By October 2021 - there are now multiple 3-Phase Huawei Inverters from 5kW to 12kW and even up to 20kW. I have TIGO on SunPower modules with high voltage 60 to 70V - NO outage still 2015 !!!! I think TIGO is the best! I think Huawei PV products could be the next I am buying...... due the optimizers!
I agree with the other poster. The video is very informative but I just gave up because of the music. It is annoying Muzak and the other thing is, it is just too loud for the voiceover. If you are going to have music it needs to be much much quieter, but better still don’t have it while you are talking, before and after fine. Otherwise thank you for being so informative.
I'm not in your area but I do find your videos really interesting. I have panels on all 4 roof directions, two of which (SW & NW) are subject to partial shading from street trees. I did ask about optimisers/micro inverters prior to install but I was told that their cost didn't outweigh the gain you would get. Better to just install some extra panels and wear the losses from shading. I will await the next in this series and thanks for taking the time to inform us about the various products that are available. Cheers
Hey, yeh a cost analysis would be really difficult. If the shading is significant enough to engage a bypass diode anyway, then an optimiser is redundant. However, if the optimiser stops the bypass diode engaging, or more importantly stops the string from being dragged down for a decent part of the day then i could easily see optimiser paying for itself.
@@mcelectrical What would be interesting is a bit of a primer on what to look for in terms of whether an optimiser would be useful. I think the people interested in this aspect would likely have the Fronius Smartmeter (or similar) and could use the Analysis->History function and plot the the current and voltage of each MPPT for a good, sunny day. My understanding is that solar panels are (forgive my layman terms) constant voltage/variable current devices so a drop in voltage means that the shading is significant enough to engage the bypass diodes. The more difficult to diagnose situation is where the current drop is due to the lower light intensity from shading and the impact this has on the string overall. In my case, I have 3 strings into MPPT1 and two strings that suffer from shading (NW & SW) attached to MPPT2. Anyway, you're producing a good series so thanks for that and I look forward to the next instalment.
Hi Mark Here are a few comments - Firstly you are being too harsh on Huawei. I think it would have been fair to mention that most of Australia's 4G network is built using Huawei and New Zealand's Ultra-Fast Broadband network also uses Huawei equipment as part of the build. Customers in New Zealand are happy to have 100x the speed of the NBN in some cases. Ultimately Huawei have never actually been proven to be spying and any security concerns are with national-level communications infrastructure - nothing to do with consumer equipment and especially not solar. The 5G carrier equipment ban was on both ZTE and Huawei which both happen to be Chinese so its more about their headquarters than the equipment themselves. Trump was also largely a architect of this push-back against the Chinese and recently we are seeing a lot of anti-Trump press which calls into question some of his actions. Its hard to say if he was wrong or right as there is no real evidence either way although its safe to say that any push back was more in the interest of the balance of trade and they are not really taking into consideration consumers who are looking for good quality equipment that will have a positive environmental impact. Ultimately we all live in one world and if we are going to go down the rabbit hole of conspiracy theories then you can forget solar all together seeing as you could make the case that any electronic equipment could be used for all manner of wild theories. Spying on consumers via an inverter is not actually of any use (Google already harvest data for advertising via their smart speakers), if you were trying to sabotage Australia's power grid that would be ridiculous as we have plentiful gas and coal resources so could just ramp those up on demand and disconnect PV equipment from the internet. As you point out in Australia the installed base of consumer solar is not dominated by Huawei anyway - it would be the likes of Sungrow and Growatt that would be the most likely targets and that would achieve nothing. You are right to include the "rabbit hole" in your review but I think you need to dedicate the same air-time to debunking the theory. Given that ZTE and Huawei were the only two companies offering 5G carrier equipment to Australia and only their carrier 5G equipment was banned its somewhat ridiculous to tie it to solar. Huawei and ZTE 5G consumer equipment (dongles, handsets ect) is very much allowed and the carriers are happily selling it. You need to ask yourself if you would mention Q-Cells "dark" munitions' business in a review or that Sungrow and BYD (who partner with Fronius for batteries) are the residential PV equivalent of Huawei/ZTE in terms of being the dominant Chinese backed supplier in that residential battery/inverter vertical. Its clear that their is tension in the world however its crazy to think that if some person buys an inverter from one country vs another then all of a sudden it solves those issue or has any bearing on them. - Secondly I agree with you on batteries however that goes for all batteries on the market from Tesla, BYD, LG, Huawei, Ect - its hard to make them stack up and thankyou for pointing this out. Some of the other brands of hybrid inverter also make you run separate circuits for EPS. Given that our grids are pretty reliable it does not really make a lot of sense to rely on batteries and solar for use in blackouts. Its probably more a case of having some camping equipment, power banks, UPS and possibly a generator. It would be nice however to see some cost-effective solar-based options but I don't think any company has them at this point in time. - Thirdly Enphase is wildly popular even though you rightly point out (in other articles) that its really a niche product also and its not a great idea to have electronics on the roof. In a lot of cases you could use 2x Huawei 5kw or 6kw inverters, optimisers and you would have a great system that is cheaper and more reliable than SolarEdge or Enphase. SolarEdge also continue to sell strongly despite their drawbacks and that they are also realistically a niche product also made in China. When you have 2x Huawei single phase inverters you also wind up with the option to run 4x separate strings which gets around the 12.5A issue (which I agree is a problem in some cases unless you use the optimisers). I love it that you debunk some of the myths around needing to see the data individually from each panel. I have also yet to see any evidence that micro inverters or optimisers produce more power on a typical system seeing as PVEL testing proves otherwise. Whilst Enphase and SolarEdge of course continue to tout their systems as being superior SMA and Fronius cite counter evidence to the contrary that optimisers or micro's are not required if the system is properly designed (que you and your team who can do this). The real answer is somewhere in the middle that optimisers and micro's can generate a little extra output in some circumstances and a little less in others. In most cases the micro and optimisers cost a lot more so its rare in Australia that they are the best option due to subsidies being based on panel nominal wattage rather than total cost. In the US for example its different as the subsidy is a tax offset based on how much you spent rather than the combined panel wattage. It ceases to amaze me how many people just buy the most expensive system believing its the best. I can understand buying a car with a legendary brand name on display or beautiful furniture made from natural materials however for solar its up on the roof or a box outside so you really only see the output. You want something that runs reliably, quietly with great warranty and output. - I do agree with you on the 12.5A input issue. You need to let them know that they should release some new single phase models that have a larger amperage on the inputs. Ideally just do the same as the GoodWe MS series and have 3x MPPT that would mean you don't need to parallel inputs on one MPPT in the first place. That said I would think there are plenty of houses that can have say 2x strings of 11 panels (eg 350W Q Cells). That would be a nice setup for these inverters (1x 6kw model). They listened to you with the IV-Curve suggestion and I would love to see them with some L3 models that achieve mass market popularity (with the enhancements) as their quality construction and features are fantastic. - The REAL jewel in the crown for Huawei is their three phase models - They really throw down the gauntlet and have generous input parameters. The larger models also do away with the hybrid which is not really required as you point out. Further to this the latest M1/M2 models officially support the optimisers if you really need them. I would have to say however on a large system with good quality panels like the new G9+ you might not even worry about optimisers even if you have a little shading. The trackers on the Huawei are very good as per evidence in PVEL testing. If you had say three strings of 12 it would not really make a big difference if some panels were shaded early or late in the day as the production would be strong in the middle of the day. Panels are continuing to evolve with more bus-bars, third cut tech and bi-facial tech which again works well to address shading without resorting to optimiser's. Whilst a lot of houses don't have 3 phase in some cases its not expensive to upgrade. As an example it might be cheaper to upgrade to three phase and install a 13kw system with Huawei inverter than a single phase with 2x Single phase inverters or micros. That would of course depend on the string layout - eg 24x North and 12 West for example would work. If you did go three phase you avoid voltage rise and can export up to three times more power depending on the area you are in. You also point out that most of your installs are larger installs rather than the usual 6.6kw installs and thus this would be interesting. - Lastly thankyou for offering these products and reviewing them. A lot of your brethren gravitate to cheap and nasty products or overtly expensive ones rather than a sensible middle ground. I would challenge you to put these packages such as the three phase up on your website along with detailed information to determine if the consumer has three phase or not. Consumers are smarter than you think (although some are the opposite). For the single phase products you just need to again list them on your site and then give an example roof layout where it will work. The worst case scenario is you sell them a Fronius instead or perhaps a upgrade to three phase or two inverters if they don't have the right roof layout.
