AES RACKMOUNT 48-48-5120-H (Product Model 900-0067)

The AES RACKMOUNT ESS Battery Module performs reliably, installs quickly and configures easily for Off-Grid Solar, Whole- Home Backup Power and Microgrids. A high-current fourth- generation Battery Management System (BMS) reliably delivers high current and peak power to low-voltage hybrid inverters. Network RACKMOUNT Battery Modules in closed-loop communication to dramatically elevate inverter battery charging performance. Parallel unlimited kWh in open-loop or up to 180 kWh in a closed-loop system. Self-heating enables performance in cold climate applications. The optional RACKMOUNT Slimline Enclosure with RACKMOUNT Battery Modules installed is UL9540 DC ESS certified
