GRW67P / FS3A Hybrid 30/24Li Hybrid Generator

Description

The Pramac GRW67P / FS3A Hybrid 30/24Li is a compact hybrid diesel generator and battery energy storage system designed to deliver reliable, efficient temporary power for applications with variable load demand. The unit integrates a 60 kVA Perkins diesel generator, a 30 kVA hybrid power module (bidirectional inverter), and a 24 kWh lithium-ion battery pack within a single sound-attenuated enclosure.

This hybrid architecture enables the generator to operate in multiple intelligent modes, allowing the system to power loads using batteries, the diesel engine, or a combination of both. By prioritising battery operation during low load conditions and engaging the diesel generator only when required, the GRW67P hybrid significantly reduces fuel consumption, noise emissions, and operating costs while maintaining high power availability.

The system is designed for demanding temporary power environments including construction sites, industrial operations, and event power, where load profiles fluctuate throughout the day. The integrated Hybrid Power Module (HPM) manages power conversion and synchronisation between the generator and battery storage, enabling seamless load sharing and peak-load support.

The lithium battery system provides 24 kWh of storage capacity with approximately 3000 cycles at 80 % depth of discharge, enabling extended battery-only operation and reduced generator runtime. During peak demand periods, the battery can provide boost power in conjunction with the generator, allowing the hybrid system to deliver up to 88 kVA (74.8 kW) of power.

The GRW67P hybrid generator is housed within a soundproof and weather-resistant enclosure, mounted on a heavy-duty fully bunded base frame incorporating the fuel tank and battery storage. The design includes forklift pockets, lifting points, and a comprehensive control panel with integrated Human-Machine Interface (HMI) for selecting operating modes and monitoring system performance.

Key operating modes include:
• Just Battery (JB) – battery-only power supply
• Just Engine (JE) – conventional diesel generator operation
• Eco Mode – automatic hybrid operation for maximum efficiency
• Full Mode – generator with battery boost capability
• Emergency Power Supply (EPS) – battery backup in case of generator failure
• Plug-in Recharge – external grid charging of the battery system (Optional Extra)

With its hybrid power architecture, the Pramac GRW67P provides an advanced mobile power solution capable of delivering high efficiency, lower emissions, reduced fuel consumption, and quieter operation, making it particularly suited to modern rental fleets and environmentally sensitive job sites.
