Vertex S+ 450W 22.5% max efficiency (but what is the min guarantee?) JA78S10 450W 20.7% efficiency (max min median, not spec on the datasheets) product and power warranty Vertex S+ JA I-V Curves Vertex JA Power-Voltage Vertex S+ JA I cannot find Ampage at different light...

So you mean this curve Below is Vertex Then I believe I need to compare apple with apple. ie the JA curve is for a 540W panels while the curves one is for a 440W therefore it is to be expected that the curve for JA will be higher. Therefore such curves should be compared for panels with...

Hello I came across this brand I did not know (one more!) Here is the product infosheet https://static.trinasolar.com/sites/default/files/VertexS+_brochure_EN.pdf and datasheet...

I PMed you. Did you get it?

You don't know what I know or don't as the saying goes. So all suggestions are more than welcome :) Thank you :)

So the EDDI is multi-purpose ;)

As someone mentioned above, They are not in the same league. It is different products. I have something called Power Diverter since 2016 and a part of replacing, every 2 years, the batteries of the sensor where the CT clamp is, it is has been so far hassle free It has only one purpose which...

Hello @bladerunnerpv Unfortunately, being MSC, RECC, EPVS or HIES registered is not a guarantee of competence and reliability. All the companies I contacted in the past 12 months were MSC and some HIES and I have described above the issues I had. As @binky said, it is likely they can't be...

Thanks, Binky, What do you mean? learning job for me or a learning job for the installer? I would like to avoid having to deal with an inexperienced installer. I have not forgotten my promise (made about a year ago) to post photos of the installation. I did not expect after 12 months I would...

Hello, I am trying to find an installer who is technically competent and who can communicate (ie explain in simple terms the technical decisions of his design/solution and how it should perform etc....) Attached you'll see a very simplified diagram that shows my current installation and what I...

Hi MM7769 Sorry to hear that. Where did you find out others were also having problems with this brand and who did the installation? Hopefully, this will be quickly sorted. Please keep us posted. Many people report their success story, or just that they had problems and it is very difficult...

This is what happens when one is too slow !!

That's a good start :) Thanks regarding my DNO application. I think my installer can't articulate things. He sent me an update with 3 points. He now wants to replace my existing inverter (he did not say why. I can imagine it is to keep all the equipment with all the same manufacturer), and...

Thanks Binky for the clarification. Before getting involved with Solar I never heard of the brand except those who do other things like Samsung, Sharp, Toshiba. Anyway, what do you know/think of Huawei regarding inverter, optimizer and batteries? Here a recorded webminar about Huawei.

You are right.Premium and reliability are not synonyms unfortunately As for 'best' and all those not that independent reviews it is very difficult to know who to trust. Thus me asking here what people think. Thanks

Hello Binky following your statement then so are Solax, Sunsynk, Pylontech, SAJ, Omnik, Onesto, Solis, Growatt, Sofar, Fronins, Sofar, Victron, SMA, Goodwee, Sungrow…. Just on top of my head. Would you say the same about car then? I am pretty sure they do not all play in the same category...

Hi When it comes to car, I would with confidence say that a majority of people know that Mercedes, BMW and Audi are considered premium brands unlike the like of Peugeot, Vauxhall, Renault When it comes to our favorite industry, I still have not been able to figure out what brands are premium...

Hi Binky how/where can I read more about this. I still do not understand the implication vs everything I read/learnt so far I get that there is a maximum power that can go to the grid. What I do not get is all the conversations about setting the inverter so it can only export up to a limit to...

can't my existing inverter be connected to the hybrid inverter and therefore there is only one "point of contact" with the grid?

Thanks Andy for your quick response I still do not understand why the DNO is interested in the batteries when the link between my system and the grid is the inverter. What is the point of having settings to limit the export to fulfill DNO's requirement if that does not seem to be the criteria...
