Thanks for putting this video out! I just upgraded my PV system to a 10kW Fronius Gen 24 inverter. Have not installed battery storage .... yet. Enjoyed learning more about the tech side of Fronius Gen24 inverter. Look forward to your review of the Fronius Gen24 and BYD Battery setup esp in real life operation and blackout situations, comparison with Tesla's Powerwall.
The have the best ;) The problem with adopting too many batteries is that you need to update and improve firmware and the integration. It’s much easier to focus and do 1 battery well than spread your focus and do multiple batteries half hearted.
Great video. Does the Fronius Gen24 inverter have Arc Fault Detection built in? I saw from the fronius website that some fronius snap inverters do, but not sure about the gen24.
Tesla Powerwall 3 will have 6 independent MPP inputs and I live in Austria near Fronius 10km (even considering working for them as a engineer) I really want to use them but with only 2 MPPs it’s sadly a no go and a maximum of 10kVA for hybrid is little bit boring..
6mppt?! Mind blown. But, like I said in the video, more mppt’s are not necessarily better. Efficiency losses, increased expense in the wrong place. I’d rather an inverter with a great mppt and 2 algorithms than an inverter with an average mppt and 6 algorithms. Tesla may be awesome. Can’t wait to test it.
I recently had a Fronius system installed and am very happy with it, but of course for me, it's early days. As you know, the inverter can supply a power point in the event of a blackout. I am an electrical contractor and have installed quite a few changeover switches and inlets for generator connections to the house. Is there any reason not to feed the inverter pv point supply back into the house via a changeover switch?
Hey, good question. It’s possible but it’s only 3kW max. An upgrade is hopefully coming where the PV point will be permanently on. So leave your fridge and another gpo on permanent Pv point. It will take an extra pcb in the inverter, but nice idea for some
@@mcelectrical Thanks for that info. Yes, I realise the limitations but the parts aren't too costly and my labour is free, more of a convenience thing really. If I went down that route would I need to limit my draw with perhaps a 10A MCB, or will the inverter safely limit the draw, without damaging itself? Cheers.
Make sure you get the Eps side correct tie the netrual down to earth so you don't have floating 😉 do at change over switch. Australian to UK code is different as at the change over the netrual remains connected unlike UK change over switches
@@mcelectrical is this years of R&D you was talking in the video where you explained the difference in price for a plus inverter? Once II made decision to nut Fronius. Now I again started to think of buying it and I see their "years of R&D" which looks like a student work. No 24/7 backup line, no https support and people saying the Fronius quite often breaks right after warranty expires. This makes me think that all R&D money went for last feature to break after warranty expires.
Great vid. Where I am, Fronius isn't available. Sungrow is. I have a 25kw on-grid system but I need to go hybrid. Since it's a fairly big system, would a Sungrow SH25t be a good idea?
I don't quite understand the storm mode stuff... as a matter of course, wouldn't any excess solar generation be used to continuously top up the battery (before any more excess is sent back to the grid), making a storm mode unnecessary?
Let’s say it’s a rainy day, 3pm and your battery is flat. You know a massive storm is coming and you want power. Hit storm mode and you battery will charge from the grid. However, utilities like Energex don’t like the idea of this massive increase in demand on the grid, so technically, you’re often not allowed to do it.
@@mcelectrical Ah, of course. Thanks for the reply to a fairly dumb question! If only you guys were here in Melbourne; I'm struggling to find an installer who'll recommend Fronius/BYD over SolarEdge. Everyone keeps repeating "Fronius is no good, one shaded panel and the whole string goes out...".
There is no reason for either. But if i had to choose one I would go tigo with fronius then take the tigo off so it doesn’t interfere with the fromius mppt. :)
Hello, thank you for the very informative video. How much would it cost to upgrade Fronius Primo GEN24 to the Plus version? Is it a flat rate for every model or price scales with the power of the inverter? Is it possible for tech savvy individual to do this upgrade?
You would only do it when you install a battery, and normally get your installer to do that. It’s about $800 depending on size. A dozen companies that are Fronius Solution Partners PLUS (like MC electrical) get fairly good discounts on that. Where do you live?
@@mcelectrical Thank you for the reply. I live in Northern Nevada USA, it looks like Fronius US has certificate program going to become a partner which will provide all the knowledge I miss.
