equipment, struggle with mounting batteries, and complain about cold Greg's sandwiches. We take you through the riveting process of measuring, marking, and installing the battery storage system - step by step. You'll witness the birth of 23 kWh of battery storage, made up of six modules and a BMS (the brain of the operation). Don't forget the 10 kW inverter, because you need to convert that DC power to AC for your house, duh! We deal with pesky wall problems, making sure our battery babies are securely mounted, and install backup consumer units for those rare UK power cuts. And just when you think it can't get any more thrilling, we tackle cables and communications connections! So grab a cup of tea (or 23,287 of them, thanks to our excess solar energy) and enjoy this electrifying waste of time. Don't forget to like, subscribe, and question your life choices.
Interesting, we have two Tesla PWs with the third due imminently; with our solar panels we will not be taking any grid power at all from mid-March to October. We had a power cut last month but were unaware of it as we continued to automatically use the Tesla batteries, supplemented by solar power.
Why don’t you install a generator auto switchover unit We’ve been using for years in the field and they’ve never let us down to switch over a main power to inverted power
TBH, i'm not sure why they didnt get a larger battery pack and then just go off grid if they dont want to export. I've got the final 3 of 6 SOK 100ah 48v batteries arriving today.... Gonna take the house off grid with 7kw solar and a transfer switch.
Did I see this correctly? You're connecting the whole battery system AC-side? So the solar inverter first converts the DC from the panels to AC and then the battery converter converts it to DC again to store it? How much energy does that double conversion waste?
@@deang5622 To be fair, DC-DC conversion is hard, especially when it's for more than a couple milliamps. AC you can just run through a transformer, but those don't work for DC. I have to concur with Attila here, high-voltage DC (i.e. batteries in series) is a bit of a problem. On the other hand, panels are also connected in series, so one should be able to match panel voltage and battery voltage... :shrug:
@@HenryLoenwind You don't actually need DC DC conversion when charging batteries. All you do is ensure the solar panels are connected so you have a high enough voltage and then feed the current into a battery charger. So it is more than possible to charge up batteries without the losses associated with converting DC to AC and back again.
@@deang5622 That's what most of the hybrids do- they run a 48v or 72v battery bank, and use DC from the panels through their own (or external if required) solar controllers, and only have the one DC-AC conversion... The setup Jordan's installed tends to only be used (at least in Australia) where you already have an existing gridtie solar install and are wanting to 'retrofit' a battery backed hybrid system afterwards- it allows minimal modifications and reuses existing gridtie inverters and such- but at a loss of efficiency over one that is done pure DC from the start...
I wonder about these batteries. I'm using a set of car batteries for an old computer UPS which had dead sealed ones. They tend to die after a few years, requiring replacement. And they don't tend to see many heavy discharge cycles that would reduce their capacity. What kind of lifetime is there for these power walls? Do you need to replace the batteries every few years? What are the maintenance costs, now and projected as they become more commonplace? What happens with any dead batteries?
@@artisanelectrics So, assuming roughly a cycle a day, these batteries are rated for an average lifespan of 27 years? That's a lot better then I expected. By that time battery technology will have evolved. Not in the UK myself, but I'm going to have to look into that!
its great to see a large battery system but as this doesnt auto switch over - what does this power - dont get what the customer spent all this money on. is the heating permanently supplied by it? its not big enough to charge a car so, yes a bit confused
Why not, in this usecase because of the size of the solar array and battery storage, go for a semi-off grid system with an automatic failover switch? Seems like a waste when the power goes down and all you have are some extension leads...
what earthing system did you use for the island mode fuseboard that supplies the two double sockets? Sunsynk also offers island mode and is a great versatile inverter!
Because it isn't true???? It 'was' true- about a decade ago before high voltage MPPT took over from low voltage PWM solar controllers, but these days, light 100% overcast and showers will still see you up around 50% of normal output, and even heavy black overcast with heavy rain will be around 30% of normal
Not true that Tesla power wall is only system to provide whole house support, Victron ESS and even the dreaded SMA have systems. SMA is dreaded because after 10 years of installing I fell out with them due to being appallingly let down.
