United Rentals, Inc. announced that it will offer its customers zero-emission power systems with the introduction of POWRBANK battery systems in its rental fleet. The company's partnership with manufacturer POWR2 Energy Solutions represents a significant investment in sustainable worksite solutions for United Rentals customers in North America. The POWRBANK is a portable energy storage system that integrates with diesel generators, enabling the user to significantly reduce generator run-time and reduce emissions, noise and fuel waste.

The system is comprised of high-density lithium batteries, inverters and load-sensing technology. The POWRBANK model designed for United Rentals is rated for 40KW to 60KW of power output and provides between 60KW and 120KW hours of storage. POWRBANK inverters are pure sine wave and emission-free for completely clean energy.

The system is designed to absorb fluctuations in load while providing power; then engage the diesel generator when the batteries are close to depletion. The equipment is essentially maintenance-free, with a recharge time of three and four hours that can be reduced by adding renewable power sources, such as solar.
