Deye SUN-3.6K-SG05LP1-EU-AM2 - 3.6 kW low-voltage hybrid inverter

The Deye SE-F5 Pro-C is a state-of-the-art 5.12 kWh battery storage module based on safe lithium iron phosphate (LiFePO4) technology. 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 residential and commercial applications requiring reliable optimisation of self-consumption (solar) or a robust emergency power supply. Thanks to its modular design, the capacity can be flexibly expanded from 5 kWh up to the high double-digit kWh range.Highlights at a glanceSafest 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): Provides 100 Ah at a nominal voltage of 51.2 V in a compact housing, ideal for long operating times.Long service life (6000+ cycles): Designed for over 6000 charge/discharge cycles (at 25°C, 90% DOD), which corresponds to a service 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 absolutely no toxic cobalt, which minimises the environmental impact during both manufacture and disposal.Flexible scalability: Supports the parallel connection of up to 32 units (up to 64 in some cases, depending on the module) to achieve storage capacities of over 160 kWh.Easy installation: Thanks to its standard 19-inch dimensions, the module is perfectly suited for rack systems or wall mounting (with suitable brackets).Deye compatibility: Perfectly matched to Deye hybrid inverters (automatic detection via CAN bus), but also compatible with Victron, Growatt, SMA etc. (depending on protocol).Areas of applicationThe Deye SE-F5 Pro-C is highly versatile:Optimisation of self-consumption: Storage of surplus PV electricity for use at night.Emergency power systems (backup): A reliable power source in the event of a power cut.Peak Shaving: Peak load shedding in commercial premises.Off-grid systems: Stand-alone systems without a grid connection.Technology & BenefitsThe SE-F5 Pro-C stands out thanks to the following technical features:LFP technology: Unlike NMC batteries, LiFePO4 does not tend to experience "thermal runaway" if damaged. This makes installation in the home 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, enabling the inverter to dynamically adjust the charging curve.Soft start: Integrated pre-charge resistors prevent high inrush currents that could trip fuses when the battery is switched on. Installation & operating instructionsCabling: Standard battery cables (often 25mm² or 35mm²) with Amphenol or M-type screw terminals (check depending on model!) are required for connection to the inverter. The communication cable (RJ45, CAN bus) is essential for the warranty.Addressing: When connected in parallel, the batteries often need to be addressed via DIP switches (master/slave configuration), with the master handling communication with the inverter.Temperature: Lithium batteries should not be charged at temperatures below 0°C. The BMS stops charging in frosty conditions to protect the cells. Ideal operating range: 15°C to 30°C. Features ModelDeye SE-F5 Pro-C (Cobalt Free) Technology**LiFePO4** (lithium iron phosphate) Rated voltage**51.2 V** Rated capacity**100 Ah** Energy content**5.12 kWh** Recommended depth of discharge (DOD)90% (for maximum service life) Cycle life**≥ 6000 cycles** (at 25°C, 0.5C rate) CommunicationCAN 2.0 / RS485 (Perfectly matched to Deye inverters) Dimensions (W x D x H in mm)440 x 530 x 133 (standard **3U** rack height) Weight (kg)approx. **45.0 kg**  FAQs on the Deye SE-F5 Pro-CDoes this battery also work with other inverters?Yes. Deye uses standard protocols (Pylontech protocol, among others). The battery is compatible with many 48V low-voltage inverters, provided the relevant protocol is selected in the BMS or inverter. However, it offers the best performance within the Deye ecosystem. It is strongly recommended that you check the compatibility list beforehand.What is the difference compared to the SE-G5.1 Pro?The designations (Pro, Pro-C, Pro-B) often refer to revisions in the casing design, chip availability or certifications (e.g. UL certificates for specific markets). The core technical specifications (5.12 kWh, LFP) are usually identical. The "C" version is often the current variant, optimised for the European market.Can I expand the battery later?Yes, no problem. You can connect additional modules in parallel at any time to increase capacity. The BMS compensates for differences in charge between new and old modules to a certain extent. However, it is recommended to combine modules with a similar state of ageing or to perform a one-off full balancing of the system. Scope of delivery: Deye SE-F5 Pro-C (5.12 kWh)This product is a set and consists of the inverter unit and the separate battery modules.1 x Deye SE-F5 Pro-C battery moduleThe main unit with 5.12 kWh capacity, integrated battery management system (BMS) and LCD display for status indication.1 x wall bracket (Mounting Bracket)A mounting plate that is fixed to the wall in order to securely hang the battery module.1 x set of battery connection cablesUsually includes a negative battery cable as well as the positive connection plug (or a pair of cables) for connection to the inverter.1 x RJ45 communication cableRequired for the data connection between the battery (PCS port) and the hybrid inverter.1 x grounding cable (Grounding Cable)A yellow-green cable for the proper protective earth connection on the housing.1 x set of mounting materialConsisting of expansion plugs (usually M6x100), screws (M4) and hexagon screws for fixing to the bracket.4 x stacking brackets (Stacking Brackets)Special brackets that are required if several modules are not hung on the wall, but are instead to be stacked on top of each other on the floor.1 x positioning template (Positioning Paperboard)A cardboard template for marking the drill holes for the wall bracket exactly.1 x user manual (User Manual)Technical manual with installation instructions and safety information.

By connecting up to six towers in parallel, flexible scaling to significantly higher capacities is possible.How many cycles does the battery last?According to the datasheet, the storage system achieves over 6,000 charge cycles at 90 % depth of discharge (DoD). 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.
