Many people estimate power usage by guesswork, then wonder why inverter and battery sizing feels wrong. The fix is simple: count real equipment usage by room and convert watts to kilowatt-hours using actual run-time.
Start with active equipment only. For each device, multiply wattage by quantity and average daily operating hours. Sum these values across all rooms to get daily watt-hours, then divide by 1,000 for daily kWh.
This approach aligns with the EnergiX stage flow because it captures usage behavior, not only the list of appliances. That makes cost estimates and package recommendations more reliable.
