- Many solar customers think their system will work in a power outage, and unfortunately, that wasn’t true until the revolutionary IQ8 Microinverter. See a lab demonstration of how a Sunlight Backup system handles high energy demand, and even cloud cover, with more intelligence than ever.

The fact that you can do all of this WITHOUT a battery is incredible!
When they can use a parked EV on a standard charger as their battery we will be talking.
@@crhu319 look at their recent acquisition, "Accelerates the Enphase roadmap to enable bi-directional charging capability for vehicle-to-home and vehicle-to-grid applications"
Enphase, you need more videos like this, in the lab with the engineers, less glossy videos
Agreed. For the portion of the population that's fed up with 'flashy' bravado of a certain other big-name solar company, these videos (of nerds talking about nerd stuff and demonstrating how stuff works in an actual lab designed to test said-nerd stuff) are actually refreshing.
Great demonstration of Enphase Software in the best hardware working in real life for the best solar energy solution money can buy.
Just purchased my first 5 IQ8s. Very excited... keep these types of videos coming please.
Great demonstration. Thank you.
Great video. The inverters have very nice output characteristics for these overload cases.
Thanks Donny for the demonstration. Loved it & the technology.
Great demonstration!
Awesome. This is exactly what I was wondering.
That is an amazing simulation! I'm so proud to be an Enphase Installer in Texas
What additional components are required ?
The Enphase IQ8 will be a Game Changer especially in poorer countries like India, Africa, China, you name it when you can’t afford a battery yet. Incredible demonstration! 😊
It needs to use vehicles as batteries
@@crhu319 It will also come. However, very few car companies would give their battery a warranty if cycled once per day as battery for a house. Hence, I believe in separate batteries for the house. All possible with Enphase.
Best engineers in the business :)
agree 100%
Love this! Any word of when this will be compatible with houses with Generac all house generators?!
Does the Sunlight Backup work for a 3 phase installation?
Could you please share the interconnection of sunlight backup system with an pv shedding kit.
To confirm, you need their enphase sunlight backup, correct? This isn't going to work with just their iq8 microinverters alone
Hello from a beginner. This is interesting to learn a battery is not necessary here. Friendly suggestion: could you do a brief video on how a DIYr might piece together a small system, as you will be selling these? Or are they part of a bigger package a homeowner must buy? I know you do home installations, but will people be able to purchase independently? How does it work? The more you can educate people the more you could sell. Thanks for your consideration.
Check Pacific Sun Tech video, they will compare the 4 different systems. It looks like there is only 2 additional device you need to add (IQ System controller 2 and essential load solution). The installation should be similar but I guess the Solar companies who order first will get it before the general public.
Distributors typically have deals with manufacturers to prevent independent purchasing. You would likely have to purchase from a local solar company or possibly a distributor. The iq8s have been given priority to certain companies and aren’t at full scale production
Nancy Chace, There are a number of really good DIY Solar Channels that I recommend for beginners. Off Grid Garage, Digital Mermaid, DIY Solar with Will Prowse, Bobby's Solar Homestead, Lithium Solar, DavidPoz. These are my favorites and I also have a couple of videos posted on YT myself. Hope this helps.
Does this require a critical load panel or is the pv and iq8 backing up the entire main panel?
I had a rep at my house today going over some of the financial details as we prepare for a large (~17kW) array w/ one 10kWh battery. We're an all electric contemporary house out in the country. Discussing that very thing he told me the combiner (IIRC) has four 20A circuit breakers. So if that's all you need powered that would be enough. I have a 220V water well pump. I will need a subpanel.
So important question. Can the previous generation use this like 7a or is it more the IQ load controller. And if a 7 series needs a firmware update to work as a sunlight backup.
Main difference between the 8s and the 7s is a firmware update. There are some other subtle differences regarding the electrical specs but major change is the firmware. 7s most likely won’t ever receive this because it won’t encourage new sales to the 8s
Wont work. Pony up for the iq8 😂😂
so i have a van 1 solar panel 1 iq8+ capable of generating about 200 W how ever so far i have not bin able to find how to make it work such as here without getting power from the net when ever i try to google it i see enphase telling me by a controller 2 buy a battery 2 things i dont need from enphase for a van when i go to youtube i see people do this without being connected to the net can somebody tell me what i am missing ?
Need to be sure you get the System Controller 2, not the older System Controller (model ending in US00). The older one only works with IQ6 and IQ7 series microinverters.
Is there any point in having direct sunlight backup if I also have a battery?.. or is it a moot point then? Thx
Wow!! 😊😊😊
Great video and great feature....But my understanding is that some additional components are required over and above the normal solar installation for this "Sunlight backup" solution to work, right? It would be nice to understand what those additional components are and roughly how much more it will cost to purchase/install the additional components AND if a user starts with this "Sunlight backup" solution and later decide to add a EnPhase battery are those additional components that were purchased for this Sunlight backup solution simply "throwaway"? Or are they necessary as part of a backup solution (i.e., used with battery backup solution.). Also, is there a risk during "brown out" that you could damage any appliances during these brown outs. And even if there is a theoretical possibility of causing damage is there a simple way to mitigate that potential (e.g., plug in devices you plan to power into a power strip with built in surge protector?).
