- This video explains the technical differences between SolarEdge and Enphase so that you can make an appropriate purchasing decision.
I'm not involved in solar anymore but if you'd like, but I'm happy to do consultations for $60 for a 30min call. I can review solar installer proposals and give unbiased professional guidance, design/spec out custom solar projects (non-home installations), or give direction or answer any questions you may have.

Alternatively, my mentor in Denver is still involved in solar and can provide proposals. If you'd like to get a proposal from him you can reach out to him directly at his website www.solar4planeta.com/
He is based in Denver but has access to a network of installers around the country. Good guy. I will be getting my solar through him someday when I purchase a home.
Theyre both great folks. Pick whichever fits your preferences.
Very good explanation, very simple for homeowners to understand.
Ooof. So nice to have the impression that the video presenter on this complex and divisive topic lacks bias, a perceived relationship to a product, or unquestionable certainty. So thank you. I'm still in the shadows with installer suggestions on offer though. Bit your vid is helping in the right direction .
About pricing now (speaking about the Inverters)... I'm doing a lot of DD on Freelancer Finance channel...
From all my research Solaredge is maybe $500-$1k less... for a system that costs 30-60k... and will last 25 years...
it's a no brainer to use Enphase and not worry about a central inverter failing even for a day (if not for months).
Good video and fortunately I have both an Enphase solar system of 10Kw and a SolarEdge one of 5Kw. I like them both, but I prefer the Enphase one where I get maximum wattage due to the IQ8-H microinverters.
Enjoyed your video - thank you. I am looking at a future home DIY 48V battery backup system, and have a partially shaded property that could greatly benefit from micro-inverters or optimizers. I've only heard rumours but, is there an off-grid micro-inverter or optimizer system available? Would very much appreciate your input. Thanks so much.
SolarEdge "99% efficiency" claim is misleading. DC optimizers (upstream from the inverter) have ~2% loss each, which conveniently gets ignored in the marketing material.
Optimisers have 0.5% dc to dc conversion loss, not 2%. Even with that, the benefits of fixing the voltage on the roof so it hits the inverter sweet spot all day means you will always see more efficiency from solaredge than any other tech. Micros are just like string inverters, only tiny. No dc control, still subject to finding efficiency in their band of operation.
Do you need optimizer? I don’t think so while en phase you need it
@@brentthesolarguy Heads up this is the main salesman for solaredge in australia. His company is going insolvant because of the mainstream adoption of the bypass diode. More like solaredgecase
The rectifier comment is partially true though it may be simpler to state that their Inverters are Bi-directional as the Microinverters in the batteries are bi-directional. Also there are 6 inverters per 5kwh battery so redundancy is x6 for the same amount of stored energy. If one X-BAT inverter fails the homeowner still has access to all the storage.
In this case the Battery fills the low production gaps of the Solar if a cloud passes over.
Enphase allows PCS controls so you can put 30-40Kw on a roof when the Main Panel or utility limits you to 7.68kw the way Enphase does it is far superior because if you connect a car to charge it the system will release all the power and yet limit what only goes to the grid.
hey sorrosh thanks for the explanation very helpful and in depth. how do you size the solar edge inverter size according to panel size (ie. 4kw 10 400w panels)
thx
Glad you liked the video! And good question, this would make a good standalone video on its own. I'll do my best to simplify oversizing a SolarEdge Inverter to a few sentences. For a 4kW sized system, you'd either spec a 3kW or 3.8kW SolarEdge Inverter. Which you choose depends on environmental factors such as ambient temperatures, panel orientations, expected real-world outputs from the panels, and customer goals. As a general rule (in my opinion) you want to aim for 10% - 30% oversizing. Basically, you want to load the inverter up such that it is producing the maximum amount of power that it can handle without producing significant clipping/power losses during the peak production hours during peak production days in the year. Hope this helps!
A kilowatt is 1,000 Watts
Another thing most people miss is that just because you are charging batteries from DC in the case of Solaredge, does not mean there is no energy conversion taking place. An optimizer is called a DC to DC converter for a reason. Another DC to DC conversion also happens when charging the battery from solar. Thus it is not accurate to say there are no loses in a DC coupled system. And after 9.5 years in the PV industry, with more than 2000 sites on our fleet and multiple NABCEP certifications, I'd always pick Enphase over Solaredge any day of the week and twice on Sundays.
Nice vid but need to update for Enphase IQ8 please
great video, but why didn't you use the data sheet for IQ8 models?
Good question. No particular reason - honestly I just pulled the spec sheet from a folder on my computer where I keep a bunch of datasheets and I guess I never downloaded the IQ8 datasheet when it came out. The CEC weighted efficiency is still 97% on the IQ8s though so it doesn't make much of a difference in the context of what I was talking about. I'll make sure I'm using the newest versioned datasheets on my next video though! Thank you!
Iq8 output is 360w, iq7a is 366w, so hes being kind by showcasing their previous, better micro, lol
For Enphase you would just need to add another circuit. It's designed this way to increase safety and longevity.
At this point these are about the same as far as comparisons. The other nuance is the amount of copper wire and gauge required for long DC runs.
I’ve had my 10.5 kw solar system with SolarEdge inverter system for three years. On the anniversary of the system the inverter died. It was down for a month with free replacement. Luckily it didn’t affect the yearly production, that bad. We have been ahead of this grid game with SCE, so far. We produce more KWH than we use, but they charge us .30/kwh used, and they give us .09/kwh that we send back to them. I’ve heard it’s going to get worse. That is why I am starting my investigation into battery storage for this SolarEdge system. Except for the house AC, we can disconnect Edison and live off grid. I just don’t know how much battery I need. Any formulas or charts I’m going to need to figure this out??
Why did you leave Sunbright?
I don't think your point on if one panel in a string is shaded, the rest are brought down is true, at least not anymore. Several hands-on videos out there that debunk this, at least with modern panels. Doesn't mean there aren't other issues but I see far too many pushing this point when it's not true.
Modern panels use bypass diodes and other internal circuitry to prevent partial shading of a panel from lowering the output of the rest of that panel, however, you still need either a DC optimizer or a microinverter to solve this on the string level so that all panels in the string don't lower their output to the lowest performing panel. Cheers my friend
If you a homeowner don’t buy SolarEdge I did 3 replacements for 1 home within a month because it was refurbished equipment
There is no way to compare a central inverter with micro inverters. This is the moment when people needs to understand that for a non significantly difference of money they are able to get a micro inverter system. I don’t wanna explain the reasons, there is too many information about this but definitely, it’s no brainer decision to move forward with a mirror inverters, also, if you move with SunPower, the company I work with, I will show you why it’s not just about inverters, but the choice of the panels, and also the important consideration in efficiency terms and quality of materials. As I said, anyways, I highly suggest to move with a micro inverter system instead.
You made a huge mistake by compared them. Both companies doing a very BS job.
enphase battery fucking expensive against SolarEdge Batterys what you can build up
I have to assume it's because Enphase batteries require additional rectification and inverters inside of them since they are AC-coupled. I'd imagine this is one of the big contributors to the price
Realy bad video! Panels these days are pritty good... - a diode and solarpanel compare.... 😂 - if you do not have a lot of shade - just put them in a string... micros are just costly and do not add value all the time! The big fields don use these... they never break! Micros warrenty sucks...
