We are with Eon.Next with an EV so 'Next Drive' is fixed for 12 months at 9.5p from 00:00 to 07:00, we charge EV as needed and Charge Solar Batteries to 100% during the 00:00 to 07:00, then with the 12 months 'Exclusive Export' we get 16.5p 24/7 so export all our Solar at 16.5p.
The slight issue is you wasted money on bifacial panels on a roof. They are meant for ground arrays and solar farms where the backside will work as intended. But no point changing them, or trying to paint the roof.
That’s incorrect, these panels were designed for roof use by Rea solar. Heatable has a little test of these on a roof with a standard panel of same wattage and showed a 20% uplift in generation
@@NicolasRaimo 20% increased pv output is groundbreaking!!!! If that was true, REA would advertise it everywhere and it would have been published in peer review journals and everywhere else. There is a reason for this, but certainly not what the installers claim. I have 19 panels with IQ7+ and everyone produces different amount. I have noticed shades that appear on certain panels only for a couple of days every year and once I was shocked to see one panel was almost black on the Enphase app. I was convinced that the microinverter failed, till the next day when I saw a plastic bag was stuck in one corner. Sorry pal
Yeah I’m not convinced on the bifacial. If this was really the case and not just carefully curated lies it should get published honestly. I would pay heatable to put a live demonstration for me in my house just to compare output side by side. If I don’t get that extra 20% I want my money back.
@@hellopsp180 these are not standard bi facial panels REA made loads of changes to them and how they work it’s uplift is in conjunction with the Enphase micro inverter they been designed to work with each other removing stuff from the panel to increase performance and start up… they preform better in low light 💡
Hi. We are on Eon Next. Import at 9.5 p/kwhr midnight to 7am. Export is at 16.5 p/kwhr. Our plan is also to charge overnight to 100% to export solar excess as long as we use less than the 9.5 kw that the battery stores at night which avoids battery charging the EV overnight. (Software set)
Slightly worse off than octopus intelligent but not much in it, assume you can't get intelligent as you can really benefit from extra hours I use it to RECHARGE the battery again.
@@NicolasRaimo But also no jiggery pokery with different charging periods, cars charging at unpredictable times, possible s/w issues with car or charger. I'm on Go with an EV, looking at going for solar and batteries and this seems on the face of it v interesting to me for its simplicity.
David a Q. If you set your car to charge in the off peak period does it come directly from the grid or go via the battery? And how do you control that?
@@Joe-lb8qn Hi. The car charger is set to allow charging on its software app (podpoint) from 12-7. It only actually charges when connected of course. I have set our Battery & Inverter to also charge every night from 12-7 in that software app (Givenergy). No further changes needed. Any excess in the summer from solar will be exported. Easy 👍
I have changed the way I think and use my solar/battery equipment, since I now get paid the same for export as import during the night on a simple economy 7 tariff. Hence no need to worry about over charging the battery at night in the winter, when the next day is really sunny, i just get paid more export at the same charge rate, once my battery hits 100%. Any solar diversion equipment is a waste of money, but thankfully ive not invested, even car charging is a simple process at night. So i agree the change in tariffs has made a significant difference in how I use and save energy costs
Using all your solar is nothing to do with greenwashing. It's obsolete legacy thinking from the time when exported PV was paid very little and less than the cost of off-peak import
For Octopus Intelligent Go customers, the export rate increased from 5p to 15p in September 2023 - this was the trigger for a change of approach for solar and battery use, and the elimination of the business case for solar divert products. Prior to that change, you were better off charging the car off diverted solar and not charging the battery overnight. Of course, rates could easily change again, so it's important to keep up and not stick to the same routine indefinitely.
How bi reflector works. The sun beams pass through the front of the panel and are absorbed as they pass through the back not bounce around between the roof and the panels.