Your questions are my concerns. Guess we need to throw away the AC Disconnect if you upgrade from Solar only to Sunlight Backup and the throw away the two load controllers, load centers when you upgrade from sunlight to full battery backup! Why can't they incorporate the load control into the System Controller 2?
ok questions.... it seems you are saying that these new microinverters can operate as backup power, for when the grid goes down, but only when the sun is shining (it will deliver AC power directly to loads). my questions --- 1) if the grid is down and there is nowhere (no charge controller or battery) to put the energy (unless there are adequate loads calling for power) where does the extra power go? 2) does this comply with grid shutdown requirements? How are you isolating the power from the grid so you don't feed power back out? 3) do you need a dedicated sub panel for vital loads, or does this just feed the entire house when the power goes down?
Good questions. Anyone?
Same questions here, plus how does this integrate with a parked EV on Green PHY standard CCS charger.
The micros shut down and throttle the power, we are talking about Enphase of course they comply with grid shut down requirements. They were grid shut down compliant before everyone else
@@guidedbygreen1480 throttle? Hmm. Do they have a heat sink for that much power? I know you can shut down or open circuit without a heat sink but can you throttle?
@@garybeckwith not sure. They have installer live webinars pretty frequently, if you'd like you can attend one of those and you can ask the trainers if it's not discussed in the webinar to get a better understanding
Can you re-do this demonstration with a TV, microwave, and a fridge?
i about to solar my roof. I have 30KW EG4 battery bank. does this system work with my Battery pack?
So cool. Now what are the IQ8s going to cost?
per my calculations, around $25~50 more than IQ7+ (based on Pacific Sun Tech video).
CED prices the IQ8+ $50 more than the IQ7+
This would be good for non-critical day-use appliances/tools/etc. Always gonna need batteries for night time though.
or you just go to bed.
@@jeffshaner3823 Yeah but people dont work your typical 9-5
I hate to be a pessimist but the long wait sort of becomes all sizzle no steak. What exactly does the IQ8 do that the sunny boy inverters with backup power built-in don't? Without all the additional cost? The concept, while intriguing is a misnomer due to the fact all the additional hardware that one Hass to buy sending the price through the roof.
Well you’re definitely a pessimist. Enphase is a superior inverter and will make much more energy during its expected 30+ year life, especially if the panels aren’t all facing the same direction
I think the sunny boy only alots up to ~5 kW (dont quote me) during grid down mode. So not enough to power your house most likely. I think, in theory, the IQ8 gives you whatever amount your panels can produce.
explain inrush current is from inductive component of impedence within an inductive motor. in the vaccum. Inverter has to adjust phase angle to the complex conjugate in order to maintain maximum power transfer.
That is one really great stability algorithm! Makes my house seem like its on a 'weak grid'.
If everyone used enphase instead of grid following we would have fewer datacenters in the world running pointless algorithms.
What about an induction motor like on a fridge? Won the brown out ruin the motor?
same question I have, other than that this is super compelling. I am getting an IQ8 system shortly.
I'd love to know the same.
Don't you think if the grid goes down and you manually turn off the main 200A breaker in the Main Service Panel, that Main Service Panel should become an off grid panel ? That way the solar panels should supply power to your home? Anyone??
Ya, this is a demo to connect to a load which is easily set. But how do I make the connection to a branch circuit that is a branch circuit in the main service panel, say, my refrigerator? Anyone ?
Really cool. When do the IQ8 inverters become available? My understanding is the industry thought they would have become available more than a year ago.
There was a press release, today.
@@gianthogweedlives Wow. That's pretty amazing. Looks like December they'll start shipping
Can you list all the components used in your demonstration system besides the microinverters for a net-meter install when the grid is down?
How does rapid shutdown work with grid-forming inverters?
The "System Controller 2" isolates from the grid and sends a signal enabling the micro-grid intentional island mode.
What if instead of having 1k watts, I have 18Kw solar array. Can I run my AC and well pump?
He probably has a 3.5ish kW system (10) 350W panels. The 1000W piece is only stating that it’s a sunny day and 1000W/ square meter is what you can expect during full sun. An 18kW system is super big, and can only be hooked up via “line side tap” in most situations. You need to speak with a local contractor to see what size system works for your home and needs
Can I graft these onto my existing non-enphase grid-tie solar system? Who can help me do that if so?
Only for iq8
Nice product until something goes wrong. No customer support. Ask for tech support and they will contact you once every 3 days. Simple answer turns into long drawn out event.
If you have a PV system attached to the grid and if the grid has a power outage; do you need an Enphase Empower Smart Switch to go off grid and have this sunlight backup option to work?
You need load center
