Optimized for Your Energy Needs
Long-Lasting Energy Supply
With 241 kWh capacity and ≥8,000 cycles, the system delivers stable power for years of operation. You benefit from longer service life and lower battery replacement costs.
Lower Operating Costs
Optimized energy management and peak shaving reduce energy waste and electricity expenses. You benefit from more predictable and lower long-term operating costs.
Compact and Space-Saving Design
With a compact footprint and integrated design, the system fits easily into space-limited locations while still delivering high power output.
Stable, Grid-Friendly Power Output
The 125 kW PCS with Virtual Synchronous Generator (VSG) function improves voltage and frequency stability. This ensures smooth operation for sensitive equipment and better compatibility with weak or micro grids.
Flexible Mobile Deployment
The trailer-mounted structure allows quick installation and smooth relocation. You can easily move power between job sites, events, construction areas, or emergency locations without building fixed infrastructure.
Safe and Controlled Operation
Advanced battery management, controlled current limits, and integrated protection systems ensure safe charging and discharging. This reduces operational risk and lowers maintenance effort.

FAQ
Q: How long can the 241kWh system run my equipment off-grid?
A: It depends on your load. At the full 120kW output, it provides ~2 hours of continuous power. For a typical construction site or event (avg. 20-30kW), it can last 8-10 hours. The integrated 125kW PCS supports grid or generator input. Solar can be integrated through an external PV inverter to extend runtime.
Q: Is the trailer-mounted BESS safe for highway transportation?
A: Absolutely. Polinovel uses a heavy-duty dual-axle chassis with mechanical braking and all-terrain tires. Internally, the battery modules are protected by vibration-dampening brackets specifically designed to withstand road shocks and off-road conditions.
Q: How many EVs can this mobile station charge in a single deployment?
A: With 241kWh capacity, the system can provide a "top-up" (40-50kWh) for 4 to 6 electric vehicles. Its 120kW high-power output supports DC Fast Charging, making it the perfect mobile rescue asset for charging operators.
Q: What are the fuel-saving benefits compared to a diesel generator?
A: By switching from diesel to our BESS, users typically see a 30%–60% reduction in total operating costs. It eliminates idle fuel consumption and noise. With 8,000+ cycle life, the ROI is significantly higher than any combustion-based generator over its 10+ year lifespan.
Q: Can the system withstand extreme desert heat or arctic cold?
A: Yes. The system is IP54 rated and features an industrial-grade thermal management system (HVAC). This ensures the LFP cells stay within their optimal temperature zone even when outside temperatures range from -30°C to 60°C.
