16 kWh storage capacity for high energy demand

With a rated capacity of 314 Ah and a rated voltage of 51.2 V, the Deye SE-F16 Max-H provides a total of 16 kWh rated energy. The operating voltage range is between 44.8 and 57.6 V. This high storage capacity is particularly suitable for households with increased energy demand, for example due to a heat pump, electric vehicle or other high-power electrical consumers.

Integrated heating function for winter operation

A decisive advantage of the Deye SE-F16 Max-H is the integrated battery heating. While lithium batteries without a heating function should generally not be charged at temperatures below 0 °C, the heated H version enables charging at temperatures from -20 to +55 °C, provided that the heating function is active. This makes the SE-F16 Max-H particularly suitable for installation sites where low temperatures may occur in winter.

High charging and discharging power

The Deye SE-F16 Max-H is designed for demanding power requirements. The recommended charging and discharging current is 157 A in each case. During charging, up to 160 A continuously are possible, while the maximum continuous discharge current is 230 A. For short periods, the storage unit supports up to 280 A for 10 seconds both during charging and discharging. The maximum output power is 11.8 kW.

Safe LiFePO4 system with intelligent BMS

The Deye SE-F16 Max-H uses lithium iron phosphate cells, which are characterised by high thermal stability, safety and long service life. An integrated intelligent battery management system monitors operation and, together with an active fuse and the integrated circuit breaker, offers comprehensive protection for the battery system.

At least 8,000 charge cycles

Deye states for the SE-F16 Max-H a cycle life of at least 8,000 cycles at 25 °C ± 2 °C and 70 % residual capacity at end of life. In combination with a maximum DC roundtrip efficiency of 95 % and a stated energy throughput of 50 MWh, the storage unit is designed for long-term use in modern PV systems.

Modularly expandable up to 64 storage units

The modular storage concept enables flexible adaptation of the total capacity to the respective energy demand. As standard, up to 32 SE-F16 Max-H units can be operated in parallel. With a corresponding CAN bridge, according to the manufacturer up to 64 battery storage units connected in parallel are possible. This makes the SE-F16 Max-H suitable both for private systems and for more extensive storage solutions.

Automatic networking without DIP switches

The Deye battery modules support automatic networking. Manual addressing via DIP switches is therefore not required. This simplifies installation and configuration, particularly in storage systems with several battery modules operated in parallel.

Bluetooth app and Deye Cloud monitoring

The battery storage system supports local monitoring via Bluetooth Low Energy. This allows battery data to be retrieved directly via app without an internet connection being required. In combination with a compatible Deye inverter, the complete energy storage system can additionally be monitored remotely via the Deye Cloud. Supported are, among other things, real-time monitoring, intelligent charging and discharging strategies as well as remote upgrades.

Flexible wall and floor mounting

The flat housing design of the Deye SE-F16 Max-H supports both wall mounting and floor mounting. With dimensions of 464 × 914 × 244.5 mm, the storage unit can be installed in a space-saving manner despite its high capacity. The weight is approx. 118 kg.
