In October 2016 Tesla and SolarCity announced a new “solar roofing” product along with new versions of the PowerWall residential battery and the PowerPack commercial / utility-scale batteries. The full video of the announcement can be watched at here. This advisory focuses on the new batteries. The solar roofing tiles will be addressed in a future advisory when more information is available.  \nThe PowerWall 2 has a capacity of 13.5 kWh / 7 kW and costs $5,500, including an integrated inverter or DC/DC converter. Their website estimates installation and supporting hardware “start at” $1,500 . (Tesla notes that “total cost excludes sales tax, permitting and fees.”)  \nThe new PowerPack has doubled the capacity of the original version to 210 kWh and includes either a 50 kW DC-AC inverter or an equivalent DC-DC converter for use with larger systems. Tesla also talked about tighter integration between solar, batteries and EV charging, but provided no real details about how this would work.  \n\n|  | PowerWall 2.0 | PowerPack 2.0 |\n| --- | --- | --- |\n| Useable capacity | 13.5 kWh-AC | 210 kWh-AC |\n| Power (continuous) | 5.0 kW | 50 kW |\n| Power (peak) | 7.0 kW | 50 kW |\n| Voltage | 120/240 single phase | 380 to 480V, 3 phases |\n| Power Electronics | Inverter or DC/DC converter | Inverter or DC/DC converter |\n|  | included | included |\n| Depth of Discharge | 100% | 100% |\n| AC Round Trip Efficiency | 90% | 88%-89% |\n| Dimensions | 44\" x 29\" x 5.5\" | 51.5\" x 32.4\" x 86\" |\n| Weight | 264.4 lb | 3,575 lb |\n| Operating Temperature | -4° to 122°F | -22°F to 122°F |\n| Scalable | Up to 9 Powerwalls | \"infinitely scalable\" |\n\n1 [https://www.greentechmedia.com/articles/read/chart-the-us-behind-the-meter-storage-landscape](https://www.greentechmedia.com/articles/read/chart-the-us-behind-the-meter-storage-landscape)  \nCopyright © 2017 by the National Rural Electric Cooperative Association. All Rights Reserved.  \nFebruary 2017  \nWhat do you need to know about it?  \nThe PowerWall 2.0 has 13.5 kWh of storage, more than double the final specs of 6.4 kWh of the original PowerWall. The unit now also contains either a 7 kW DC-AC inverter or an equivalent DC-DC converter. If used with a PV system, the AC version would still require a PV inverter, while the DC version would require a multi-mode inverter (such as a SolarEdge™ inverter) . The warranty is 10 years of unlimited cycles for “solar+backup”2 with final capacity of 70% of the original rating.  \nThe price of the complete system is now $5,500 for the PowerWall 2.0 before installation. This is just over $400 per AC-kWh. In its pilot program announced last year, Green Mountain Power was selling a complete solar-ready PowerWall system (6.4 kWh rating) to its customers for $6,500 before installation. This works out to just over $1,000 per kWh-AC, so if the PowerWall 2 specs hold true, this is a 60% drop in the cost of energy from the original PowerWall by itself, or approximately 40% drop if you include a solar inverter. As a price comparison, Electrek points out that a 4 kWh “sonnenBatterie eco compact”(which includes a connection fora PV system) costs $5,950, or $1,500 per kWh-AC3 .  \nThe new PowerPack, aimed at the commercial and utility-scale market (Tesla mentioned Kauai Island Utility Cooperative in their announcement video), has a capacity of 210 kWh (vs 100 kWh for the original PowerPack) and now includes either a 50 kWh inverter or a DC-DC converter which can be used in larger systems connected to a central inverter. According to the Tesla website, a single PowerPack 2.0 costs $109,000 plus installation, which works out to $520 per kWh-AC.  \nWhat you should do about it  \nThis event was widely anticipated and extensive","cbCaitiDvqpiuN0e","https://ap.wps.com/l/cbCaitiDvqpiuN0e","pdf",380663,"English","# What has changed?\n## PowerWall 2.0 overview\n## PowerPack 2.0 overview\n# What do you need to know about it?\n## PowerWall 2.0 details and economics\n## PowerPack 2.0 details and economics\n# What you should do about it\n# Additional Resources","[{\"question\":\"What are the main changes in PowerWall 2.0 compared with the original PowerWall?\",\"answer\":\"PowerWall 2.0 increases storage to 13.5 kWh and includes either a 7 kW DC-AC inverter or an equivalent DC-DC converter, with system integration and warranty details summarized in the advisory.\"},{\"question\":\"How does PowerPack 2.0 differ from the original PowerPack?\",\"answer\":\"PowerPack 2.0 doubles capacity to 210 kWh and includes either a 50 kWh inverter or a DC-DC converter for larger systems using a central inverter.\"},{\"question\":\"How should co-op members respond to the residential battery price reduction?\",\"answer\":\"Members are expected to seek more details from trusted sources, starting with asking their co-op, and can place orders via the website with specified refundable deposit credits.\"}]","Technology Advisory - Tesla / SolarCity Announce New Residential and Utility Scale Batteries | PDF"]