Nice video Mark... good information, great presentation... love the mic... good sound really matters. Yup... I love the partial deployment option for using the Huawei optimisers (deployed selectively on "problem" panels)... or using the Safety Box and full deployment. We've got a test system at the Lab... remove monitoring and support is great too.
i guess if you want to use optimisers, then this would be the best of the bunch? Steering well away from solaredge...I am getting a huawei setup installed with full optimisers (cos i'm geeky and also have 1 string which is going to get shading and another string which has multi orientation N+E). Plus the added advantage over enphase is that i am oversizing the 5kw inverter with 6.3kw of panels as i already have an older 5kw system on the main roof of the house and will be at my 10kw AC limit to the grid. Also i can add a DC battery later on (curious to see what huaweis battery pricing will be) which would not be possible if i went enphase and maxed out my 10kw AC limit.. eg : powerwall
@@mcelectrical Great video. I agree that the music level is too high - you could just fade the music level to a lower volume to push it more to the background.
I don't understand the problem with current you mention. I intend to use this inverter with flat roof and panels only in one direction. I understand that the EPS is only needed when there is no power in network, otherwise the attached battery will work as capacitor when network is running - so I dont have to push my production to network 100% of the time?
Absolutely! There really is no need for micro-inverters or optimisers as I showed in this video ruclips.net/video/TqOw43-hbjc/видео.htmlsi=gPlDmpXQ1xSjc0Ct
Love the presentation, very informative and straightforward. Please I personally need some education on the optimizer, My concern has to do with the output voltage of the Huawei optimizers. Am using a 275watts 10-50vdc rated optimizers on 275watts 38.9vmp panels but the output voltage of the optimizers has been reduced to 26.7vdc but I get up to 46.7voc when I test the voltages of the panels directly with a multi meter. Please is this normal ?
Thanks Mark for your commentary on Huawai Inverters but you didnt really talk much about the Huawai optimiser which was the stated intent of the video (unlike your excellent video review of Tigo optimisers). Frankly I was left a little disappointed: maybe you can do a part 2 specifically on the optimisers and their monitoring . Thank you.
Hmm, good point, I didn’t go into the optimiser much. But here is my update. Don’t use an optimiser. There is no need unless you have split orientations, and even then, it is better solved with good string design. Optimisers fail and don’t do much at all at best. If the issues is shade, use Fronius or SMA who have a quality gmppt (or “shade fix/ dynamic peak manager).
So these optimizers just push voltage/current until they reach the upper voltage limit? I’m looking for a solution to recharge 400v ev batteries, this seams like a very good option
Agree with Kim's comments. Personally installed and sold so many Huawei inverters and optis and believe that this is the best option out there for complex rooftops. But the message from this video is so confusing. Is it good or is it bad, or is the speaker confused as it doesn't align with what he promotes. It's definitely not cheap though, then why a dig on saying that it will go in the hand of cheap installers. Sometimes it seems technology advancements like Huawei's are well ahead of MC electrical's decade old mindset
at about $90 per optimiser, it is still way cheaper than an enphase system and still allows for up to a 30kw DC battery. As per mcelectrical website, a 10.8kw system using the same panels but a fronius inverter is $6000 cheaper than going full enphase. So going huawei inverter and full optimisers would save at least $3000 over enphase. I have noticed that the huawei 5kw L1 inverter states 600vdc for the battery connection. is this up from the 500vdc it used to be as per review www.mcelectrical.com.au/huawei-inverter-review/ ? One final thing, how does the new SA laws allowing remote disconnect affect the huawei inverter (remote disconnect compatible?) and the enphase systems...
Hi Vishal. There are good and bad parts about the Huawei. That's what i was pointing out in the review and in my blog. It has defiantly improved a lot since the original version but it think it still is wanting. It has it's place but it's a niche product - not good for the majority of systems we quote on. It is definitely cheap for a hybrid inverter.
I have the sun2000 6ktl -1l I have 6300 watts worth of panels and I have on string of 5 and on string of 9 panels will that hurt my total output power from my solar panels?
If you mean oversizing your panels, 300w bigger than your inverter, not at all. We normally install 33percent more panels, so 8kW on a 6kW inverter. This is usually better for inverter efficiency.
They will soon come out with a 9.9kw inverter that I’ll test. I’m friends with the guys from IStore so I’ll have to try not and be biased, but basically, I don’t mind Huawei. It’s no fronius and it is almost the same price. But their biggest issue was they didn’t have the range of inverters that I wanted to bring them on as a product.
