Prostar E+Li series single phase lithium UPS represents the evolution of critical power protection, engineered for mission-critical applications requiring uncompromising reliability. This next-generation platform integrates lithium-ion technology with true online double-conversion topology, delivering superior power quality and resilience. Advanced DSP digital control and IGBT SVPWM modulation ensure precise management of utility/battery hybrid input, while proprietary BMS safeguards against thermal risks and optimizes cell longevity through real-time voltage/current/temperature monitoring. Designed for weak grids and high-impact loads, its 3x fast-charge capability minimizes downtime, and ECO mode achieves 98% efficiency. The solution further enhances operational continuity with parallel redundancy support and comprehensive remote monitoring via multi-protocol interfaces (RS485/CAN/SNMP/WiFi).

Lithium-ion Battery Technology
Lithium-ion technology is revolutionizing UPS batteries. Compared to traditional valve-regulated lead-acid (VRLA) batteries, Prostar Lithium-Ion batteries offer significantly higher power density, up to three times longer lifespan, faster recharge times, and can withstand up to ten times more discharge cycles. They come with a standard 5-year warranty, providing more than double the useful life and significantly extended runtime.
