For operation you necessarily need the BMS control unit (head unit) and the base, which are included in the basic package of the FLH96050SG01 system. Additionally, you need at least two of these modules in a tower to reach the minimum voltage for most high-voltage inverters.Can I expand my storage at any time?Basically yes. However, it is recommended to carry out expansions within the first years after initial installation. If new modules are added to very old modules, the difference in capacity (due to the natural ageing of the old modules) can slightly limit the overall performance of the tower, as the system is oriented towards the weakest link.How heavy is a module?A single module weighs approx. 53 kg. For assembly (lifting onto the stack), two people or a suitable lifting aid are therefore recommended.Does the module also fit Felicity low-voltage systems?No. Felicity Solar also offers low-voltage storage (e.g. for 48V systems). Due to its voltage (approx. 100V) and connections, this module is exclusively suitable for the high-voltage (HV) series. Scope of delivery: Felicity Solar FLH96050SMG01 (5.12 kWh HV expansion module) 1 x Felicity FLH48100-S battery module (5.12 kWh)A stackable high-voltage LiFePO4 storage module for capacity expansion of existing Felicity FLH systems.1 x set of internal connection cables (Plug & Play)Short DC power bridges and communication cables for the electrical and data integration of the module into the existing stack.1 x mounting kit (screws and connection brackets)All necessary mechanical small parts for secure fixing of the module onto the underlying housing within the battery tower.1 x user manual / installation leafletShort manual with specific instructions for physical stacking and integration into the existing battery management system.

Most 3-phase hybrid inverters (e.g., Deye 10kW/12kW, Growatt SPH series) are perfectly suited for this battery size. Pay attention to the permissible voltage range (Input Voltage Range) of the inverter.How big is the storage tower?Since four modules plus the BMS unit (base/top) are stacked on top of each other, the tower reaches a considerable height. Make sure there is enough vertical space at the installation location (e.g., basement, garage) and that the floor can bear the weight of over 200 kg (solid ground recommended).Can I connect two of these towers in parallel?Yes, where there is very high energy demand (e.g., multi-generation house or business), several of these towers can be connected in parallel to one or more inverters to achieve capacities of 40 kWh or more. However, this requires careful coordination with the inverter.Why LiFePO4 and not Li-Ion (NMC)?LiFePO4 (lithium iron phosphate) is considered the safest cell chemistry on the market. It is thermally stable (no "thermal runaway" in normal faults), cobalt-free (more environmentally friendly), and has a significantly higher cycle life than traditional Li-Ion batteries, which is crucial for the economics of an investment of this size. Scope of delivery: Felicity Solar FLH96050SG01 (20.48 kWh HV Battery Storage Set) 1 x Felicity FLH96050SCG01 BMS control unitThe central high-voltage management module, which is mounted on top of the stack and controls communication with the inverter.4 x Felicity FLH48100-S battery modules (5.12 kWh each)Four stackable high-voltage LiFePO4 storage units that together provide the total capacity of 20.48 kWh.1 x base plate (Base)A solid base for floor mounting, serving as a stable pedestal for the entire battery tower.1 x set of internal connection cables (Plug & Play)Short DC bridges and communication cables for the electrical coupling of the four modules within the tower.1 x external high voltage cable set (DC)A pair of specialised power cables for the safe connection of the battery tower to the high-voltage hybrid inverter.1 x communication cable (BMS-to-Inverter)A pre-assembled data cable for connecting the control unit to the inverter via CAN or RS485 interface.1 x mounting set (tilt protection & screws)All mounting materials for wall fixing of the tower as well as screws for mechanical module connections.1 x user manual (User Manual)A technical manual with detailed instructions for stacking, BMS configuration, and important safety notes.

The wireless plug connection between the modules eliminates complex cabling, reducing susceptibility to errors. Characteristics ModelFelicity Solar FLH96050SG01  (25.6 kWh) System seriesFLH series (High Voltage Stackable) Configuration5x battery modules (5.12 kWh / 102.4 V each) + 1x control unit Nominal energy25.6 kWh Nominal voltage512 V Capacity50 Ah Voltage range420 V - 570 V Charging current / discharging current25 A (recommended) / 50 A (maximum) SafetyIntegrated aerosol fire extinguishing system Protection classIP65 (protected against dust and water jets) Weight (kg)approx. 300 (total system)  FAQs for the Felicity FLH96050SG01 (25.6 kWh)Which inverter is suitable for this voltage?With a nominal voltage of 512 V and a final charging voltage of up to 576 V, you need an inverter that supports this high range. The Deye SUN-10K/12K-SG01HP3 (battery input up to 700 V) is ideal for this. Some smaller HV inverters stop at 500 V or 600 V – here, you need to check the data sheet carefully to avoid overvoltage errors.How high is the storage tower?The tower, consisting of 5 modules plus BMS head and base, reaches a height of approx. 1.50 m to 1.60 m. Make sure you have a stable, level surface as the weight is distributed over a relatively small footprint (approx. 60x40 cm).Can I expand this configuration further?Technically, with the FLH96050SG01 series you can usually go up to 6 modules (approx. 30 kWh) per tower, as the voltage otherwise becomes too high for most inverters. If you need even more storage, you can alternatively place a complete second tower in parallel next to it (master/slave operation), provided the inverter supports this.Is the system suitable for commercial use?Absolutely. Due to the high capacity, cycle stability and safety features (extinguishing system), this storage unit is often used in commercial projects to increase self-sufficiency or safeguard sensitive loads. Scope of delivery: Felicity Solar FLH96050SG01 (25.6 kWh HV battery storage set) 1 x Felicity FLH96050SCG01 BMS control unitThe central high-voltage management module, which monitors the cells and communicates with the inverter.5 x Felicity FLH48100-S battery modules (each 5.12 kWh)Five stackable high-voltage LiFePO4 storage modules which, when connected in series, result in the total capacity of 25.6 kWh.1 x base plate (Base)A stable foundation for floor mounting, on which the five battery modules and the control unit are safely stacked.1 x set of internal connection cables (Plug & Play)Short plug-in connections for electrical coupling and data transmission between the five battery modules within the tower.1 x external high-voltage cable set (DC)A pair of specialised high-power cables for the safe connection of the battery tower to the high-voltage hybrid inverter.1 x communication cable (BMS-to-Inverter)A pre-configured data cable for connecting the control unit to the inverter (CAN/RS485).1 x mounting kit (tilt protection & screws)All mounting materials for fixing the tower to the wall and screws for the mechanical module connections.1 x User manualA technical manual with instructions for stacking, configuring the BMS and important safety information for high-voltage systems.

