Cut Site OPEX with a Pramac Hybrid Package

Discover Pramac’s Smart Hybrid Power Solution for Construction Sites

Driven by a growing industry demand to couple power generators with battery energy storage systems to reduce fuel consumption and emissions, modern construction sites are rapidly rethinking their power strategies. The implementation of a Pramac hybrid ecosystem autonomously optimizes site energy, replacing inefficient idling with smart power management that drives unprecedented OPEX savings.

Construction sites typically rely on a single, oversized diesel generator sized to handle the heaviest daytime peaks. However, at night, when powering only welfare units, security cameras, or lighting, this massive machine is forced to run underloaded. This traditional setup wastes expensive fuel, accelerates engine wear, and needlessly drives up operating costs (OPEX) and emissions.

The game-changer for rental companies and contractors is transitioning to a hybrid power architecture. As a global manufacturer of power equipment, Pramac provides the ultimate turnkey solution: pairing a Pramac generator with a fully compatible, plug-and-play Pramac BESS. By integrating these technologies, site managers can significantly downsize their primary generator without sacrificing performance.

During low-load periods, the Pramac BESS takes over completely, supplying silent, zero-emission power while the generator is shut off. When sudden load peaks occur, both units work together to deliver the required energy. Available in a wide range of capacities, Pramac BESS units are designed to perfectly match any specific load profile.

Crucially, the hybrid operation is managed autonomously. The true “brain” of the system is the new, user-friendly DSE digital controller installed directly on the BESS. This smart module drives the entire system, offering two main operating strategies: ECO and FULL. In ECO mode, the BESS handles the site’s load, automatically starting the generator only for recharging or during massive power spikes. In FULL mode, the generator runs continuously at its most fuel-efficient point, while the BESS instantly intervenes to absorb power peaks, preventing genset overload.

For sites with evolving power needs, Pramac offers unmatched scalability. Thanks to the new Parallel Panel, multiple BESS units can be easily connected in parallel. This effectively creates a single, unified virtual battery with a total power output and energy capacity equal to the sum of the individual units, ensuring total flexibility for any project size.

To elevate this ecosystem, Pramac offers an invaluable extra tool: Pramac Link. This proprietary hardware and cloud-based software solution provides complete remote telemetry. Installed on both the generator and the BESS, Pramac Link allows operations managers to remotely monitor and control the performance of the entire hybrid system from anywhere.

With this all-in-one package, Pramac delivers a highly profitable energy solution. Rental companies can offer a premium, fully integrated product, while contractors benefit from minimized diesel consumption, drastically lower OPEX, and a greener worksite.
