Thanks for the info. Im in the process of going solar with a 24.7 KW system and I'm going with Enphase and one 10Kw battery and 61 REC 405 panels for that very reason they seem to integrate so seamless, I plan to add more batteries in the future but I also like the fact that the system creates a micro grid and becomes self contain when the power goes out so you have power during the day even when must other system shut their panels, great feature.
Congratulations - may I ask how much you are paying for your system. Email might be easier - jon@mysolarhome.us - it will be a good validation that you are not over paying. Let me know your location too since prices vary by region. Best of Luck
I would not go with Enphase for such a large system. You can do much cheaper and better with other components, Enphase batteries top out at 40 kWh which is half the residential limit by fire and national electrical codes. It’s extremely overpriced per kWh due to the complexity and need of DC to AC to DC inverters for every 3 kWh battery pack. You’re buying into their infrastructure for every component and you can only keep using their product and their monopolistic prices.
@@MySolarHomeUSA here you gone Jon 75899.00 for the panels inverters and 14500.00 for the first battery, 15 year finance at 5.74% ) 0 down plus I'm getting my roof done too extra of course but it all qualifies for the 26% tax benefit. no brainier for me I know there are always better cheaper options out there for some, but after I did my own research this one made sense to me. If I keep researching and calculating nothing will get done cause there always is a better deal to be had some where else. thanks for the reply nice to read the difference of opinions.
@@cluna5231 That is extremely expensive. Like extremely expensive. I think your installer is paying roughly around $36,000(cheap panels) to $38,000(good panels) for the panels and inverters and the connectors and cables. You are paying 111% of the cost on labour. Which as i said is extremely expensive.
Am hoping Enphase bundles the 5P as a three-pack as they did in the 10T. A 15T with the better continuous and surge power of the fives would make the 15T a powerhouse. One might even fully support a "whole house" system if used carefully.
Have you heard anything about new batteries coming out this year/ 2024? Do you think if I got a system with IQ8’s do you expect them to play nice with a new battery system in next year or 2?
What is likely to happen is that battery prices will come down in a couple of years. And yes they will definitely be compatible with the IQ8's. If you are planning to go solar, do write me at jon@mysolarhome.us and I could help with a quote. Thanks for watching
Why does enphase limit the amount of panels that can be plugged into the battary. say if there were 8 strings but they only allow 6 to be plugged in? Is this because the enphase micro inverters?
That is to limit the amount of current that flows into the battery from the solar panels. Beyond a certain no of strings, the total current would overwhelm the battery and cause damage. Hence they limit the no solar panels. Thanks for watching.
@MySolarHome thats a great point. But wouldn't the software and whole enphase communication app load balance thing be able to prevent that if you're using enphase micro inverters as well? Thanks for answering:)
@@billionairefaith1 Yes - everything will be controlled by the IQ controller. So having a larger system is not a problem. Let me know if you are looking for a quote jon@mysolarhome.us Thanks
Fifteen years ago I had a Fronius system installed. We'll leave that alone for now. Then I had a 6.7 kW SE system installed without battery two years ago. At that time they were using LG batteries but now they have their own, but that has been on the market for only a year. The Solar Edge system would not let me control its operation. I had to call my installer to change parameters and getting SE customer service was a nightmare. It worked fine otherwise, but I wanted more control. The Enphase University lets you become a owner instller which allows you to get deep into the operation of the system through the Toolkit. I liked that. So I switched my optimizers for IQ7+ and moved the optimizers onto some of the Fronius panels. Now I run the 6.7 kW array as microinverted panels and I run the SE inverter on the optimized ex-Fronius panels. I'm able to run that new 3kW SE system through the Enphase combiner box. Now I can fill my battery storage from a 10kW array. I actually installed two IQ10 batteries. The Enphase system even creates a microgrid that allows the SE 7600 to operate in a grid down system. I guess the SE battery would do the same in a grid down system. I believe I am correct that four Enphase batteries would have an additive power of 14.2 kW (3.6 x 4) If you put two SE 7600 together in a master/slave setup with multiple batteries you would still only be able to pull 7.6 kW. I haven't priced the other batteries in particular the SE. It's probably cheaper as one fellow said, but we don't yet know it's build quality. The Enphase batteries are bulletproof (figuratively and maybe literally). I don't even think we can get Tesla batteries in CA right now unless you put on a Tesla roof and I've heard the customer support is less than stelar. The Enphase support is fabulous. Then lets talk about the "fabulous" SE EV charger. I have a Tesla Y and my charger is wired right off my critical loads sub panel with a shut off solanoid to disconnect it from the panel in the event of an outage when EV charging is taking place. That solanoid is operated by the Encharge unit. You wouldn't want to drain your battery into your EV during an outage. I assume the SE EV charger is that smart too. Then I have a Kolher generator that turns on automatically if needed (again via the Encharge). If is was a cloudy day and PV was not serving my loads and the battery was going to be drained, the generator, battery and PV could serve my loads. I could even have them all charge my Tesla during the "Big One". BTW portable generators cannot be used to my knowledge in the Enphase system. Where is SE in the generator business? I'm just a homeowner not an engineer, so I defer to others but I'm convinced that Enphase is the way to go. Apparently the stock market thinks so too by its valuations and a number of our local installers are switching over and are now able to offer Enphase and SE. Does the SE system have automatic battery fill from the grid in the event of a potential grid shutdown for weather or fire.?The Enphase system notifies me and starts charging my batteries to full capacity. It has happened about six times in the last year. It was nice to have a full battery prior to the grid shutdown. That's it for now. Thanks
Thank you for that very detailed comment - it deserves its own webpage. Excellent information. It is always good to hear from a practitioner and see an actual application. Super of you to share your experience and knowledge. Thanks again and thanks for watching too.
