Enphase Labs: Sunlight Backup​ 

The fact that you can do all of this WITHOUT a battery is incredible!

Enphase, you need more videos like this, in the lab with the engineers, less glossy videos

Thanks Donny for the demonstration. Loved it & the technology.

Great video. The inverters have very nice output characteristics for these overload cases.

Best engineers in the business :)

Great demonstration of Enphase Software in the best hardware working in real life for the best solar energy solution money can buy.

Great demonstration!

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.

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?

This would be good for non-critical day-use appliances/tools/etc. Always gonna need batteries for night time though.

To confirm, you need their enphase sunlight backup, correct? This isn't going to work with just their iq8 microinverters alone

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.

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?).

Love this! Any word of when this will be compatible with houses with Generac all house generators?!

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 ?

Can you re-do this demonstration with a TV, microwave, and a fridge?

Does this require a critical load panel or is the pv and iq8 backing up the entire main panel?

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 ?

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.

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.

Could you please share the interconnection of sunlight backup system with an pv shedding kit.

i about to solar my roof. I have 30KW EG4 battery bank. does this system work with my Battery pack?

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.

Can I graft these onto my existing non-enphase grid-tie solar system? Who can help me do that if so?

Wow!! 😊😊😊

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?

How does rapid shutdown work with grid-forming inverters?

Does the Sunlight Backup work for a 3 phase installation?

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! 😊

What about an induction motor like on a fridge? Won the brown out ruin the motor?

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.

Great demonstration. Thank you.

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??

Is there any point in having direct sunlight backup if I also have a battery?.. or is it a moot point then? Thx

So cool. Now what are the IQ8s going to cost?

What if instead of having 1k watts, I have 18Kw solar array. Can I run my AC and well pump?

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.

Just purchased my first 5 IQ8s. Very excited... keep these types of videos coming please.

Awesome. This is exactly what I was wondering.
