Nice job as always. However, homes and garages are starting to look like industrial substations and boiler rooms which adds complications when things fail. 20yrs+ ago we all ripped out all water tanks in lofts and bathrooms to fit simple combi boilers removing loads of pipework too. Now we go back to it all. 🙈

Hi Nick- we need these over at Harvest Green Development/ Fuzed Electrical - I regret throwing away all the ends from the commercial inverters would’ve have 10’s of thousands by now!

[@FiddlingwithmyWhistle]

Great video, but... when are you taking on new work ?

[@utterlyexiged]

It will be interesting to watch the evolution of solar over the next decade, as most the the equipment installed here will more than likely be bulky or redundant. Solar roof tiles may even be the norm.

[@Lewis_Standing]

Fixed on rails can produce more than integrated or solar roof tiles because in summer they will stay cooler because of airflow Uglier but better in the increasingly hot summers

[@jcoakley4627]

Fantastic video, your getting better by the month. Just checking did you put all the panels on one string 🤔. JC

Great video , I’m new to the PV and starting to venture toward this ,can I ask the swa used for dc double insulated between cores and not normal ac swa or are you allowed to use ac swa ? And is the surge for dc specific for dc ? you guys do great installs keep up good work lads 👌

[@liamg5632]

Great video! Are you able to put all the kit in the loft? Just starting to look at systems but don't have a garage. Thanks

[@ForTheBirbs]

Hi from Sydney, Australia. Thanks for your interesting videos on solar installation in the UK. I assume using DC string with optimiser gives more options for battery installation and avoiding multi DC/AC/DC conversion losses? Can the optimisers be signaled to shut down in case of fire? There have been quite a few fires here on rooftops (dodgy product or installs) and the inability to isolate the panels at rooftop has been an issue for firefighters. I'd be interested in the DC surge setup. Cheers

[@kevharrigan2341]

Great video. Can I ask how many strings made up the 20 panels and if they were connected in series/parallel please? Thanks

[@RichardABW]

Great video, a few questions... Do you ever wall-mount the battery as I believe is standard or don't you like this because of the weight? Did you apply for 8kW, and if so what was needed/what was the reason that they only allowed 5kW?

[@parmjitdhugga3536]

It would be great to hear more about the performance of solar batteries during the winter months. I assume their performance drops just as it does with an EV battery because I believe batteries perform best around 20degrees C. Would it help to keep the battery warm if garage temp drops to 2 or 3 deg C? How much drop in battery performance do people experience?

[@andyhodchild8]

Interesting that you let the armour float, I get the fact that modules are current limiting devices but I don't like anything floating. If the inverter has earth fault monitoring, which I think a lot do have, then it would alert you to a potential issue? I am currently wrestling with have two or even 3 earth systems which I don't really like. Can't export pme to ground mount, but need to earth DC SPD's back in garage and 4 x 50m swa strings, pme dno earth and earthing pme to ground rod for ESS earth in backup if pme is lost. Hopefully earth systems will not have much if any potential differences where they are close. Hope documentation will be read!

[@gino2465]

Oval R ,great video. I have noticed a lot of installs that are now sunk into the roof , this must be more costly than just using the standard rails . Why do they do this is it a planning issue. Disturbing the whole roof. Also less air flow .

[@1701_FyldeFlyer]

It looks neater, customer specified it or planning issues due to the property age \ location. Personally, I dont like the idea of taking off most of a perfectly good roof even if it does look better.

[@MichaelPickles]

I wonder if it's worth putting some lock tight on the thread of the roof rails? 25 years is a long time

[@MrLegend139]

Great video love watching them. I have a question, can the DC cables be ran through an internal wall? Mine are currently clipped down the side of my house externally through the garage roof into the garage where my inverter and battery are, but we plan on knocking the garage down and putting a bedroom and integrated garage in place of the existing garage. Thanks

[@buckshee]

It’s not advisable to do so but if you do then they must be mechanically protected.

[@philburt52]

Nice to see a professional install, can't help but wonder what the payback is given the battery is like to need replacing in 10-12 years.

[@robchurches598]

Great video and work as always. But couldn’t the 8kW inver be installed at this stage due to the size of the PV array and limit the export (G100) to the grid to comply with the requirements of the DNO?

[@craigbutler6243]

No, because the inverter they want to fit in the future isn't sold yet as its the new solar edge back up type that will provide during a power cut.