I have Sunpower PV system with 5.7Kw(Max) capacity. i'm looking to add more panels and add battery this round. Do you know if Enphase is still good option to mix existing PV o/p to the battery or GRID?
Yes you can add more panels - it will be a second solar system and you can add Enphase batteries as well. Email me your requirement jon@mysolarhome.us - I might be able to help with a quote if you know how many panels you wanted to add.
Can a portable inverter generator be hooked up to the enphase bidirectional charger to back feed power to charge up my enphase solar batteries. I’m trying to find a solution other than the enphase schematics for emergency charge of batteries as that is not something I feel comfortable doing. Please advise.
Enphase Bi-directional charging will require the IQ controller - that is expensive. And that ony works with the IQ8+ micro inverters and their own batteries that also come with IQ8+ micro-inverters. They are not very DIY friendly. I would look at other solutions.
I have just added 13KWH of Enphase batteries and the system works very seamlessly. I notice that the system now uses about 2KWH/day maintaining the batteries and this seems like too much power drain. I am unable to get a good answer from anyone at Enphase. I would really like to hear from othe users if their enphase batteries use this much power from their power company each day.
Hi Don, Thanks for watching and commenting. I agree the 2kwh a day to charge the batteries seems excessive. It looks like your home may be using battery power for some of your usage and then getting replenished. There may be a mode in the Enphase battery which could be changed to stop it from powering your home during non outage hours. Best of Luck.
@@MySolarHomeUSA I have looked at other Enphase battery system and it look like it is the Microgrid system that requires the extra power to maintain. I have found that whatever power is used from the batteries to avoid peak power charges, it takes about 1.9KWH more to charge the battery back to full. If the battery is just set to remain full the system uses 1.9kwh / day to just maintain the system operation. It would be nice to know if other providers battery systems have this same system overhead power requirement.
You forgot to add that only your installers have access to install soft ware . I want to install micro invert system I bought second hand enphase installer refused only interested in new install (more money )so regular installer could not install. same with battery bought second hand charged to check and install it has never worked properly enphase not interested . If you purchase this system you are at the mercy of enphase . Not surge protected as my battery burnt out after power surge. 2 yrs after install
I am sorry to hear you are having problems. Unfortunately, this is true for everything in our country - you only get a warranty if you buy new stuff. Best of Luck.
I’m going to continue disagree with you on Enphase being the best system. You’re doubling the inverters compared to a hybrid string inverter with optimizers, you do AC to DC to AC conversion every time you charge and discharge the batteries and this system costs a fortune when compared to other solutions. A “large enough” single inverter is far cheaper than 50+ micro inverter. Scalability on micro inverter systems is simply not viable, period.
It is nice to see opposing opinions, I appreciate it. I base my opinions on working with over a 1000 solar systems using Enphase. The 25 year warranty and super fast RMA service make them my favorite. Also the price differential is actually not there - unless you are comparing with smaller battery vendors. Solar Edge, Tesla, Generac and Enphase are all priced very similarly - unless some Enphase dealer is trying to make a killing. The central inverters have a normal warranty to 12 years - the extended warranty is based on adding a price for a midlife replacement. With 50 optimizers and perhaps 2 or 3 inverters, a complete DC based system - you have more points of failure. In terms of performance difference it is marginal less than 2 percentage points in the round trip - so I will still stick to Enphase being the slightly better options overall.
@@MySolarHomeUSA Enphase round-trip efficiency is 89%. As an example, Sol-Ark's efficiency is 93%. That is hardly "less than 2 percentage points", it's actually more than double that. Regarding warranty, the 25 year product warranty from a reputable manufacturer such as Enphase is definitely nice. The problem is labor warranty. If you receive labor warranty, you're getting it from your installer which may or may not be around in that time frame and with 50+ inverters in a system out on the 100+ degree roof in the elements the odds of failure are much higher than a string inverter in a weather protected garage. Having said that, 25 years is significantly higher than the 10-12 years other manufacturers provide. I'm going to say anything that costs over $1,000/kWh for storage is ridiculously expensive. I think it all comes down to the size of the solar system and the size of the battery storage what system makes the most economic sense for any individual user. If you're installing small 9-10 kWh battery storage, then the excess cost of the battery might not be as much of a difference maker, especially if you're pairing it with a smaller set of panels. But for larger systems in the 20 kW+ range with 30+ kWh storage the Enphase system just becomes cost ineffective as it has no economies of scale discount with larger systems, you just end up buying more of the same.
My business has installed just over 55,000 residential systems and 2500 commercial. Enphase is without a doubt the most reliable inverter available in the market and once multiple roof planes or shading is in play, vastly more productive in the real world. As a business we provide a 30 year warranty on the entire system outside batteries and we do so with extreme confidence. Only time I wouldn’t want enphase is for large ground mount or commercial buildings on a mono tilt and there we exclusively use sol ark
You were trying to explain everything in laymans terms which is fine. But as an engineer I can say that you state a lot of incorrect information. I had to dislike the video and write this comment when you started talking about microinverters feeding the panels and inverter feeding the battery.
Thanks for your feedback - perhaps I miscommunicated - DC current from each panels is input for the microinverters. They convert that into household 240 volt center tapped AC. The microinverters in the Battery are bi-directional. They convert the AC from the grid or the the AC from the panels (converted by the rooftop microinverters) into DC to charge the Battery. They are also able to work in the reverse direction and convert the DC output of the batteries into regular AC. Again my apologies if my video is misleading.
