The actual batteries of the Bluetti EP900 system are the stacked B500 batteries, each with a 90% depth of discharge. The lower the depth of discharge, the less of your battery's maximum capacity you'll be able to use. Depth of discharge is how much energy you're able to drain from your battery's maximum capacity without causing damage to it. The battery's depth of discharge is a bit lower than the competition. The EP900 has one of the lowest efficiency ratings we've seen, at 85%. Most home batteries nowadays have a round-trip efficiency rating of at least 90%.

The EP900 has a continuous power output of 9 kW. The higher your battery's power output, the more of your home you'll be able to backup during an outage. The EP900 system has an impressively high power output.
