The Deye SE-F16 is a high-capacity low-voltage energy storage system (51.2 V) designed for demanding private and commercial photovoltaic applications. With an enormous nominal capacity of 16 kWh (314 Ah) in just a single compact case module, this storage unit significantly minimises space requirements and installation effort.This model uses proven and intrinsically safe lithium iron phosphate (LiFePO4) cell chemistry. In combination with the intelligent battery management system (BMS) and extensive monitoring options (including Bluetooth), the SE-F16 offers maximum safety, scalability and longevity for autonomous energy supply to your home or business.Highlights at a GlanceMassive storage capacity (16 kWh): With 314 Ah nominal capacity at 51.2 V, this single module provides enough energy to reliably supply large households even during longer sunless periods.Safe LiFePO4 cell chemistry: The lithium iron phosphate technology guarantees maximum thermal stability and almost completely eliminates the risk of thermal runaway (fire hazard).Powerful power handling: The system supports an enormous continuous discharge current of up to 230 A and peak currents of 280 A (for 10 seconds), ideal for power-hungry large consumers such as heat pumps or wallboxes.Extreme scalability: Up to 32 units can be connected in parallel as standard for even greater energy needs. With a CAN bridge, scaling up to 64 modules is possible.Smart monitoring & connectivity: In addition to CAN2.0 and RS485, the storage unit features Bluetooth for convenient monitoring via smartphone app. The "C" version (SE-F16-C) also has an integrated LCD display.Durability & efficiency: Certified for over 6,000 charge cycles (at 25°C), which ensures reliable operation for decades in daily use.Flexible installation: Despite the high weight, the case system is extremely flexible and can be installed on the wall, floor-standing, or stacked.Areas of ApplicationThe Deye SE-F16 is the perfect solution for demanding energy scenarios:Single-family and multi-family homes: Maximises the self-consumption of PV electricity and, in combination with a hybrid inverter, provides powerful emergency power for the entire building.Commercial applications (C&I): Used to cap expensive load peaks (peak shaving) and store large PV surpluses in agricultural or commercial operations.Off-grid & island systems: Thanks to its gigantic capacity and high continuous discharge performance, provides a reliable energy source for totally off-grid properties.Installation & Safety InstructionsLogistics and weight: At 109 kg, the module is extremely heavy. Transport must always be carried out with suitable lifting equipment (stair climber) or by at least two to three people.Choice of site: The storage unit must be installed in a dry and ideally frost-free room (protection class IP21). Charging at temperatures below 0°C is automatically blocked by the BMS to protect the cells.Cable cross-sections: Due to the extremely high currents (up to 230 A continuous load), the connection cables to the inverter or busbar must have a cross-section of at least 70 mm², preferably 95 mm², to avoid overheating and voltage losses.Commissioning with parallel connection: When connecting several SE-F16 modules together, all units must be charged to exactly the same voltage level prior to cabling in order to avoid dangerous equalisation currents. Features  ModelDeye SE-F16 (Series C with display) Technology**LiFePO4** (lithium iron phosphate) Nominal voltage**51.2 V** (operating range: 44.8 V - 57.6 V) Nominal capacity**314 Ah** Nominal energy**16.0 kWh** Max. continuous current**230 A** (peak current 280 A for 10s) Cycle life**≥ 6000 cycles** (at 90% DOD and 25°C) CommunicationCAN 2.0 / RS485 / Bluetooth + App (incl.

The SE-F16 delivers 16 kWh (314 Ah) and weighs around 109 kg, while the SE-F12 offers 11.8 kWh (230 Ah) and weighs about 84 kg. Both use the same 51.2 V architecture and are designed for identical applications, but the F16 provides significantly more autonomy per installed module.What does the "C" stand for in the model name SE-F16-C?The suffix "-C" in Deye storage refers to the extended model variant, which, in addition to Bluetooth monitoring, is also equipped with an integrated LCD display on the front of the case. This allows the current state of charge (SoC), cell voltages, and warnings to be read directly on the device without having to open the app.Do I necessarily need a Deye inverter for this battery?No, but it is strongly recommended for smooth operation. The SE-F16 is "plug & play" compatible with Deye low-voltage hybrid inverters (such as the SG04 series), since the BMS protocol matches natively. For third-party brands (such as Victron, SMA, or Solis), communication must first be configured manually using DIP switches or software settings.

This makes the system suitable for long-term use with consistently high performance and reliability.Which inverters is the 10 kWh package compatible with?The system is officially approved for Deye hybrid inverters in the low-voltage series. The communication and operating parameters are matched to each other at the factory. “Plug-&-play” operation is possible without further configuration. A comparison with the compatibility list is recommended.Can I also operate the storage system with other inverters?There is no official approval from Deye for other inverters. Use with third-party devices is therefore at your own risk and without any guarantee of functionality.Does the battery need to be fully charged before initial commissioning?Yes, the manual recommends an initial charge to 100 % to ensure correct synchronisation of the state of charge (SoC). If this step is skipped, deviations in the SoC values and inaccurate capacity display may occur. If solar energy is not sufficient for the first full charge, the storage system can also be charged via the grid. Scope of delivery Deye AI-W5.1-B modular low-voltage battery system (10.24 kWh): System compositionThis product is a set and consists of three separate main components, which together form a 10.24 kWh tower system.Component 1: Deye AI-W5.1-B-BMS (control unit & base)The central control unit (BMS Cluster) that manages the entire system.

The only important thing is a location with free air circulation, as recommended in the manual. Additional air conditioning is not required.Does the battery need to be fully charged before initial commissioning?Yes, the initial charge to 100 % is necessary to ensure correct SoC detection (State of Charge). If this step is omitted, deviations in capacity display and charging behaviour may occur. For this reason, always fully charge the storage system first before you begin discharging it.How loud is the battery during operation?The battery operates completely without active fans and is therefore virtually silent. Only during switching do relays switch briefly, which can be heard for a short time.
