US Energy Distributors Named Master Distributor and Primary U.S. Contact for UZ Energy

SES AI Corporation ("SES AI") (NYSE:SES), a global leader in the development and manufacturing of AI-enhanced high-performance Li-Metal and Li-ion batteries, today announced that UZ Energy, an SES AI company, has become a Sol-Ark® certified battery partner and has named US Energy Distributors as the master distributor for UZ Energy’s battery products in the United States.

With this certification, UZ Energy is positioned to compete for battery sales within an established market from the outset and to capture market share as Sol-Ark installers, distributors, and customers evaluate new certified energy-storage configurations.

"Expanding UZ Energy’s presence in the United States is an important part of SES AI’s energy storage strategy," said Dr. Qichao Hu, SES AI founder and CEO. "Certification with Sol-Ark connects UZ Energy to a large and established residential energy storage ecosystem and creates an immediate path to compete for U.S. battery sales. This certification also provides installers and distribution partners access to a broader range of integrated storage configurations while supporting the continued commercial growth of the UZ Energy platform."

UZ Energy will be listed under Sol-Ark® low voltage (48V) certified battery partners. UZ Energy’s three low-voltage residential batteries are certified for closed-loop compatibility with the Sol-Ark 12K-2P-LL, 15K-2P and 18K-2P Hybrid Inverters. The certification combines Sol-Ark’s hybrid inverter technology and established installer ecosystem with UZ Energy’s lithium iron phosphate battery systems, creating additional residential energy-storage configurations for installers, distributors and homeowners across the United States.

Sol-Ark has established a substantial U.S. residential energy-storage ecosystem spanning its hybrid inverters, certified battery partners, distributors and installer network. The certified UZ Energy residential battery portfolio includes: UZ Energy L051100-B 5.12kWh Power Lite Series; UZ Energy PLPA-L1-10K2-U Power Lite Plus Series; and UZ Energy IG-16K-U 16kWh Power Lite Plus Series.
