Determine AC Power Consumption: The power consumption of an AC unit is typically measured in British Thermal Units per hour (BTU/hr) or watts. If your AC unit provides the power consumption in BTU/hr, you can convert it to watts by using the following formula: 1 watt = 3.412 BTU/hr. For example, if your AC unit consumes 12,000 BTU/hr, it would require approximately 3,514 watts (12,000 / 3.412) to operate.
Account for Starting Surge: AC units often require extra power to start up compared to running continuously (starting surge). Consult the unit's specifications to determine the starting wattage, which can be significantly higher than the running wattage.
Total Power Consumption: Add up the power requirements of all essential appliances and systems, including the AC unit(s), to determine the total power consumption during an outage.
Generator Capacity: Choose a generator with a capacity that exceeds the total power consumption calculated in step 4. This ensures that the generator can handle the combined load, including any starting surges from the AC unit(s) and other appliances.
Consider Surge Capacity: Generators typically have a surge capacity, allowing them to handle temporary spikes in power demand when appliances start up simultaneously. Ensure the generator's surge capacity is sufficient to start all appliances, including the AC unit(s), without overloading the system.
Consult a Professional: For precise sizing and installation, consider consulting with a qualified electrician or generator specialist. They can assess your specific requirements and recommend the most suitable generator size for your home, taking into account factors such as AC power requirements, other appliance loads, and surge capacity.
In summary, determining the size of generator needed to run your house with AC involves calculating the power requirements of your AC unit(s) along with other essential appliances and systems. By carefully assessing your needs and considering factors such as starting surge and surge capacity, you can choose the right-sized generator to ensure uninterrupted power supply for your home during outages.
