Powerwall LiFePO4 Battery - 8.7kWh Home Pack
This page describes a home battery pack listed at 8.7kWh, model YB-WM48170L as listed, based on a 48V pack at 170Ah. The headline figure on this page is the listed 8.7kWh value, not a rounded 8kWh label on its own: the search description for this page uses the rounded form only as a retrieval description, while the page itself states the precise listed value wherever the capacity is given.
Listed specification in context
The listed specification gives a nominal voltage of 51.2 V, a capacity of 170Ah and a stored energy of 8.7kWh. The charge voltage is listed at 58.4 V, the discharge termination voltage at more than 40 V, the housing material as steel in the listed material, and the internal resistance at no more than 25 milliohms. The recommended charge and discharge current is listed at 0.2C, with a maximum charge and discharge current of 150 A. Those figures describe this home pack only, and they should not be read across to the smaller or larger home packs.
A home pack at this size is often considered where the smaller home pack does not cover the load, but the larger home pack is more than the house needs. That comparison only works if the load profile is known. The sizing guide on this site explains how to think about daily energy use, peak load and backup duration, without giving a capacity recommendation for a particular house. A buyer should compare the three home pages on their listed figures, then enquire with the load and inverter details.
What is not listed for this model
Dimensions, weight and a full protection list are not given for this model in the listed material used for this page, so they are confirmed per model in the enquiry rather than borrowed from another model. Cycle life is also not stated for this model on this page, for the same reason: a cycle figure from another model would mislead a buyer who is comparing home packs. If any of those values is needed for an order, the enquiry should name this model and ask for that value specifically.

Frequently asked questions
How do I get a quotation?
Send an enquiry with the voltage, capacity and quantity you need, plus the application. Quotations are confirmed per order, and specifications are confirmed per model before payment. This site does not list fixed selling figures.
What certification documents can you provide?
ISO 9001 is stated by the company. Certificates are available upon request. If a buyer needs a certificate for a specific model, ask for it in the enquiry and name the model, so the correct document can be checked.
Are the specifications on this page valid for every model?
No. Specifications are shown per model and must not be read across the whole range. Where a value is not listed for a model, the page says to confirm per model rather than filling in a generic figure.
