Bidirectional UPS
Bidirectional UPS is critical for protecting sensitive and high-value loads such as data centers, medical equipment, and industrial systems with embedded PLC control. By continuously supplying clean power to the load—whether or not the external power feed is available—an online UPS isolates the load from grid outages, voltage fluctuations, and frequency deviations.
What Makes Bidirectional UPS Different?
LFP Online UPS delivers the highest level of power protection, supplying clean and consistent electricity without interruption. Unlike traditional lead-acid UPS systems, LFP technology offers a higher charge/discharge rate and at least twice the lifespan, delivering greater value for the same investment. The combination of advanced online topology and lithium performance sets a new benchmark for next-generation UPS solutions—and this is where we excel.

FFD Power’s Online UPS package is designed to:
Ensure a clean, continuous power supply, fully isolated from grid fluctuations and blackouts
Integrate renewables, storage, and diesel generation for maximum resilience
Deliver stable power while optimizing energy use through advanced EMS control
Up to 500 kW UPS Capability
The system utilizes four parallel 125 kW UPS cabinets, providing a total capacity of up to 500 kW. Each cabinet integrates a rectifier and inverter for seamless energy conversion. Its modular design allows flexible capacity expansion to meet future demand.
Zero-Millisecond Transfer Between On-Grid and Off-Grid
Built on an online UPS topology, the system continuously powers the load without any transfer delay. This ensures uninterrupted supply for critical equipment, protecting sensitive devices from all types of power disturbances.
Clean Output Isolated from Grid Disturbances
The UPS delivers stable, high-quality power output that is fully isolated from grid voltage fluctuations, frequency deviations, and harmonics.
Renewable Integration and Diesel Backup
The system supports PV integration to supplement power with renewable energy. Diesel generators can also replace grid input when needed, creating a highly resilient power architecture for continuous supply.
Smart EMS
A smart Energy Management System (EMS) manages power sources and load transitions in real time. It also optimizes PV energy utilization for maximum efficiency and reliability.
