Ah yeh sorry, was a delay in editing. It’s about a week away

We did Sungrow in the past, about 180 inverters from memory. I just found the failure rate and bugs too high compared to Fronius. I’ve also asked a several of people what they think about the Sungrow battery after installing a lot of them. Not all, but most said there were too many issues. Have you had the opposite experience with Sungrow?

​@@mcelectrical I hope we will not make a bad experience with the new System from Sungrow (ordered). Due to the 180 Systems you mentioned, i think most of them were old SHXXRT and old SBR Battery series, not the new ones. Never heard about problems from users so far. If you want to stay in one ecosystem with all restrictions fronius is great, but we want to use "EVCC" or "CleverPV" EMS with a 3rd party Wallbox for way more options, customisation & home automatisation. And its a bummer if you have 20+kwp + 3 Strings on your roof and no suitable fronius hybrid inverter. If they had "bigger" Inverters maybe we would've chosen fronius. Do you have any tip/bugfix, regarding sungrow, which fixed most of the problems you encountered?

Interesting. Why? What if fronius Brings out their own battery?

@@mcelectrical When it comes to the world's largest electric vehicle manufacturer, which produces its own batteries and outsells TESLA, There is nothing interesting left.

Yeh that doesn’t add up. Maybe the same price for byd, but not $5500 less. Is the company Tesla accredited?

@@mcelectrical Thanks for the reply. They are an Australia wide company & thier site says Tesla Certified Installer ( & Premium Installer) so I guess that means accredited?

Ok, the pricing is odd. I’d generally steer away from Australia wide installers - because you’d more than likely end up with Subcontractors. Look for someone local and I think you’ll get a more realistic price.

That much price difference is odd as Fronius and BYD is quite costly themselves! Cheaper or atleast on par there and there about should be ideal price. Unless we're talking about 3Phase Installation etc

Yeh I don’t get his “dark maga” move. But I put that aside and look at the product. It’s just better.

Unfortunately Alternatives ain't that good either, Most of them being Chinese

It would work great, but you would be buying the solar inverter in the pw3 for no reason. For Enphase, try and get a Tesla Powerwall 2 before they are all sold out ( like, next week)

@@mcelectrical Isn't limit on AC input to the PW3 lower than DC input? For ppl with large microinverter equipped PV system this could be an issue.

Hey, thanks for your comment. Do you mean to say SolPlanet is good? Always keen to hear another point of view :)

The real question is, how long till fronius has a battery!

@@mcelectrical they had one a while back😂

You’d be much better off going BYD /Fronius if you are 3 phase. Or waiting till Tesla bring out 3 phase - but that’s likely more than a year away.

Interesting! I’m assuming you are using an oscilloscope to measure this? I’ll have to check that out!

@@mcelectrical Yes, I've got a graphical multimeter which also has an oscilloscope feature. The PW output isn't very smooth, you can make out steps in the wave, which isn't present in better quality inverters.

I have three TVs in my house...and none of them have issues when the house is running on the battery.

@@Kiwigeo8339 I only have a problem with one TV, everything else runs fine. Anyway, it's only during an outage a night when there is no grid connection and it's running on the PW. For normal grid connected powering the house at night, it's fine.

Maybe they've done better job with Inverters in PW3 as it has an integrated inverter

We’ve installed about 170 Sungrow inverters. The failure rate and the tech issues we’ve had with them was too high, so we stopped selling them. I’ve also talk to a lot of guys in the industry that have had heaps of issues with the Sungrow battery. I don’t think it’s the worst solution out there, it’s just a long way from fronius /byd or Tesla.

@@mcelectrical cheers, I'll see how I go.

I think the Sigenergy has a DC-DC option. If you want to be able to use your car to charge your home battery, nothing else is even close. If you want whole home backup and charge on solar, the Powerwall 3 is really incredible. I don't live in Australia, but I understand that going solar can be mostly free because of the incentives. DC has to be turned to AC at some point to power your house, and I think the Powerwall is the best option for nearly all homeowners.

We get a fair few customers who sell their homes and transfer the login details. The new owner will contact us - yes the warranty transfers. But yeh I guess if the details are not handed over in the sale, then it’s lost.

Nope. Good point. But to be fair, manufacturers often do accelerated testing to simulate a longer time. That’s not exactly what they do with panels but there are a lot of tests that they need to pass like hail, wind, humidity. 25 years is still a joke.

Just curious where you found that deal/price? I'm doing a new house build and that's what I would like.

Yeh, I’m not a fan of Sungrow anymore. From our experience, reliability of there inverters isn’t great. And although I haven’t installed their batteries, I’ve had several industry friends who install heaps of them tell me they have heaps of issues.

​​@garygreen5278 just realise you can when negotiating. Just paid any running for 2 week.

​@@mcelectricalsee how I go..

It’s a 10kw single phase inverter. It’s similar to the Fronius BYD cost, but the BYD solution is probably a bit more difficult to install, so total cost might be a bit more from BYD. But the features of the PW3 are significantly better - eg the user interface, discharge capability, footprint, flood proof, all in one warranty etc. That a good point, if it fails outside of 10 year warranty, then you may need buy a new one if not repairable.

