Module capacity
Fixed 5.12kWh LiFePO4 module
Each rack module is a complete 5.12kWh / 100Ah energy block. Larger systems are built by paralleling identical modules.
Voltage architecture
51.2V operating window
Charge, operating, and cut-off voltages for inverter and UPS matching.
Stack / parallel configuration
From one rack module to 15 in parallel
Start with a single module, expand as a parallel bank, and scale to the documented maximum of 15 modules.
Schematic only — not product photography. Final parallel count is confirmed against inverter/UPS limits and site wiring.
Communication
Front-panel protocol ports
Documented communication interfaces on the module faceplate.
