Deye SE-F5 Pro-C – Advanced LiFePO4 storage system – 51.2V / 5.12 kWh
Description
Product information
The Deye SE-F5 Pro-C is a state-of-the-art 5.12 kWh battery storage module based on safe lithium iron phosphate technology (LiFePO4). As part of the "Pro" series, this 51.2V low-voltage battery has been specially developed for seamless integration with Deye hybrid inverters and other common 48V systems.
The storage unit is characterised by its high energy density, the cobalt-free chemistry and the intelligent battery management system (BMS). The SE-F5 Pro-C is the ideal solution for homes and commercial applications that require reliable self-consumption optimisation (solar) or robust emergency power supply. Thanks to its modular design, capacity can be flexibly expanded from 5 kWh up to high double-digit kWh.
Highlights at a glance
- Safest cell chemistry (LiFePO4): Uses lithium iron phosphate, which is extremely thermally stable, does not burn, and is considered the safest lithium technology on the market.
- High capacity (5.12 kWh): Offers 100 Ah at 51.2 V nominal voltage in a compact enclosure, ideal for long autonomy times.
- Long service life (6000+ cycles): Designed for over 6000 charge/discharge cycles (at 25°C, 90% DOD), which means a usage life of well over 10–15 years.
- Intelligent BMS: The integrated battery management system protects against overcharging, deep discharge, overcurrent and overtemperature and ensures active cell balancing.
- Environmentally friendly (Cobalt Free): The battery contains no toxic cobalt at all, minimising environmental impact during manufacturing and disposal.
- Flexible scalability: Supports the parallel connection of up to 32 units (for some modules even up to 64) to achieve storage sizes of over 160 kWh.
- Easy installation: Thanks to 19-inch standard dimensions, the module is ideal for rack systems or wall mounting (with suitable brackets).
- Deye compatibility: Perfectly matched to Deye hybrid inverters (automatic recognition via CAN bus), but also compatible with Victron, Growatt, SMA etc. (depending on protocol).
Areas of application
The Deye SE-F5 Pro-C is extremely versatile:
- Self-consumption optimisation: Storage of surplus PV electricity for the night.
- Emergency power systems (backup): Reliable energy source during power outages.
- Peak shaving: Limiting peak loads in commercial operations.
- Off-grid systems: Stand-alone systems without grid connection.
Technology & advantages
The SE-F5 Pro-C stands out thanks to the following technical features:
- LFP technology: Unlike NMC batteries, LiFePO4 does not tend towards "thermal runaway" if damaged. This makes installation in homes particularly safe.
- Smart communication: The BMS actively communicates with the inverter. It reports state of charge (SOC), state of health (SOH) and temperature in real time so that the inverter can dynamically adjust the charging curve.
- Soft-Start: Integrated precharge resistors prevent high inrush currents which could trip fuses when switching on the battery.
Installation & operating instructions
- Cabling: Standard battery cables (often 25mm² or 35mm²) with Amphenol or M-screw connections (please check for each model!) are required to connect to the inverter. The communication cable (RJ45, CAN-Bus) is mandatory for the warranty.
- Addressing: When connected in parallel, batteries often have to be addressed via DIP switches (Master/Slave configuration), the Master taking over communication with the inverter.
- Temperature: Lithium batteries should not be charged at temperatures below 0°C. The BMS stops charging in the event of frost to protect the cells. Ideal operating range: 15°C to 30°C.

FAQs about the Deye SE-F5 Pro-C
Does this battery also work with other inverters?
Yes. Deye uses standard protocols (Pylontech protocol etc.). The battery is compatible with many 48V low-voltage inverters (e.g. Victron Energy, Growatt, SMA Sunny Island, Solis) as long as the matching protocol is selected in the BMS or inverter. However, it delivers the best performance in the Deye ecosystem.
What is the difference to the SE-G5.1 Pro?
The designations (Pro, Pro-C, Pro-B) often refer to revisions in the chassis design, chip availability or certifications (e.g. UL certificates for specific markets). The key technical data (5.12 kWh, LFP) is usually the same. The "C" version is usually the latest, optimised for the European market.
Can I expand the battery later?
Yes, absolutely. You can always connect more modules in parallel to increase capacity. The BMS will balance charge differences between new and old modules to some extent. However, it is recommended to combine modules with a similar ageing state or to synchronise the system all at once.

The Deye SUN-6K-SG05LP1-EU is an ultra-modern and powerful single-phase hybrid inverter that acts as an intelligent control centre for larger photovoltaic systems. It has been developed to offer you maximum independence, efficiency and security of supply. With a high output power of 6 kW, it manages the energy flows between your solar modules, the battery storage system and the public grid. Thanks to its integrated emergency power function, you are reliably supplied with high power even in the event of a power failure.Highlights at a glanceIntelligent hybrid system: Manages PV generation, battery storage and grid consumption for maximum self-consumption.High performance: With 6 kW output power ideal for larger households, heat pumps or small commercial operations.Integrated emergency power supply: Provides an uninterruptible power supply (UPS level) in the event of a grid failure.Two MPP trackers: Enables the connection of two independent module arrays, ideal for east-west roofs or partial shading.Flexible battery connection: Compatible with a wide range of 48V low-voltage battery storage systems.Comprehensive monitoring: Integrated WLAN module for simple and intuitive system monitoring via app.Intelligent energy management for your homeThe Deye hybrid inverter is more than just a converter from direct current to alternating current. It is the brain of your energy supply. During the day, it supplies your consumers directly with solar power, while surplus energy is stored in your battery storage system for the night or for cloudy days. The energy is only fed into the public grid when the storage system is full and no consumer requires electricity. This maximises your self-consumption and significantly reduces your electricity costs.Maximum yields through flexible PV connectionThanks to the two integrated MPP trackers (Maximum Power Point), the Deye SUN-6K offers maximum flexibility when planning your PV system. You can connect two separate module strings with different orientations (e.g. east and west side of the roof) or with different module types. Each tracker optimises the output of its string individually so that you always achieve the maximum possible energy yield, even with complex roof situations or partial shading.Independence through integrated emergency power supplyA special feature of this inverter is the integrated emergency power function. If the public power grid fails, the device switches to a separate emergency power output in less than 10 milliseconds and continues to supply selected critical loads such as lighting, refrigerators or the IT infrastructure with power from the battery storage system. This switchover time to UPS level (uninterruptible power supply) ensures maximum security of supply.
