I can’t get over that price tag of $33,000. That’s completely outrageous for the hyper majority of people. That’s almost double what I paid for a used model S in February for 1/5th the capacity and 6 months of bureaucratic hell. Yes, I know “location, location, location” but be honest Matt, you know that’s a ridiculous price for most people even if it may be average for your area

What I’d dearly love is to be able to produce gasoline from my solar panels, that could be stored for months or years and used by all existing tools and car.

Another full length advertisement.

So you can’t expand to 25kWh without adding a fire sprinkler system? Don’t regulators know water doesn’t work on battery fires?

5KWh storage is equivalent to 1Kg wood in thermal energy. So literary any (fairly small) branch of wood found in the forest has 5-10x (thermal) storage capacity of these expensive batteries, given efficient burning process. To con vert to electric one needs a high efficient thermodynamic transformer – a boundary layer turbine, and a small 2.5-5KW permanent magnet motor/generator.

How many days can these batteries power your house when there is a storm outage? Ignore EV charging because you can drive to a supercharger. Living in Massachusetts, I’ve had power outages for 3-4 days, requiring a generator.

I had the interesting experience of trying to clean my solar panels the other day. It became extremely dangerous and I started slipping off my roof when it became wet. I won’t be trying that again. I wonder if this is factored into people’s calculations when deciding to go solar or how to design the panel access. I would imagine the cost of having someone clean the panels every 6 months would have a great effect on their cost effectiveness. I’m surprised no one seems to design a safe way to access the panels on the roof.

"The best sponsor I can shill for" There I fixed your video title for you Matt.

A Hyundai Ioniq 5 has up to 77 kWh and can output 3.6 kW with V2L… so, if you anyway have an electric car in your garage that's usually kept at 80% you have as much battery as 12 of those units in an emergency… how often does your household need 12 kW output?

What you need is just enough batteries to run your fridge etc. And enough capacity to fill up with solar while your car isn't at home.

In other words, I think you're buying too many small batteries at a too high price if your vehicle is already electric. Spend the money on control circuits instead.

Here in the Netherlands the company homewizard advertised with a battery that is just plugged into a wall outlet. Stackable. Very interesting. €1395 2.7 kWh 800 watt. No extra costs just plug it in.

The Ecoflow PowerOcean DC Fit is the most intelligent innovation since a long time ! A it uses CATL LFP with 6000 cycles

As you mentioned, the prices in Europe are significantly cheaper. One such module is offered for 3500 € installed by the company who installed my solar panels 4 years ago, with Enphase inverters, so it will be plug and play.

Thanks for the detail on the SPAN integration it was very helpful.

I hate my enphase system. The setup process is a huge pain constantly waiting for microinverters to provision and 3 out of 4 of my microinverters stopped outputting power. I should have just bought a cheap Chinese grid tie inverter.

0 % Loan . Too bad they don't do that for student loans. Instead forgiveness. Oh well its just the rest of us paying for the few

12:08 That's insane for LFP. Even more insane when you consider how a Lithium Ion fire burns AKA that a sprinkler system above it would likely not do anything in the extremely unlikely event you did have a battery fire. Did the fossil fuel industry bribe your local gov't for that? Or perhaps a local gas/diesel generator company?

Mandatory sprinklers for battery backup in the garage, but no mandatory sprinklers for the 15 gallons of gasoline in the average person's average gas tank. That's over 500kWh of potential (flammable and explosive) energy, compared to the puny 60kWhs in the Tesla…

I don't know a firefighter that parks their Tesla in the garage. That says something.

How would a sprinkler system get through your water-proof car to its fire?

what about connecting solar panels directly to water heater ,it will be best storage, and we used a lot, takes a lot energy to warm up, another tank will just keep steady temp. for use

Would be curious to see your ROI schedule.

Massachusetts is progressive. Crony businesses lobby for required systems. Sprinklers is the long lasting scam.

