Thank you so much lydia xxx

Thanks

Thanks very much :)

Glad you like it! Thank you :)

haha we will be there! :)

thanks for watching and commenting :)

thank you so much Lynda

Enviroguard we use

you are so welcome thanks for watching :)

Hi, you need to make sure your firmware is up to date - your installer can contact Fox, or you can do that yourself to request an update - the updates don't happen automatically unfortunately :)

Thank you and thanks for watching - to be honest I don't believe it is a regulation but some MCS assessors like to see it to help improve fire rating , and it does look better and is also good to fix to :)

If you have an EV yes, even more so! Solar still pays back though as it tops the batteries up and exports the excess, as long as the decent export rates are available it is worth it :)

He sure will, I have passed that onto him Conrad thank you very much :)

Thank you for the comment and watching! Yes it makes sense to hold back on the discharge during winter which is what I doo too.

@alpselectrical Any idea how I go about setting it up do I use my battery rather than export to the grid. I tried setting it up but it congress on once the battery is fully charged from the grid. It starts to discharge. Not sure how to set it to avoid that because it appears to override the time i set it up for.

Hi, thanks for watching. You don't always need a structural, it depends upon the roof type. If it is a regular dual pitch then most solar design systems will do the structural calculations for us, but you should receive the structural calculations for it in your proposal and paperwork to show the calculations have been done for both load and wind. If the standard dual pitch is a truss roof then we just input that into the system, however if it is a rafter style then we need to take dimensions of the span, rafter width, depth and spacing to input into the system. If nobody has even been in your loft you need to be asking questions for sure. If your roof is a flat roof, or mono pitch, or hip and valley like the one in this video then a structural survey is always required and must be carried out according to the MCS. The consequences of not doing so can be very bad. Most roofs are designed to hold the roof itself, not 2-300KG of solar panels also. If you came to us and said your roof was from the 1950's id be taking all precautions to ensure we were happy to install solar on it. Hope that helps.

@alpselectrical thank you so much for the reply. That is great to hear. My installer also told me that the system would tell them about this and also said they would know just by looking at the roof. Our roof is just a typical roof which is found everywhere. And, the loft conversion had been done before we bought the house, so hopefully all of OK?

Some do but usually bare minimum amount of panels to tick boxes, which is almost not worth having!

The PW3 does :)

Shocking isn't it! It all comes down to money. These builders want their houses wired for peanuts, which is why we would never work with a builder. But the electricians doing them need to make at least some money and so will spec the system the cheapest they can get away with. All new builds should be RCBO boards 100%!

@alpselectrical probably all installed by an unqualified person and then signed off by someone in an office. The worst I've seen is 100's of designs "signed off" on the last day of the grace and then being installed years later...

We went to a new build the other week just to carry out some minor electrical work and found crossed polarity at the C.U. Basically the main tails were the wrong way around in the main switch of the new board they had fitted (BG SPLIT LOAD)!!!! Needless to say they came back very quickly to sort it, but leaves you wondering what testing actually took place after installation?

@alpselectrical such a crazy, dangerous fault.

Hi, thanks for watching and commenting, in answer to your questions: 1. The customer has two cars which they charge at the same time. We moved and added his old charger into the system for free in the end actually as it was not much more effort or cost for us to do so. which they were over the moon with. 2. This is the PW2. The PW3 was not available at the time this job was at the pricing/DNO stage, and the customer wanted to move on with it as mentioned in the video, however more to the point, optimisers were essential on this job as mentioned in the video two panels on their own roof orientation would not be enough voltage for the inverter to kick in for most inverters, PW3 has a minimum of 60v which is too close to call for two panels on days where there is not much sun, therefore all panels needed to go on one string with optimisers to ensure they will work at all times. There is no better system than SolarEdge for optimisation and monitoring individual panels and this customer was very switched on and wanted the best. You cannot use SolarEdge optimisers with Tesla it has to be a SolarEdge inverter. 3. Answered this above. 4. It is not mandatory to use, I have never even heard of it and I have done all the Tesla training. They suggest using a dolly which is just common sense but I will stick with my £50 one which works perfectly well lol. Just to add there is a lot of hype about the PW3 at the moment with no chance yet to see if it stacks up. The fact it includes a built-in inverter could be a negative if the inverter side of things packs up, as that is either going to be a costly repair, or the entire unit is buggered. Only time will tell on this point. The PW2 is a proven model and allows you to spec with any inverter to suit the specifics of the system, and in this instance was the best choice for this job.

@@alpselectrical Thanks for replying. What you say makes perfect sense. Cheers

You are very welcome, thanks again for watching and commenting!

