ELEMENT ESS Battery Modules are manufactured with the highest-grade cobalt-free LiFePO4 cells for reliability and long life. Discover's GEN-4, high-current BMS delivers superior peak power for demanding loads and lightning-fast 1C charge and discharge rates. ELEMENT ESS Battery Modules are available with an optional BMS-managed heat mat that allows for operation in cold climates.

UL9540A testing and the pending certification of the ELEMENT ESS Battery Module to UL1973 and UL9540-BESS ensure simple permitting throughout North America. 10-year warranty plus an energy throughput performance guarantee supports the ELEMENT ESS Battery Module.

ELEMENT ESS Battery Modules are a plug-and-play integration with LYNK II Gateway that enables closed-loop communication and dramatically elevates charging performance with industry-leading hybrid inverters. Relays on LYNK II Gateway can trigger the start of a generator in response to closed-loop communication with ELEMENT ESS Battery Modules.

Parallel up to 30 kWh of ELEMENT ESS Battery Modules with an ELEMENT ESS Battery Combiner and host all of them in a single ELEMENT ESS Enclosure. Parallel and monitor up to four enclosures - 120 kWh - with an ELEMENT ESS Enclosure Combiner.
