Connect with e-STORAGE experts and explore innovative turnkey energy storage solutions.
Built In-House
Every cell and every system is engineered and manufactured in-house, at gigawatt-hour scale in fully automated facilities, backed by 25 years of Canadian Solar manufacturing. One standard, start to finish.
One System, One Partner
Cells, power electronics, controls, EPC, and long-term service — most projects juggle a separate vendor for each. e-STORAGE brings them together as one system under one accountable partner, from the first cell to decades of dispatch.
System for Every Project
From the SolBank utility platform to the FlexBank solution-optimized line and the EQ-S energy management system, the portfolio spans hardware to controls — sized and configured to fit each project, not forced to fit a single box.
