Discover AES LiFePO4 Lithium Battery Certified to UL9540 with Schneider Electric XW PRO Hybrid Inverter for Solar Energy Storage Systems

AES LiFePO4 Batteries certified UL 9540 for Solar Energy Storage Systems

Vancouver, BC, May 1, 2021Discover Battery (Richmond, BC) and Schneider Electric (Burnaby, BC) are pleased to announce the UL 9540 safety certification of Discover Battery’s Advanced Energy System (AES) LiFePO4 lithium battery and Schneider Electric’s XW Pro hybrid inverter. UL9540 certification simplifies the design and installation approval process for residential solar off-grid and whole-home backup energy storage systems to 20kWh.

Discover AES LiFePO4 lithium batteries feature a proprietary high current Battery Management System (BMS) with closed-loop communication and easily integrate with the XW Pro hybrid inverter. The battery’s internal BMS automatically sets and dynamically manages the XW Pro’s charge and discharge configuration, improving recharge time by up to 25% when compared with open-loop control. UL9540 approved designs with the XW Pro for both the AES LiFePO4 7.4kWh and 3.0kWh battery models provide installers with design flexibility and paralleling options to the 20kWh limit for a residential ESS.

Schneider Electric’s XW Pro is the heart of a great power conversion system, connecting solar with battery storage and the grid or a generator to deliver energy security. XW Pro provides design flexibility by matching energy storage with a broad range of power output requirements for demanding solar off-grid and whole-home backup applications. With the ability to select various battery capacities per inverter, installers can tailor system designs to client’s needs.

“Integrating AES LiFePO4 batteries with the XW Pro platform delivers best-in-class performance, real-time battery status, dynamic charging and data-logging for system owners,” said David Norman, VP Solar Sales, Discover Battery. “With UL9540 certification, North American installers can be confident that the pairing of XW Pro with Discover AES LiFePO4 batteries meets the highest safety standards. Furthermore, the permitting process should now be a smooth and routine matter with the local inspector and Authority Having Jurisdiction (AHJ).”

“Recently extreme weather has tested grid resiliency in North America, and as a result, we have seen solar + storage become increasingly popular with consumers,” noted Bernhard Kiechl, VP of Marketing, Research & Development, Schneider Electric Solar. “The XW Pro hybrid inverter with AES lithium batteries provides installers with a powerful UL 9540 safety-certified solar + storage package for quick installation and permit approval. At Schneider Electric Solar, we’re focused on providing safe and reliable solutions for homeowners and business owners by making system design and installation easy,”
