Discover The Power Of Cat® Hybrid Microgrid System.

Powering sustainable Progress. Everywhere. All The Time.


Caterpillar is leading the integration of renewable power with smart energy storage and conventional diesel or gas-fuelled power generation. As global fuel prices fluctuate and renewable technologies become increasingly more sophisticated. the Cat® Hybrid Microgrid System delivers a fully customisable and scalable hybrid power solution to meet your power needs today and for future expansions.


•Significantly reduce your fuel expenses

•Decrease harmful emissions

•Lower your total cost of ownership

•Achive favorable payback periods

•Experience clean, cost-effective electricity


The Cat® Hybrid Microgrid System


•Increased energy efficiency with no reliance on the grid and optimal total cost of ownership

•Efficient power that can be produced where and when it is needed without transmission lines and transformer losses

•High performance, scalable system designed and built using standardised building blocks that are easy and quick to install even in challenging environments.













Introducing The Cat® Grid Stability Modules


The Cat® grid stability modules are robust and scalable, energy storage systems. Each module integrates with renewable sources to provide short duration power when that source is not available. They also provide temporary backup power in the event of a power outage.




•Two Systems

Energy Time Shift Module (ETSM) and Grid Stability Module (GSM)

•Reliable and Scalable

Each system comprises a pre-engineered container easily installed on-site. Multiple energy storage modules can be operated in parallel for increased power output and/or to increase the battery kWh capacity.

•Grid Stabilization

Each system protects against many typical power problems, including power failure, voltage sags/surges, and under/over voltage conditions.

•BDP Bi-Directional Power Inverts

Cat® Bi-Directional Power (BDP) inverts provide exceptional reliability and durability and feature intelligent controls for the charging and discharging of the energy storage equipment. They also include static VAR compensator, full four-quadrant output power factor control, automatic anti-islanding, and are parallel ready (multiple modules may be used in parallel to increase total output).

•Australia-wide and Worldwide Product Support

Cat® dealers provide extensive post-sale support including maintenance and repair agreements from over 1,800 dealer branch stores operating in 200 countries, with over 200 Cat® dealer locations across Australia.


Standard Equipment