The Felicity Solar FLH96050SG01 in the 30.72 kWh version is the absolute flagship model of this high-voltage series and represents the maximum that is possible in a single storage tower. Consisting of six powerful battery modules, this system offers massive energy density with minimal footprint. It is the perfect solution for large multi-generation houses, agricultural enterprises, commercial properties or sophisticated homes with maximum autonomy requirements and high night-time energy demands (e.g. due to electric vehicle fleets or server rooms).Highlights at a glanceMaximum tower capacity: With 30.72 kWh, this system fully exploits the capacity of a single battery stack – more energy on less than 0.3 m² floor space is hardly possible.6-stack design: The system consists of six 5.12 kWh modules and the control unit. Thanks to the wireless plug-in system, installation remains straightforward despite the size.Highest system voltage: With a nominal voltage of over 600 volts, the system operates extremely efficiently, minimises line losses and enables very high charging and discharging performance.Industrial safety: Like all models in the series, this version has LiFePO4 cells and an integrated aerosol fire extinguishing system in every module for maximum protection.Commercial-ready: Ideal for peak shaving (load peak capping) and emergency power supply in small businesses or large residential buildings.Smart management: The BMS actively monitors and balances the six modules and communicates via CAN/RS485 with compatible inverters.The power station for business and large-scale consumersWith over 30 kWh of storage capacity, this system leaves the scope of classic single-family home applications. It is designed to efficiently use large PV systems (> 20 kWp). During the day, the huge storage is charged to supply entire businesses or several households at night. High-voltage technology ensures that even at high discharge currents (e.g. fast charging of electric cars) efficiency remains high and heat generation low.Installation and staticsWith this configuration, the storage tower reaches a height of approx. 1.70 m to 1.80 m and a weight of over 300 kg. The modular construction makes transport to the installation site easier, but the ground must be absolutely level, firm and load-bearing (concrete floor recommended). Wall mounting for anti-tip protection is highly recommended at this height. Characteristics ModelFelicity Solar FLH96050SG01 (30.72 kWh) System seriesFLH series (High Voltage Stackable) Configuration6x battery modules (5.12 kWh / 102.4 V each) + 1x control unit Nominal energy30.72 kWh Nominal voltage614.4 V Capacity50 Ah Voltage range504 V - 684 V Charging / discharging current25 A (recommended) / 50 A (maximum) SafetyIntegrated aerosol fire extinguishing system Protection classIP65 (protected against dust and water jets) Weight (kg)approx. 360 (total system)  FAQs for the Felicity FLH96050SG01 (30.72 kWh)Which inverter do I need for 6 modules?This is the most critical point for this size: the final charging voltage is close to or above 700 V. You absolutely need an inverter that supports this high battery voltage range (e.g. Deye SUN-10K/12K/15K-SG01HP3 or large Solis hybrid devices). Smaller high-voltage inverters, which are only designed for up to 600 V battery voltage, are not compatible!Can I expand the system?A single tower is usually mechanically and electrically stretched to its limits with 6 modules. If you require even more capacity (e.g. 60 kWh), you must build a complete second tower in parallel and connect these via a combiner box or directly to the inverter (depending on the inverter model).Is installation difficult?The principle ("stacking") is simple. However, due to the tower's height (6 modules + head), you may need a small ladder or step for the upper modules. In addition, installation should be carried out by two people to safely lift the 50 kg modules to head height.What happens if a module is defective?Thanks to the modular construction, it's not necessary to replace the entire system. A single defective module can be removed from or replaced within the tower. The BMS may then need to be recalibrated to balance the new voltage levels. Scope of delivery: Felicity Solar FLH96050SG01 (30.72 kWh HV battery storage set) 1 x Felicity FLH96050SCG01 BMS control unitThe central high-voltage management module that handles all monitoring and communication with the inverter.6 x Felicity FLH48100-S battery modules (each 5.12 kWh)Six stackable high-voltage LiFePO4 storage units, connected in series to provide the maximum overall capacity of 30.72 kWh for one tower.1 x base plate (Base)A solid foundation for floor mounting, which serves as a stable base for the high battery tower.1 x set of internal connection cables (Plug & Play)All the required DC bridges and internal data cables for coupling the six modules within the stack.1 x External high-voltage cable set (DC)A pair of specialised power cables for the safe electrical connection of the storage system to the high-voltage hybrid inverter.1 x communication cable (BMS-to-Inverter)A pre-assembled data cable for connecting the control unit to the inverter via CAN or RS485 interface.1 x mounting kit (tilt protection & screws)Special fastening material for wall mounting the tower and all necessary screws for the mechanical connection of the modules.1 x User ManualA technical manual with detailed instructions for stacking, configuring the BMS and important safety notes.