Massively expensive. Do a DIY install with pylontech batteries and a Solis Hybrid Inverter. You only need a local electrician for the new circuit. Don't get sucked in with these "green energy" electricians who inflate the costs just because its "green"
Great video!!! Hugely envious of that instal! That’s exactly what I want to build at mine. The point you made on switching to battery in the event of power failure. Is there really no way if doing that in the same way a UPS system works? I’ve no interest in a Tesla battery.
How hard could it be to install some high current contactors between the grid side and backup side to isolate the incoming tails, controlled by the grid side so it will switch the entire house to backup when the grid goes down.
Let them doing the first time experiment Jordan trying to do this experiment without any information because thinking how he will pay he’s employer’s at the end of the day
They don't have enough battery capacity to feed the whole house for long. 23kWh of battery is only 1 hour of use at maximum load for a residential house (with 100amp main fuse and 230 volts). In practise the house won't be operating at 23kW, but even if operating at 5kW, that's still only 4 hours of capacity from the batteries. It's not much if you're then having to wait for the next day of sunshine to recharge the batteries. In winter you might not get enough sun the next day. So this really isn't a design that is suitable for off grid use, save for a few hours at a time. And grid power in this country is extremely reliable, so why bother with the huge expense of designing a system and having enough capacity to run for 24 hours or more?
10kwh batteries cost £10,000. Then there is VAT and then installation pushing it up to 17,000+. I paid £750 for electricity last year (2 bedroomed tiny Terrace house). When I calculated how long it would take me to pay off that 17,000 and then adding on £5000 per ten years for the battery replacements I realised I would have died of old age before paying it off. Much cheaper for me to just run my washing machine and dishwasher at night when electricity is cheap. Cost me nothing and with time management on it's own I can cut my bills far more than if I invested in solar and battery packs. My advice to anyone out there thinking about solar and batteries is this: you can save money by simply using time management alone. Spend that money on insulation and double glazing instead. I installed timers on lights and on the cooker (hob) and heat the water at night when it is cheaper. Lights with movement sensors cut a huge amount of money off the bill. Turning off devices at the socket saves even more. Using your brain is the only way. Throwing money at something is not the way. It is in fact dumb.
Greggs don't Heat the food because they would have to charge tax on food which means the customer will pay more, that's what I was told at greggs anyways
I've installed this Inverter but Im having problems with the data from the monitoring, its saying im exporting more than the system is generating, and the gen meter doesent match the generation figure in the app, did you have any of these problems when you were commissioning the system?
Isn't a Tesla powerwall 5.8 kilowatt hours? I don't know if you can get Tesla powerwalls where you're at. I hope the ones that you're installing are really cheap

13:03 Why not use a ATS to switch power (PS: I have no idea how much they cost and how hard it is to implement, I just know they are used in Datacentres for keeping consistent power)
What about price per kwh?
An alternative power cut backup is an EV6/Nero EV/Ioniq 5.
Nice video. Could you go more into details on the process with the DNO and how long it took to get G99 processed.
Large export isn’t necessarily a problem. Octopus are paying 20-25p /kWh for export right now.
Personally when testing 3 phase circuits, I test R1+R2 on all phases because you want to check each end is continuous across each phase. Although you are proving only one phase you are assuming the other phases have been correctly manufactured. It’s unlikely to have a break but not impossible and have seen it happen. As artisans I expect you to do the same as you go the extra mile on everything. Not digging you out at all just how I do it and my view.
I can not believe that you would not test it, very strange comment from Jordan.
They might live test each phase
@@lewis94uk but you want to prove the conductors first before energising. skipping this is bad in my view, the whole point of the continuity test is to prove end to end of all conductors not just the earth....
18th edition requirement is to measure the earth - r1 +r2 only used to make it easier to measure the earth and also is a polarity check
@@anthonycampbell9807 Not required.
You are required to do R1+R2 test, assuming there is a neutral present, and if you do that for all phases, then you *are* proving the continuity.
And not only is it proving the continuity, it's measuring the resistance which determines the maximum current carry capability and so you are also verifying the current you expect the installation to be able to handle.
If the R1+R2 tests results in very high resistance, such as caused by a cable break, then you investigate and resolve.
Doesn’t the battery power kick in automatically in the event of a power cut?
If so, what is the reason for emergency sockets?
in theory it can, but you're not allowed to backfeed the grid. Of course, there are ways around it if you were designing a system from the start, but it looks they had solar before and now bolting battery storage to it.
