I’ve been designing/contracting residential PV for 17 years and I’ve installed thousands of both Enphase and SolarEdge inverters. We basically stopped recommending SE years ago because their failure rate is simply unacceptable. SE’s RMA process also is less than adequate. They make a great product when it’s working but the last thing any solar contractors wants is thousands of installed systems under warranty that are prone to failure; case in point is Pink Solar who just went BK as a direct result of what I’m describing above (not SolarEdge related though). If you’re a homeowner and you’re in the market for a 12kw or smaller system then it’s worth it to spend a little more and get Enphase. That’s my opinion. When you start getting into the larger systems like +30kw then SE might start to make a little more sense

Also any other voltages than 240 or 208 is difficult to install with Enphase, so that’s a slight bonus for SolarEdge if you’re installing a solar system on a building with 277/480 voltages.

Joe, another great video. I am about to have an Enphase system installed in Australia. Enphase will only provide a 15 year warranty on the micro inverters rather than the northern hemisphere 25 year. Maybecthey are concerned about long term heat affects. I chose micro inverters for the redundancy aspect, although my only concern was, what if Enphase closed, where would a replacement micro-inverter come from?

Hey joe, I have been meaning to talk with you about your use of the term Daisy chain wiring to describe series wiring. It is a great sound bite, but it is wrong. Daisy chain wiring describes parallel wire common ground and common hot along the string. In Printed circuit design low speed circuits can be star or Tee wired. To control the trace (wire) impedance high speed circuits use daisy chain routing this reduces the refections of the trace. A better analogy would be series strings are like the very old Xmas tree lights that when one lamp fails the whole string fails versus newer Xmas tree lights that are wired in parallel so that when one light fails the rest of the lights stay on. In summary string inverters are basically series strings ( optimizers bypass the failed or poor performing panel). Micro inverters are true parallel circuits. Mixing and matching solar panels with Micro inverters is not a problem. Mixing and matching panels with a series circuit and optimizers provides no benefit. Before I go, what is missing from the current solar ecosystem is a vendor agnostic balance of system. If I choose a Tesla Powerwall I am locked into their gateway, their switch….This is true of every vendor in the market. There are some bleeding edge solutions in the DYI market, but nothing that I can get permitted or approved in my market here in San Mateo County CA. I have enphase Micro inverters and 2 tesla powerwalls, Tesla doesn’t give me a generator option Enphase does. Neither provides a solution that allows me to cross upgrade or maintain my current system. There are no barriers to entry just the need for existing players to produce battery, inverter and solar agnostic balance of system hardware *this includes incoming grid service panels. It is ridiculous that we have to upgrade the service panel to handle loads that it will never see. I send people your way almost everyday. Keep up the good work. Thanks for all you do.

Joe, I gotta give you some critiques on this video. First of all, I’ve installed SolarEdge systems and Enphase systems for almost half a decade now and I’d say that the failure rate for the SetApp SolarEdge inverters is still around 30-40%, especially around year 5 of the install. This failure rate is still unacceptably high and I believe it has to do with a few design flaws with the SolarEdge central inverters. It’s also highly annoying as an installer to have to drop everything on a service call when a customer’s entire system goes down because of a central inverter when replacing a single microinverter take only around 15-30 minutes tops and it’s only one panel down in the entire system. Also, Enphase has a powerful 384 VA IQ8 H microinverter for 240v systems but obviously that microinverter is going to be very expensive in a quote. I would say one of the main advantages of SolarEdge is still for commercial installations, because Enphase doesn’t have a very easy to install solution for 277/480 buildings besides to add in a step-down transformer which can be annoying to have to install. Because most high powered modules are still around the 400w stc level, the clipping losses are pretty insignificant especially when paired with an IQ 8H inverter. That said there is a tiny round trip efficiency boost with SolarEdge because of the DC to DC conversion, but it’s not really enough in my opinion to justify having to deal with the single point of failure problem which can be extremely frustrating and annoying to deal with on service calls.

