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.

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.

With an impressive capacity of 11.8 kWh in a single housing, this model is aimed at homeowners who want to realise a large storage capacity in a small space and with minimal cabling.In contrast to modular systems, where you often have to stack two to three modules for 10-12 kWh, the FLA48230-EU offers this energy in a single, wall-mountable block. It is particularly popular in combination with Deye, Growatt or Victron inverters and is characterised by an excellent price-performance ratio.Highlights at a glanceMassive capacity (11.8 kWh): Offers 230 Ah at 51.2 V in a single device. This drastically reduces the installation effort, as fewer cable bridges and connections are required than with small storage systems.Safe LiFePO4 technology: Utilises lithium iron phosphate cells which are considered thermally stable, intrinsically safe (no thermal runaway) and extremely durable.Integrated display & BMS: A front-mounted LCD display shows SOC (state of charge), voltage and cell status. The BMS protects against overcharging, deep discharge and overheating.Space-saving wall mounting: The slimline design enables flat wall mounting (similar to a radiator), saving valuable floor space in the plant room.High cycle stability: Designed for >6000 cycles (at 80% DOD / 25°C). This corresponds to a service life of over 15 years with daily use.Wide compatibility: Has CAN and RS485 interfaces and is compatible with the market leaders in the 48V segment (Deye, Victron, GoodWe, Growatt, SMA via CAN box).Built-in DC isolator switch: Often has an integrated circuit breaker on the side to safely and quickly disconnect the battery from the system.Areas of applicationThe FLA48230-EU is ideal for medium to large households:Self-consumption optimisation: Stores enough energy to power households with heat pumps or electric cars through the night.Emergency power supply (backup): In combination with hybrid inverters (e.g. Deye 12K), the storage system can supply the entire house in the event of a grid failure.Off-grid systems: Popular for self-sufficient holiday homes due to its robust design and high capacity.Technology & Advantages"All-in-one" advantage: Instead of wiring three 4kWh blocks (sources of error, contact resistances, space requirements), you only install one unit here. The BMS only has to balance one large cell block, which is often more efficient.Scalability: Despite its size, the system is expandable. Up to 12 or 15 units (depending on the firmware) can be connected in parallel to build storage systems in the three-digit kWh range.Ease of maintenance: The connections are easily accessible and the display allows diagnostics without a laptop/PC.Installation & safety instructionsWeight warning: With over 100 kg this storage system is extremely heavy. The wall bracket must be anchored in load-bearing masonry (concrete/brick). Installation on plasterboard walls is not possible without solid reinforcement. Use a pallet truck or lift for installation.Cable cross-section: Due to the high currents (up to 120A), battery cables with at least 35mm², better 50mm² can be used to minimise voltage drops.DIP switch: When communicating with the inverter (esp. Deye/Victron), the DIP switches on the communication port must be set correctly to define the BMS protocol. Characteristics ModelFelicity Solar FLA48230-EU Technology**LiFePO4** (Lithium Iron Phosphate) - Safe & Durable Nominal voltage**51.2 V** (standard low voltage system) Capacity**230 Ah** Energy content**11.77 kWh** (Marketed as ~11.8 kWh) Usable energy (DOD)approx. 90% - 95% (depending on inverter setting) Lifespan**≥ 6000 cycles** (at 25°C, 80% DOD) Communication**CAN / RS485** (Compatible with Deye, Growatt, etc.) Mounting**Wall mounting** (bracket included) or stand Weightapprox. **100 - 105 kg** (Attention: Very heavy!)