You couldn’t make the question easier. Penrith solar are honestly the best. The owner Jake and I work closely together on how to do solar better. I’ve been to his factory several times. It’s mind blowing. There is one small issue. Jake loves enphase as much as I love fronius. He only installs enphase. But. Here it the point. Installation company is way more important than product. Although I disagree with Jake on product choice, I’ll back him every day as an installer. ua-cam.com/video/Bw2AMwxPGqg/v-deo.htmlsi=CVyTTdwTxO4sUT0o
Thank you great video, I wish you asked when/if Fronius will get the change over time for the Fronius 24 and BYD battery combo down to the same as a Tesla Battery in a black out, currently my system takes around 20-30 seconds. PS I do have the latest firmware installed on the inverter.
Thanks Grant! Mark mentions Fronius is working on reducing it for a future firmware update here: ua-cam.com/video/MJJexnop6Xw/v-deo.html and he also weighs the pros and cons of a quick changeover time versus a slower time. Some might prefer the slower changeover time for good reason...
Love your vids think we are overdue for another, when are we going to here you on the solar podcast with old mate from solar analytics and the istore fella
For best fire safety: Inverter with arc detection & tigos with rapid shutdown. I just got more 10 x410w wall panels, those are with tigos + 8 ground mount panels with tigos.. 16 panels in roof , without tigos.
Short answer is tech support and updates. Fronius are serious about both. Firmware is often updated on inverters and the relationship between the battery and the inverter manufacturer is crucial. Ideally we would just have a fronius battery. But I’d rather have fronius+byd than Sungrow+Sungrow for example. (Lg by the way isn’t really an option with fronius.)
I can definitely recomend the gen 24. It is self evidently more efficient than our older SMA. Both excellent brands though reliability wise. I dont mind the slow change over in black out's. It lets me know there is a blackout in progress. We have tested the inverters output in blackout up to its maximum of 6kw succesfully but we try to avoid working the batteries to hard. Its not a true off grid inverter but we have had blackouts beyond 24 hours and it coped just fine.
I run three single phase Fronius Primos 8.2KW per unit since November 2023. The whole system install/upgrade was delayed as the Primos were on back order and my Installer (who I trust) suggested other type of Inverters. This was the only time that I insisted on the Primos. They have been around for a long time and have proven reliable. Yes, the fans make a bit of noise and I was fully aware of that before picking them. But it's nowhere near as bad as some make it out to be. In regards to noise, they are on par or even less noisy then the fans on my two Selectronic SP Pro's 482/7.5KW. Also I have a real dislike of Manufacturers now removing front Panel LCD Displays. That is just cost cutting. They have always been extremely handy to an instantaneous look plus most have/had the options to verify or change settings without having to go and having to pull out Laptops etc. All My previous Inverters had LCD Displays: SMA Sunny Boy, Kaco 4.2 and now Fronius Primo's 8.2KW
I have a comment about step 7. Cybersecurity of this discussion. I dont understand why Fronius does not support encrypted network traffic within the local network. The only way I can connect directly to the Fronius inverter (not over their portal) within the local network is using open (un-encrypted) http traffic. This for 2024 shocks me. (it would be a welcome security improvement to have https in the next update).
Few months back I wanted to buy Fronius. Then after reading that it get broken quite often right after the warranty I decided not to buy. Then I decided few day ago give it a try and watching again and the fact it doesn't support https tells me that there was no any years of R&D like they were talking in previous video. Who today in 2024 uses http? I also question that easy setup with a button. If someone from the street comes and connects your inverter to his wifi hotspot?
I think the storm modes will eventually need to be controlled via Dynamic Exports (DNSP), if everyone hits storm mode at the same time and starts to import along with ev's charging that could cause issues with the grid.
Fronius have some weird lacking features: lack of MPPT inputs - 10kw 3 phase only allows 2 strings on MPPT 1, but only 1 string on MPPT 2 - that's just stupid. It also doesn't offer a 3 MPPT single phase 10kw model, which is limited if you want East, North and West arrays or have complex rooves. So many of my customers have been forced to choose alternate brands because the lack of MPPT options.
Thanks Markus, interesting comment. Here’s my take… The idea for a need for 3mppt’s is a bit misguided. Here is my old explanation. mcelectrical.com.au/solar-panel-design-north-east-west/ I’ve tested this setup with goodwe 3 mppt vs fronius with uneven shade on the parallel. Fronius works better just because of its mppt algorithm. Fromius are adamant that 3mppts just cause inefficiencies and expense. I tend to agree. You are right that there are some theoretical limitations. That’s why I tested the 3 mppt on goodwe v fromius. In reality, we have never had the need to opt for goodwe rather than a 2 mppt fronius. Quality build and quality mppt algorithms trump an extra mppt.
