Model: SE-G5.1 Pro-B – 5.12 kWh Low-Voltage LiFePO₄ Battery
Why You’ll Like It
• Old-school reliability, new-school tech. LiFePO₄ chemistry (zero cobalt) means rock-solid safety and a 20-year service life if you cycle once a day.
• Stacks like plywood. One pack holds 5.12 kWh; bolt up to 64 packs on the same CAN/RS-485 loop for a giant 327 kWh bank—no DIP-switch puzzle.
• Built to shrug off tropical heat. Charges from 0 °C and keeps discharging down to –20 °C; happy all the way up to 55 °C with only natural convection cooling.
• Three mounting options included. Rack-mount (3 U, 19-inch), wall-mount, or floor-stack—brackets and power/comms looms ship in the box.
