Measurements¶

The DER's live electrical measurements live in SunSpec Model 701 — active / reactive / apparent power per phase, voltage L-N and L-L, current per phase, frequency, power factor, and the cumulative energy registers (Wh and VARh, import and export).

These are the same values the dashboard's overview tile plots and the WebSocket telemetry stream broadcasts on every tick — Model 701 is the canonical wire shape, and every other view derives from it.

For the JSON nameplate fields that set the initial 701 values (so energy counters start from a non-zero baseline, useful for replay scenarios), see Simulation Inputs — JSON nameplate format.