Warning… I’m going to be controversial on this I’m sure… First- Joe, your last video comparing these products was good and when I saw this one, I thought it was that previous video, but I clicked anyway and I’m glad I did. I very much liked this one. Second- my opinion based off my experience is, we way too easily accept the idea and the studies that say clipping loss is actually good, helpful in some locations or acceptable. I have not read many many studies and claim to be anything close to an expert on the methodology of these studies, however it causes me to wonder who is most set to benefit from this type of finding? Maybe Micro inverter manufactures? I’m sure this is a terrible example but I don’t want to spend my hard earned money on a home air conditioner that’s capable of cooling my whole home, but then my electrician only provides enough electrical power to use part of the cooling capacity and call it clipping and tell me it’s acceptable or good for me…I want my system capable of running full capacity. I struggle that it seems we say, oh well that’s just clipping loss and accept it. It seems we then tend to encourage Home Owners to accept it also. I know some higher VA Micros are coming or are in the works, yet this not the whole of my comment, but I’m speaking to the mental acceptance over the last many years. I offer this possible other questioning attitude…Instead of simply accepting this mindset as many have up to this point, why don’t we collectively demand higher VA from Enphase or other manufacture? Our dollars are powerful! Especially when see modules are capable of producing between STC and NMOT, And we know the module industry is consistently showing increased module wattage year over year it seems. I realize there are pros and cons for increased VA Output of micros, yet for the purposes that often times we are trying to harness as much light energy to convert to electrical energy as possible per given amount of space, For me, I want higher VA Micros that the common customer can reasonably afford. Ok, I’m done. Lol Thank you Joe! You run a great program!!

DC coupling is a superior architecture, especially when storage is added to a system. Adding a battery to a SolarEdge system eliminates any downsides of clipping. The single point of failure is still there, but the inverter can be serviced from the ground without going on the roof. I've found the optimizers to be extremely resilient and provide the benefits of micros at a much more acceptable cost.

@MrDontcareify

Жыл бұрын

I definitely understand the issue with micro-inverters clipping. But with 384 VA micros and 400 watt panels, very few NMOT conditions will even produce 400 DC watts of power from a solar panel. That said, clipping is still an efficiency loss, even if it can be small. One of the annoying aspects of Enphase is also the tighter tolerances on voltage drop/voltage rise, which isn’t always mentioned. Enphase systems only allow 2% for the entire system, which SolarEdge is close to 4%. So field wiring costs can sometimes be more expensive for Enphase depending on distance of the solar system to POI.

Enphase for the win! Thats what we have.

Ive had 12 enphase solar pannels installed on my roof with seperate micro inverters and its working brilliantly BUT im trying to get a price for a powerwall but when i asked enphase through the contact us link and they wont give me a price they keep telling me to contact my installer, surely installing an enphase battery energy storage powerwall cant honestly require an enphase tradesman to install the powerwall?....can it !?, or can someone on here tell me how much a powerwall will cost me and tell me jow easy or difficult installjng an enphase powerwall will cost me?.

I have both systems installed on my house. South side has Enphase. The installer was terrible and the support from chat and voice both equally useless.

Even after 3 inspections, the ONE thing they should have done, but didn't, was to make sure it turns on. It did not. Took another 16 days to get a tech out. Both systems combined is 8kw. Had I to do this again I would max out the entire roof, tariffs be damned. The monitoring software doesn't understand there are two systems. Basically have to trust NVEnergy to not do me dirty.

Super easy rma US based support I cannot stress this enough how important this is.

Enphase is they unbeaten leader!

Enphase's combiner box has an 11 panel limit per line to roof, not "13 or 14" as you describe. I don't understand what happens on the roof but my understanding is that they plug into the line in parallel. So our 21 panel system only has 2 lines going to the roof. However; one advantage to getting DC from the roof (unlike AC from MicroInverters) is that battery storage & use can all be done before conversion loss, and before the power company can complain about exceeding limits (as with California's NEM rules) - potentially a major factor for future expansions that include a battery. With AC, it has to re-convert to DC for battery, then back to AC to be used or re-sold back to Edison. Do I have this right? Finally; life-expectancy is a major factor. Historically I've heard that central inverters last about 10 years, but micro-inverters should go for 25 or more. That's a HUGE difference that most reviews gloss past. I'd be interested to learn if that's been improved on.