It might not do everything, but from all reports lts a lot better than the every other battery user interface.

@@markcavanagh I don't think you guys have GivEnergy equipment yet do you? Also Fronius should be going live with their Solar Forecast software soon and they also have API connection (same as GivEnergy) allowing for things like Home Assistant or other types of plugins to control batteries. Another very decent app/control interface is PowerOcean EcoFlow. SigEnergy is another that comes to min as having more control. Finally Anker Solix X1 would appear to be a copy of Tesla's App - based on what I have seen on paper at least.

Sigenergy is better. Amazing development for renewables

3 phase will come, my feeling is it’s about year away.

Yeah, this price is ridiculous, I just got 15kwh Seplos kit for 1500GBP here, not ip rated with case I have, but cmon... I have ROI with it around 2y, with Tesla power wall is like 15, especially considering Tesla does not sell them directly and it should be installed by "professional" which adds another few grounds on top. Don't get me wrong, PW3 is fantastic product with its sw integrations and quality, but it is just doesn't make much financial sense.

I like the way you think :)

Ha, Goodwe is ok. Probably in my list of top 5. But, yeh, don’t go with a goodwe batrery. Replace it with a Powerwall and maybe upgrade your solar at the same time.

The testing will start soon. It will be interesting!

That's one of many features. The Catch Control has levelled up recently to cover a few new use cases, more on it here: www.catchpower.com.au/catchcontrol

Thanks Glen, appreciate your feedback!

Sorry to hear that there's a lack of information for you. A BYD wouldn't work with your micro inverter system as it's a DC-coupled battery, but any AC-coupled battery could be retrofitted, like the Tesla Powerwall 2 (while it's still available). Enphase has their own battery as well.

They are doing well, I am based in Australia and see them achieving great sales volume in rooftop and utility scale segments!

I haven’t seem much of them either. Unsure

Understandable, part 2 will be out soon. Hit the subscribe bell 🔔 to get notified when it's uploaded.

Thanks Magician man! Yeh I tested them years ago and saw a bit of gain on a decent tilt frame with a reflective roof. The more reflective the better, so I actually used foil “emergency blankets and got maybe 5 percent gain from Memory. I’m sure one will come to market soon that I’m interested in. Generally they are more a commercial panel. Solar farms or at least mounted on tilt frames with a reflective roof. You might see a percent gain on a residential roof- but I can’t imagine it would be much more than that.

Should come out in the next week. It’s pretty interesting

Great to hear, thanks for the feedback.

Thanks Gary, appreciate your feedback. Mark's results in Part 2 will be out soon.

Hey Gary, thanks. Always enjoy watching your videos too!

Sounds about right. I don’t normally think in m2 because the jigsaw pieces are large. But yeh sounds about right

Oh absolutely! We’ve done several jobs over the years where customers have vouched for the insulation advantage after the fact, especially in a baby’s nursing room in the attic

@@mcelectrical yes if the attic is occupied or used, then it is a feature that should be measured. Your rooftop test areas could be tested. Ask the university or TAFE colleges to get their technical people to run a trial. Energy savings is measurable. I would be very interested. ROI, return on investment, is quoted by new owners 😀 😄 Every aspect to rooftop PV must be promoted. Big mouths are pushing nuclear electricity. What they ignore is their cashflow crashes when the sunshines 🌞 Crashes all day and all night long with a Battery. With V2G BVs oversized battery parked 23hrs every day and all night long then nuclear will be screwing the government for their profit guarantee.

Nice. You definitely got the inverter right. And it wouldn’t be a mistake to install a panel like Aiko.

TOPHiKu6 CS6. 1-54TD- 465

I looked into that and I think the answer on paper is yes. They pass the same testing. But, I agree with your skepticism if that’s what I’m hearing:)

The Wattpilot's a good option if you're already in the Fronius eco system, but Evnex is a worthy contender in Mark's tests for derating. Mark recently filmed another video comparing 6 chargers which will be out in the coming weeks.

@@mcelectrical hitting that subscribe button now so I know when that video comes out :)

Hi Nathan, I know it might seem a stretch, but it’s our real figures. Keen to hear if others have opposite numbers

You might be interested to know that we have recommended and installed Canadian Solar panels for a long time. We've had good experience with them in the long run compared to other solar panels. They come from China for the Australian market, so we're not anti-China. Our focus is on build quality, and sometimes, we find certain regions are better for that than others.

No you don't need the Fronius inverter, you'll need an AC-coupled battery like the Tesla Powerwall 2, not a DC-coupled battery like BYD.

@@mcelectrical So if I want the BYD battery I can use the Fronius Inverter or do you mean that since I've got micro inverters, DC coupled batteries are totally off the table??

Hi Daniel, if your Sungrow inverter is running then it will be connected to the grid. It needs to Mimic the grid voltages and frequency in order to run.
