GT Power 9000ESi Inverter Generator – A Power Backup Solution

When the lights go out or you’re working off grid, reliable backup power matters.

The GT Power GT9000ESi 9000W Electric Start Inverter Generator is one of New Zealand’s top choices for homeowners, tradies, and event organisers who need serious, clean power.

This Generator Isn’t Your Average Portable Unit. 

With 9,000W (11.5 kVA) max output and around 8,200W continuous, it can comfortably run fridges, pumps and power tools at the same time. Thanks to its pure sinewave inverter, it delivers stable electricity that’s safe for sensitive electronics.

In real world use, the GT9000ESi delivers smooth, consistent power. Its inverter system keeps voltage stable under heavy load, perfect for homes, food trucks and mobile workshops.

It’s quieter than many open frame generators, the sleek casing helps reduce noise and vibration making it refined enough for residential use.

Great fuel efficiency, utilising Smart Throttle you can expect about 6-7 hours of runtime at 75-80% load. 

Maintenance is simple: regular oil checks and standard 4 stroke servicing will keep it running for years.

At around 95 kg, it’s not feather light, but the built in wheels and handles make it manageable

Key Features

Powerdyne 4 Stroke OHV Engine - With electric & remote start.

Large 27 Litre Fuel Tank - Upto 11 hours runtime @ 50% load.

Noise Level - Approx. 69dBA @ 50% load.

Two Wire Connection - ideal for home backup or solar integration

Who It Suits

Perfect for NZ homeowners wanting reliable backup, tradies needing onsite power, or event crews who can’t risk power drops.

For light use, a smaller inverter generator may make more sense, but for heavy-duty reliability, this one leads the pack.

Peace Of Mind

The GT Power 9000W Inverter Generator is a powerhouse built for dependability. It’s quiet, efficient, and ready for modern homes and worksites. 

While it’s not the cheapest or lightest, it offers something far more valuable