[@gino2465]

Question did the DNO accept this system as it's over 3.86 KW in single phase.

[@anthonychiu5136]

From one sparks to another. How did you terminate the swa cable coming down to the dc cables going into the inverter ? I did not actually know you could run swa cables and join onto dc in loft ? nice work btw.

[@simoncoley2094]

You said New regulations need a DC Isolator and a DC surge protection device. when were these regulations changed? I have just had Solar panels, Powerwall and a Solar edge inverter fitted last week. The installer said I didn't need them as there was a DC isolator in the Solar edge inverter. A bit confused about whether I need them or not. Can you clarify it for me. Thanks

[@normanpouch]

Is surge protection required for domestic solar please.

[@d.b.cooper1]

Have you ever heard of a junction box making box or general humming/sounds from the loft few months post a solar installation? Really annoying humming sound which gets worse post sunset & doesn't seem to be via invertor, any random thoughts on what it could do? Thanks

[@Finance-Food-and-Freetime]

Are solar with micro -inverters running to an AC battery not the best option? I’ve just installed solaredge system with their 5kw inverter to their battery and can’t think of how it’s better

[@jonowilson62]

Sam have a question, running two strings from roof into loft, I see you go into junction box and then use two core 4mm swa down to isolators. Could we use 4 core 4mm swa for the two string instead of doing two runs to the inverter?

[@Llamberg.Railway]

A company I would employ for my proposed solar install, but unfortunately they are not taking new enquiries. I have asked 3 times now but no further response even when promised. I have now given up further enquiries and probably won’t install solar 😔

Hi mate , just bit confused. You got 8KW system on 5KW inverter with single string ?

[@RichardABW]

Hello again. Sorry if I missed this, but I'm assuming that this is a single string design? Also, could you share what brand your clear-lidded boxes are please?

[@MichaelPickles]

Nice and neat! Did you use ferals on the DC cables? I find multistrand cables cannot get a good bite when being clamped down without a feral. I did not know you could run DC down solid SWA cable. I thought it preferred multistrand. being over that distance. Maybe 6 mm would be better.

[@rajk5307]

Im wondering the same. I would have thought tinning multistrand cable is better than a ferrule. Not even sure what those ferrules are made from. And running DC down a two core cable? Again don’t know the answer but wondering if there would be some induction losses. Although it looks neat.

Why have you installed a DC isolator when Solar Edge specifically recommend you do not use one?

[@mickd802]

Those brackets holding the rails seem to be raising the tiles so they do not seat correctly, I’m not sure I’d be happy with that in a windy area, is there another option?

[@buckshee]

The notches on the back of the tiles should really be ground down to prevent this. I rarely see this happening mind.

[@OvalRenewables]

Thanks for the concern, all the tiles have been ground down to allow the hooks to pass under the tiles without them lifting, they may still lift ever so slightly but this will be extremely minimal.

[@14fy]

What's your view on tigo optimizers which work with any inverter just done a system using them and givenergy inverter and battery really nice and simple.

[@Lewis_Standing]

Will he be able to sell that inverter as nearly new? Or is this not allowed? Will you use it as a good available working part on your next 5kw system? At a discount for the customer? Good sustainable thing to do to reduce e waste

[@OvalRenewables]

This was something we discussed with the customer. He will be able to sell it on as long as it is sold as a second hand inverter. However they have a 12 year standard warranty so will be able to stand the test of time 👍

[@malachygallagher4936]

Hi Have you one or two strings feeding inverter? Looks like you only have one😢! Will that not overload inverter? Regards mg.

[@OvalRenewables]

Hi there, thanks for the comment as this system is SolarEdge . It is able to handle more panels on a string than a standard string inverter. Therefore, most domestic SolarEdge installations are only one or two string systems

[@Dontmindme__]

Hi guys, hope you respond to this as it’s bugging me and I’ll never get an answer! This is set up as one string but at the inverter it looks like you have two strings installed with the MC4 connectors? Am I missing something?

[@OvalRenewables]

Hi there, yes this is correct there is one string coming from the roof and then the SolarEdge battery connects into the inverter like an additional solar string would do. This means the SolarEdge battery can charge with DC direct from the solar. 👍

[@oliver90owner]

Is there any reason why the DC, from the panels, can not be taken inside the roof and enphase micro-inverters placed inside the roof?

