Installing the new eddi under coat hooks! Brilliant so either the cupboard loses some of its primary purpose or someone hangs a nice warm coat over the unit and it’s vent holes potentially leading to overheating and premature failure at best!
Friendly advice as an electronics engineer. Always screw the antennas to the product before even powering it up, even if you are not planning to use the wireless functionality. This applies to all products that have antenna connections. Failing to do so, can permanently damage the wireless module inside the product...
@@hks-lion When you ommit to connect the antenna, all the RF power used to transmit the signal reflects back from the connector to the radio module, causing it to heat up and cook itself. Technically this happens due to the poor impedance match between the radio module and the (non existing) antenna. RF energy is a bit weird in that regard. If the path that you design it to travel has an impedance that is not accounted and/or designed for, bits of RF energy reflect from that point backwards and cause problems. In general, this phenomenon gets worse, by increasing the RF power output of the module. For example in handheld VHF/UHF radios, if you leave the antenna unconnected and push the transmit button, the RF module (which transmits usually around 5W of power) usually destroys the RF module in a fraction of a second...
Another consideration is that an exposed antenna connector is a great magnet for accidental human body contact, with associated ESD concerns. Screwing the antenna on immediately removes the threat of component damage, should the product have no (or insufficient) ESD protection on its RF ports.
As an electrician, I have an understanding of solar but not a full understanding to offer as a service. I see a lot of installs which don’t seek to reward the customers in a way which you guys would with your knowledge and expertise!
Just to say it’s a real pleasure watching your videos,im looking to get solar but it’s a real struggle at the moment,and with most companies I just get put on a waiting list,business must be booming at present,for solar installers,I will just have to wait for my turn
You say that device needs airflow from beneath and above but surely with those coat hooks above the device, the device is going to be covered with (possibly wet) coats etc.
@@piotrlobacz The easier option would be to move the coat hooks. Something the customer could do. Just wouldn't want the customer putting wet coats over it.
@@MJ720 easier operation would be is ro have installed it in more suitable palce. We all know what customers are like. He'll put of moving coat hanger and it will never end up moving or he'll be like. Oh it's nice and warm. It'll dry my wet coats nicely. 🤣
Having recently installed the Eddi as an amateur DIYer, this was one of the more reassuring Artisan videos in that it mimicked every stage of my install. Pleasant surprise that the Eddi came with an internal Hub, the faff with the WiFi, the failure to turn off the Eddi's own CT inputs and the discovery of a long lost screwdriver in the loft! But at 500 quid including the Harvi, seems an expensive bit of kit for a bit of basic monitoring. Surely the Solax inverter reads solar generation and house consumption/export?
With there being air vents on the Eddie, is it wise to instal it where coats etc could be hung over it, restricting air flow? *EDIT* I should have read all the comments, this has been highlighted a few times already
Always pop the Wi-Fi antenna on before powering up otherwise you can cause damage that is irreversible to the Wi-Fi module. Love your videos! Keep up the amazing work!
The Eddi is an excellent piece of kit. Our supplier just started charging in the region of 15p per kWh for gas, but they charge approx half that for electric during a certain period at night time. Needless to say our Eddi is now heating our hot water at night time, and the solar is doing the rest during the day time.
I suspect the problem you guys get with WPS connection not working may be because WPS is often disabled as it is insecure. I always make sure that it is disabled on my home system.
Great explanation on why you put in a whole new circuit - you always make it sound so simple! Also, nothing better than a homemade bacon sando to start the day off 👊
If you visit Derbyshire, you'll find that a bread roll is called a cob and some people will get quite aggressive if you call it anything else. Brown sauce on bacon.
Maybe the reason internet is always a problem if because you don’t understand the basic of networking and wifi! Trying wifi internet without connecting the aerials !o! Do you know what W stands for in Wifi?
