FAQs
What size generator do I need for my home?
The right generator size depends on what you want to power during an outage:
- Essentials only (fridge, freezer, lights, internet, water pump)
- Most of your home (heat pump, hot water, kitchen appliances)
- Whole house backup
As a general guide:
- 5–8kVA → Essentials only
- 10–15kVA → Most homes
- 20kVA+ → Full home backup including larger loads
Lifestyle blocks often require larger generators due to pumps and motor loads. Contact Riequip for help sizing the right generator for your needs.
Can a generator power my whole house?
Yes. A generator can power your whole house when it is correctly sized and installed with a mains changeover switch.
- Generator size matches your household load
- Automatic or manual changeover switch is installed
- Connection is completed safely by a qualified electrician
Without a proper setup, you may only be able to power selected appliances using extension leads.
Do generators turn on automatically when the power goes out?
Yes. Generators with an Automatic Transfer Switch (ATS) can automatically:
- Detect a power outage
- Start the generator
- Switch your home supply to generator power
- Turn off once mains power returns
Do I need an electrician to install a generator?
Yes. In New Zealand, a registered electrician is required when connecting a generator to your home.
- Install a changeover switch
- Connect the generator safely to your switchboard
- Ensure compliance with NZ electrical requirements
Diesel vs petrol generators – which is better?
For many NZ homes and lifestyle blocks:
Diesel generators:
- More fuel efficient
- Better for long outages
- Longer operating lifespan
- Ideal for standby systems
Petrol generators:
- Lower upfront cost
- Suitable for occasional portable use
- Easy to transport
How noisy are generators?
Noise depends on the generator type:
- Portable enclosed inverter generators → Quiet and suitable for residential use
- Open-type air cooled diesel generators → Louder and better suited for worksites
- Enclosed standby diesel generators → Quiet and designed for home backup
How much does a home generator cost in NZ?
Typical pricing ranges include:
- Portable generators → $1,000 – $5,000
- Small home backup systems → $5,000 – $10,000
- Full standby systems → $15,000 – $25,000+
Cost depends on generator size, automation, installation requirements, and system complexity.
What maintenance do generators require?
Regular maintenance helps keep your generator reliable:
- Annual servicing
- Oil and filter changes
- Battery checks
- Regular test runs
What can a generator run on a lifestyle block?
Generators can power common lifestyle block equipment including:
- Water pumps and bore pumps
- Septic systems
- Fridges and freezers
- Heat pumps
- Workshop tools
- Lights and power outlets
Pumps and motors require extra starting power, so correct sizing is important.
Can I plug a generator straight into my house?
No. Connecting a generator directly into household wiring without the correct equipment is unsafe and illegal.
A safe setup requires:
- A proper changeover switch
- A dedicated connection point
- Professional installation
Can generators handle NZ weather?
Yes. Enclosed standby generators are designed for outdoor conditions including:
- Rain protection
- Cold temperatures
- Outdoor installation
- Coastal environments with suitable setup
How long will a generator run?
Runtime depends on generator size, fuel capacity, and load:
- Portable generators → approximately 6–18 hours per tank
- Standby diesel generators → can run for days with suitable fuel storage
Should I get a generator or solar battery backup?
Generators:
- Works day or night
- Handles larger loads
- Lower upfront investment
Solar battery systems:
- Silent operation
- Renewable energy source
- No fuel required
Many NZ rural properties use both systems together for maximum reliability.
Are generators safe?
Yes, when installed and operated correctly.
- Never run portable generators indoors
- Use correct electrical connections
- Ensure proper ventilation
- Avoid DIY wiring
Can a generator run pumps and workshops?
Yes, but pumps, motors, and workshop equipment require higher starting power.
- Correct generator sizing
- Enough surge capacity
- Protection against overload

Choosing the right generator can be challenging, especially for homes with pumps, motors, or whole-house backup requirements.