[@OvalRenewables]

The SolarEdge system doesn’t use micro inverters like enphase. We are unable to extend the cables between the panels and the optimisers. We can install the optimisers in the loft when it’s an in roof system as the panel cables are long enough. To reach through the felt to the optimiser. 👍

[@oliver90owner]

@@OvalRenewables Enphase input is DC and output is AC. I was asking about micro-inverters, not DC to DC adjusters. But thanks for the reply.

Hi I’m in the process of solar this is (18) x 400-420watt jinko tiger neo all black panels this produces 7.56kw of solar power ,coupled with (18) emphase microinverter ,this will be connected to alpha smile b3 plus 3kw ac coupled solution with 5.04kwh modular also adding another 5.04 battery , this would be 10.08 kWh total ,my only concern is is the inverter only able to supply 3kw ac maximum,as the panels altogether can produce 7.56kw of solar power ,info would be appreciated 👍

[@guffermeister]

anything over 3.6kw needs DNO permission to feed back into the grid. This isn't always guaranteed to be accepted and some installers won't do it as it can take up to 3 months for an answer. If you have a battery then you'll need to keep that charged and therefore you wouldn't necessarily be expecting to export more than 3kw back anyway would be the theory I'd be working with

[@gingerninja7187]

@@guffermeister Hi thanks for your information, what’s up with solar companies not wanting to do the paperwork ,it just seems a waste to being able to generate 7.56kw of solar power, my quote was for 2 5kw batteries, but with the maximum usage of 3kw inverter, I’ve decided not to use the company

[@guffermeister]

Because it's not guaranteed that the DNO will say yes and many don't want to have a customer hanging around for weeks. Proving you don't need more than 3KW then that size inverter is fine as you'll be dumping the rest in the batteries. The installer may already know there are issues in the area you are and you may be stuck at 3KW anyway....

[@jonathan.h]

What screws (type & size) do you use for fitting everything to the 12mm hardi backer?

[@paulf3353]

jeez It takes some much space, so many unnecessary components. PV isolator is built in in solaredge (and you also have a junction box in loft you could just put isolator there. If you need to replace inverter, just do it when it is dark and put caps on MC4. Same for over voltage on DC, solaredge already has it built it. But why there is no trunking for PV cable on wooden loft?

@@buckshee thanks for explaining your concerns. I totally understand why you may fear micro cracks. However if you were to try it I believe you would see that it puts no pressure down into the silicone. The pressure is actually on the aluminium frame as the panel is lifted by the glass sheet.

SolarEdge equipment is highly unreliable. I own an electrical company that specializes in solar and we have replaced almost every HD wave SolarEdge inverter we have ever installed. The fact that he is a fanboy of SolarEdge shows me he hasn’t worked in this sector for long.

[@OvalRenewables]

Thanks for the comment, saddens me that you feel the need to post a negative comment about our experience when you have a genuine point to raise about reliability of the equipment. We have been in the industry for just over 10 years. Whilst we have replaced some solaredge equipment it is very little compared to the number we have installed. I feel the reliability has increased massively over the past 5 years.

[@Dontmindme__]

As soon as someone posts a nasty comment in their argument it invalidates their point and makes it quite obvious they’re just jealous 😅

[@johnthomas338]

5:20 simply isn't true. If some of the panels were shaded, it would not lower the output of the other panels, because all solar panels manufactured in the past ten years have bypass diodes... He's talking as if bypass diodes don't exist.

[@matthewwakeling4978]

It's not as simple as that. If you have just a single string then you can still get problems with the total voltage being less than required by the inverter or battery charger. That can be prevented by making the normal operating voltage high enough so it will still work when a panel is out. However it's even worse if you have several strings in parallel, because the unshaded string will provide power at the full voltage but the shaded string won't be able to provide any power at all at that voltage, so a single shaded panel can stop an entire string producing power. A good MPPT converter will try to work out the best voltage to use, but it can't perform actual magic.

[@johnthomas338]

@@matthewwakeling4978 You are talking about two strings running parallel, nobody with any sense does that... You only have one string per MPPT. Your 'problem' is non-existent, because nobody with any sense would run two strings in parallel, you would buy two single MPPT inverters, or one dual MPPT inverter.

[@matthewwakeling4978]

@@johnthomas338 I agree with you. However neither message is being shouted from the rooftops. Certainly the Victron calculator doesn't warn you at all if the panel voltage is quite close to the minimum charging voltage, meaning a shaded panel would stop charging completely, and it also positively encourages parallel strings with a single MPPT charger.
