AETERNA ⚡ ENERGY LAB — Skaly

A real house in the Czech countryside with a rooftop solar plant (FVE) and a battery behind a hybrid inverter is measured live by two three-phase meters. This is not a simulation — every number below is real electricity flowing right now. Read it, analyze it, predict it.

📖 How to read this data · Jak číst data

FVE (fotovoltaická elektrárna) = the photovoltaic solar plant. The meter measures the output of a hybrid inverter with a battery — solar generation and battery discharge combined. Solar peaks around midday; non-zero output at night = the battery discharging, not sunlight. Production is always shown as a positive number.

Grid import = the house buys electricity from the public grid (typically at night). Grid export = surplus solar is fed back to the grid (sunny days). The meter "house-main" sits at the grid connection point: positive power = import, negative = export.

Consumption = production + grid power. Example: FVE produces 7500 W, grid shows −6400 W (export) → the house itself uses 1100 W.

Self-consumption = the share of the hybrid inverter output (FVE + battery) used directly by the house instead of exported: (production − export) / production. Higher is economically better — self-consumed energy replaces expensive imports.

Phases L1/L2/L3 — Czech houses use three-phase 230/400 V supply; loads are split across three phases, each measured separately (power, voltage, current, power factor).

SolarEdge inverter (second source) — the inverter's own cloud telemetry is polled politely (max 1 request/min) and finally separates what the Shelly meter cannot: solar-only production, battery power (+discharge / −charge) and battery state of charge. Cross-check both sources at /comparison.
