Choosing the Right Generator to Power Your Air Conditioner During a Blackout

When the power goes out during the hot summer months, having a generator ready to power your air conditioner can make all the difference. However, it's essential to choose the right size generator to ensure your AC runs efficiently and safely. This guide will help you determine the appropriate generator size and wattage for your air conditioner.

Understanding Generator Wattage

Generators are measured in watts, with two key values: starting watts and continuous watts. Starting watts refer to the initial power required to start the AC, while continuous watts represent the power needed to keep it running once started.

Typical AC Requirements

A 10,000 BTU window air conditioner typically requires a 2200 starting watt capacity generator and only 1500 continuous watts. This means you need a generator that can handle the initial start-up spike in power and then maintain a steady supply for continuous operation. A 2000 watt portable generator generally has the necessary starting capacity to run a 10,000 BTU air conditioner during a summer blackout.

Generator Specifications and Safety

The most critical line on your generator specification sheet is the Input Range Watts. This indicates the minimum and maximum wattage your generator can supply. For a 10,000 BTU air conditioner, you need a generator that can provide at least 1140 watts continuously, with a recommendation to size the generator 25 watts higher than the minimum requirement to ensure reliable performance.

Handling the Load and Starting Current

It's important to note that the generator must be able to handle both the AC's electrical load and the starting inrush of current required to kick-start the unit. While it may be tempting to run your AC during a blackout, it's important to balance comfort and environmental impact. Instead of relying on a generator, consider alternative cooling methods such as spraying water on your face or sitting with your feet in cool water.

Conclusion

When choosing a generator to power your air conditioner during a blackout, it's crucial to select one that can accommodate the starting and continuous wattage requirements of your AC. With proper wattage and safety in mind, you can enjoy cool air even during unexpected power outages without the need for excessive energy usage. Remember to always follow the manufacturer's guidelines and safety protocols to ensure a smooth operation of your generator in critical situations.
