FAQ
 

What are the advantages of using 314Ah high-capacity cells?

The 314Ah cells offer higher energy density and improved consistency compared to standard 280Ah cells. Fewer cells in series/parallel means higher system reliability and more efficient energy conversion.

 

 

 

Is this BESS rated for outdoor installation?

Yes, the cabinet is IP55 rated (equivalent to NEMA 3R), providing robust protection against dust, rain, and corrosion. It is designed for direct outdoor placement, saving you expensive indoor floor space.

 

 

 

Can it be integrated with my existing Solar PV array?

Yes. The system is designed for easy AC-coupled integration with existing PV systems. It allows you to capture excess solar energy during the day and use it whenever demand peaks.

 

 

 

Does the system support integration with Diesel Generators?

Yes. Our EMS can intelligently coordinate between the grid, solar, BESS, and backup generators to ensure 24/7 power resilience and optimize fuel consumption.
