- 1List major loads with power level and hours per day or per interval.
- 2Separate continuous, intermittent, and seasonal loads so you do not double count.
- 3Compute daily energy and peak demand for inverter and cable screening.
- 4Document uncertainty bands where habits or occupancy drive variance.
- 5Refine with metering data as soon as a logger is available.
Exemplos
- Small business with daytime HVAC and evening lighting peaks.
- Weekend-only cabin loads vs weekday standby draws.
O que evitar
- 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.
