Choosing the Right Generator: A Comprehensive Guide

by | Jun 22, 2023 | Outdoor Generators

Power outages and the need for reliable power solutions are common occurrences. Whether it’s for emergency backup during blackouts or powering your outdoor activities and camping trips, choosing the right generator is crucial.

In this guide, we’ll walk you through the key considerations, types of generators suitable for different needs, and the essential features to look for when purchasing a generator.

Power Requirements Assessment

Before purchasing a generator, it’s essential to assess your power needs. Take into account the appliances, equipment, and electronics you want to power. Make a list of commonly used household and outdoor items and their corresponding power requirements. This assessment will help you determine the wattage and power output needed from your generator.

Types of Generators

Portable Generators

Portable generators are versatile and offer flexibility. They can be easily transported and provide power where you need it the most. Consider the fuel options available, such as petrol, diesel, or dual-fuel, and their pros and cons. Additionally, factors like power output, runtime, and noise levels should be considered when selecting a portable generator.

Inverter Generators

Inverter generators offer clean power output and fuel efficiency. They are particularly suitable for powering sensitive electronics and devices. Unlike traditional portable generators, inverter generators adjust the engine speed based on the required load, resulting in improved fuel efficiency and quieter operation.

Standby Generators

For homeowners seeking a permanent backup power solution, standby generators are the optimal solution. These generators are installed outside the house and provide seamless power during outages. They are equipped with an automatic transfer switch, which detects power loss and activates the generator. Consider installation requirements and engage a professional for a proper setup.

How to Ensure a Generator Meets Your Power Requirements

Determine your power needs

Start by assessing the electrical devices or systems you need to power during an outage or in a remote location. Make a list of the essential appliances, tools, or equipment, and note their power ratings in watts.

Calculate the starting and running power

Certain devices, like motors or compressors, require extra power during startup. Identify the devices that have a high starting surge and determine the additional power needed. Add this to the running power requirements of all the devices to get the total power needed.

Consider load management

If your total power requirements are significant, you may need to prioritise certain devices or implement load management strategies. This involves categorising devices into essential and non-essential loads and selectively powering them based on priority.

Determine power factor and efficiency

Consider the power factor and efficiency of the generator. The power factor refers to the ratio of true power (watts) to apparent power (volt-amperes). If your devices have a low power factor, you may need a larger generator to compensate for the reactive power.

Choose the generator size

Once you have the total power requirements, consider a generator that can handle the peak load comfortably. It’s recommended to have a generator with a capacity 20-25% higher than your calculated load to accommodate any additional power needs or future expansions.

Consider fuel type and runtime

Decide on the fuel type (gasoline, diesel, natural gas, propane) based on availability, cost, and convenience. Also, consider the generator’s runtime on a full tank of fuel to ensure it can provide power for the desired duration without frequent refuelling.

Seek professional advice

For complex power needs or critical applications, it’s advisable to consult with a qualified electrician or generator specialist who can evaluate your requirements and recommend the appropriate generator size.

Remember, choosing the right generator size is crucial to ensure reliable power supply without overloading the generator. It’s always better to err on the side of caution and select a slightly larger generator to avoid potential issues and ensure adequate power capacity.


Key Features and Considerations

When choosing a generator, there are several key features that need to be considered:

  • Wattage: Ensure the generator can handle your power requirements.
  • Starting Power: Some appliances and equipment require an extra surge of power during startup.
  • Fuel Capacity and Run Time: Consider the fuel capacity and how long the generator can run on a full tank.
  • Noise Levels: Generators can be noisy, so look for models with lower decibel ratings.
  • Portability: If you plan to move the generator frequently, consider its weight, size, and ease of transportation.
  • Ease of Use: Look for user-friendly controls and features that simplify operation.
  • Maintenance Requirements: Regular maintenance is necessary for optimal performance, so consider the maintenance tasks and frequency.
  • Safety Features: Look for generators with features like overload protection and automatic shutdown in case of low oil.

Fuel Considerations

The availability and accessibility of different fuel types should be considered when choosing a generator. Petrol and diesel are widely available options. Keep in mind the advantages and disadvantages of each fuel type, including cost, storage requirements, and safety precautions. Ensure proper fuel storage and adhere to safety guidelines to prevent accidents.

Budgeting and Cost Considerations

Generators come in various price ranges, and costs extend beyond the initial purchase. Consider factors like fuel consumption and maintenance requirements. While budget constraints are important, it’s crucial to strike a balance between affordability and long-term reliability. Opting for a reputable brand and model that suits your needs can save you money in the long run.

Maintenance and Care

To ensure your generator functions optimally, regular maintenance such as performing routine inspections, changing oil according to manufacturer recommendations, and storing the generator properly when not in use is recommended. Consider engaging local generator service providers that can assist with maintenance tasks and repairs.

Final Thoughts

Selecting the right generator is essential for meeting your specific power requirements. By assessing your needs, considering the different types of generators, evaluating key features, and factoring in budget and maintenance, you can make an informed decision. Remember, a reliable generator can provide peace of mind during power outages and enhance your outdoor experiences. Choose wisely and enjoy the benefits of uninterrupted power whenever and wherever you need it.