Have you thought of a solution for a case where there is no hot water tank because of a combi boiler but they do have a hot tub that could be used to dump excess generation into but you'd have to let drop in temperature at times not used. [Probably a simple time clock on at midday for a couple of hours and, if a storage battery, in the middle of the night would be the simplest.]
With the Eddi, the solar CT will need changing to Generation, when set to Gen & Battery there is no data recorded and as you showed briefly at the end the local Solar generation is not shown on the Eddi., no idea why! Brown sauce for the win!
Great video, I have just installed the same unit. No Hub, not able to see the Reg Code in the control in the V hub, was you able to find the Reg Code??
I sometimes wonder with all these app controlled devices what happens if they stop supporting later (or earlier) versions of phone operating systems - I guess the trick is to make sure you select solutions that are very popular and wont go out of business or end support?
Hey Max, the customer asked for the eddi to be installed. Not sure if the previous installer had set up the WIFI functions on the Solax. However you are right you can get data from the Solax, but our customer wanted to receive the data from the eddi.
so surprised that the solax app doesn't give the exact information. I can vouch for fox as despite a few teething issues the latest app for android is very stable and gives very comprehensive information from solar pv and battery. Eddi is a nice product though but I cant help feel that your customer just paid twice.
When power gets sent back to the grid how do they get around the problem they can have in the USA videos I have seen of people back feeding generators and the risk that provides to linemen working further down the line during a power outage.....
You did this on a current solar installation but would it work for someone considering solar to inform ahead of an install. I am thinking a tailoring of the system can be achieved. Then factor in the future eg Heat Pump Electric boiler etc. would love to see a three phase system and your instal in a future vlog.
As an installer do you get to see more data than an owner? I can only see 2 months worth from the app but that is Zappi not eddi. Wouldn't want you to get to the end of the year and find out you don't have the data.
Eddi is the same, no difference whether on the App or website portal. You can go back to individual days prior to 2 months, but each operation is a faff as it is multiple clicks - who in their right mind wants to do that?! Maybe there is an API way to get historical data for comparison, but last I looked MyEnergi hadn't GA'd the API so it would probably be a best endeavours kind of thing. As you say, I'd hate to go back to that house after a year, 'So.... you have exported the grand total of...... errrrr..... hmmmmm.....'
Nice job except if they have a cloak room like ours when they put their coats back in they will block the air flow around the eddi. Our cloak room is full of Ladies Coats.
Great video Jordan. Really helps us up and coming sparks new to Solar PV. I never take anything into the loft that I don't want to lose! I would usually clip into the loft, and I hate it, but you've got to do it! I have always used a hammers length for clipping.
Mayo on bacon sarnies. Try it the salty creaminess combination is far better than a tomato (red) or vingear/molasses (brown) addition to a bacon butty.
I have just got the Eddi. Currently I have gas central heating heating the hot water for 1/2 hour each day. What I would like to do is on the days when I get cheap or free hot water from grid (octopus Agile) I’d like to automatically stop the gas hot water heater for that day only. Is that possible? I got the Eddi coming on when rate is 0p kWh right now, but gas water heater still kicks in on a Danfoss timer.
The antennas are not optional for RF circuits. Sure, modern modulation schemes mean the reception process is much more reliable but without the antennas, there's no impedance matched output to the RF amplifier, nor the input receiver circuit. Remember old TVs and the static on the screen when you didn't have a cable plugged in, same thing! What I kind of find amazing is the amount of electronics on that EDDI board for what should be a simple bit of logic and a relay output for the immersion. Looking at the PCB, I presume this is all on the AC side which is nuts but I guess the issue with working with what people already have installed.
