Remember your solar powers the house directly during the day. I have a single Powerwall and my evening use never reaches 50% of capacity and is usually only around 30-40%. I have gas appliances and don't run AC off the solar and Powerwall.

Around 50A continuous and surge of close to 150A

I also use around 40 to 50 kWh per day on South Florida. But my battery is only 25kwh. I received a notification when running off grid so I can shut down the water pump, rise temperature on thermostat, turn off any phantom load and move the consumption to the daytime when the solar PV is working

@@Edu-Rodriguez It'd be nice if there were a device that would turn all those things off for you automatically during an outage.

@@Constitution1789 you could set up a non-critical load panel or going the high-tech way using something like a smart Span panel. There are many ways

How lol 😊

A very friendly sales rep in Vegas during 2023 SPI event. But remember that these scalability features will be available overtime on a OTA software update

Termites use passive cooling for their dwellings because they have to, and we use AC because we can. And because our economic appraisal is so limited in scope and in duration, it seems to support it. But you don't have to step back very far from the problem to take in the fact that someone somewhere is cutting down trees or burning fossil fuels to make the electricity to power your AC, and that this and the CO2 released to build the machines to mine and refine the lithium AND the even more CO2 to actually mine and transport it and to make the batteries and panels you want...is only increasing the already high temperatures....which in turn will make you want more AC. Have we thought this through?

EG-4 PowerPro 14.3KW and 18Kpv inverter Less then $10k for both fully certified even in California. With two EG4 18Kpv inverters and 6 PowerPro wall batteries you can have 85.5KW of capacity. Total cost $34172 directly from Signature solar.

@@falfield idk what you’re spewing out but in western Washington our energy is 80% renewable hydropower and solar battery farms are expanding, in less than 5 years we’ll be close to 100% renewable. Battery tech is changing and so lithium & cobalt free batteries are a thing now. It’s like flip phone to iPhone. It’ll happen fast.

@@kevinmanan1304 If as you say, you REALLY don't know what I am 'spewing out' then you - by your own words - disqualify yourself from making a contribution. It's clear that you don't understand the concept of embodied carbon. But hey, when has blind ignorance stopped anyone from holding an opinion and insisting it Trumps others'?

@@falfield I meant it as what you’re saying is far from the truth. Unless you’re in W Virginia, your power is much cleaner than you think.

It may require a new string to connect the panels, since the new inverter has a wildly unknown capacity for panels. Restringing is not a huge expense, but it can expose faults and damage that was ignored. Judging purely from the fact it has 6x MPPTs, the assumption is that the solar inverter capacity is 11.5kw shared across a maximum of 15kw of panels given oversizing of 133%. This also creates an odd situation where most inverters only have 2, or occasionally 3 MPPTs capable of half the load capacity. If they literally put 3x 5kw solar inverters circuitry inside the PW3, then it creates a strange situation where you have 2.5kw of panels per string, and ~1875w per string. This can be a good thing, but it also reduces the potential capacity if your roof isn’t symmetrical or you need a small string facing another angle, of 4-5 panels, alongside a string of 11 panels. This works okay if you have 400w panels from Value brands like Jinko, Trina, et al, but some of the new panels are over 500w, and require expensive mounting/ skirting for snow/ice which may not be compatible with the voltage range accepted. The new panels can be a nuisance for an inverter which doesn’t have an optimiser option to lower/boost the voltages. And that’s mostly because the small strings can only have 5-6 420w panels. Each MPPT will be quite small, ie that 15kw could be 11kw if you choose cheaper panels or expensive panels. If it is basically a retrofit 3x 5kw solar inverter, this could explain a lot of the load and DC conversion numbers. It also allows people to put extra panels in shaded areas or at angles which may receive less sun, such as Northwest, East/West or at a steep angle of 28-30’ which would be less efficient. By moving the weak or shaded panels to a smaller string, the cost can be offset by the potential minor gain. Normally, these awkward strings are ignored, because they tend to cost $1k to mount and wire 3-4 panels before even buying the panels, which won’t produce much power over the whole day, due to shading.

I have heard the Powerwall 3 can be connected either by AC or DC so one or the other will support legacy solar systems.

Powerwall 3 uses LiFePo4 cells

PW3 will use LFP batteries.

Why would an average home need 40kw of storage?

@@simonpaine2347 They do if you want enough power. Look it up.

Pure BS! You really don't know what you're talking about. Plenty of people live just fine on one of these. I live in a large house and use about 8 kWh per day. I've done hundreds of installs where the customer was educated on energy efficiency first before investing in a massive battery system.

I have an average home. 1 powerwall 6kw solar panels. $18k (after tax credit) $22k without. -FYI

@@simonpaine2347 The unit for storage is kilowatt hours. The power output of an inverter is kilowatts.

Powerwall3 is vapour at the moment, so if you're mid-installation, it's an irrelevance. As for whether your installer's claims are correct or not, many factors might play into it, making an universal answer impossible. Ask him to explain in detail WHY he says this: if he talks about long DC cable runs it would be worth listening to. You could look at the datasheets for the conversion efficiency figures. But if he blusters, then maybe he just wants you to hand over some cash today rather than to prevaricate until the day when the Powerwall3 is actually available to base some realistic plans on.

Powerwall 3 uses LFP cells which are safer and last much longer than NCA/NMC cells.

Yes, it would be efficient. It would also be expensive. The assumed configuration is that the powerwall 3 would be similar to 3x 5kw inverters. It would be difficult to predict how the strings are run before guidance and manuals come out, but the usual approach to inverter strings of panels, is that they are tied together as a group, or grid. Enphase is useful when your roof does not have the standard rectangular shape, and the panels can’t be put into a grid layout. Each traditional string of panels is efficient when they act as a cohort. But if one panel gets shaded, the performance drops by 1/6 to 1/2 for all panels. Partial shading drops the wattage and power of the whole group of panels. This is a traditional flaw, but also an efficiency. Each MPPT handles the group or string of panels separately. So if you had a 5x5 grid of panels, it’s assumed that you would have 2 strings of different lengths. 12 + 13 or 10+ 15 sic. Because there’s 6 strings possible, you could have 5 strings of 5, and the group would be run horizontally ie because the sunrise to midday angles would make the bottom row, perform better earlier in the morning, and worse in the evening. Or vice versa depending on the side of the house. Smaller strings make shading loss less noticeable, optimisers can boost all panels on the same string. Microinverters, you can face them upside down and it won’t affect the overall solar. It would be expensive though as instead of one box on the wall that handles the conversion, you need 20 small inverters on standard AC home wiring (sold by Enphase, with exclusive connectors) The overall advantage of Enphase is you can spend more. And you get more. That’s the main advantage. If you want to upgrade, you don’t need a second $4k inverter and planning, you can just add a combiner box, run the new panels on a chimney, or somewhere stupid, and you’ve added 4kw. Or, in a better example, a carport or shed tied to the house circuit, where you also have a EV charger. They will not be on the same wiring, but they can share the same conduit and infrastructure, where a normal Solar install requires a nearby inverter and separate grid safety/isolation/wiring and other equipment.

....and how many (of the as yet un-released) Powerwall3 have you installed, exactly? You fail to realise the foolishness of what comes out of your mouth....but you open it anyway.
