Generator Power for Lifestyle Blocks
Lifestyle blocks usually need a bigger generator than a same-sized house in town, because bore pumps, irrigation pumps and other motor-driven equipment draw a much higher starting current than lighting and appliances. As Riequip puts it plainly: "lifestyle blocks often require larger generators due to pumps and motor loads."
Get the pump and motor loads right first, then size everything else around them, rather than starting from a generic household kVA figure.
Who this guide is for
New lifestyle block owners
Working out backup power for the first time and not sure why "house-sized" generator advice doesn't quite fit.
Blocks with bore or irrigation pumps
Need to keep water supply running during an outage, not just lights and the fridge.
Blocks that already run a tractor
Weighing up a PTO generator against a standalone standby or portable unit.
Why lifestyle blocks are different
A typical house draws a fairly steady load: lights, a fridge, some power points, maybe a heat pump. A lifestyle block adds motor-driven equipment, most commonly a bore pump or pressure pump for water supply, and often irrigation or firefighting pumps as well. Riequip's own guidance is direct about this: "pumps and motors require extra starting power, so correct sizing is important." Motors can draw several times their normal running current for a second or two when they start, and a generator that isn't sized for that surge can fail to start the pump at all, even if it would run it comfortably once going.
This is why a lifestyle block often needs to size up from the kVA figure that would suit a similar-sized house in town, and why generic household sizing bands are a starting point here, not an answer.
What a generator can realistically run on a lifestyle block
| Load | Sizing consideration |
|---|---|
| Bore or pressure pump | Motor starting current is the main driver of generator size, not the pump's running wattage |
| Irrigation pump | Often runs alongside other loads; check whether it needs to start while other equipment is already running |
| Household essentials | Fridge, freezer, lighting and internet, per standard home backup sizing |
| Heat pump or hot water | Adds meaningfully to the load if you want more than essentials covered |
| Workshop tools or welders | Usually sized and run separately from house backup, closer to a trade generator setup |
Standby, solar autostart, or portable?
Standby or solar autostart
Starts automatically during an outage, which matters if a bore pump supplying household water needs to keep running whether or not anyone is home. Riequip's solar autostart backup range covers 3-12kVA.
Portable
Connected manually when needed. Suits a block where someone is usually around to set it up, and keeps upfront cost down.
PTO (tractor-driven)
If the block already runs a suitable tractor, a PTO generator avoids maintaining a second engine. Power is only available while the tractor is free to drive it, so it doesn't suit unattended backup during an outage.
Why this recommendation fits
The reason lifestyle blocks get their own sizing conversation, rather than just following home backup bands, comes down to motor loads. A generator rated for 6kVA of steady running power might only handle 4-5kVA of motor starting load without stalling, depending on the generator's surge capacity. Riequip's guidance on this is to size for the pump and motor loads specifically, then build the rest of the backup plan around that, rather than adding a pump onto a generator sized for the house alone.
When a lifestyle block doesn't need to size up
Not every lifestyle block has demanding motor loads. A block on town water supply with no irrigation pump, for example, may have a load profile close to an ordinary house and can follow standard home backup sizing. The extra sizing consideration in this guide applies specifically where bore pumps, irrigation, or other motor-driven equipment are part of the picture.
Limitations and alternatives
- Pump specifications vary widely. Starting current depends on the specific pump and motor, not just its running wattage. Confirm sizing with the generator calculator or a Riequip branch rather than estimating.

Frequently asked questions
- Why do lifestyle blocks need bigger generators than a typical house?
- Lifestyle blocks often run bore pumps, irrigation pumps, and other motor-driven equipment that draw a much higher surge current on startup than steady household appliances. A generator sized only for lighting and a fridge can fail to start a pump, so lifestyle block sizing needs to account for that starting load, not just the running load.
- What size generator do I need to run a bore pump or irrigation pump?
- It depends on the pump's motor size and starting current, which can be several times its running current. There is no single answer that fits every property; the safest approach is to check the pump's specifications and confirm sizing with the Riequip generator calculator or a branch, rather than estimating from kVA range alone.
- Should a lifestyle block use a standby generator or a portable one?
- A standby or solar autostart generator suits a lifestyle block that wants backup power to start automatically during an outage, particularly if pumps supplying household water need to keep running unattended. A portable generator suits a block where someone is usually on hand to connect it manually, and offers a lower upfront cost.
- Can a PTO generator work for a lifestyle block?
- Yes, if the block already runs a suitable tractor. A PTO generator has no engine of its own and draws power from the tractor's PTO shaft, so it avoids maintaining a second engine, but power is only available while the tractor is free to drive it. Riequip's PTO range runs from 16kVA to 93kVA.
