Overview

Lights on, fridge cold, business open

Outages from storms, line faults and maintenance happen. A properly sized and installed generator turns a crisis into a minor inconvenience.

We handle the complete job: load assessment, generator selection, concrete pad or mounting, fuel considerations, exhaust placement, transfer switch, wiring and commissioning. Then we keep it ready with scheduled servicing.

  • Correct sizing, neither underpowered nor wasteful
  • Transfer switches that prevent dangerous back-feed to JPS lines
  • Automatic start within seconds of an outage (ATS systems)
  • Service plans and 24/7 emergency repair

Repair & troubleshooting

Won't start, won't hold load, low voltage, controller faults. We diagnose and repair.

Servicing

Never back-feedPlugging a generator into a wall outlet ("suicide cord") can electrocute JPS line workers and destroy your appliances. Always use a proper transfer switch or interlock.

Safety & care

Generator best practices

Outdoors only

Exhaust contains carbon monoxide. Keep generators away from doors, windows and vents.

Exercise it monthly

Run under load for 20–30 minutes so it's ready when you need it.

Store fuel safely

Approved containers, away from heat. Use stabiliser for petrol.

Pre-hurricane check

Service, fill fuel and test before the season begins in June.

Battery health

Most standby no-starts are a weak battery. Replace every 2–3 years.

Don't overload

Stagger large loads. Start the AC after the fridge and pump settle.

2

Select & site

Choose the unit, fuel type and location for airflow, noise and access.

3

Install & connect

Pad, transfer switch, wiring, earthing and fuel/exhaust setup.

4

Simulated outage test, load test and owner training.

FAQ

Generator questions

What size generator do I need for my house?

Essentials (fridge, lights, fans, TV, pump) typically need 3–6 kW. Running one or two AC units pushes it to 8–15 kW. Whole-home standby with multiple ACs and a water heater can need 20 kW+. Try the calculator above, then we'll confirm.

Diesel, gasoline or LPG?

Diesel is durable and efficient for larger and commercial units. Gasoline suits small portables. LPG stores well long-term and burns cleaner. We'll recommend based on size, usage and fuel availability.

How often should a generator be serviced?

Typically every 100–250 run hours or at least once a year, whichever comes first, plus extra checks after long outages.

Do you repair generators you didn't install?

Yes. We service and repair most makes of portable and standby generators.
