In plain language

When comparing Battery power rating, keep the unit, time period, measurement boundary, and underlying assumptions the same on both sides.

What it is not

It is not energy capacity and a high power rating does not establish how long a load can be served.

Decision context

Why it matters

Continuous and short-duration ratings, inverter limits, temperature, state of charge, phase configuration, and supported load characteristics must be separated.
