Capacity and battery

Capacity
3,072 Wh (Nameplate capacity The capacity printed on the box, in watt-hours (Wh): what the battery holds when new. You get less out of it in use, because the station keeps some back to protect the battery and loses some turning it into 240 V or 12 V power., Usable capacity How much of the box capacity you can actually draw out. Most brands don't publish it, so the box figure is the only one that can be compared. not stated)

Battery type The type of cells inside the battery. Most power stations now use LiFePO4; NCM, short for nickel cobalt manganese, is the other type that turns up.

Ah at 12.8 V Capacity in amp-hours, the way a 12 V lithium battery box states it, so the two can be compared. Worked out from the Wh figure: Wh ÷ 12.8.
240 Ah derived: 3,072 Wh nameplate ÷ 12.8 V = 240 Ah
Price per Wh The price divided by the capacity on the box, in cents (¢) per watt-hour (Wh). Lower means more capacity for the money.
126.9¢ derived: $3,899 (price today) ÷ 3,072 Wh nameplate = 126.9¢ per Wh

Capacity is the nameplate figure in watt-hours (Wh), the one on the box. AC output is the power a station can supply non-stop, not a short burst. Weight is the station on its own. A figure measured another way is shown with a note saying how, and isn't compared with the others.