Take the output from the inverter and feed an automatic transfer switch...power would then switch over automatically in the event of grid power. Easy.. Then there is no problem back feeding into the grid.
But they don't have a huge amount of battery capacity to power the entire property for long.
since when was Rob Beckett part of Artisan 🤣🤷♂
Great video as allways. Quick question, what is with the board you british electricians allways put up, to mount your equipment on. I dont really see the point, whats wrong with installing straight on the brick wall? The install looks neat, but the board looks makes it look unfinished.
It's often called Concrete board or Cement board, it's meant to be a fire retardant type board. But as we all know, if these batteries do catch fire, the fixing board is the least of your worries!
regarding the battery units leaning due to the weight: How does that fit in with the ventilation of the unit?
New Giant power bank sold in Alibaba for 135.000$ 250Kwh
Capacity to keep the property for 2-3 month or more
whats the gauge of that battery cable? seems too thin
Enjoyed the video. I heard somewhere, cant remember where, that you guys are doing a Myenergi Libbi battery install video soon. Keen to see that, when is it due out?
Jordan, you CAN NOT RUN CTs and data on the same cat 5 or cat 6 cable. IT WILL NOT WORK!!!!!
Go and have a look at the Victron Energy charge inverters, they can be setup to switch to "Island" mode to supply power if the grid supply is lost. They can also be wired to a generator and programmed that is the batteries drop below a set level, the generator is started and will then run to recharge the batteries in the lack of solar.
I used to work at greggs I can tell you why no heat lamps , if greggs and other places kept food hot government have to put 20% on top of the prices same if you eat in government will charge 20% more
I thought that swa was mainly used for mechanical protection in prone locations like external or workshop situations.
It is. But it is not exclusive to those situations.
You can use it wherever you want, if the customer is willing to pay for it, and it is felt the level of risk warrants it.
It might not be strictly necessary, but it's clearly being used in an "industrial" type room although in a residential property.
Loft space with vermin it’s a good choice, in the UK it means you don’t have to provide RCD protection to that circuit.
For 3 phase R1- R2 test just test between all 3 phases it’ll only take an extra minute
Great video, with the cost of energy going up these systems are making more sense. I didn't realise power wall was the only system that switched over to batteries automatically in the event of a power cut.
I only learned that recently too… seems crazy to me to not have that switching functionality built into these systems 🤷🏻♂️
Why can't a Automatic Transfer Switch be used ?
They don't really make sense though do they because the amount this entire setup costs by the time it breaks even you'd be 6 foot under.
@@TheRCBiker and Captain Killjoy has arrived😅
I have a Victron system that switches over automatically. There are others out there too which can have ATS component
Here's a fantastic summary of that riveting video where we install the world's largest paperweight, I mean, home battery storage system. So, we've got this ginormous solar array, but 70% of the energy goes to waste - bummer, right? Well, fear not, we've got the solution! We'll slap a massive 23 kWh battery storage system into this house, so it can go almost off-grid. You'll be on the edge of your seat watching us lug around heavy equipment, struggle with mounting batteries, and complain about cold Greg's sandwiches.
We take you through the riveting process of measuring, marking, and installing the battery storage system - step by step. You'll witness the birth of 23 kWh of battery storage, made up of six modules and a BMS (the brain of the operation). Don't forget the 10 kW inverter, because you need to convert that DC power to AC for your house, duh!
We deal with pesky wall problems, making sure our battery babies are securely mounted, and install backup consumer units for those rare UK power cuts. And just when you think it can't get any more thrilling, we tackle cables and communications connections!
So grab a cup of tea (or 23,287 of them, thanks to our excess solar energy) and enjoy this electrifying waste of time. Don't forget to like, subscribe, and question your life choices.
Great Video👍 Really Interesting.
A cool pie from Greggs is a result of not paying VAT to the government on pies. If you want a warm pie expect to pay more for it.
Interesting, we have two Tesla PWs with the third due imminently; with our solar panels we will not be taking any grid power at all from mid-March to October. We had a power cut last month but were unaware of it as we continued to automatically use the Tesla batteries, supplemented by solar power.
