Solarmi masterunit Deye HVB750V/100A-EU, BMS controllbox for BOS-G, HV assemblies

Xtend Solarmi Deye HVB750V/100A-EU BMS control unit for high-voltage BOS-G battery systems with easy installation in a 19" rack. It has detailed management, high reliability and a built-in display. With its help, it is possible to create a battery cluster containing 3 to 12 batteries in series with a total capacity of up to 61.44 kWh. Protective functions include over-discharge, over-charge, over-current and too high/low temperature. The system can automatically control charging, monitor the discharge state and perform current and voltage compensation for each module individually. The package includes a power cable for connection to the first and last battery module. Key features of the BOS-G system: Standard & quick installation – BOS-G system elements are designed for installation in a 19" rack. Safe and reliable – The cathode material is made of LiFePO4 with safe performance and long service life. The module has a lower self-discharge rate (up to 6 months without charging), no memory effect and excellent shallow charge and discharge performance. Intelligent BMS (Battery Management System) – A system for automatically controlling charge/discharge status, equalization currents, etc. Scalability – Up to 12 units/batteries in series (capacity 61.44 kWh, usable energy capacity 55.29 kWh). Eco-friendly – The entire module is non-toxic, non-polluting and environmentally friendly. Flexible configuration – Multiple battery modules can be connected to expand capacity and performance. Support USB upgrade, Wi-Fi upgrade (optional), remote upgrade (compatible with Deye inverters). Wide temperature range – The operating temperature range is from -20 to +55 °C, with excellent discharge performance and service life. Thermal management – Temperature detection of key parts, cell, power plug-in, etc. Certification – Meets CE, IEC62619, UL1973, UL9540A, UN38.3 certifications and standards.
