Canadian Solar’s energy storage division is launching a massive lithium battery system at RE+ next week. The FlexBank 1.0 is an 8.36-MWh scalable BESS from e-STORAGE. The new system is expected to be ready for deployment in 2026.
FlexBank 1.0’s modular open-frame architecture enables each cabinet to function as an independent building block, greatly simplifying logistics and installation. The FlexBank platform also serves as a foundation for e-STORAGE’s next-generation battery cell technologies that will feature higher amperage in a larger form factor and superior performance characteristics.
Built on e-STORAGE’s 314-Ah lithium-iron phosphate (LFP) cell technology, FlexBank 1.0 enhances safety through a multi-tiered protection system. Within each cabinet, cells are protected by heat barriers, a three-level electrical protection system, and advanced cell-level precision management. The modular design is engineered to prevent thermal propagation between cabinets, substantially mitigating fire risk. The datasheet lists the BESS length at 34.5 ft using five cabinets.
In addition, FlexBank 1.0’s skid-mounted design enables rapid on-site assembly and versatile layout configurations, including side-by-side and back-to-back installations. This flexibility reduces EPC costs while maximizing project energy density. The system is fully compatible with power conversion systems, ensuring seamless integration for both new deployments and site augmentations.
“FlexBank 1.0 is the strategic evolution of our utility-scale energy storage platform, engineered to address our customers’ critical needs for safe, adaptable, and cost-effective solutions,” said Colin Parkin, President of e-STORAGE. “By dramatically simplifying deployment, we are providing a more reliable and adaptable technology that will accelerate the global transition to renewable energy and deliver tangible value for developers and investors.”
