SolBank 3.0 Plus is e-STORAGE's next technological advancement in its successful SolBank battery solutions product line offering. SolBank 3.0 Plus uses enhancements to the Lithium-Ion Phosphate (LFP) battery cell manufacturing processes to bring the battery performance to a new level over the already successful SolBank 3.0.

Canadian Solar Inc. (the "Company" or "Canadian Solar") (NASDAQ: CSIQ) today announced that e-STORAGE, which is part of the Company's majority-owned subsidiary CSI Solar Co., Ltd. ("CSI Solar"), will officially launch its SolBank 3.0 Plus battery energy storage product at Intersolar Europe.

SolBank 3.0 Plus is e-STORAGE's next technological advancement in its successful SolBank battery solutions product line offering. SolBank 3.0 Plus uses enhancements to the Lithium-Ion Phosphate (LFP) battery cell manufacturing processes to bring the battery performance to a new level over the already successful SolBank 3.0. In doing so, e-STORAGE can offer its customers a battery solution with a 25-year lifespan, a near zero battery degradation curve for the first four years, and up to 12,000 cycles at a 95% round-trip efficiency. SolBank 3.0 Plus can significantly reduce its customers' operational costs by boosting overall lifetime energy throughput by over 13%.

Additional enhanced product features of the SolBank 3.0 Plus include its aerospace grade heat-resistant separator and upgraded and electrical protection systems, providing further enhanced safety over its demonstrated high safety standard and track record. The optimized design of the battery cooling system can reduce auxiliary load power consumption by up to 30% while providing a reduced decibel noise output superior to its competitive products. SolBank 3.0 Plus also utilizes active balancing technology down to cell level for battery performance optimization, operational health and monitoring.

Colin Parkin, President of e-STORAGE, stated, "SolBank 3.0 Plus is perfectly designed for integration into e-STORAGE 'all-in-one' battery energy storage solution, offering our customers a new leading-edge in safety and performance, continuously increasing the value and reliability of their deployed assets. This new product launch marks a major milestone in e-STORAGE's commitment to innovation and excellence. With enhanced performance, safety, and operational efficiency, these innovations are designed to meet the growing needs of utility-scale energy storage projects worldwide and reaffirm Canadian Solar's leadership in the energy storage industry."

The SolBank 3.0 Plus will be showcased at Intersolar Europe from May 7 to 9 in Munich, Germany. Visit Canadian Solar's booth A2.380 to learn more.