We have been having trouble with the Huawei optimisers, they are cutting out multiple times per day. The system was set up on 2 strings 6 panels on one and 8 on the other (total 14*475w panels) 6.6kw. Huawei's solution was to put all 14 panels on a single string to increase the voltage and "force" the optimisers to work correctly. Does this sound normal?
Hi Simon, i can't speak for Huawei optimisers, but tigo and solaredge both have weird issues. I have completely gone off optimisers -stick with a string inverter with a GMPPT like fronius or SMA.
You're most welcome. If you're interested in a second opinion on the Huawei hybrid inverter have a read of this: www.solar4ever.com.au/HuaweiInverterReview.php P..S. I have a Fronius Primo at my place and also love everything about the new Fronius Gen24 Plus (except the price!)
Hi Yoni. APS didn't have a great start in Australia. I saw them at a trade show in China a few years ago and they said they are back in Australia. I havn't heard much since. TBH, I'd stick with Enphase who has a proven track record with a complex product.
Hi there! Can you do partial optimization in a single string? For example if I have 14 panels and I want to install 6 optimizers, can i do it within the same string or do i have to create a seperate string for the panels that use optimizers?
You can do partial optimisation. For the single phase L1 model its a minimum of four on a string and for the three phase models its a minimum of six (this comes from the datasheet) www.solar4ever.com.au/info/Optimisers.php Note that you can also use optimisers to run a string in several orientations or keep a string below 600v so they are quote versatile. For the multiple orentations you can do partial or full for the string. For example if you had six panels north and five east you could fit the optimisers to the east, north or all the panels on that string. if you fit it to all the panels it will work better as it can adjust both ways to match up but even if you do partial it will still alter output to match up with the unoptimised panels. Note that you need to keep in mind the minimums mentioned so if you had a string of ten north and three east then you cant just fit them to the east as that would not meet the minimum optimiser requirement so you could fit the ten north however in that case you may as well just fit them to all the panels in that string. If your other string is say 8 panels west then that can be left unoptimised to save money. Its a very versatile system and keep in mind you can always run 2x5kW inverters which will cascade for their data feed and act like a single 4x MPPT inverter in terms of monitoring and connectivity (only the first inverter connects to the smart meter and internet).
I don’t understand why you would not research before you do a video. The warranty on this item is 25 years! The 5kw inverter you say is no good for 90% of your clients because they install 9kw systems, well it’s 5kw per string! So 10 total. And you did not tells us what the actual power consumption of this unit is. So pretty useless video really.
Sorry about that Richard, but you obviously come from another country that has different warranties and different regulations. We can't 100 percent oversize a 5kW inverter.
By October 2021 - there are now multiple 3-Phase Huawei Inverters from 5kW to 12kW and even up to 20kW.
I have TIGO on SunPower modules with high voltage 60 to 70V - NO outage still 2015 !!!!

Please I personally need some education on the optimizer,

There is no need unless you have split orientations, and even then, it is better solved with good string design. Optimisers fail and don’t do much at all at best. If the issues is shade, use Fronius or SMA who have a quality gmppt (or “shade fix/ dynamic peak manager).
So these optimizers just push voltage/current until they reach the upper voltage limit? I’m looking for a solution to recharge 400v ev batteries, this seams like a very good option
Agree with Kim's comments.
Personally installed and sold so many Huawei inverters and optis and believe that this is the best option out there for complex rooftops.
But the message from this video is so confusing. Is it good or is it bad, or is the speaker confused as it doesn't align with what he promotes.
It's definitely not cheap though, then why a dig on saying that it will go in the hand of cheap installers.
Sometimes it seems technology advancements like Huawei's are well ahead of MC electrical's decade old mindset
at about $90 per optimiser, it is still way cheaper than an enphase system and still allows for up to a 30kw DC battery. As per mcelectrical website, a 10.8kw system using the same panels but a fronius inverter is $6000 cheaper than going full enphase. So going huawei inverter and full optimisers would save at least $3000 over enphase. I have noticed that the huawei 5kw L1 inverter states 600vdc for the battery connection. is this up from the 500vdc it used to be as per review www.mcelectrical.com.au/huawei-inverter-review/ ? One final thing, how does the new SA laws allowing remote disconnect affect the huawei inverter (remote disconnect compatible?) and the enphase systems...
