Deye BOS-G Pro Pack 5.1 \u2013 scalable high-voltage LiFePO4 energy storage module<\/h2>\n

The Deye BOS-G Pro Pack 5.1<\/strong> is a 5.12 kWh high-voltage LiFePO4 energy storage module<\/strong> that serves as the foundation of the modular Deye BOS-G Pro system. Thanks to its rack-mountable 19″ design and series expandability, the BOS-G Pro Pack 5.1<\/strong> modules enable the construction of a precisely sized high-voltage energy bank for any project \u2013 from 25.6 kWh up to 87 kWh<\/strong> \u2013 ideal for both demanding residential and commercial installations. <\/p>\n

Why choose the Deye BOS-G Pro Pack 5.1 energy storage system?<\/h3>\n

The Deye BOS-G Pro Pack 5.1 battery<\/strong> is based on proven LiFePO4 (lithium iron phosphate) cell chemistry, which offers a high level of safety, long cycle life, and extremely low self-discharge \u2013 it can be stored for up to 6 months without charging, with no memory effect. The system’s intelligent BMS independently manages charging and discharging states, balances current and voltage across individual cells, and provides protection against deep discharge, overcharging, overcurrent, and extremely high and low temperatures. The modular design allows you to flexibly expand capacity and power by connecting multiple modules in series. <\/p>\n
