Passaggi

  1. 1List major loads with power level and hours per day or per interval.
  2. 2Separate continuous, intermittent, and seasonal loads so you do not double count.
  3. 3Compute daily energy and peak demand for inverter and cable screening.
  4. 4Document uncertainty bands where habits or occupancy drive variance.
  5. 5Refine with metering data as soon as a logger is available.

Esempi

  • Small business with daytime HVAC and evening lighting peaks.
  • Weekend-only cabin loads vs weekday standby draws.

Cosa evitare

  • Using nameplate appliance power without duty cycle.
  • Forgetting standby and parasitic loads that dominate off-grid nights.
  • Mixing monthly bills with instantaneous peak assumptions without reconciliation.

FAQ

Is one day enough?

For screening yes; for storage ROI you often need seasonal or weekly patterns.

Motor starting?

This guide covers steady profiles; inrush needs separate motor starting review.