@@mcelectrical Yeah, but if you have 3 strings of unequal panels (different VOCs) then you can't double them up on the same MPPT. I'm not talking about shading. The last job that the customer, who really wanted to roll with Fronius (and my father was Austrian so I have a soft spot for Austrian products), had a North West deck roof with 8 degrees tilt, 8x 500W Longi, North East house roof 22 degrees tilt, 7x 500W Longi panels and North West house roof, 22 degrees tilt, 8x 250W panels. House only has single phase and customer wanted as close to 10kW as they could get. How could you maximise this with a Fronius? The roof has zero shading! Would you drop the deck roof to 7x panels and put the 2x strings with 7x 500w on MPPT 1? Or am I wrong?
Well not its software. My Fronius monitoring system disconnects itself from my router at least once a week. Lots of complaints about this online. The app is ok but others are still better. The inverter hardware seems solid 1 year in.
I had this problem and tried many fixes including assigning a static IP address at the modem. I run a TP Link Mesh system (X68). I have my Gen24 mounted outside on a car port wall. When I placed a mesh node directly opposite on the inside double brick wall this fix the issue totally, will even reset link with power failure. The inverter does need a very strong WiFi signal, this maybe caused by overlapping WiFi channels.
Yes. the app is very slow. Then you have to buy a consumption monitor and then your expected to pay a subscription to view more than 3 days of its history. Especially when you never use to need a subscription to get it on the old app. Which was a better app
Yeh, I was talking with rod about this last week. He is personally working on it. Apparently many of the issues were solved with a firmware update. We don’t seem to have many issues but there are real issues and it’s sporadic.
A friend of mine noticed it straight away, the inverter drops DHCP address, not sure why. Assigning a static address stopped it dropping. He has granular monitoring with Home Assistant, ever since static was assigned its been ok. I don't monitor mine as close as he does so I haven't noticed :)...
I don't mind my fan noise , I know when it working hard. Fan is going great . Fronius International 5kw. Just would like a check over one day. Ps Winaco panels 👌
If your solar company is a Fronius Solutions Partners Plus, you'll have a 10-year warranty on labour and parts. More on that here: mcelectrical.com.au/why-fronius-solutions-partners-plus-matters-fsp/
Should have asked the question why a premium expensive brand offers such a poor warranty on products "designed for 30 years service". 5+5 needs to go and Fronius needs to catch up with the rest of the industry and offer a full 10yr warranty along with 3MPPT inverters.
I roughly covered 3mppt inverters. But in short I think it is such a niche product it’s not realistically worth it. As far as warranty goes, Fronius originally set the bar too high with 5+5. Every other manufacturer had to do one better. Fronius are more responsible than to chase crazy long warranties.
@@markcavanaghcan you do an in-depth video about GEN24 and BYD battery? Particular how it’s works, what it looks like in the app, can you sell to the grid, how to manage the battery. I liked your video about the BYD battery options.
Hi @@twinrotors . There are improvements coming to the gen24 app interface for Byd. When that comes out I plan to do a video along the lines you mentioned.
I have GEN24 for 2 years, the first year without problems, the second every two or three months an error appears (the manufacturer does not know what the error is) and a problem with WiFi as well. With a new modem, the distance is even 5 m. Reset unit everything returns to normal. And adding a 7.1KW battery for 12+ thousand is a rip-off in broad daylight. Apart from that, it is a good inverter, maybe it just happened to me, who knows?🤣
It is not better! It is junk just because design was made so poor. I'm speaking about 3phase Fronius. It requires exactly 3 phases, while in theory it could work only having one phase and the rest could be taken from solar if not enough or solar not stable. Why on earth you would want do an expensive 3 phase upgrade when you actually need less dependence on the grid? If it can work full backup when no grid power then I have a question why on earth I would need to connect it to all 3 phases? Why it can't just work of one phase? This makes no sense as upgrade to 3 phases cost more then the cost of the 3 phase inverter 10kWh. This is so stupid. I was thinking I found a good one, but this was a show stopper for me and I have to start looking for something else. What a disappointment.
This is why MCE never call prospective customers back, they are too busy making youtube videos... of course the "we'll call you within one business day" might be one business day after they finalise their socials videos
Hmm, that’s disappointing. I’d be keen to hear more details. We are in a transitional stage with our “first on call” at the moment. But that’s no excuse.
