Description
A compact 51.2 V, 100 Ah LiFePO₄ pack built for residential and light-commercial ESS where safety, longevity, and clean inverter integration matter.
The SE-G5.1 Pro-B–class module uses cobalt-free LFP cells, an intelligent BMS, and a 19-inch rack form to keep installs tidy—wall, rack, or floor-stack. Auto-networking and CAN/RS-485 comms make multi-battery scaling straightforward, while front-access breaker/ports simplify commissioning and service.
Product Details
-
Safe, long-life chemistry: LFP cells with multi-thousand-cycle endurance and stable thermal behavior.
-
Smart BMS control: Cell balancing plus protections for over/under-voltage, over-current, and temperature; front DC breaker on many wall/floor variants.
-
ESS-ready communications: CAN / RS-485 handshakes with Deye hybrids and many third-party inverters.
-
Scalable architecture: Parallel up to dozens of modules (series supports up to 64) for larger backup panels and longer autonomy.
-
Installer-friendly: 19" rack footprint, front service ports/LEDs, labeled landings, and clear addressing for multi-pack stacks.
