What Is A 20000W Generator?
A 20000-watt generator is a robust machine that provides 20000 watts of electrical power, which is more than enough for a 3000-5000 square-foot apartment. With such a powerful machine, one can easily power a refrigerator, an air conditioner, an electric oven, a water heater, and several lights concurrently. With this many appliances running together, a 20000-watt generator becomes ideal for maintaining essential household or business operations during power outages or in remote locations.
There are different models of a 20000-watt generator and one can choose them as per their preference. The most common types are:
20000-watt portable generator: A 20000-watt portable generator is a high-capacity, movable power source that uses diesel or propane to perform. These generators are commonly used on construction sites, during outdoor events, or as emergency backup power. For instance, this diesel-run generator can run multiple high-demand appliances such as a refrigerator (700W), an air conditioner (2,000W), an electric oven (5,000W), and a water heater (4,500W watts).
20000-watt inverter generator: A 20000-watt inverter generator provides clean and stable power, making it ideal for those looking for alternatives to a traditional diesel generator. This generator converts AC power to DC and back to AC, which always ensures a reliable, consistent, and smooth power output for sensitive appliances like computers, medical devices, and entertainment systems.
20000-watt solar generator: A 20000-watt solar generator harnesses energy from the sun, converting it into electricity through solar panels and storing it in large batteries for later use. This eco-friendly and renewable power source is ideal for those who are aiming to reduce their overall dependency on the on-grid power supply. The complete independence from such grid power makes such generators ideal for off-grid living, camping, and emergency backup, especially in areas prone to power outages.
Before we learn more about the 20000-watt generator and evaluate which size is ideal for your household and outdoor needs, let us explain a couple of technical terms that will help you in this comprehensive guide.
Starting Wattage: Starting wattage is the initial burst of power that most appliances use when they are first turned on. For example, a central air conditioning unit might require around 15,000 watts to start, even though it runs continuously at about 5,000 watts. This high starting wattage is necessary to overcome the initial resistance, which ensures that the unit's compressor and fan motor are running.
Running Wattage: Running wattage is the amount of power an appliance needs to operate under normal conditions. In short, a running wattage is a continuous power that a generator must supply to ensure that the connected appliance is operational, even after the initial startup. For instance, a large electric furnace might require around 18,000 watts of running power to maintain heat in a large home.
Surge Wattage: Surge wattage refers to the short-term peak power an appliance needs for just a few seconds to start working effectively. This is especially common in appliances with motors or compressors. For example, a large industrial air compressor might have a surge wattage of 20000 watts to start, even though its running wattage is only around 12,000W.
Watt-Hours: A watt-hour (Wh) is a unit of energy that measures the amount of power consumed over time. For example, if an industrial heater uses 15,000 watts and runs for 2 hours, it consumes 30,000 watts or 30 kWh of energy. This measurement helps one easily understand the total energy usage and cost associated with running such heavy-duty appliances.