Great video I live in Ireland and have a 5.1 kWh south facing solar and 27 kWh battery system and an ev . Three months ago I changed my provider for electricity getting night rate at 9 cent a kw for 4 hours day rate 39cent including vat and 24 kw cents for export. I set my battery to charge to 100% every night use electric heater for these hours and when needed charge my car at night rate . My bill for two months for1000kwh €124 including standard charge (€85) less standard charge if you use the system well it saves a huge amount of money
I'm similar. 7.7kwp E/W in Meath with 10kwh battery. Energia EV plan 8.15c between 2 and 6. 36.6c all other times. Charge to 100% every night and export anything else once batteries topped up. Eddi is just an expensive timer these days
This is probably a good idea in theory as it should be possible to exploit the difference between 7.5p and 15p/kWh for export if you have the right situation and equipment. However in my case the house battery is too small (only 9.6kWh) and my EV battery is also too small (only 28kWh). Today for example my EV is full so I couldn't start a charge to trigger an extension to the cheap period unless I go out for an unnecessary drive. There is very little solar in December here in NW England - only about enough most days to avoid using peak rate electricity after an overnight house battery charge. Today there was none!
I had real issues with the battery discharging when the Ohme charged the car. My inverter does not talk to my car charger. However, I have completely got round this by having three things: 1. 'Solar Assistant' running on a Pi which monitors and can change settings on the Inverter and battery and then creates its own API's that my next device works with. 2. Home Assistant running on a second Pi. This gives me the ability to charge the home batteries just the right amount of electricity to fill up between 11:30 and 5:30 at the lowest power rate over the 6 hours because it knows how much electricity is left in the battery at 11:30. It also stops the battery discharging when charging the car because of my third device. 3. 'Shelly EM'. This device is connected to a CT clamp that is purely checking my EV charger power cable for any power being drawn over 500 watts. If any is detected, my Home Assistant then tells my Solar Assistant to tell my Inverter to stop discharging the batteries immediately and purely draw from the grid. When the car stops charging, it tells the inverter to start drawing from the batteries again. After reading what I have written above, it sounds really complex but really it isn't, but it does require three separate network devices to work together. I could remove the Solar Assistant device if my Home Assistant had the inverter's APIs (and they are available) but I like the usability and simplicity of Solar Assistant which is a fantastic app/device and removes the need to go deep in Home Assistant which frankly I can't be bothered with as life too short. So what I have is a system that will charge my home batteries to full every night automatically and I can charge my car whenever I want and again, it automatically prevents any battery discharge for occurring. I don't have to micromanage a thing. Hint: I work from home and it is often a good idea during the day to start charging the car when you need to use the tumble dryer/washing machine/dish washer. That way you are using cheap electricity without needlessly discharging the battery or having to wait for later by using the overnight cheap rate. The only problem with this is it might stop charging the car after half an hour and you are then forced to use your home battery. For info I have the following hardware: Ohme Pro, LuxPower Inverter and PylonTech Batteries
Might be worth highlighting that this doesn't apply to households with the pre-2019 Feed In Tariff (FIT) contracts. With these, you get exactly the same payment whether you export all of it, or none of it; so its effectively free to use/store.
I’ve been thinking of doing the same as you. Can I confirm 2 things: when Octopus give you those extra peak time charging periods it’s the whole house that gets that rate and not just the car? Secondly, I presume you’re exporting the excess solar during the day?
Currently very little export due to very little generation but on sunny days yes! And when car is scheduled to charge the whole house gets it! See the video I tagged at end for intelligent
I have a similar solar and battery solution pending install. Why would you not dump almost all of your excess battery in the late evening and then recharge your battery to full during the off peak period. My typical usage would leave the battery at 70 - 80% around 9pm so I could dump all but 10% before 11:30pm and therefore make another profit on a further 7kwh per day. In my case with EON, I would make an additional £69.30 per month (6.9p import rate vs 40p export rate x 7kwh per day)
Next Export Premium Plus You'll receive 40p per kWh of electricity you export on a 12-month fixed-term export tariff. Available to : Customers whose electricity is supplied by E.ON Next and have had solar panels and a battery solution installed by E.ON Solar and Storage team from 1 January 2024.
