Electric clothes dryer: how much battery you need
Electric clothes dryer draws about 5000 W (4000–6000 W range), runs 80% of the time and uses 4000 Wh per day. Start-up surge: 6000 W.
An electric dryer runs on 240 V and is one of the largest loads in a home; a line or a gas dryer is the outage plan. Champion lists 4000–6000 W running; we use the middle for energy and the top starting figure (6000 W) for the peak.
