Twin HAC20K-20 Hybrid generators, paired with mobile Solar Skids, powering a large site compound around the clock.

Product2x HAC20K-20 Hybrid + 4x Solar Skids

Project Length18 months monitored (547 days)

ApplicationPortable site offices power for a large compound

01Problem

Powering site offices 24/7 needed a cheaper, lower-maintenance alternative to diesel

High diesel reliance. Conventional generators had to run continuously to power a large compound of site offices.
Maintenance-heavy. Constant runtime drove up service costs and shortened engine life.
Large power demand. Site buildings and loads — lighting, kitchen equipment, workstations, air-con — needed a heavy-duty solution.
The brief: a more cost-efficient, lower-maintenance power solution for round-the-clock site power.

02Solution

Twin HAC20K-20 Hybrid generators, paired with four mobile Solar Skids

Solar takes the load. Four 1.8kWp mobile Solar Skids charge the units' 48V DC lithium batteries.
Diesel only tops up. Twin HAC20k-20 units, 15kVA continuous inverter output each, run only when needed.
Smart control. Real-time monitoring and 4G connectivity for remote oversight.
Built to last. Hot-dip galvanised Solar Skid frames, adjustable 0–45°, for long-term deployment.

03The Benefit

18 months, measured against a conventional 25kVA diesel genset

“The Hybrid system manufactured by Globe Power and supplied by Generators Australia, not only saved us large quantities of fuel, it greatly reduced construction noise on site as the generators only ran for 1-2hrs per day, some days even less. Compare that to a standard traditional generator that would have run 24/7 for the entire scope supporting our day shift and night shift staff on site. Power generation capabilities far exceeded our expectations with no power supply issues throughout the duration.”