@@NathanJones-cq1dz if your having to have panels by them that needs to be factored and compared against other solar quotes you might just be paying them the 40p in advance for them to give you back. It makes the maths more complex as of course your estimating what your generate and export
Just got Intelligent Go in the last month and have the problem with batteries discharging on out of cheap rate charge slots, I can’t move the CT clamp and the HA automation for this FoxESS system I have is a bit tricky to set up so I do the following. Always fully charge the house battery and set the complete by time and home charge time to 7:00 AM. There is not a lot of load on house in morning so even if you don’t get up to 7:00 as a charge slot it doesn’t matter too much. Don’t plug in until after 9:30 pm you don’t tend to get any slots before 11:30 pm and even if you do just un-plug and plug back in a bit later. Works for me at the moment but must sort out the HA FoxESS integration. P.S did you not do any Saving Sessions, don’t have the figures yet but think I’ve covered my electric cost for last month with the saving session credits, not bat for November and I'm still on export lite at 8p/kWh. Zappi was great diverting solar but if I can get the higher rate of export will just charge the car overnight
@@NicolasRaimo Yes I guess there would be something like that but the issue I have is to get control of the FoxESS system I need to make a local Modbus connection to inverter (you can't do it through the cloud interface) and I haven't managed to do that, hardware always more difficult than software so for now I'm just working around it
How much did your solar system produce in November? My 3.25 KWp system with solar optimisers is located in Central Scotland and the panels are split 60/40 east-west. It produced 99 units in October and 46 units in November, so your October figure suggests you are always going to be 40% better than me.
I have another solution which uses Octopus IO Go, my Ohme Home Pro charger and the Octopus R&D app which controls my Givenrgy inverter/battery/solar system. I have been observing the provision of extra time slots and find that-for my Prius Plug-in (9kW battery@ 2kWh rate)-a 4 hr window late afternoon/early evening here in the East Midlands, consecutive additional slots cover my car charging needs at the off-peak rate. I then use the R&D app to set a battery charge schedule for the same period in addition to the overnight schedule. Set and forget!
Which is fine if it doesn't allocate extra hours outside this or DOEST' allocate them etc... Home assistant should give set and forget but not currently with ohme, VIdeo about this coming up
@@NicolasRaimo I thought about that, so I played with my charger settings and settled on connecting the car at 4pm and stipulating the car to be ready by 19:30, giving just enough time to fill a depleted battery and sure enough, the charger set a schedule to charge continuously during that window. It has done that for a week now with no variation except if it predicts the battery cannot reach 100% by 19:30, it allocates more consecutive slots.
do you leave the battery on dynamic during the day? so it'll still stay topped up on solar and then export, and home will be using solar/battery? I guess you could set the battery to not use the solar at all and just serve the house - assuming your home usage is
I top up every night but allow solar to feed it during the day yes, this ensure I don't draw anything from the grid during peak times as on a a bad day the panels might not generate a lot but my home use could be high this kind of balances out my usages. On a bright day the battery usally stays on 100% all day, sadly there's no mode on my battery to favour full export all day
Painting of the glass at the rear of the panels ? I don't think is the best solution, I'm not sure that there would be enough distance between that surface and the cells for the reflection to be efficient as oppose to placing a reflective surface a few cm away. It would be worth testing but again I guess the manufacturer woul have done that before deciding to produce them clear
So panels are transparent as the light enters T intersections hits the roof and reflects on to the rear of the panels also containing cells. This has shown a marked improvement in efficiency already however I wonder if that would increase again if instead of my slates being black/grey they were white
@@NicolasRaimo Absolutely! That is I was implying, instead I thought you said "paint the back of my panels in white" 😀. . . perhaps you meant the surface behind such as the tiles etc... and yes it would. However the double sided PV modules can only offer a small percentage of improvement. Are your panels of the "half cell type" ?
Why install bifacial panels on a roof with a relatively low reflective albedo, instead of standard panels with an integrated white reflective backsheet? Bifacial makes a lot of sense for freestanding mounted panels, but otherwise???? Putting micro inverfters behind bifacial panels also seems odd. Aren't these typically black?
@redshift3 The installers claim that bifacial panels on a roof produce 20% more and they have a video about it which you can watch here ua-cam.com/video/mj6ZmIZP4hw/v-deo.htmlsi=XIixPxKQqd46Y6dQ
I cannot get intelligent as don’t have EV. I prefer agile and fixed outgoing at winter as I cannot control what happens once battery is charged and it exports at cheap agile rate. Also in sunnier months think flux would prove to be the better option. Most of the time they pay me each month build up a credit and use that towards winter months. Things may change next year as I switch from gas tracker to ASHP and might look at Cosy tariff at winter time.
With intelligent octopus go, do you get cheap rate all the time the car is plugged in or only when the car is physically charging? I have Ohme Pro which shows a charge plan so car is ready for 0730, but I’m not sure if I can still charge home battery to 0730 even if the car finishes charging early.