It's not a relay output, Its a PWM mains output which is proportional to the spare available watt's from the solar. i.e. If only 100w is being exported, then the output will be switched on for 100/3000 of time and off for 2900/3000 of time for any given period in order to input 3kW into an immersion without clocking up the electricity boards meter.... the meter has a resolution of 3600 joules of energy, so as long as the 3kW load is switched on for less than the 3600 joules, no unit will be measured. The unit then has to measure how long the Solar PV takes to make up for the switch energy (
@@wino99999 3600 Joules is 1 Wh. Just because the meter display measures in Wh in no way means that you can import/export a Wh at a time over multiple cycles of the mains and the meter won’t notice - the import and export displays will notice that. You’re gonna have to PWM at well over 50Hz to make this work. Luckily doing PWM at higher than mains frequencies is trivial.
@@wino99999 Thanks for the explanation, really helpful, as soon as you mentioned PWM the board components made sense esp. with regards to suppression (EMC must be fun!). I suppose I was attempting to understand the way some of this kit works together and that, if the system was developed from scratch, wouldnt it be simpler to have a DC based system around the charge state of a battery. In short, I presume the unit is solving the problem where the solar output is converted into AC immediately and you have a system which sends energy back to the grid (therefore the configuration and logic to determine what todo is more complex). This is contrast to a much simpler DIY system Im thinking of installing based around a Victron Multiplus with LIfepo4 battery and no ability to feed back to the grid i.e. if the charge state of the battery is full AND load below a set amount AND water below a certain temperature, dump the excess into the water.
@@JasperJanssen The Electricity boards meter does not clock up any usage provided you use less than 3600J of energy, so what I was trying to explain was this is how these appliances work by turning on for a fraction of a second or cycle if it needs to, to prevent 1 Wh being recorded, then the equivalent amount needs to be exported to cancel out the use of less than 3600J fired into the immersion heater element before again doing the same ..... Otherwise turning on a 3kW load will always record against the meter if its say being switched by a relay!
@@robfodder5575 Yep completely ac based system, which is much harder to implement, especially if there's not a battery involved. Otherwise as you say if battery is charged to a healthy percentage and water is colder than needed..... turn on DC element, If battery level falls to below level even if water temp is not achieved.... turn off water heater!
Very informative video, it's too bad we live so far away from you guys. We had solar panels and battery storage installed recently, next step will probably be an electric car at some point next year. When we bought this house it came with an outdoor charging point on the driveway, which we were happy with. Now that I know a bit more about what products are and do, it turns out it is a Rolec EV charge point but it's basically an outdoor socket with it's own little circuit. I would definitely be interested in getting a MyEnergy Zappi when we do get an electric vehicle, any change you can do a video on one of them?
Is the Eddie PWM or proportional control? I had a catch power and the POS used to pulse full power and timed it based on your export (it was trying meter trickery)
Was told they could not run electric cables in the cavity walls from loft into attached garage and had to have trunking on the outside wall is that not the case then?
The Eddi isn’t set up correctly, it should show the power generated by solar as well as house consumption. You can also use the outputs to supply any resistive loads, like a heating element in a water cylinder. Rather then just giving this back to the grid you can install an outlet specifically to power an electric heater (resistive only) and any unused power would partially heat a room. It must be a resistive load as the eddi changes the voltage applied to the output to adjust the load available.
In my case I installed six clamps on the main panel, and an additional two for water heater tank and house heating circuit. It's allowed me to pick up on some concerning details, having separate monitoring like that.
You may want to try having a spare WiFi router/access point in your van, alongside with a long Ethernet cable. Thereby you can always relay customers WiFi to your construction site and update devices on the wall. You should just use the same SSID/Key (Name/Password) on this access point, as the customer does on his WiFi, which makes the devices connect to the original wifi, as soon as you switch of your temporary relay station 😉
No, it’s not. Live data can only be viewed by using the DSMR protocol on the P1 port or by using your own coils on the phases. Fluvius has no app, just a web interface. Which get updated over 4G every 24 hours. This to comply with GDPR.