Not all builders provide solar as an option, including this builder on this site and so it was not an option for them anyway. Integrated panels may look nicer (in some people's opinions), but they are actually less efficient between 6-17%, due to the restricted/lack of crucial airflow allowed to cool them down, as trust me, solar panels get extremely hot under direct sun. Only time will tell if the integrated panels start to fail sooner than the on-roof panels due to this - it certainly makes sense that they would. On-roof panels can still look just as pleasant to the eye, but the majority of customers, are seeking maximum ROI over what they look like, as most people won't be staring at their roofs for prolonged periods. Right now, and this is extremely fresh news, the MCS is currently discussing the fire safety of integrated panels, which we received notification of last week, and we eagerly await the outcome. Clearly, it could have a significant impact on the industry going forward, but the regulations are changing constantly. It is hard to keep up sometimes. As you mention things that drop from the sky can gather in the recesses which isn't ideal. In my opinion having installed both, and with efficiency/ROI trumping appearance every time, the on-roof panels would be my recommendation.

@@alpselectrical I certainly saw a remark earlier this week on the efixx youtube channel about fire safety and in-roof solar. Apparently the consultant with concerns about this cited a very specific but unnamed panel brand as being a particular problem for in-roof solar. Certainly the GSE adaptors are sitting right on top of the wooden battens, so I can see the potential. I checked out the GSE website for the MCS certificates for their adaptor mounts. They certainly look legit. But sure, there's a risk, especially with loose connections under DC load. That reinforces the importance of the AFDD features, which SolarEdge has - although I haven't seen any tests of these devices.

Yes, we will await to see what comes of it, but things are changing very quickly. Thanks for the comment and for watching :)

Thank you very much! Some builders are installing panels to tick boxes but its the bare minimum to pass, in many cases just 4 panels which is pretty useless really.

Yes, thats the thing, most roofs are built to hold the roof itself, and tiles etc allowing for snow, not solar panels, and so consideration must be taken for these extra loads. Thanks for the comment and for watching, really appreciate it!

They can on my installer portal I have never looked at a customers web portal, only their app. I would assume that you can though, but the settings won't be available to you unless your system is on the latest firmware which you need to call Fox for to ask them to update them

@@alpselectrical can you please give me the number to call them?

If you go to the inverter details page on the web app, on the top left of the energy flow panel there should be a little icon (a box with a line coming out of the corner). Clicking this should take you to a page where you can edit it (I have mine set to user-defined, with manually added time periods)

It's a must - the serial number needs adding to the MCS certificate which you then need for the export payments. It is unnecessary as the smart meter at the origin does exactly the same thing but we just have to put them in

haha I will try to make sure I get plenty of sleep before your install! :)

Thats awesome buddy always good to make the system work as hard as possible for you! I charge my batteries every night regardless of the time of year. Take a look at my video about this on the channel. Funnily enough ASHP are on the menu for future but we are so incredibly busy right now I really am not sure when we will ever get around to it, at least not in the near future anyway! Thanks so much for watching and commenting :)

Hi there is the new FOX 2.0 app. The app recently underwent an update and so did have some issues but its as good as any other in my opinion, I have Fox at home too and use the app daily without a problem. Thanks for the comment btw!

@@alpselectrical thanks very much for responding, and the video, which gave me some faith in being able to get the most out of my soon to be installed system!

Bless you thanks for watching

Hi thanks so much its a pity we are not closer to you - where are you out of interest?? And thanks for watching!

Hi, whatever you set the min SOC is where the battery will stop and not drop below. I set mine to 10% too. Once it gets to min SOC it will just wait for top up either from grid or solar whichever is sooner :) Hope that helps

​@@alpselectrical My min SOC is set to 10% but it goes down to 6% overnight.

Hi such a good video,I havejust had a system installed, 6kw panels, 6kw hybrid inventory,plus 4 x 11kw Fox batteries, in this winter I intend to use my batteries to run my house completely on the batteries, which includes my 10kw Grant heat pump. I do charge my batteries in 02.00 to 05.00 low rate, but I was looking for the information on the app settings,mode scheduling etc. Thanks for all the information. Just what I needed. I have subscribed to you channel. As a point I have been talking to Octopus, about going on Cozy tarriff, as it gives me 3 slots to charge my batteries, totalling 8 hrs. The 2am to 5 am. Doesn't fully recharge them. Not a problem at the moment, I was worried how low can they go. I have been down to 40%. Before the charge kicks in. Thank you for an interesting explanation.

Thank you so much thats really kind and gives me motivation to keep going. A lot of work goes into these videos lol! Cheers for watching

Hi, yes, it is a bit fiddly isn't it?! Glad you go sorted though. Fox are always great at helping too over the phone

Thats amazing! So so glad I could help! Thanks for watching - don't forget to hit the subscribe button :)

You don't know how much that means to me! I put a lot of work into my videos and to hear people are enjoying them gives me the motivation to keep going with them :) Thank You!

Hey, thanks for watching and your comment! Yeah we can't wait to get our hands on a PW3 either! Ill be sure to do an install video on it! Regarding the 7.6kw max, I have never heard of that and cannot see why that would be a thing as the size of the array is only relevant to the inverter that it is connected to it. We have installed a PW2 with a 19KW solar array and two 6KW SolarEdge inverters. The only thing that would be affected by the size of the array is the speed at which the battery filled.
