CAT Microgrid Master Controller

Caterpillar has expanded its power generation offering into renewable energy. The company has developed a strategic partnership with First Solar to create an integrated photovoltaic (PV) solar solution for microgrid applications, which are used in various applications.

The Cat renewable energy system is powered by thin-film solar panels, with performance efficiencies over other types of solar panels. The thin-film technology has a lower temperature derate ratio, so installed in an application where the operating temperature is greater than 30°C, the panel operates more efficiently than other solar options. A key component in the Cat Hybrid Microgrid system is the Cat Bi-directional Power Inverter (BDP).

The BDP inverter includes the robust Cat power electronics system. This is known for its operational capabilities, having been used in the Caterpillar D7e hybrid tractor, and ideal for the harsh Australian climate.

The energy storage technology includes lithium ion and the revolutionary zinc metal-air energy storage system. This storage system is one of the lowest cost electricity storage options available. The system includes standard integrated controls and battery monitoring at the cell level. A fully flexible offering enables a combination of these two technologies, while Catepillar’s engineers design the energy storage system according to the needs of the business.

Ron Hall, Segment Manager, Hybrid Microgrid Systems from Energy Power Systems Australia (EPSA) says Caterpillar and EPSA recognise the need to live in a sustainable manner with our environment.

“This new product range is the culmination of millions of dollars in research and development over several years. It combines high performance, project integration and after sales service with state of the art renewable power and the revolutionary Cat energy storage system.”
