The least I can do is share my experience, so yes I will and will answer all the questions to the best of my capabilities. I have learnt a fair bit or so I will transfer my knowledge as I go along :) I am currently waiting for the designer to make the final proposal.

I think the advantage could be mainly on safety because there will be fewer amps in the system while delivering the same power. As for the sma-sunny article. well, it does not say anything about HV really or how it compares with LV. It mainly focus on DC coupled vs AC coupled batteries. They...

The inverter that was quote for my to be system ie 10 new PV panels on an 2 string inverter 11 new PV panels with microinverter 2 x 5.8kWh HV Batteries Batteries to be charged from the new panels, my existing 4kWp and from the grid was a X1-BOOST G3 (see attached datasheet) When I asked to...

Thanks @bladerunnerpv This is exactly what I have started to do. Build some boxes to the dimensions of the devices. I start to be used to it. I have done something similar for the PV Panels for the flat roof (space and shade) lol. As for the charge/discharge you are correct for one batteries...

Thanks for your detailed response. , I had read those manuals but it was not clear to me if the recommended length/distance were just recommendation or minimum requirements or something to strictly follow I realized I have missed an information!!! Thank you for bringing it to my attention...

Hi all, I am struggling to find enough space to fit the batteries. Even if I am buying 2 to start with, I want my system to be modular and be able to cope with more batteries without having to redesign it. The brand I am looking at is Solax with their HV batteries. The standard installation go...

For those of you keen to learn, I thought a bit of history with an insight into the future could be a good way to finish the year https://techxplore.com/news/2022-12-re-awakening-world-solar-cells-indoor.html Enjoy!! and wishing you all a good new year eve and a good 2023 full of sun :)

Hi @johnb2713 I am joining a bit late. Sorry. Congratulations on your achievement. I know it has taken you a long time of research, many head hacks and perseverance. But now you have it!! Well done So what's the next project ;) ;)

Mightbe but as more and more people use PV with batteries. you'll be able to heat the water from the batteries whenever you like. Depending on how big your cylinder is it takes 1 to 3kWh to heat the water which is not that much. I prefer using the space available for PV than solar panels...

It will be clipping and that is not really an issue because the PV will only their max power only a few hours per years.. What this also means it that the power curve will be wider and despite the clipping, they will still generate more kWh than if the panels were providing 5kWp. Of course you...

If we had the same type of tariff as in France, I would probably not be investing so much in solar... Now I do hope that once I get my second system, prices will remain high for at least 10 years (I know it is selfish but when you invest you think of your ROI ;) )

In order to be able to connect it to the grid, which you will have, the installation must be verified by a MCS accredited person. You can do the installation yourself but you will need to get someone to sign it off (no offense but I assumed you are not MCS approved ;) )

Thanks Binky, Interesting stuff there.

I recognize Binky's approach. The bigger the better :)

@chris020 Welcome to the forum. The prices are very similar (less storage for Quote 1 as you pointed out) and in the ball park of what I would expect for the equipment listed. Have you read the technical specs of the products. Which panels have the highest efficiency? Do you understand the...

Letting the sun charge your batteries is, how to put it, the basics :) When I looked at the EPS, I too wanted to have all my house covered (including my electrical underfloor heating), I then realise it would not help because even if some batteries will have enough discharge power this would...

Hi, you are referring to EPS (Emergency Power System), This will kick off in case of a power cut. Be aware that they are designed to provide emergency power ie depending on your house you may have to create a circuit that includes (lights, fridge, freezer) and this is what the EPS will cover...

Wood? Na, this won't last long enough and not sure the installer will be happy if I tell him I made a frame in wood , please install the panels on it lol

I have found another brand FYI https://www.renogy.com/solar-panel-flat-roof-tilt-mount/ I want to put 2 pairs of panels in portrait mode and hope I can have a mount that will take 2 panels together so I just need to adjust 2 pairs rather than 4 individually. I wonder how strong the mount...

There are many discussions about which size of batteries should someone install. There is no answer that fits it all. It all depends on your consumption and what you want to do. I can tell you what I am doing I have a daily average of 15.5kWh (about 5 in Summer and 30 in Winter). I too am not...
