Deye SE-F16-C – Advanced energy storage system with 16 kWh (LiFePO4)

The Deye SE-F16 is a high-capacity low-voltage energy storage system (51.2 V) designed for demanding applications in domestic and commercial photovoltaic systems. With an enormous rated capacity of 16 kWh (314 Ah) in a single compact housing module, this storage unit significantly minimises space requirements and installation effort.

This model utilises the tried-and-tested, intrinsically safe lithium iron phosphate (LiFePO4) cell chemistry. Combined with the intelligent Battery Management System (BMS) and a wide range of monitoring options (including Bluetooth), the SE-F16 offers maximum safety, scalability and longevity for the self-sufficient energy supply of your home or business.

Highlights at a glance

• Massive storage capacity (16 kWh): With a rated capacity of 314 Ah at 51.2 V, this single module provides enough energy to reliably supply large households even during prolonged periods of low sunshine.
• Safe LiFePO4 cell chemistry: Lithium iron phosphate technology guarantees maximum thermal stability and virtually eliminates the risk of thermal runaway (fire hazard).
• High-performance 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 high-current, high-power consumers such as heat pumps or wallboxes.
• Extreme scalability: For even greater energy requirements, up to 32 units can be connected in parallel as standard. With a CAN bridge, it is even possible to scale up to 64 modules.
• Smart monitoring & connectivity: In addition to CAN 2.0 and RS485, the battery system features Bluetooth for convenient monitoring via a 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), ensuring decades of reliable operation in daily use.
• Flexible installation: Despite its heavy weight, the enclosure system is extremely flexible and can be installed either on the wall, floor-standing or stacked.

Areas of application

The Deye SE-F16 is the perfect solution for demanding energy scenarios:

• Detached and terraced houses: Maximises self-consumption of PV electricity and, in combination with a hybrid inverter, provides a powerful emergency power supply for the entire building.
• Commercial and industrial (C&I) applications: Used to shave off expensive peak loads (peak shaving) and store large surpluses of PV energy on agricultural or commercial premises.
• Off-grid & stand-alone systems: Thanks to its enormous capacity and high continuous discharge rate, it provides a reliable energy source for completely off-grid installations.

Installation & Safety Instructions

• Logistics and weight: Weighing 109 kg, the module is extremely heavy. It must be installed using suitable lifting equipment (a stair climber) or by at least two to three people.
• Choice of location: The battery 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-sectional area of at least 70 mm², or preferably 95 mm², to prevent overheating and voltage drops.
• Commissioning for parallel connection: If you are connecting several SE-F16 modules together, it is essential that all units are charged to exactly the same voltage level before cabling to prevent dangerous equalisation currents.

FAQs on the Deye SE-F16

What is the difference between the SE-F16 and the SE-F12?

The main difference lies in the capacity and the height of the housing. The SE-F16 delivers 16 kWh (314 Ah) and weighs around 109 kg, whilst the SE-F12 11.8 kWh (230 Ah) and weighs approx. 84 kg. Both use the same 51.2 V architecture and are designed for identical applications; however, the F16 offers significantly greater autonomy per installed module.

What does the ‘C’ in the model name SE-F16-C stand for?

The suffix “-C” on Deye batteries indicates the extended model variant, which, in addition to Bluetooth monitoring, features a built-in LCD display on the front of the housing. This allows the current state of charge (SoC), cell voltages and warning messages to be read directly on the device without having to open the app.

Do I absolutely need a Deye inverter for this battery?

No, but it is strongly recommended for trouble-free operation. The SE-F16 is ‘Plug & Play’ compatible with Deye low-voltage hybrid inverters (such as the SG04 series), as the BMS protocol is natively compatible. For third-party brands (such as Victron, SMA or Solis), communication must first be configured manually via DIP switches or software settings. It is strongly recommended that you check the compatibility list, as manufacturers may make changes.
