LiFe02 batteries for home grid-tie systems run about $150/kwh (10kw grade A 200ah cells) at the consumer level. Inverter capacity runs about 3k$ for an 18kw grid tie inverter. So, in order-able parts it costs about 5000 total to build a 10kw “power wall”. It seems like there should be (and probably are) comparable integrated solutions around the 5k price point, which would be something like 500 per KWh. At any rate, at sizes under 20kwh the battery is likely to be the smaller part of the cost of the unit….which also makes it possible to build an 80kwh system with 18kw capacity for around 18000 dollars, so there’s that. So in short, yes, it’s probably the inverters and the branding that make up the vast majority of the powerwall price.