@@syproful Als je Idd p1 poort gebruikt op de slimme meter kan je je verbruik uitlezen. Dit is toch wat ze hier uiteindelijk proberen. Of het nu per 24u word ge-update, je kan perfect je import en export nakijken.
none whatsoever if you consider the physics involved. the cable resistance is trivial over that short distance. whoever said that doesn't know that copper resistivity is low in the first place.
Eddi is not set up correctly. You should see the power from the solar system coming in to the house on the Eddi display, you have on got what is going out to the grid showing. Phone app is showing both.
I keep thinking about one of these to use some of the spare solar I gift to Octopus in the summer ! With the day rate being 5 x the night rate the ultimate sin is to import at the day rate so having fine control over loads as the sun comes in and out is the trick bot not sure if this can do that? For example I can vary the car charger to low / medium / high but that's not really variable enough. I suppose the easiest thing would be to add batteries but they are expensive. The ultimate solution is to force the Energy companies to invest in storage and pay consumers for spare solar thus connecting the private solar network - which is already connected of course !
It needs air flow to cool it and you put it underneath coat hangers that the customer is obviously going to hang stuff on ? Guess that there coats will be warm when they put them on and dry quick when they hang them back up 😉👍
Hi Guys I never have trouble connecting with WPS. It's more than likely the router hasn't enabled the wps. Try holding the wps button down for longer on the routers.
@@salibaba Another option is that the customer disabled WPS, possibly to prevent any unwanted connection attempts (the ability to support WPS is signalled by the router along with the SSID and other information).
It seams quite weird to me to install an Eddi to monitor an already smart Hybrid inverter wich additionally is able to separately monitor PV and battery power. If they connect something to the Eddi, it will always drain the battery first after the battery is full and it detects grid export.
Ive got an Eddi and Harvi to fit at somepoint, trouble is my boiler doesnt have a temperature thermostat (just a dial 1-6) so its going to be tricky to set up i think...
Wow... so: 1) You didn't know the Eddi hasn't needed a Hub since 8th August 2) Trying to pair the WiFi with the antennas still in the box 🙈 3) Internal CT not disabled 4) Installing the Eddi below a coat rack, when it is explicitly says "Ensure the device always has adequate ventilation; do not block the vents or obstruct the airflow at the back of the unit". So the unit won't be covered in thick jackets and coats then 🤷♂ Won't be booking you guys 😜
Not sure the point of an Eddie now as octopus pay you 15p for a kWh of electricity and you buy the gas at 11p so surely the gas would heat the water + 4p profit?
My Eddi equivalent cost me around £100 (Eddi's cost £450-500ish fitted) I use no Gas except for the hob (around .5 of a unit for 6-8 months of the year) dependant upon weather and temp. I estimate I save £10-14 every month over that period tailing off over the autumn/winter and increasing again over the spring. Based on last years figures it works out I saved around £122 (actually more because I have realised my Gas price in the s/s is still 3.212p/unit!) Now I plugged in the new Gas rates it's going to be circa £200 a year ) - based on 5.71p/kWh for my gas.
@@wino99999 if I only used gas for a hob I think I'd be tempted to go entirely electric and avoid the standing charge. (Obviously might entail installing a dedicated radial for the new hob but the savings would pay for that after a while).
@@wino99999 ah ok, fair enough. I'm actually wondering whether to go fully electric myself at some point, I think the time will come when the concept of a network of pipes supplying gas to individual domestic dwellings will be regarded as pretty antiquated. There was a video I saw on TH-cam that explained how heat pumps are so much more efficient than gas heating; personally I'd be keen to go that way myself, once the tech is more developed.
Bear in mind a lot of installers will be billing a lot for going up to location and on the roof, which can make installs with less panels feel like the price is bloated compared to bigger installs. I imagine more local installers will have a lower price for this. As a rough napkin calculation, give it one pound per watt peak for just the hardware, though there's a fair bit of variation.