Hello, I live in central Pennsylvania. I am working with a solar contractor that utilizes Enphase inverters. He is specifying the iQ8+ inverter for a 38 panel system with REC 405 pure panels. I was looking at the output of the panel compared to the continuous power input for the iQ8+ and it looks to me like the panel put out more than the inverter can handle continuously. I asked if they thought I would be better off with the iQ8a which looks to exceed what the panel can put out. I was told that the iQ8a isn’t as good with low light power as the iQ8+ and that because I live in the north east the iQ8+ would not likely clip or have the panel exceed the inverter.

I am surprised that you completely ignored the need for a DC buss and DC rated “fusing”. At least in my area the cost to build out an approvable DC system to the string inverter, eats up any cost advantage of the optimizers. I chose Micro-inverters for my install because it is the cleanest solution. No DC buss, built in redundancy, and the ability to mix and match solar panels of differing output, size and manufacturer. LG has exited the solar panel business, If and when one of my 39 LG panels fails it is a no brained to replace it with another panel from a different manufacturer and different performance. This is not the case with a string inverter with or without optimizers. I get it that in the trades the lower bid almost always wins, but who wants a solar system that is obsolete the day it gets installed. Overcapacity on the Micro inverters is a feature not a bug. I have worked as a EE for a long time an reliable systems always have head room designed in. Enphase is delivering mature products that’s just work. A DC system is not simpler to install or permit. I have nothing against optimizers, I just can’t for the life of me come up with a scenario where I would rather have then on my system. I appreciate all that you are doing.

Here in Puerto Rico beside the experience with hurricane we have a BIG problem with the ELECTRIC company GRID its a old system and problematic along with the management that operate the company so long story short I had a SolarEdge system with 24 solar panels and the inverter use was 76000 serie inverter the big monster elephant in the room that has to operate with a small transformer on the side do to the batteries that I was using the Powerwall first generation (6.4km) 2 of them and that system was giving me all kind of problems, probably the batterie incompatibility wrong setup or connection you name it but the main issue that I found was that during of grid mode the combine energy consumed from the inverter and transformer to operate and maintain my hose was using a lot of energy from the batteries so with this new system that I have same 24 panel iQ7 and one Tesla Powerwall 2 battery its a big difference that battery it last me all night and morning till sun come up. I will never ever use a Solar Edge product again not event a BOLT or NUT made from solar edge

I installed panels last year (2022) and was fully aware of 2:52 - shade will bring down entire string to lowest efficiency. I read this in all the places I learned about solar panels. So I bought 3 optimizers to see what is the difference between panels with optimizers and without. But to my surprise, in real world, I don't need optimizers. The shade drops either on optimized panel or not, it doesn't bring my whole string down. Where do I read about WHY that happens? I have Growatt MOD 9000TL3-X inverter and Jasolar JAM54S30-405/MR panels. 'm aware that panels have bypass diodes, but I'v been thinking there are physics into play that prevent specific amount of current going through shaded panel, etc, etc... so where do I learn about what part of the system enables a simple string inverter to behave pretty good in partially shaded env? I guess maybe panel gets "shutdown"/bypassed instead of getting any shaded juice out of the panel in my case, but I have to experiment a bit more to find out.

The problem with the microinverters is that you have to convert twice to store in DC batteries whether they are station batteries or EV battlers. The EV will be one your largest consumers of power so shouldn’t you be geared towards that demand? I don’t think microinverters will have as much draw as we move into more home batteries and V2H / V2G configurations. Too much power lost converting. Besides replacing a string inverter every 10 to 15 years ushers in new functionality and maybe even more efficient dc-to-ac conversion.

