Industrial & Portable Generators
164 generators from Atlas Copco, Honda, Briggs & Stratton (Vanguard + PowerSmart + QuietPower) and Hyundai. Portable inverter generators for sensitive electronics, petrol portable generators for site power up to 7 kVA, diesel industrial generators for fixed installation and commercial standby use, and high-kVA standby diesel for 22+ kVA continuous operation.
kVA sizing - continuous AND surge. Every generator size decision needs two numbers: continuous load (kVA / kW the gear pulls during normal use) and surge load (start-up peak when motors and compressors kick in). Surge can be 3-7 times continuous on motor-load gear (compressors, welders, big saws, water pumps). Undersized generators trip on surge; oversized run inefficiently and burn fuel at low load. Spec BOTH numbers before quoting.
Petrol portable - Honda GH + Vanguard. Honda GH series (GH5000 6 kVA, GH7000 7 kVA) are the contractor-grade petrol portable standard - Honda OHV engine, reliability proven across decades, parts and service Australia-wide. Vanguard (Briggs & Stratton heavy-duty) covers the same range with the Vanguard 6.5 HP, 9 HP and larger engines. Both are pull-start, AVR voltage regulation, standard 240V outlets + auxiliary 32A on the bigger units. Suit construction, agriculture, mining, mobile trade work.
Inverter petrol - Briggs PowerSmart + QuietPower + Atlas Copco P. Inverter generators output clean sine-wave power suitable for sensitive electronics (computers, control gear, medical equipment, audio). Briggs PowerSmart (P2400 2.4 kVA, P3400 3.4 kVA, P4500 4.5 kVA) and QuietPower Q6500 (6.5 kVA) cover the AU range. Atlas Copco P2000i + P3500i are the commercial-tier inverter range. Quieter than open-frame petrol generators (typically 50-60 dB vs 70-75 dB), more efficient at part-load (engine RPM tracks load instead of fixed 3,000 RPM).
Diesel industrial - Hyundai DHY + commercial standby. Hyundai DHY industrial standby generators (DHY22KSE 22 kVA + larger) cover fixed-installation and commercial standby use. Diesel-engine drive, AVR voltage regulation, sound-attenuated canopy, fuel tank for 8-24 hour continuous operation, ATS-compatible (Auto Transfer Switch). Right pick for commercial site backup, telecoms standby, medical facility power, food processing continuity.
Petrol vs diesel - cost per kWh. Petrol generators are cheaper at capex; diesel is cheaper at running cost per kWh on continuous load. Crossover point is typically 100-300 hours per year of continuous use - below that, petrol is cost-effective; above, diesel pays back. Diesel also has longer engine service life (~10,000+ hours vs petrol ~3-5,000 hours) and better fuel efficiency at heavy load. Match by expected annual use hours.
