\"powerwall<\/p>\n

A presentation by a Tesla USA employee, now circulating on YouTube, has provided substantial new information on the Powerwall 3’s confirmed specs.<\/p>\n

My February summary of the Powerwall 3’s expected specs<\/a> contained several ‘to be confirmed’ speculations.<\/p>\n

This blog post confirms that every speculation, besides the cell chemistry, was correct. So let’s start there:<\/p>\n

Confirmed: Lithium Iron Phosphate Cells<\/strong><\/h2>\n

Lithium Iron Phosphate (LFP) cells in the Powerwall 3 have finally been confirmed after much speculation.<\/p>\n

The new cells are warranted for a capacity retention of 70% at 10-years, but the Tesla presenter said they anticipate real-world performance to be 80-90% after those 10 years.<\/p>\n

He also said Tesla has observed:<\/p>\n

“battery degradation is more a function of time than use”<\/p><\/blockquote>\n

If accurate, that’s a great argument for cycling your battery as hard as possible to get the maximum ROI instead of carefully limiting the cycles to reduce wear and tear.<\/p>\n

Confirmed: A software update will allow AC coupling<\/strong><\/h2>\n

A software update scheduled for April 2024 will introduce AC coupling capabilities to the Powerwall 3, allowing integration with existing solar installations. Without this update, the Powerwall 3 would only be suitable for installation at the same time as a new solar array, DC coupled to the PW3’s integrated solar inverter.<\/p>\n

Confirmed: Cheaper DC Expansion Packs<\/strong><\/h2>\n

Tesla will be releasing 13.5kWh DC Expansion (DC-X) units, which are expected to be priced around US$1,000 less due to the omission of the solar inverter and site controller electronics. This potentially prices a DC-X at under $9,000 Australian dollarydoos. That’s a beastly $666 per kWh.<\/p>\n

The DC-X form factor will be the same as a PW3, with the potential for up to four PW3s and twelve DC-Xs per Gateway. That’s a maximum of \u00a046kW AC and 216 kWh capacity with 16 units on a single gateway. Impressive.<\/p>\n

Confirmed: 11.5kW solar inverter output plus 5kW battery charging<\/h2>\n

The Powerwall 3 can send 11.5 kW of solar to your home and charge the battery at 5kW simultaneously. Great for slurping up 16.5 kW of solar power from big arrays, reducing curtailment.<\/p>\n

Powershare: Vehicle-to-Home Integration<\/strong><\/h2>\n

Tesla’s Powershare V2H feature currently requires:<\/p>\n
