The Deye BOS-A is a modular high-voltage energy storage module designed for use in powerful and scalable storage systems for residential and commercial applications. Based on superior lithium iron phosphate (LiFePO4) technology, each module offers a capacity of 7.68 kWh. Multiple modules are connected in series to form a high-voltage system that ensures maximum efficiency, safety and flexibility for modern photovoltaic systems.Highlights at a glanceScalable high-voltage system: Several modules (e.g. 7 to 21 units) are combined in series to form a powerful high-voltage storage tower.Maximum safety with LiFePO4: Cobalt-free lithium iron phosphate technology is considered to be the safest and most durable on the market.Intelligent battery management system (BMS): Each module is permanently monitored to ensure safe and optimised operation.High efficiency: The high-voltage technology reduces energy losses and increases the overall efficiency of the system.Professional rack mounting: Developed for simple and secure installation in standard industrial racks.Flexible scalability for high energy requirementsThe Deye BOS-A storage system is designed for maximum flexibility and future-proofing. Starting with a system size of seven modules (approx. 54 kWh), for example, the capacity can be adapted to growing energy requirements by adding further modules. This scalability makes the system the ideal solution for sophisticated homes with heat pumps and e-mobility as well as for agricultural and commercial operations that want to maximise their own consumption and reduce peak loads.Maximum safety and longevity with LiFePO4The use of lithium iron phosphate cells (LiFePO4) sets the highest safety standard in storage technology. These cells are extremely thermally stable, intrinsically safe and do not require the use of cobalt. They are characterised by an exceptionally high cycle stability of over 6000 charge and discharge cycles, which enables a very long service life of over 15 years and makes the system a sustainable and economical solution.Intelligent control and professional installationThe centrepiece of the system is the intelligent battery management system (BMS), which is bundled in a higher-level control unit (Cluster Control Box). It reliably protects the storage system against overcharging, deep discharge, overtemperature and short circuits. It also ensures active balancing of the cells, which maximises efficiency and service life. The individual modules are designed for quick and safe installation in professional racks (control cabinets), which ensures a clean and standard-compliant installation. Properties  ModelDeye BOS-A high-voltage storage module ApplicationHigh-voltage storage system TechnologyLithium iron phosphate (LiFePO4) Nominal voltage (V)38.4 Energy (kWh)7.68 Usable energy (kWh)6.91 Max. charge/discharge current (A)160 Cycle stability≥ 6000 (at 90% DOD) Dimensions (W x H x D in mm)approx. 450 x 550 x 150  H2: FAQs on the Deye BOS-A storage systemWhat is the advantage of a modular storage system?A modular system offers you the flexibility to start with a capacity that is customised to your current needs and to expand this later by adding further modules as required. You can adapt your storage system to an increasing energy demand, e.g. from an electric car.Why is LiFePO4 the safest lithium technology?LiFePO4 cells have a very stable chemical structure. They are not susceptible to thermal runaway, even in the event of mechanical damage or overcharging. This makes them the safest choice for use in residential and commercial buildings.What is the advantage of a high-voltage (HV) compared to a low-voltage (LV) storage system?A high-voltage system works with a higher voltage and correspondingly lower currents in order to transmit the same power. Lower currents lead to less heat loss in the cables and the inverter, which increases the overall efficiency of the system (PV system, storage system and inverter).Which inverters is this system compatible with?The Deye BOS-A system is optimised for the high-voltage hybrid inverters from Deye (e.g. 50-100 kW series). Communication between the BMS of the storage system and the inverter ensures perfectly coordinated and efficient operation. Compatibility with inverters from other manufacturers should be checked in advance. Scope of delivery: Deye BOS-A (7.68 kWh HV battery storage module) 1 x Deye BOS-A battery module (7.68 kWh)A powerful high-voltage LiFePO4 storage module for industrial applications with a capacity of 7.68 kWh, designed for installation in 19-inch rack systems.1 x set of internal DC connection cablesShort, high-current-resistant power cables for serial connection of the module to the next module within the battery cabinet.1 x internal communication cable (RJ45)A data cable for integrating the module into the internal BMS communication chain for monitoring cell voltages and temperatures.1 x mounting set (screws and mounting bracket)Special brackets and screws for secure mechanical fixing of the module in the profile rails of the rack.1 x earthing cable (grounding cable)A yellow-green cable for professional potential equalisation between the module housing and the central earthing point of the enclosure.1 x operating instructions (manual)A technical supplement with specifications, installation instructions and information on the correct addressing of the module in the system network.
