Indeed. @frasere2, read from this post onwards. The IQ8HC will max out when the panels are operating at 86.3% of their efficiency. First, they'll never operate at 100% efficiency, and probably closer to 80-90% maximum given their orientation. Second, they degrade over time, so even if there is...

Just by way of an update, I contacted Enphase to ask questions around their compatibility calculator, and they responded. This is what I asked them: This was their reply: I checked the compatibility, and the panel I'm getting is compatible with all IQ8 models (see attached). I've already...

No, but this is an interesting point. Higher-rated electronics is going to last a lot longer than lower-rated electronics operating at the same power level. That's just common sense! I agree. But this still doesn't answer why Enphase themselves think IQ8AC is appropriate, and that was without...

I had a reply. It will be €10 more per microinverter for IQ8HC. So, €220 extra on a total cost of €12,535. But here's what he said (paraphrased). He said that the peak power of solar panels is not achieved at all in an east-west orientation, and it will reach a maximum of 70%. So, 440W x 70% =...

Thanks, @SeaGal, and this was my thought also regarding the sun's position at different times. In my case, I will have southeast-facing panels and northwest-facing panels. Therefore, the southeast ones will definitely get direct sun in the morning. I've just emailed the supplier about this...

Update. I pulled the trigger on this, and went for Enphase with 22 Hyundai HiT-H440MF-FB panels (HJT technology). The supplier has suggested the Enphase IQ8AC. I questioned why not the IQ8HC given that the Enphase microinverters are generally underpowered for most high-Wp panels, but the...

Yes, I looked at SMA after your earlier message (sorry, I forgot to reply specifically as the topic had taken an unusual turn at that point), and I note one of my suppliers (out of 18) did offer the Sunny Tripower 5.0 together with SunPower Maxeon 3 panels which are uber expensive. But it...

I read the entire topic, the entire blog, and many of the recent comments. And compounded with my existing doubts about SolarEdge (I was aware of failure rates, but assumed they'd be on top of it by now; the negative sentiment around the value of optimisers in this forum; having to think about...

Then we're fellow IET members. We should be more respectful of each other. OK, it seems we're singing from different datasheets. The HD-Wave has been superseded. On offer now are the Home Hub, Home Wave (HD-Wave rehashed), and Home Short String inverters. I mentioned at the start of the part of...

@SeaGal Apology accepted, but just some clarifications... The University of Nottingham (the uni I went to) offers three similar courses: Electrical Engineering, Electronic Engineering, Electrical and Electronic Engineering. Each course includes modules in both electrical and electronic...

Pretty sure professional installers won't take my instructions on electrics that I got from ChatGPT or in any case, so calm yourself. But I also have electrical qualifications higher than yours, so don't worry. There's no guesswork here. Btw, the landing page of ChatGPT says at the bottom...

How rude. Not sure if my reference to ChatGPT should result in an entire discussion about its value. I use an array of sources including ChatGPT, salespeople and installers from multiple suppliers, Google (leading to various blogs, articles, etc.), manufacturer websites and datasheets...

So, I'm now at a stage where I'm considering SolarEdge string inverter again over Enphase microinverters. I also read this very interesting topic by @FilterGuy who did an analysis on MPPT controller in series considering bypass diodes and shading. While the topic in the end wasn't conclusive...

I've recently been getting sold SolarEdge string inverters a lot more by some suppliers which enticed me to have another look at them based on the MPPT and MLPE concepts which mitigate shading and allow per-panel monitoring. I've updated the link to this in my earlier message as the original...

From what I can see here, it looks like it's just one battery for multiple microinverters. However, a supplier told me that batteries are a waste of money at present because of net metering in the Netherlands. For at least the next two years, residents get full credit for returned power to the...

Thanks for the replies once again, and the warm welcome. Yes, I am definitely going to buy a battery to go with my installation, as @Hedges and @houseofancients mentioned you opted for. I'm quite set on microinverters for the reasons mentioned in my previous post, but Enphase IQ8MC seems to be...

Thanks for your reply, and the warm welcome. b) I agree that an extra panel will provide more power than getting the tilt exactly right, but my configuration is such that the number of rows I can get is the same regardless of tilt (20° ±10°) as the distance between them is maximised for my roof...

I am planning a flat rooftop installation of 14-16 panels with microinverters for my home. I have done research and considered sun elevation, azimuth angle, and run simulations in PVsyst. The best option for my roof is a 20° tilt. I live in the Netherlands, and I am considering various quotes...