Are you really suggesting to people to move the CT clamp from seeing the full load of the property? If you are!!! Then WOW that’s some poor advice. The CT main purpose is ALM (Automated Load Management) moving it will no longer protect your main cut out fuse, incoming tails etc. Please do not follow this advice.
Yes John I am and its something many people will do, of course its SLIGHTLY dependent on if your CT was fitted for solar reasons or load management reasons, People for the later will know there situation when it was installed and its highly unlikely they'd of got approved for solar and battery without a fuse upgrade.
@@NicolasRaimo that is rubbish and you haven’t mentioned that in your video. The CT for the battery is managing the house load. The moment that person moves the CT to just see one consumer unit and not the other regardless of the fuse size puts that system at risk. It’s just very poor advice and should be removed. Otherwise if anyone has a serious problem with a system that could cause loss, injury or death I suggest they seek legal action against you.
@@jonjones8330 If you think a video on youtube is basis for a legal case you'd be wrong, Again if someones got SOLAR and BATTERY which is what this is talking about they are HIGHLY unlikely to of got DNO approval if there fuse was near limit
@@NicolasRaimo I think you need to get a lawyer or a better one if they told you you can’t be sued. People can be sued and a lawyer would advise not to give advice unless you’re a professional and have professional liability cover. Do you have all that Nick? For your sake I hope so. As you don’t know what the viewers system is they could have multiple consumer units (EV charger, House, Office, Workshop) the list can go on. So even with a 100amp fuse it’s still easy to negate the main function of that CT clamp to protect your system. Poor advice I either deep down you know it is. If not then you shouldn’t be doing these videos
I'm biased against bifacial panels due to their durability cos, as far as 2 years ago, we saw quite a few Trina 480W panels with the underside cracked after only a few months. Saying that, there's a video here on YT showing slightly better generation than standard panels. Otherwise, please follow my YT channel for solar panel focused videos.
Alas, I have a powerwall and even programmed with octopus intelligent and the 15p export rates, it still refuses to charge to 100% (only 60% yesterday as we had some rare sunny December weather, so it assumed a solar top up margin was in order 🤦🏻♂️). Furthermore, it DOES discharge the battery if the intelligent octopus schedules a charge. Tesla do not allow you to control your own battery and reckon their ‘learning’ algorithms are superior… they are not… in fact they are shite! This has been a source of frustration for me this last 2 winters with a 60% charged battery completely spent by 7pm on typical dull winter days, forcing me on to peak rate electricity use! I bought a 13.5kwh battery because thats what I needed and most of the time it is a sub 8kwh battery 🤦🏻♂️. Do you have any ideas as to how to resolve this (Tesla are not interested and don’t even acknowledge queries).
Try asking an electrician to rewire where you EV charger is on your supply and moving the Ct for Tesla Powerwall to be blind from EV charger, some people with home assistant have found some hacks to force the battery to charge by having it set the backup reserve to 100 at night and then during day setting export rate really high and import rate really low
Similar Powerwall experience since 2020 and experimented with different ways to make sure it did charge in the winter. Settled on setting the reserve to 35% which improved the “will it won’t it charge situation” a lot. After sunny days it expects there to be another sunny day, it’s a silly system. Just gone over to Intelligent from Go and had the battery being used to fill the EV. Luckily as it was the first time I had used Intelligent to charge the EV I was awake, saw what was happening and moved the reserve for back up to 80%. That filled the PW and also got the car to the required %. I now request the car be ready by 0400 and change the PW to 80% back up at 2330 as I’m usually still awake then. That has worked well but agree that the PW’s biggest fault is its algorithm that can’t cope with British weather.
@@lynnfisher4396 thanks for your input! I have tried tinkering with the back up, but it is a pain and relies on remembering to micro manage the whole situation, which is not ideal. The UK weather is impossible. I got 8kw of solar production on Saturday and only 272watts on Sunday, yet the powerwall only charged to 60% Saturday night and was at about 45% when I looked at 10am. Of course it ran out by 6pm 🤦🏻♂️. I find myself wishing I had got a Givenergy … would have saved a few £thousand too.