Hi Vishal. There are good and bad parts about the Huawei. That's what i was pointing out in the review and in my blog. It has defiantly improved a lot since the original version but it think it still is wanting. It has it's place but it's a niche product - not good for the majority of systems we quote on. It is definitely cheap for a hybrid inverter.
Im trying to use the sun2000-450p with another inverter but its not working, will the gateway turn them on?
Which 60 or 72 cell solar panel works best with Optimizers for charging a 24v battery bank
I have the sun2000 6ktl -1l I have 6300 watts worth of panels and I have on string of 5 and on string of 9 panels will that hurt my total output power from my solar panels?
If you mean oversizing your panels, 300w bigger than your inverter, not at all. We normally install 33percent more panels, so 8kW on a 6kW inverter. This is usually better for inverter efficiency.
Any thoughts on istore rebrand?
They will soon come out with a 9.9kw inverter that I’ll test. I’m friends with the guys from IStore so I’ll have to try not and be biased, but basically, I don’t mind Huawei. It’s no fronius and it is almost the same price. But their biggest issue was they didn’t have the range of inverters that I wanted to bring them on as a product.
We have been having trouble with the Huawei optimisers, they are cutting out multiple times per day. The system was set up on 2 strings 6 panels on one and 8 on the other (total 14*475w panels) 6.6kw. Huawei's solution was to put all 14 panels on a single string to increase the voltage and "force" the optimisers to work correctly. Does this sound normal?
Hi Simon, i can't speak for Huawei optimisers, but tigo and solaredge both have weird issues. I have completely gone off optimisers -stick with a string inverter with a GMPPT like fronius or SMA.
can you install this inverter without installing the optimizers?
Yes.
Yeh, the optimisers are just an add on.
@@mcelectrical thank you for your reply 🙏
@@wmfoster thank you!
You're most welcome.
If you're interested in a second opinion on the Huawei hybrid inverter have a read of this: www.solar4ever.com.au/HuaweiInverterReview.php
P..S. I have a Fronius Primo at my place and also love everything about the new Fronius Gen24 Plus (except the price!)
Thanks for your great videos and informative reviews
Appreciate if you could give your thoughts on APSYSTEMS microinverters as well
Hi Yoni. APS didn't have a great start in Australia. I saw them at a trade show in China a few years ago and they said they are back in Australia. I havn't heard much since. TBH, I'd stick with Enphase who has a proven track record with a complex product.
@@mcelectrical thanks
Appreciate your response
Hi there! Can you do partial optimization in a single string? For example if I have 14 panels and I want to install 6 optimizers, can i do it within the same string or do i have to create a seperate string for the panels that use optimizers?
You can do partial optimisation. For the single phase L1 model its a minimum of four on a string and for the three phase models its a minimum of six (this comes from the datasheet) www.solar4ever.com.au/info/Optimisers.php Note that you can also use optimisers to run a string in several orientations or keep a string below 600v so they are quote versatile. For the multiple orentations you can do partial or full for the string. For example if you had six panels north and five east you could fit the optimisers to the east, north or all the panels on that string. if you fit it to all the panels it will work better as it can adjust both ways to match up but even if you do partial it will still alter output to match up with the unoptimised panels. Note that you need to keep in mind the minimums mentioned so if you had a string of ten north and three east then you cant just fit them to the east as that would not meet the minimum optimiser requirement so you could fit the ten north however in that case you may as well just fit them to all the panels in that string. If your other string is say 8 panels west then that can be left unoptimised to save money. Its a very versatile system and keep in mind you can always run 2x5kW inverters which will cascade for their data feed and act like a single 4x MPPT inverter in terms of monitoring and connectivity (only the first inverter connects to the smart meter and internet).
information starts at 3:49 thank me later
Ha thanks Giorgi. Sorry about the rambling. I'll start doing time stamps if you want to cut to the chase.
You should probably update this g
Ha yeh, I probably should get a new Huawei inverter and test it.
I don’t understand why you would not research before you do a video. The warranty on this item is 25 years! The 5kw inverter you say is no good for 90% of your clients because they install 9kw systems, well it’s 5kw per string! So 10 total. And you did not tells us what the actual power consumption of this unit is. So pretty useless video really.
Sorry about that Richard, but you obviously come from another country that has different warranties and different regulations. We can't 100 percent oversize a 5kW inverter.
Had to give up. Three mins in and zero info on the part. Need to concentrate on the product.
Do not buy anything Chinese
I agree with the sentiment but that makes life a little difficult.
