Thank you for your great content. I have more than 15 years of experience in the industry and love seeing someone really explaining things and not just waving around with slogans

Interesting as always! Thanks Mark, keep 'm coming!

You put a huge amount of effort into the testing scenarios here, it's much appreciated. Great work.

Mark, I really appreciate the efforts you go through to get a thorough understanding and then pass this on!

Welcome Peter, Glad to help!

In my case, the shade creeping up from the panel’s bottom from mid afternoon due to tall street trees made this video very relevant (complicated by the string being in parallel with another string). I had considered adding microinverters to this string (although a 10% gain would be unlikely to offset the cost I think). Thanks for the real world testing you are conducting. Cheers

Nice balanced assessment, mixing in the theoretical with the emperical.

Great content!, thanks for sharing all of this. I'm looking forward to diving deeper into more of your stuff!

Your videos are fantastic.

First things first: kudos for your down to earth research! ... for which I have an idea for another round of optimizer vs. string shot-out: what happens with "soft" shading (tree branch) which is all over some of the modules?

Fantastic videos

I truly believe an Enphase Energy system to be the Apple of the energy arena. My Enphase 20,000-Watt AC system has worked 99% since 2013 - true reliability! Can't wait for IQ8 PV. Great job, Mrk. Cheers :-)

I hate apple because its all just marketing and looks. Apple provides less performance for money. It provides no compatibility. What it does provide is looks and a trendy image. Now, i agree that many people advocate for Enphase without much thought, simply wanting to believe its always the best, or worse, wanting their customers to believe that. But i wouldn't want to put Enphase down that much as to compare it with Apple.

what if you have one or two pv panels completely in the shadow wil it bring the whole system down in a string inverter system.

Nice

Hello, I need english subtitles or transcription, in the fist video there was, but in this not, thanks

Thanks! The ideal would be to have panels constructed with integrated inverters, an inverter for each cell in the panel. Such inverters would be very small, on the order of a single-chip solution.

Does it matter if you have the panels on either side of the roof (east and west) when you're installing a Fronius inverter?

Hello Mark, with a view to a future expansion of my installation (affected by the shadow of a chimney), could you explain to us if installing panels in parallel to manage shadows is an interesting solution? for example, 4+4 panels in parallel in the same mppt, 4 panels are affected by a shadow from a chimney while the other 4 panels have no shadow. Would it be more interesting to put microinverters or make the 4+4 parallel with Fronius? Thanks in advance

@mcelectrical

Hey Jan, this is a great question. In my tests, if you parallel Fronius and shade one of the parallel strings, Fronius performs ridiculously well. But, If that string was as short as 4 panels, then it would have issues because of lower string voltage when shaded. So if possible I’d go a string of 8. Almost always Fronius is as good as enphase, but maybe this is an enphase situation. I’d have to see the layout. Mark

Hi, wich optimizers go with fronius? Tigo or nothing?

Nothing. They are not needed with fronius, and, they are a useless company anyway. mcelectrical.com.au/tigo-optimiser-recall/

From your video It sounds like the inverter can control how the bypass diod is working how can that be possible?

@Rooster-Creations

2 жыл бұрын

It is done by the MPP-tracker. This MPPT will vary the load on the panels, causing the diodes to engage (low load => high current) or not engage, (higher load => lower current).

Who is installing panels next to the shade of an adjoining building so the shade is even across all panels like in you display. Usually trees are the issue, where it might block out the first four panels completely. Do the test on this an it will show Enphase is far superior. Yes Every system (String/Optimised) can handle a certain amount of shade, but in certain situations it Enphase or nothing

Ok

What is the point, the cost difference is more than 10% and will not payback at a cost effective rate.