Still not enough for Panel 470w and above

Very few residential customers install 470 watt panels. They don’t fit on a roof in a 60 cell format.

You seem to be forgetting APsystems

Please, when speaking about string inverters stay with the current panel technology, not old, with multiple diodes, split cell, and much improved inverter MPPT that works extremely well. Much research has proven that the past shade advantages of micro inverters and optimizers is in the past. Also, failure rate of solar panels is 5 in 10,000! Yes, .05%. Think about this, Solar Panel warranties are 12-30 years because of the reliability. Thus monitoring each solar panel is unnecessary. Regarding SE and Enphase, get Enphase.

I don't like the screenless solar edge. Tying up my phone is not a good thing especially for about 25 minutes

SolarEdge just sent an E-mail allerting users will loose the ability to remotely monitor their systems. They said, T-mobile cancelled service for the network. I can purchase a new modem. What terrible customer service. Six or Seven years into a 25 year warranty. Shop around and find a better company.

TL;DR Enphase advantages the home owner. SolarEdge advantages the installer. In my area, Im kinda sick of installers pitching and pitching and pitching SolarEdge and downplaying Enphase, ironically saying "microinverters fail more often" (ummmm... I asked you about your experience with Enphase).

3 Gen IQ battery shipping now features the IQ8HP, and 4 Gen battery will feature IQ9 with GaN before the end of 2023 in the USA . IQ9 with GaN for PV in early 2024 sign up for beta

😊 Found you Slem.

A lot of good info, too bad Joe didn't cover the operating temp limitations of Enphase and speak about the warmer climates of the South. 60 deg C and our rooftops in Las Vegas can exceed 170 deg F. MAJOR CLIPPING!!!!!!

I think the information on DC to AC ratio in this video is overly simplistic. There's a lot more that goes into it. In areas of high heat, like Florida, you can get away with a much higher ratio without significant clipping. Enphase has done an extensive white paper on the subject showing module pairing scenarios in different climates.

i read a lot of solar edge failures

Would you rather have an ultra reliable PV array connected to an easily serviced string inverter and not see individual panel failures or. hard to service under array electronics operating in a hostile environment that gives visibility of panel failures? Why compromise the reliability of your array with under array electronics? Hard to service

? I had an optimizer go bad when my system was five years old and I changed it out myself with a used p320 optimizer off ebay for $30. Took less than 30 min and that was 3 years ago.

It is more efficient to convert 240 VDC to 240 VAC than to convert 12 VDC to 240 VAC. But it is easier to ship AC over wire for distance than it is to ship DC. So maybe we should get DC optimizers and string inverters on the roof, then combine the outputs of the different string inverters to send down to your panel.

Enphase is like IPhone and Solar Edge is like android.

Or can you build your own powerwall for a cheaper price than what enphase will charge me?

Off course but itell be a Frankenwall.

Geeze, the SolarEdge website is a convoluted mess with respect to researching their systems.

Problem: IQ8 is a no see in Europe - so it's an easy choice Additionally with panel at/over 470w Enphase inverters aren't powerful enough - I know it'll work but the discrepancy gets too much

IQ8 will be in Europe from Q1 2023.

Seems everyone is jumping ship on SolarEdge. Their reliability continues to be a complete disappointment.

Enphase is trash in Arizona. Don’t do it

@@maximus20895 simple put, you know how your phone has those heat warnings? And you know how when you charge your phone it gets really hot? So that’s a micro inverter converting ac to dc. Enphase is doing that on your roof under every panel. So when it’s 110-120 out your roof is about 30-40 degrees hotter. Now imagine a cellphone on the roof charging for every panel you have. It ain’t reliable. And oh by the way any contract you sign the installer won’t service 1 micro they wait for about 5-7

Neither! Go a simpler string inverter

SolarEdge is junk.

Why do you keep talking about shading on string inverters when there are many videos online just proving that they put lots of shades on those string inverter panels and it has very little effect so that advantage now has become moot, and probably because of the multi cell configurations within the solar panelwhat’s your response to the new stuff? This info is a little outdated now.
