Product Features

Highly-efficient & Performance-Driven: The ESU25 is chargeable through solar skid, grid or generator input and the 40kWh battery will recharge in 2 hours. Right-sized power eliminates the need to oversize generators—systems are aligned to actual load requirements. It operates only when needed, reducing wear and extending equipment life, while ensuring diesel generators run at optimal efficiency (typically 75% of peak output).
Rapid Deployment & Flexibility: Plug-and-play setup enables quick site deployment. The compact shape with forklift pockets, tie-downs, and lifting points allows safe and easy handling. Scalable architecture lets you link multiple units for megawatt-scale storage.
Enhanced Safety: The system monitors battery temperature, charge level, and charge rate to protect against short circuits and overcharging. Units utilise low-heat runaway lithium iron phosphate cells and incorporate three-level safety protection measures.
Smart features: Simple set up and operation suitable for non-technical users with optional remote monitoring. Live updates on battery state of charge, as well as battery health on local EMS.
Durable: The IP54 rated aluminium enclosure is designed to withstand harsh Australian weather conditions. Featuring intelligent air conditioning system (HVAC) to maintain optimal temperature and maximise life and reliability.
Zero Emissions:A true netZERO solution combining a battery energy storage with Fuelfix solar skid and cutting reliance on fossil fuel-based sources and ongoing operational costs. The long-lasting lithium ferrous phosphate (LiFePO4) battery technology produces zero noise and air pollution.