@@maverlk7 I agree it is frustrating and my installer who is really up on Powerwalls said his customers all say the same thing. It’s the only real criticism I have with it. It manages grid outages very well, the 5kw peak out put is really useful too. No other battery system available at the time of our install had both. The one thing I would say is try not to constantly move the back up percentage. I know in my previous post I said that’s what I do but now it’s “got used” to the 35% back up it works quite well for us. We found in our tinkering that it takes 2 or 3 days to settle down after a change. The odd change to 80% when charging the car doesn’t seem to upset it though. As you say the algorithm is its Achilles heel. Tomorrow is forecast to be very sunny here but Thursday is set to be a wash out and I fully expect the PW not to be at optimum charge on Thursday morning. We could try setting the back up reserve tomorrow night to higher than 35% but as we are low users we will be able to get through the day even if the battery is down to say 55% the following morning. We would have to reduce the back up to get to 2330 when it would recharge which is as you say more fiddling.
@@lynnfisher4396 I bought for the same reasons! The off grid (we are quite rural so seem to get a lot of power cuts) and 5k output were big factors. The switch over in a power cut is almost instant too! We both work from home and I have a house rammed with tech, so my average consumption is 15kw plus per day, which means on dull winter days, I really need the full 13.5kwh from the powerwall and 60% of that just causes unnecessary expense. The logic of ‘fill to full at 7.5p and if there is solar, export it at 15p’ seems to beyond the powerwalls diminutive AI. I know more control (with less off grid functionality) could be had with other systems like Givenergy though, so I think paying a premium for a less controllable and logical system is what galls the most.
If your on a FUSE limit to protect your install note that moving the CT could cause issues, If you are unsure check with an electrian first
We are with Eon.Next with an EV so 'Next Drive' is fixed for 12 months at 9.5p from 00:00 to 07:00, we charge EV as needed and Charge Solar Batteries to 100% during the 00:00 to 07:00, then with the 12 months 'Exclusive Export' we get 16.5p 24/7 so export all our Solar at 16.5p.

@@NathanJones-cq1dz if your having to have panels by them that needs to be factored and compared against other solar quotes you might just be paying them the 40p in advance for them to give you back. It makes the maths more complex as of course your estimating what your generate and export
Just got Intelligent Go in the last month and have the problem with batteries discharging on out of cheap rate charge slots, I can’t move the CT clamp and the HA automation for this FoxESS system I have is a bit tricky to set up so I do the following. Always fully charge the house battery and set the complete by time and home charge time to 7:00 AM. There is not a lot of load on house in morning so even if you don’t get up to 7:00 as a charge slot it doesn’t matter too much. Don’t plug in until after 9:30 pm you don’t tend to get any slots before 11:30 pm and even if you do just un-plug and plug back in a bit later. Works for me at the moment but must sort out the HA FoxESS integration. P.S did you not do any Saving Sessions, don’t have the figures yet but think I’ve covered my electric cost for last month with the saving session credits, not bat for November and I'm still on export lite at 8p/kWh. Zappi was great diverting solar but if I can get the higher rate of export will just charge the car overnight
In octopus api on Ha there’s a signal when intelligent cheap rate is use that to stop or start the charging of your battery integration
@@NicolasRaimo Yes I guess there would be something like that but the issue I have is to get control of the FoxESS system I need to make a local Modbus connection to inverter (you can't do it through the cloud interface) and I haven't managed to do that, hardware always more difficult than software so for now I'm just working around it
@@terrymackenzie6784 it read only? Complain to fox 🦊 customer feedback what they need
How much did your solar system produce in November?
My 3.25 KWp system with solar optimisers is located in Central Scotland and the panels are split 60/40 east-west. It produced 99 units in October and 46 units in November, so your October figure suggests you are always going to be 40% better than me.
I have another solution which uses Octopus IO Go, my Ohme Home Pro charger and the Octopus R&D app which controls my Givenrgy inverter/battery/solar system. I have been observing the provision of extra time slots and find that-for my Prius Plug-in (9kW battery@ 2kWh rate)-a 4 hr window late afternoon/early evening here in the East Midlands, consecutive additional slots cover my car charging needs at the off-peak rate. I then use the R&D app to set a battery charge schedule for the same period in addition to the overnight schedule. Set and forget!
Which is fine if it doesn't allocate extra hours outside this or DOEST' allocate them etc... Home assistant should give set and forget but not currently with ohme, VIdeo about this coming up
@@NicolasRaimo
I thought about that, so I played with my charger settings and settled on connecting the car at 4pm and stipulating the car to be ready by 19:30, giving just enough time to fill a depleted battery and sure enough, the charger set a schedule to charge continuously during that window. It has done that for a week now with no variation except if it predicts the battery cannot reach 100% by 19:30, it allocates more consecutive slots.