If Tesla allowed their EVs to backup the house, that would be 70Kw or more!

New intro pretty good but older was better

12:35 Do I need a Sprinkler System for storing my EV in the garage…Nope…..( Not Yet ?? )

Six months is fast compared to Hawaii. It took 11 months for my recent home PV/battery system to complete all phases of the project.

@UndecidedWithMattFerrell

Matt, I have serious concerns about the safety of lithium based batteries, regardless of chemistry. There are alternatives. What are your thoughts on those alternatives and why didn't you go for one of them?

That's really clever of Enphase to use multiple inverter modules inside that they already make. It's just a parameter adjustment.

Food from a plastic container? Is it healthy and safe ?

Hey Matt, how do you suggest condo owners should setup solar? Apart from cost, as there are space and grid regulations, is going through the hassle even worth it? Appreciate the detail in your videos

Looks good to me. I think your going to be very happy with it. 🙂

Fight desertification, and work for reforestation! Burn fossil fuels, early and often!

Would you have gone for mostly the same system if you were off grid?

I ended up getting the Enphase 5ps as well. Well, still in permitting hell. Been 3 months already.

Thought really hard about EcoFlow but ultimately decided to stay within the Enphase ecosystem. There's a big software component to these systems nowadays and Enphase is a bit more mature in that space (vs say, Anker or Ecoflow who could abandon their app anytime).

Also looked into Span. My installer strongly discouraged it. Thanks for sharing your thoughts about that, sounds like not getting Span was a good call.

Those batteries wouldn’t last 24 hours in a storm event. A generator with 2×120 gallon LP tanks can last 4-5 days on a 3,000 sqft house in summer. This isn’t even close for a backup power solution. This does provide continuity of power for a while.

Or just buy a Ford f150 lightening and realize it is a poor vehicle but an awesome battery bank for your house that you sometimes get to drive…. Cheaper.

I am getting an enphase battery once the 10 year contract I got with Duke energy expires.
Since I have 1to1 purchase of my solar. Batteries make little sense right now.

We've had Enphase for more than a year now, and we're very happy. But, a system with the same storage and less generation here in Puerto Rico was $47,000. No regrets.

FranklinWH FTW

Purchase a salvage EV. Park it on your wall. Add some wires. Done.

HAHAHA you lost me at $33k beyond the solar panels. I hadn't even thought of this but you're better off buying a storage tank and having a generator.
you say "waiting for a part" as if these companies would supply repair parts to consumers lol
right to repair is a myth outside of ICE vehicles and even there it's getting phased out

What are you saying? you said $275/kw durring load shedding event. do you mean $275/kwh? i pay $0.10 / kwh. for power. I cant bellieve the gov would pay $275/kwh.

Kind of ironic that a company that is know for turning DC solar into AC right at the panel would have a battery solution which by definition is DC. Wonder if there's a microinverter like solution that doesn't need microinverters, like pulling a separate wire from each solar panel to conditioner all the MPPT tracking while in DC to charge up your batteries, then just use a regular inverter to convert it back to AC power. Sure there's a lot more wires to pull since each panel needs a wire, but that's gotta be cheaper than (at least equipment wise) than microinverter for each panel, then multiple inverters at the battery to convert back to DC.

Oh and do you need to connect to the grid to get those rebates? I would think being part of the virtual power grid would end up costing you more money in the long run because your VERY EXPENSIVE batteries won't last as long.

The chain dragging on EV uptake is still lack of home charging ability for so many. Have your own driveway, EVs are a no brainer if you're buying new.

My mum lives in a popular restaurant precinct without off-street parking. She regularly has to park up to a block away from her own house. So despite owning her home and having a moderate sized solar system, she can't use it to charge her car.

There is only 1 Tesla supercharger in the whole of the Australian state of Tasmania!

Until this issue is solved, EV uptake will struggle to get beyond a certain percentage, and I am a massive EV convert.
