Frequently Asked Questions – Generators NZ

What size generator do I need for my home?

Most homes require a generator between 3000W and 5000W to run essential appliances such as fridges, lights, and small electronics. Larger homes or additional appliances may require higher output.

What is the difference between inverter and standard generators?

Inverter generators produce cleaner, more stable power, making them safe for sensitive electronics like laptops and TVs. They are also quieter and more fuel-efficient than traditional generators.

Are portable generators suitable for worksite use?

Yes, many portable generators in NZ are designed for trade and worksite use. However, for heavy-duty tools and long run times, a larger generator may be more suitable.

Do Donovan’s Trade Supplies deliver generators across New Zealand?

Yes. While based in Whangarei, Northland, Donovan’s supplies generators NZ-wide, ensuring fast and reliable delivery.

Can a generator run a whole house?

Larger generators (typically 7000W+) can run most household systems, but it depends on total power demand. For full-home backup, a higher-capacity generator is recommended.

Are generators safe to use at home?

Yes, when used correctly. Generators should always be operated outdoors in well-ventilated areas to prevent carbon monoxide buildup. Always follow manufacturer safety guidelines.

What fuel do generators use?

Most generators run on petrol, although some larger or industrial models may use diesel. Fuel type depends on the generator model and intended use.
