The Deye Low Voltage (LV) 25kWh system is created by combining modular, cobalt-free Lithium Iron Phosphate (LiFePO4) battery packs in parallel. Because Deye’s low-voltage residential batteries typically come in 5.12kWh modules (such as the SE-G5.1 Pro or AI-W5.1), a 25kWh LV bank is built by wiring 5 modules together in a rack or stack.