Thought it would notify you and shed circuits during a power cut? I know I can’t use things like my induction cooktop
@@edc1569 2PWs allow a 10kW draw, enough for an induction hob, but we would drastically cut power usage during a power cut.
Why don’t you install a generator auto switchover unit We’ve been using for years in the field and they’ve never let us down to switch over a main power to inverted power
Hi, how did you overcome the problem where the battery is vertically not level ?
TBH, i'm not sure why they didnt get a larger battery pack and then just go off grid if they dont want to export. I've got the final 3 of 6 SOK 100ah 48v batteries arriving today.... Gonna take the house off grid with 7kw solar and a transfer switch.
Did I see this correctly? You're connecting the whole battery system AC-side? So the solar inverter first converts the DC from the panels to AC and then the battery converter converts it to DC again to store it? How much energy does that double conversion waste?
About 20 percent. Only one of the disadvantages of high voltage battery systems.
It's crap isn't it? Solar panels output DC, no reason why that can't be used to charge the batteries directly with no conversions, except for DC-DC.
@@deang5622 To be fair, DC-DC conversion is hard, especially when it's for more than a couple milliamps. AC you can just run through a transformer, but those don't work for DC.
I have to concur with Attila here, high-voltage DC (i.e. batteries in series) is a bit of a problem. On the other hand, panels are also connected in series, so one should be able to match panel voltage and battery voltage... :shrug:
@@HenryLoenwind You don't actually need DC DC conversion when charging batteries.
All you do is ensure the solar panels are connected so you have a high enough voltage and then feed the current into a battery charger.
So it is more than possible to charge up batteries without the losses associated with converting DC to AC and back again.
@@deang5622 That's what most of the hybrids do- they run a 48v or 72v battery bank, and use DC from the panels through their own (or external if required) solar controllers, and only have the one DC-AC conversion... The setup Jordan's installed tends to only be used (at least in Australia) where you already have an existing gridtie solar install and are wanting to 'retrofit' a battery backed hybrid system afterwards- it allows minimal modifications and reuses existing gridtie inverters and such- but at a loss of efficiency over one that is done pure DC from the start...
Ahh Childs play. I have 128kW installed in my 4 bedroom house. Nice job though!
128kW or 128kWh ?
@@deang5622 My bad yes 128kWh. Just getting Lazy!
I wonder about these batteries. I'm using a set of car batteries for an old computer UPS which had dead sealed ones. They tend to die after a few years, requiring replacement. And they don't tend to see many heavy discharge cycles that would reduce their capacity.
What kind of lifetime is there for these power walls? Do you need to replace the batteries every few years? What are the maintenance costs, now and projected as they become more commonplace? What happens with any dead batteries?
Hey 👋🏻 Pure Drive rate this particular battery at 10,000 cycles at 90% DOD.
@@artisanelectrics Do you have one cycle per day? If so, that's 27 years.
My Powerwall is over 3 years old and it will probably out last me, and once it does die you can recycle over 90% of it.
@@artisanelectrics So, assuming roughly a cycle a day, these batteries are rated for an average lifespan of 27 years? That's a lot better then I expected. By that time battery technology will have evolved.
Not in the UK myself, but I'm going to have to look into that!
With a ups the very high C rate discharge tends to place a lot of wear onto the battery every time it kicks in.
Battery pack cant run the house so that install is just for the cars?
its great to see a large battery system but as this doesnt auto switch over - what does this power - dont get what the customer spent all this money on. is the heating permanently supplied by it? its not big enough to charge a car so, yes a bit confused
2:08 whats yout thought on electric boilers with system like that?
Why not, in this usecase because of the size of the solar array and battery storage, go for a semi-off grid system with an automatic failover switch? Seems like a waste when the power goes down and all you have are some extension leads...
Cool videos. Wish you guys worked in Sutton coldfield
I paid about $7000 for my DIY 25,700kwh system, with an 12kw inverter/charger.
what earthing system did you use for the island mode fuseboard that supplies the two double sockets?
Sunsynk also offers island mode and is a great versatile inverter!
How did you resolve the alignment issues of the stacked batteries ( top of one and bottom of the other ) ?
Most interesting. However, no one ever seems to mention that in overcast winter days solar generation can be almost zero .
