The Deye SE-G5.1 Pro-B is a state-of-the-art 51.2 V Lithium Iron Phosphate (LFP) battery that sets the standard for safety, reliability and flexibility in residential and commercial energy storage. Equipped with an intelligent BMS, cobalt-free LFP cells and a fully modular design, it delivers an impressive 5.12 kWh (100 Ah), supports up to 64 units in parallel (327 kWh total) and offers true 1C performance with 100 A continuous and 150 A peak current. Its ultra-compact 3U format (only 133 mm high) allows rack, wall or floor mounting and fits perfectly into 19-inch cabinets. Auto-networking, remote firmware updates via USB and comprehensive certifications (including IEC62619, UL1973, UL9540A and VDE2510-50) make the SE-G5.1 Pro-B the first choice for installers and end customers across Europe.
