Quick Answer
For a 2,000 square foot house, an optimal generator size would be a 20-30 kW unit to provide sufficient power for essential appliances during a power outage.
Determining Generator Size
To determine the optimal generator size for your 2,000 square foot house, start by calculating your total power requirements. Consider essential appliances like refrigerators, air conditioners, and lighting, which typically consume around 5-10 kW of power. Add 10-20% to this total to account for additional loads like computers, televisions, and water pumps.
Generator Size Calculator
Use the following formula to calculate the required generator size: Total Power Requirements x 1.1 (for a 10% buffer) = Required Generator Size. For example, 10 kW (total power requirements) x 1.1 = 11 kW. Round up to the nearest whole number to ensure you have sufficient power. In this case, a 12-15 kW generator would be sufficient for a standard 2,000 square foot house.
Whole House Standby System
A whole house standby system is designed to automatically switch to generator power during a power outage, ensuring continuous operation of essential appliances. This system typically includes a transfer switch, which connects the generator to the electrical panel, and a control panel, which monitors the power supply and automatically switches to generator power when the grid supply fails. For a 2,000 square foot house, a 20-30 kW generator would provide sufficient power to support a whole house standby system.