Because it isn't true???? It 'was' true- about a decade ago before high voltage MPPT took over from low voltage PWM solar controllers, but these days, light 100% overcast and showers will still see you up around 50% of normal output, and even heavy black overcast with heavy rain will be around 30% of normal
Are you sure you used the correct gauge wire from the batteries for that 10kW inverter?
Mmmm.....
Looks like 100A is max on those cables
WOW
Mega..... How much?
Need Tesla Powerwall for automatic switch over? I'm not even involved in stuff butg solely from my youtube consumption I know this can't be true
Not true that Tesla power wall is only system to provide whole house support, Victron ESS and even the dreaded SMA have systems. SMA is dreaded because after 10 years of installing I fell out with them due to being appallingly let down.
Tesla is the only reliable one tbh
@@kobirelf97 PMSL- we got a comedian here lol
5:39 It’s a pretty premium treat, but this doesn’t come close to the good o‘l Pringles times 😇
What's the cost of these battery modules like compared to others on the market?
Massively expensive.
Do a DIY install with pylontech batteries and a Solis Hybrid Inverter.
You only need a local electrician for the new circuit.
Don't get sucked in with these "green energy" electricians who inflate the costs just because its "green"
Was looking at Pylontech batteries and have been quoted for a similar system but the brand was Fox which I've never heard of 😅
Great video!!! Hugely envious of that instal! That’s exactly what I want to build at mine. The point you made on switching to battery in the event of power failure. Is there really no way if doing that in the same way a UPS system works? I’ve no interest in a Tesla battery.
Install Goodwe inverters
How hard could it be to install some high current contactors between the grid side and backup side to isolate the incoming tails, controlled by the grid side so it will switch the entire house to backup when the grid goes down.
Let them doing the first time experiment Jordan trying to do this experiment without any information because thinking how he will pay he’s employer’s at the end of the day
That's how auto start generators do it, with an Automatic Transfer Switch. So I'm sure it would work for these.
Yeah owner of the building must need to buy a Auto Start Generator
Now
They don't have enough battery capacity to feed the whole house for long.
23kWh of battery is only 1 hour of use at maximum load for a residential house (with 100amp main fuse and 230 volts).
In practise the house won't be operating at 23kW, but even if operating at 5kW, that's still only 4 hours of capacity from the batteries. It's not much if you're then having to wait for the next day of sunshine to recharge the batteries. In winter you might not get enough sun the next day.
So this really isn't a design that is suitable for off grid use, save for a few hours at a time. And grid power in this country is extremely reliable, so why bother with the huge expense of designing a system and having enough capacity to run for 24 hours or more?
Did you fit an earth electrode for the EPS/UPS side of the installation.
Wrong victron also do a stand alone mode switch
I installed 30kwh. Home use
10kwh batteries cost £10,000. Then there is VAT and then installation pushing it up to 17,000+. I paid £750 for electricity last year (2 bedroomed tiny Terrace house). When I calculated how long it would take me to pay off that 17,000 and then adding on £5000 per ten years for the battery replacements I realised I would have died of old age before paying it off. Much cheaper for me to just run my washing machine and dishwasher at night when electricity is cheap. Cost me nothing and with time management on it's own I can cut my bills far more than if I invested in solar and battery packs. My advice to anyone out there thinking about solar and batteries is this: you can save money by simply using time management alone. Spend that money on insulation and double glazing instead. I installed timers on lights and on the cooker (hob) and heat the water at night when it is cheaper. Lights with movement sensors cut a huge amount of money off the bill. Turning off devices at the socket saves even more. Using your brain is the only way. Throwing money at something is not the way. It is in fact dumb.
This client obviously multi millionaire so money no object, I would expect they could pay their electric bill with ease anyway.
Massive
There's other systems that run back up power not only Tesla ..from what I'm reading online
Greggs don't Heat the food because they would have to charge tax on food which means the customer will pay more, that's what I was told at greggs anyways
I've installed this Inverter but Im having problems with the data from the monitoring, its saying im exporting more than the system is generating, and the gen meter doesent match the generation figure in the app, did you have any of these problems when you were commissioning the system?
Why not run a ATys P automatic transfer switch ?
Isn't a Tesla powerwall 5.8 kilowatt hours? I don't know if you can get Tesla powerwalls where you're at. I hope the ones that you're installing are really cheap
