The Ultimate Resilience: Designed for the Real World

 

What truly sets the Prostar PET+Li Series apart is its ability to operate flawlessly in the most challenging and unpredictable power environments. It is not designed for a perfect world; it is engineered for the real world, where power grids are unstable, generators are a necessity, and equipment demands are unforgiving. This is the defining characteristic of a true Lithium-ion UPS for home or small business, where reliability is non-negotiable.

 

🌍

Ultra-Wide Input & Generator Compatibility

110-300VAC Input Range: This is the cornerstone of its resilience. Unlike conventional UPS systems that fail or shut down during brownouts or surges, the PET+Li Series can handle a massive 110-300VAC input range. This means it can operate seamlessly on unstable grids, in remote locations, or during severe voltage fluctuations without switching to battery mode unnecessarily, thereby preserving battery life.
Generator Ready: The system’s wide input range and frequency adaptability (50/60Hz) make it perfectly compatible with generators. It can accept the often unstable and distorted power output from a generator, clean it, and deliver pure, stable sine wave power to your critical equipment. This is essential for businesses and homes that rely on generators as a primary or backup power source.

 

Application & Solutions: Where the Prostar PET+Li Series Shines

 

The Prostar PET+Li Series is not a one-size-fits-all solution; it is a precision instrument designed for specific, high-stakes applications. Its combination of safety, longevity, and resilience makes it the ideal choice for environments where power quality and uptime are paramount. This is the definitive Single Phase Lithium UPS for a new generation of critical infrastructure.

 

Server Rooms & Data Centers
