Welcome to greenSANE. We are a European BESS manufacturer providing high-quality custom energy storage solutions for industry, commercial clients, and off-grid projects. greenSANE is a Polish manufacturer of battery energy storage systems (BESS) – ranging from mobile units (NONgenerators®) and temporary infrastructure, to industrial-grade storage and solutions for homes and offices. We design them to deliver the ultimate goal: uninterrupted power supply and reduced downtime.

In practice, it’s not just about capacity and power – it’s about reliable, long-term performance. That’s why we offer local service support, a genuine manufacturer warranty, and systems built with European battery components.

Polish Manufacturer Clear accountability for system integrity and performance.
Local Service Faster response times and streamlined warranty support.
European Batteries Consistent quality and predictable long-term operation.
Short Lead Times Local production with rigorous pre-delivery quality control.

We engineer modular energy storage systems designed to operate:

  • standalone (off-grid)
  • integrated with renewable energy sources (RES)
  • connected to the power grid
  • combined with power generators for seamless backup power
