What Size Diesel Generator do I Need for Backup? 

Reliable portable generators work to provide you with all the electrical energy you need to keep your home or business running smoothly. To ensure that you get the most out of your generator investment, it is important to consider certain factors which will ensure that your generator unit is the right fit for your requirements. Read on for expert tips from Diesel Generation Australia on how to make the right choice. 

Choosing the Right Generator Size 

Before investing in a generator, we recommend following these steps so you can make in informed decision: 

Hire a Professional Electrician 

Your first step should be to hire an experienced, certified electrician who can conduct a thorough inspection of your electrical system and accurately estimate the maximum power load of your location. 

Determine Your Requirement 

Begin by making a thorough list of the appliances you want to run using back up power. This should include all critical equipment and lighting for a commercial space and important household appliances such as back up refrigerators and lighting for homes. Record the starting wattage and running wattage for each appliance (usually included on the information plate fixed to each device). 

To make things easier, convert all the numbers into kW of KVA. Multiplying the amperage by Voltage will give you the wattage for resistive load. Multiplying amps by volts and multiplying that result by the load factor, will yield the reactive load wattage. Do not hesitate to hire a professional who can assist you with these calculations if required as they are critical to the decision making process.

Choosing Generator Size 

Running a diesel generator at its maximum capacity for long periods results in the system becoming inefficient in time. This can cause damage to critical components, which may require frequent replacement and also drive up fuel consumption and cost. We recommend selecting a generator with a total output which is at least 10% higher than your maximum power requirement. 

This will prevent overloading of the generator, improve fuel efficiency, reduce maintenance cost, improve safety and allow you to add more equipment to your backup system if required.