I sent a request through for information on my way to coffee. I received two phone calls while at coffee. By the time I got home I had a detailed estimate in my email. The service was professional, friendly, knowledgeable and based on my needs. First class all round.
@@mikeroberts786 your lucky.... I sent a msg on Wednesday 25/10 around middle of day, I got an Email of all things at 10am 26/10 telling me someone will call within a day (really? took the time to email me to tell me theyll call, rather than just calling there and then) , its now 12/11 and I've still not had that call, probably because I needed a service call (to check our 10yo-ish panels as I suspect they are not performing) rather than an install job worth 10K... I gave them a full week to get back to me before I moved on and called someone else.

If your solar company is a Fronius Solutions Partners Plus, you'll have a 10-year warranty on labour and parts. More on that here: mcelectrical.com.au/why-fronius-solutions-partners-plus-matters-fsp/
Should have asked the question why a premium expensive brand offers such a poor warranty on products "designed for 30 years service". 5+5 needs to go and Fronius needs to catch up with the rest of the industry and offer a full 10yr warranty along with 3MPPT inverters.
I roughly covered 3mppt inverters. But in short I think it is such a niche product it’s not realistically worth it. As far as warranty goes, Fronius originally set the bar too high with 5+5. Every other manufacturer had to do one better. Fronius are more responsible than to chase crazy long warranties.
I would still buy a Toyota with a 3 year warranty over a Hyundai with a 10 year warranty. The old European inverter brands have proven reliability.
@@markcavanaghcan you do an in-depth video about GEN24 and BYD battery? Particular how it’s works, what it looks like in the app, can you sell to the grid, how to manage the battery. I liked your video about the BYD battery options.
Hi @@twinrotors . There are improvements coming to the gen24 app interface for Byd. When that comes out I plan to do a video along the lines you mentioned.
Deye buy deye is half the price on battery and dont pay extra subscription on your smart meter to show you data😅😅
I have GEN24 for 2 years, the first year without problems, the second every two or three months an error appears (the manufacturer does not know what the error is) and a problem with WiFi as well. With a new modem, the distance is even 5 m. Reset unit everything returns to normal. And adding a 7.1KW battery for 12+ thousand is a rip-off in broad daylight. Apart from that, it is a good inverter, maybe it just happened to me, who knows?🤣
It is not better! It is junk just because design was made so poor. I'm speaking about 3phase Fronius. It requires exactly 3 phases, while in theory it could work only having one phase and the rest could be taken from solar if not enough or solar not stable. Why on earth you would want do an expensive 3 phase upgrade when you actually need less dependence on the grid? If it can work full backup when no grid power then I have a question why on earth I would need to connect it to all 3 phases? Why it can't just work of one phase? This makes no sense as upgrade to 3 phases cost more then the cost of the 3 phase inverter 10kWh. This is so stupid. I was thinking I found a good one, but this was a show stopper for me and I have to start looking for something else. What a disappointment.
It'll be interesting when the PowerWall 3 comes out with the built in inverter & battery?
Then the Fronius vs Tesla PW3 war will begin.
I hope the Tesla inverter is as good as their battery. Actually I can’t imagine that it will be that good, but I’m hopeful.
This is why MCE never call prospective customers back, they are too busy making youtube videos... of course the "we'll call you within one business day" might be one business day after they finalise their socials videos
Hmm, that’s disappointing. I’d be keen to hear more details. We are in a transitional stage with our “first on call” at the moment. But that’s no excuse.
I sent a request through for information on my way to coffee. I received two phone calls while at coffee. By the time I got home I had a detailed estimate in my email. The service was professional, friendly, knowledgeable and based on my needs. First class all round.
@@mikeroberts786 your lucky.... I sent a msg on Wednesday 25/10 around middle of day, I got an Email of all things at 10am 26/10 telling me someone will call within a day (really? took the time to email me to tell me theyll call, rather than just calling there and then) , its now 12/11 and I've still not had that call, probably because I needed a service call (to check our 10yo-ish panels as I suspect they are not performing) rather than an install job worth 10K... I gave them a full week to get back to me before I moved on and called someone else.
@@markcavanagh details in my previous comment to Mike Roberts, you've lost us, but maybe you can address the issue with your staff to prevent other losses in the future.
@@Ressy66 ok thanks for the feedback.