That's a bacon barm, the issue here is mcs I've just fitted 4 x panels 1.62kw, a 1.5kw inverter right next to the consumer panel but I'm not entitled to any feed in tariff or any other mcs tech? Wiring all this up is easy to me but no-one will touch coz it was not installed via an mcs installer? Niciec can go f itself battery storage and screw these rules.

@@JasperJanssen The Electricity boards meter does not clock up any usage provided you use less than 3600J of energy, so what I was trying to explain was this is how these appliances work by turning on for a fraction of a second or cycle if it needs to, to prevent 1 Wh being recorded, then the equivalent amount needs to be exported to cancel out the use of less than 3600J fired into the immersion heater element before again doing the same ..... Otherwise turning on a 3kW load will always record against the meter if its say being switched by a relay!
@@robfodder5575 Yep completely ac based system, which is much harder to implement, especially if there's not a battery involved. Otherwise as you say if battery is charged to a healthy percentage and water is colder than needed..... turn on DC element, If battery level falls to below level even if water temp is not achieved.... turn off water heater!
Very informative video, it's too bad we live so far away from you guys. We had solar panels and battery storage installed recently, next step will probably be an electric car at some point next year. When we bought this house it came with an outdoor charging point on the driveway, which we were happy with. Now that I know a bit more about what products are and do, it turns out it is a Rolec EV charge point but it's basically an outdoor socket with it's own little circuit. I would definitely be interested in getting a MyEnergy Zappi when we do get an electric vehicle, any change you can do a video on one of them?
Does the current inverter and battery not have any data monitoring already?
Is the Eddie PWM or proportional control? I had a catch power and the POS used to pulse full power and timed it based on your export (it was trying meter trickery)
Was told they could not run electric cables in the cavity walls from loft into attached garage and had to have trunking on the outside wall is that not the case then?
I asked about adding panels to my existing system but was told that it would invalidate the MCS guarantee and I would lose my feed in tarrif deal.
You can add panels but as an additional system. You won't loose your Fit.
@@michaelmelwani7752 I only want 3 more panels adding (I have 12 now), would I need a seperate inverter/meter?
@@djmattc1978 yes, or if your inverter can take the extra power then your extra generation would be prorated against the original FIT
@@johnb7644 I’ve been told by the guys who issued the MCS that it’s not do-able so I’m stuck with that unfortunately.
@@djmattc1978
Do you mean the inverter is at it’s max or the extra panels being prorated
Didn't know that there were butt plants in England.
Cracking!
The Eddi isn’t set up correctly, it should show the power generated by solar as well as house consumption.
You can also use the outputs to supply any resistive loads, like a heating element in a water cylinder.
Rather then just giving this back to the grid you can install an outlet specifically to power an electric heater (resistive only) and any unused power would partially heat a room.
It must be a resistive load as the eddi changes the voltage applied to the output to adjust the load available.
I think monitoring the solar generation is optional.But as they installed it it should be showing
In my case I installed six clamps on the main panel, and an additional two for water heater tank and house heating circuit. It's allowed me to pick up on some concerning details, having separate monitoring like that.
What sort of concerns?
You got the electricians stapler yet ?
You may want to try having a spare WiFi router/access point in your van, alongside with a long Ethernet cable.
Thereby you can always relay customers WiFi to your construction site and update devices on the wall.
You should just use the same SSID/Key (Name/Password) on this access point, as the customer does on his WiFi, which makes the devices connect to the original wifi, as soon as you switch of your temporary relay station 😉
Shouldn’t the system have a shutdown procedure for the solar, rather than just knocking off the MCBs?
In Belgium it’s already build in the meter, so only need to download the app of the supplier and you see import and export.
No, it’s not. Live data can only be viewed by using the DSMR protocol on the P1 port or by using your own coils on the phases. Fluvius has no app, just a web interface. Which get updated over 4G every 24 hours. This to comply with GDPR.
