Applications

PQpluS is a versatile Battery Energy Storage System (BESS) designed to optimise energy use, enhance grid stability, and support the transition to cleaner power. Its key applications include:

• Peak Shaving: Reduces energy costs by discharging stored power during peak demand periods, helping avoid utility penalties and ensuring a more balanced load profile.

• Time-of-Use Optimisation: Enables users to store energy from RES or the grid during off-peak hours and use it during expensive peak times, without changing consumption habits.

• Renewable Integration: Acts as a buffer for intermittent sources like solar and wind, storing excess energy and releasing it when generation drops, thus stabilising the grid.

• EV Charging Support: Powers fast EV chargers in remote or grid-constrained areas, reducing the need for costly grid upgrades.

• Black-Start Capability: Restores power independently after outages, supporting grid recovery and enhancing energy resilience.

• Seamless Grid Transitions: Smoothly switches between grid-tied and off-grid modes (and back), maintaining a power supply and improving waveform quality

• Reliable maintenance and support throughout the entire product lifetime
• The modular, scalable and type-tested design of pre-engineered building blocks, reduces engineering and commissioning time
• Compact design that requires a small footprint, ideal for applications where space is at a premium
• UL9540A-tested Lithium-ion NMC batteries and modularized, high-efficiency, power conversion solution offering best-in-class safety and performance
• Can connect to any third-party controller and Energy Management System (EMS)
