Atlas Copco’s Modular Hybrid Generators Target Lower Fuel Use and Smarter Jobsite Power
Atlas Copco recently announced its EPH series of modular hybrid generators, designed to cut fuel consumption and maintenance costs on jobsites. The system combines a Stage V diesel generator with a ZBP battery energy storage system inside a durable frame. It can also connect to solar panels or limited grid power. The controller prioritizes battery use for low and moderate loads, starting the diesel only for peaks or to recharge the batteries. This reduces idle time, noise and unnecessary wear. For contractors, the result is quieter, cleaner and more efficient power. The company estimates up to 90 percent less fuel use and up to 86 percent fewer CO₂ emissions compared to a diesel-only setup. With fewer engine hours, fleets can also expect reduced service needs and lower overall costs.
Benefits at a Glance
- Plug-and-play sockets for fast connection to gensets, loads or renewablesere EPH Fits
- Up to 90% less fuel use on variable loads
- Up to 46,000 euros in annual savings during continuous operation
- Up to 86% less CO₂ output compared to a diesel-only setup
- Up to 95% fewer engine hours, cutting service and maintenance
How It Works On Site
The battery bank carries low and medium loads, running silent for noise-sensitive jobs. When demand spikes or the charge drops, the generator starts, covering peaks and recharging the pack. This hybrid approach keeps the engine out of inefficient low-load operation, which reduces fuel waste and wet stacking. Contractors can scale power by adding storage or synchronizing multiple units. Options such as solar panel inputs and cold-weather kits broaden its application for remote or extreme environments. Plus, with the integrated ECO Controller, Atlas Copco’s advanced Energy Management System (EMS) — multiple units can be synchronized to increase total power output and adapt seamlessly to fluctuating energy demands
Specs Snapshot
The first two models in the range:
- EPH 80: 78 kVA hybrid output at 25°C, 40 kWh battery capacity, 92-liter fuel tank, 3 x 2.44 x 2.4 m footprint
- EPH 100: 100 kVA hybrid output at 25°C, 60 kWh battery capacity, 220-liter fuel tank, 4.5 x 2.44 x 2.4 m footprint
Both use lithium iron phosphate (LiFePO₄) packs with discharge depths up to 95% and recharge times under three hours.
Hybrid Power in Context
Atlas Copco’s modular hybrids arrive as the generator market shifts toward battery and hybrid solutions. Contractors are under pressure to cut noise, emissions and fuel costs. Hybrid generators provide flexibility by integrating renewable energy sources and battery storage with conventional diesel. They are proving useful on jobsites with fluctuating loads, events with noise restrictions and remote sites where fuel delivery is difficult.
