Engineering Note & Sizing Guidelines:
- Surge Load: Equipment with electric motors (Refrigerators, Air Conditioners, Water Pumps) require 2x to 4x their rated power during initial startup.
- Generator Rating: Calculated using standard 0.8 Power Factor (PF) with safety buffers to allow continuous operation under 80% total generator load capacity.
- Solar System: PV panel estimation incorporates an estimated 25% overall system inefficiency (inverter losses, heat, wiring losses).