How do you get the Octopus R&D app please?
do you leave the battery on dynamic during the day? so it'll still stay topped up on solar and then export, and home will be using solar/battery? I guess you could set the battery to not use the solar at all and just serve the house - assuming your home usage is
I top up every night but allow solar to feed it during the day yes, this ensure I don't draw anything from the grid during peak times as on a a bad day the panels might not generate a lot but my home use could be high this kind of balances out my usages. On a bright day the battery usally stays on 100% all day, sadly there's no mode on my battery to favour full export all day
Painting of the glass at the rear of the panels ? I don't think is the best solution, I'm not sure that there would be enough distance between that surface and the cells for the reflection to be efficient as oppose to placing a reflective surface a few cm away. It would be worth testing but again I guess the manufacturer woul have done that before deciding to produce them clear
So panels are transparent as the light enters T intersections hits the roof and reflects on to the rear of the panels also containing cells. This has shown a marked improvement in efficiency already however I wonder if that would increase again if instead of my slates being black/grey they were white
@@NicolasRaimo Absolutely! That is I was implying, instead I thought you said "paint the back of my panels in white" 😀. . . perhaps you meant the surface behind such as the tiles etc... and yes it would. However the double sided PV modules can only offer a small percentage of improvement. Are your panels of the "half cell type" ?

Why install bifacial panels on a roof with a relatively low reflective albedo, instead of standard panels with an integrated white reflective backsheet? Bifacial makes a lot of sense for freestanding mounted panels, but otherwise???? Putting micro inverfters behind bifacial panels also seems odd. Aren't these typically black?
@redshift3
The installers claim that bifacial panels on a roof produce 20% more and they have a video about it which you can watch here
ua-cam.com/video/mj6ZmIZP4hw/v-deo.htmlsi=XIixPxKQqd46Y6dQ
20% uplift of generation on these panels compared to standard panels on the same roof, 20% is a HUGE increase!
@@NicolasRaimo it's incredible
@@redshift3
It’s impossible
@@serraios1989exactly. Incredible = unbelievable
I cannot get intelligent as don’t have EV. I prefer agile and fixed outgoing at winter as I cannot control what happens once battery is charged and it exports at cheap agile rate. Also in sunnier months think flux would prove to be the better option. Most of the time they pay me each month build up a credit and use that towards winter months. Things may change next year as I switch from gas tracker to ASHP and might look at Cosy tariff at winter time.
With intelligent octopus go, do you get cheap rate all the time the car is plugged in or only when the car is physically charging? I have Ohme Pro which shows a charge plan so car is ready for 0730, but I’m not sure if I can still charge home battery to 0730 even if the car finishes charging early.
If car is charging due to intelligent everything gets cheap rate
Are you really suggesting to people to move the CT clamp from seeing the full load of the property? If you are!!! Then WOW that’s some poor advice. The CT main purpose is ALM (Automated Load Management) moving it will no longer protect your main cut out fuse, incoming tails etc.
Please do not follow this advice.
Yes John I am and its something many people will do, of course its SLIGHTLY dependent on if your CT was fitted for solar reasons or load management reasons, People for the later will know there situation when it was installed and its highly unlikely they'd of got approved for solar and battery without a fuse upgrade.
@@NicolasRaimo that is rubbish and you haven’t mentioned that in your video. The CT for the battery is managing the house load. The moment that person moves the CT to just see one consumer unit and not the other regardless of the fuse size puts that system at risk. It’s just very poor advice and should be removed. Otherwise if anyone has a serious problem with a system that could cause loss, injury or death I suggest they seek legal action against you.
@@jonjones8330 If you think a video on youtube is basis for a legal case you'd be wrong, Again if someones got SOLAR and BATTERY which is what this is talking about they are HIGHLY unlikely to of got DNO approval if there fuse was near limit
I will add a note at top with your point however
@@NicolasRaimo I think you need to get a lawyer or a better one if they told you you can’t be sued. People can be sued and a lawyer would advise not to give advice unless you’re a professional and have professional liability cover. Do you have all that Nick? For your sake I hope so.
As you don’t know what the viewers system is they could have multiple consumer units (EV charger, House, Office, Workshop) the list can go on. So even with a 100amp fuse it’s still easy to negate the main function of that CT clamp to protect your system.
