What Size Generator Do I Need Calculator: Essential Inputs and Process
Initial Data Requirement
To effectively use a "what size generator do I need" calculator, begin by listing all the devices and appliances you intend to power. This involves determining both the number and type of items you'll be connecting to the generator.
Calculating Power Needs
The calculator requires input about the starting and running watts for each device. These power requirements are often found on device labels or in the user manuals. For total power requirement calculations, sum up the starting and running wattage of all devices. This figure will guide you to the appropriate generator capacity that meets or exceeds your needs.
Usage of kW and kVA Measurements
Understand that generators are often rated in kilovolt-amperes (kVA), which considers the efficiency and power factor of the generator. Given that most power factors used are approximately 0.8, convert the required watts (kW) to kVA using this factor for accurate generator sizing.
Additional Considerations
Account for the location and environmental conditions where the generator will be used, as this might influence the size due to factors like cooling needs and access for maintenance. Additionally, plan for the generator to operate at 70-80% of its maximum capacity if used as a primary power source, ensuring durability and efficiency.
Professional Assistance
To guarantee precision in calculating your specific needs and evaluating site conditions, consulting with a certified electrician is advisable. They can provide professional insights and ensure that your setup adheres to safety regulations and standards.
What Size Generator Do I Need Calculator Guide
When selecting the appropriate generator for your needs, using a "What Size Generator Do I Need Calculator" provides a precise and efficient way to calculate the ideal size. This type of calculator simplifies the process by allowing users to input the appliances and devices they intend to power.
Step-by-Step Calculation Process
Begin by listing all the appliances and systems you need to operate during a power outage. Include both essential items and comfort devices. After compiling your list, determine the starting and running wattage for each item, important for capturing the initial power surge and ongoing consumption.
Enter these values into the generator size calculator, which aggregates the total running watts. To ensure reliability and prevent overloading, the calculated size should include a 20% safety margin above the total wattage requirement. This margin compensates for unexpected increases in load or additional future appliances.
Understanding Capacity and Safety Margins
Choosing a generator that operates comfortably within its capacity is crucial for long-term durability and efficiency. Select a generator that utilizes no more than 90% of its total capacity under load. This practice not only extends the lifespan of the generator but also accommodates slight miscalculations in load estimations and future additions.
Special Considerations for Commercial Settings
In commercial environments, consider peak usage times and potential expansion. Measure the total amps using a clamp-on ammeter, or refer to historical data if available. Additionally, factors like non-linear loads, which are common in commercial settings, require specific attention as they affect the harmonic balance and can lead to undersizing if not properly accounted for.
This calculator approach simplifies the complex task of generator sizing, making it accessible even to individuals without technical expertise. However, for new constructions or highly specialized environments, consulting with a qualified engineer is advisable to account for variables that typical calculators might not cover.

Examples of Calculating Generator Size
Example 1: Residential Use
To determine the correct generator size for typical residential use, calculate the total wattage of essential home appliances. For instance, sum up the starting watts of a refrigerator (1200 watts), an oven (2150 watts), and an air conditioner (3300 watts). The required generator size is the sum, which equals 6650 watts. Therefore, a generator with a capacity of at least 7000 watts is appropriate.
Example 2: Small Business
A small business might need to power computers, lights, and a copier during an outage. To calculate: five computers (200 watts each), 10 light bulbs (60 watts each), and a copier (900 watts). Total = 2900 watts. A 3000-watt generator would suffice, but for additional capacity, a 3500-watt model is recommended to accommodate peak usage moments.
Example 3: Construction Site
For calculating the generator size required at a construction site, consider heavy-duty power tools like a concrete mixer and a chainsaw. A concrete mixer uses about 2500 watts, and a chainsaw about 1500 watts. Cumulative wattage stands at 4000 watts. A generator offering 4500 watts will cover these needs effectively, with a buffer for additional equipment.
Example 4: Outdoor Event
If planning a small outdoor event, calculate the power for lighting, audio systems, and food service equipment. Assume 500 watts for lighting, 600 watts for the sound system, and 2500 watts for catering equipment. Total energy need equals 3600 watts. Opt for a generator with at least 4000 watts to ensure smooth operation through the event.
Example 5: Camping Trip
For a camping trip, essential items might include a small fridge (700 watts), portable heater (1500 watts), and lights (200 watts). Total power required is 2400 watts. A compact 2500-watt generator provides sufficient power, with a small buffer for additional small appliances or charging devices.