@@syproful Als je Idd p1 poort gebruikt op de slimme meter kan je je verbruik uitlezen. Dit is toch wat ze hier uiteindelijk proberen. Of het nu per 24u word ge-update, je kan perfect je import en export nakijken.
Could eco7 be a clue for economy 7 tarif.
Excellent video…✌🏽👏🏽✌🏽
Glad you enjoyed it
What impact does shortening the CT clamp cables have? Have seen some that advise against doing so but without any explanation.
none whatsoever if you consider the physics involved. the cable resistance is trivial over that short distance. whoever said that doesn't know that copper resistivity is low in the first place.
I always have brown sauce on bacon/sausage. I used to buy HP but I switched to Daddies because it's half the price and I can't taste the difference.
It's the sea journey from Holland that makes the HP less tasty......& the price.
Eddi is not set up correctly. You should see the power from the solar system coming in to the house on the Eddi display, you have on got what is going out to the grid showing. Phone app is showing both.
I keep thinking about one of these to use some of the spare solar I gift to Octopus in the summer !
With the day rate being 5 x the night rate the ultimate sin is to import at the day rate so having fine control over loads as the sun comes in and out is the trick bot not sure if this can do that?
For example I can vary the car charger to low / medium / high but that's not really variable enough.
I suppose the easiest thing would be to add batteries but they are expensive.
The ultimate solution is to force the Energy companies to invest in storage and pay consumers for spare solar thus connecting the private solar network - which is already connected of course !
HP, Chef, or YR; Brown sauce all the way!
I’m hoping to add an Eddi to my solar and battery storage. I’ve got a Zappi, hub and harvi already. Does that replace the hub as well then?
You can add the Eddi without enabling the hub built into the Eddi.
It needs air flow to cool it and you put it underneath coat hangers that the customer is obviously going to hang stuff on ? Guess that there coats will be warm when they put them on and dry quick when they hang them back up 😉👍
Yes, brown sauce on bacon; ketchup on sausages.
Hi Guys
I never have trouble connecting with WPS. It's more than likely the router hasn't enabled the wps. Try holding the wps button down for longer on the routers.
Yep, my old one you had to hold it till it flashed (Virgin) but my new one is a single press. Seems to vary between manufacturer.
@@salibaba Another option is that the customer disabled WPS, possibly to prevent any unwanted connection attempts (the ability to support WPS is signalled by the router along with the SSID and other information).
It seams quite weird to me to install an Eddi to monitor an already smart Hybrid inverter wich additionally is able to separately monitor PV and battery power.
If they connect something to the Eddi, it will always drain the battery first after the battery is full and it detects grid export.
Ive got an Eddi and Harvi to fit at somepoint, trouble is my boiler doesnt have a temperature thermostat (just a dial 1-6) so its going to be tricky to set up i think...
Normally (in my limited experience) an immersion heater will have its own thermostat.
take a look at the honeywell s system wiring. you should be able to add a cylinder thermostat quite easily or get a qualified person to do it for you.
Pmsl "woken up at the crack of dawn" as you walk out stretching 🤣
Brown sauce especially hammonds chop brown sauce finest from Yorkshire on bacon or sausage or anything fried breakfast wise
Brown sauce all the way!!! Definitely a cob though not a roll 😂
Agreed. Always brown sauce with bacon.
00:00 😂😂😂😂 Thank you, that was such a Cory joke 😂😂😂😂
Why does this thing get so hot? Surely you want that heat going into the water, not the air. Doesn't sound very efficient.
Heinz Red sauce on a good sausage roll, M&S brown sauce on a bacon sarnie and Cornish pasty.
Hi, you cant do like that, connect device without antennas, you can ''burn'' it...
Fresh roll, real butter, thickly sliced bacon , needs nothing else.
I want that bush. I didn't think I would say that on TH-cam. 😂
You only have Brown Sauce if you have an Egg, ie Bacon & Egg, Saus & Egg etc ANY other time its Ketchup!