Poor advice I either deep down you know it is. If not then you shouldn’t be doing these videos
I'm biased against bifacial panels due to their durability cos, as far as 2 years ago, we saw quite a few Trina 480W panels with the underside cracked after only a few months. Saying that, there's a video here on YT showing slightly better generation than standard panels.
Otherwise, please follow my YT channel for solar panel focused videos.
Biggest question…
What’s going on with your hair??

Alas, I have a powerwall and even programmed with octopus intelligent and the 15p export rates, it still refuses to charge to 100% (only 60% yesterday as we had some rare sunny December weather, so it assumed a solar top up margin was in order 🤦🏻♂️).
Furthermore, it DOES discharge the battery if the intelligent octopus schedules a charge.
Tesla do not allow you to control your own battery and reckon their ‘learning’ algorithms are superior… they are not… in fact they are shite!
This has been a source of frustration for me this last 2 winters with a 60% charged battery completely spent by 7pm on typical dull winter days, forcing me on to peak rate electricity use!
I bought a 13.5kwh battery because thats what I needed and most of the time it is a sub 8kwh battery 🤦🏻♂️.
Do you have any ideas as to how to resolve this (Tesla are not interested and don’t even acknowledge queries).
Try asking an electrician to rewire where you EV charger is on your supply and moving the Ct for Tesla Powerwall to be blind from EV charger, some people with home assistant have found some hacks to force the battery to charge by having it set the backup reserve to 100 at night and then during day setting export rate really high and import rate really low
Similar Powerwall experience since 2020 and experimented with different ways to make sure it did charge in the winter. Settled on setting the reserve to 35% which improved the “will it won’t it charge situation” a lot. After sunny days it expects there to be another sunny day, it’s a silly system.
Just gone over to Intelligent from Go and had the battery being used to fill the EV. Luckily as it was the first time I had used Intelligent to charge the EV I was awake, saw what was happening and moved the reserve for back up to 80%. That filled the PW and also got the car to the required %.
I now request the car be ready by 0400 and change the PW to 80% back up at 2330 as I’m usually still awake then. That has worked well but agree that the PW’s biggest fault is its algorithm that can’t cope with British weather.
@@lynnfisher4396 thanks for your input! I have tried tinkering with the back up, but it is a pain and relies on remembering to micro manage the whole situation, which is not ideal.
The UK weather is impossible. I got 8kw of solar production on Saturday and only 272watts on Sunday, yet the powerwall only charged to 60% Saturday night and was at about 45% when I looked at 10am. Of course it ran out by 6pm 🤦🏻♂️.
I find myself wishing I had got a Givenergy … would have saved a few £thousand too.
@@maverlk7 I agree it is frustrating and my installer who is really up on Powerwalls said his customers all say the same thing. It’s the only real criticism I have with it. It manages grid outages very well, the 5kw peak out put is really useful too. No other battery system available at the time of our install had both.
The one thing I would say is try not to constantly move the back up percentage. I know in my previous post I said that’s what I do but now it’s “got used” to the 35% back up it works quite well for us. We found in our tinkering that it takes 2 or 3 days to settle down after a change. The odd change to 80% when charging the car doesn’t seem to upset it though. As you say the algorithm is its Achilles heel. Tomorrow is forecast to be very sunny here but Thursday is set to be a wash out and I fully expect the PW not to be at optimum charge on Thursday morning. We could try setting the back up reserve tomorrow night to higher than 35% but as we are low users we will be able to get through the day even if the battery is down to say 55% the following morning. We would have to reduce the back up to get to 2330 when it would recharge which is as you say more fiddling.
@@lynnfisher4396 I bought for the same reasons! The off grid (we are quite rural so seem to get a lot of power cuts) and 5k output were big factors. The switch over in a power cut is almost instant too!
We both work from home and I have a house rammed with tech, so my average consumption is 15kw plus per day, which means on dull winter days, I really need the full 13.5kwh from the powerwall and 60% of that just causes unnecessary expense.
The logic of ‘fill to full at 7.5p and if there is solar, export it at 15p’ seems to beyond the powerwalls diminutive AI.
I know more control (with less off grid functionality) could be had with other systems like Givenergy though, so I think paying a premium for a less controllable and logical system is what galls the most.
