Battery Hybrid – EPH 70-75

Manufacturer: Atlas Copco
Voltage: 240/120V • 60 Hz • Energy Storage: 76.8 kWh (71.4 kWh usable)

Overview

The Atlas Copco EPH 70-75 Hybrid Generator delivers silent, efficient, low-emission hybrid power by combining a Tier 4 Final diesel generator with a high-capacity Lithium Iron Phosphate (LiFePO₄) battery energy storage system (ESS). Engineered for rental, events, telecom, and remote-site operations, the EPH 70-75 supplies up to 9 hours of silent, battery-only power per charge and dramatically reduces diesel runtime, fuel consumption, and maintenance costs.

With built-in solar charging capability, intelligent energy optimization, and fully integrated telematics, the EPH 70-75 is one of the most advanced, sustainable hybrid power systems available for mobile and temporary power applications.