Wow... so:
1) You didn't know the Eddi hasn't needed a Hub since 8th August
2) Trying to pair the WiFi with the antennas still in the box 🙈
3) Internal CT not disabled
4) Installing the Eddi below a coat rack, when it is explicitly says "Ensure the device always has adequate ventilation; do not block the vents or obstruct the airflow at the back of the unit". So the unit won't be covered in thick jackets and coats then 🤷♂
Won't be booking you guys 😜
The coat hanger was removed afterwards 😤
The perfect roll has to be sausage, hashbrown and hp brown sauce.
You can use 1.5mm flexi cable for that no need truncking wasting time
I would prefer to call it "Broodje spek met ketchup" I guess?! Looks 'lekker' :)
Not sure the point of an Eddie now as octopus pay you 15p for a kWh of electricity and you buy the gas at 11p so surely the gas would heat the water + 4p profit?
I like that you had some bacon with you tomato sauce roll.
I prefer my bacon roll without sauce, I.e. as God intended;-) to misquote blackadder
The payback for one of these is many years even supposing it lasts that long. Longer still if you have a Go type tariff.
My Eddi equivalent cost me around £100 (Eddi's cost £450-500ish fitted) I use no Gas except for the hob (around .5 of a unit for 6-8 months of the year) dependant upon weather and temp. I estimate I save £10-14 every month over that period tailing off over the autumn/winter and increasing again over the spring. Based on last years figures it works out I saved around £122 (actually more because I have realised my Gas price in the s/s is still 3.212p/unit!) Now I plugged in the new Gas rates it's going to be circa £200 a year ) - based on 5.71p/kWh for my gas.
@@wino99999 if I only used gas for a hob I think I'd be tempted to go entirely electric and avoid the standing charge. (Obviously might entail installing a dedicated radial for the new hob but the savings would pay for that after a while).
@@wino99999 What is the equivalent?
@@grayhalf1854 I have a gas boiler for heating which is still not yet turned on.
@@wino99999 ah ok, fair enough. I'm actually wondering whether to go fully electric myself at some point, I think the time will come when the concept of a network of pipes supplying gas to individual domestic dwellings will be regarded as pretty antiquated. There was a video I saw on TH-cam that explained how heat pumps are so much more efficient than gas heating; personally I'd be keen to go that way myself, once the tech is more developed.
Prefer the cheap own-brand brown sauces to HP.
I used to buy HP but I switched to Daddies because it's half the price and I can't taste the difference.
Can someone tell me the estimated price from a solar system say £10k to 20k
My 4kw array and 5kw battery cost 8.5k a few month ago, Id say youd be looking at 10-12k for a similar system right now
Bear in mind a lot of installers will be billing a lot for going up to location and on the roof, which can make installs with less panels feel like the price is bloated compared to bigger installs. I imagine more local installers will have a lower price for this. As a rough napkin calculation, give it one pound per watt peak for just the hardware, though there's a fair bit of variation.
about 12k for 5kW with battery at todays prices installed
Ketchup on a bacon sandwich? Mayo for me, please. With a slice of tomato.
Gosh, you're well posh.
La-di-da!
Always HP Sauce on a bacon roll
I used to buy HP but I switched to Daddies because it's half the price and I can't taste the difference.
That's a bacon barm, the issue here is mcs I've just fitted 4 x panels 1.62kw, a 1.5kw inverter right next to the consumer panel but I'm not entitled to any feed in tariff or any other mcs tech? Wiring all this up is easy to me but no-one will touch coz it was not installed via an mcs installer? Niciec can go f itself battery storage and screw these rules.
Ketchup on a bacon roll is just sacrilege.
Bacon Rolls: Branston Pickle.
If the Eddie needs air flow above and below... why are you putting it under a overlapping coat rack? 🤦🏻♂️🤣
Definitely brown sauce with bacon and fish finger sandwiches 👍
