AES RACKMOUNT Energy Storage System is a rapidly installed energy storage system that is easy to configure for Residential Off-Grid Solar, Whole-Home Backup Power and Microgrids.

UL1973 certification and pending UL9540 DC - ESS certification enable permitting throughout North America. An industry-leading 10-year warranty and energy throughput performance guarantee delivers a strong ROI. AES RACKMOUNT also meets the requirements of the Electromagnetic Compatibility (EMC) Directive and complies with FCC standards.

Networking AES RACKMOUNT with the LYNK II Gateway enables plug-and-play closed-loop communication with industry-leading hybrid inverters and dramatically elevates charging performance.

In minutes, quickly stack mount up to six AES RACKMOUNT Battery Modules with the AES RACKMOUNT Quick Stack Rack and parallel up to six Battery modules with a single AES RACKMOUNT Battery Combiner.

Install AES RACKMOUNT Battery Modules outdoors with the AES RACKMOUNT 30 kWh Outdoor Enclosure. Parallel up to five Slimline Enclosures - 150 kWh.
