Product information
The Felicity Solar FLH96050SG01 with 25.6 kWh storage capacity is the most powerful single configuration of this high-voltage series and marks the top of home storage solutions. This system, consisting of a tower with five battery modules, offers massive energy reserves for large detached houses, multi-family houses or commercial applications. With a nominal voltage of 512 volts, it operates highly efficiently and is perfectly suited to supply energy-intensive consumers such as heat pumps or several electric vehicles simultaneously, even at night.
Highlights at a glance

- 5-stack design: The storage unit consists of five stacked 5.12 kWh modules plus control unit – compact in footprint, large in output.
- Maximum high-voltage efficiency: The system voltage of 512 V ensures minimal conversion losses and high discharge power with low heat generation.
- Industrial safety standard: Equipped with LiFePO4 cells and an integrated aerosol fire extinguishing system in each module for maximum fire protection.
- Sector coupling pure: Ideally dimensioned for the combination of photovoltaics, heat pump and e-mobility (wallbox).
- Proven communication: Compatible with powerful high-voltage hybrid inverters (e.g. Deye, Solis, GoodWe, Megarevo).
Powerhouse for high demands
This expansion level is intended for users who do not want to compromise. 25.6 kWh means that you can use the solar power produced during the day almost completely yourself, even if your night-time consumption is very high. For small businesses (bakeries, offices with server rooms), this storage unit also offers an effective option for peak shaving and serves as a powerful emergency power source in the event of a grid failure.
Installation and handling
Despite an overall weight of over 260 kg, installation remains feasible thanks to the modular concept. The individual modules (each approx. 50 kg) are stacked one after the other at the installation site to form a tower. The wireless plug connection between the modules eliminates complex cabling, reducing susceptibility to errors.

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.

The Felicity Solar FLH96050SMG01 is the central battery expansion module for the high-voltage storage series FLH96050SG01. With a capacity of 5.12 kWh per unit, this module is used to enlarge existing storage systems or to individually configure a new storage tower. Equipped with durable LiFePO4 cells and an innovative plug-in system, it enables a flexible adjustment of storage capacity to your growing energy demand – without elaborate rewiring.Highlights at a glanceHigh energy density: Each module offers a storage capacity of 5.12 kWh, ideally portioned for gradual expansion.Wireless stacking: The integrated plug-in system on the top and bottom enables a "Plug & Play" installation by simply stacking the modules.Integrated fire protection: An advanced aerosol fire extinguishing system inside the module ensures maximum safety in your home.Long-lasting technology: Uses high-quality lithium iron phosphate cells (LiFePO4) for over 6000 charge cycles and high operational reliability.Robust housing: The IP65 protection class reliably protects the cell electronics from dust and moisture.High-voltage architecture: The module is designed for series connection in high-voltage towers, increasing system efficiency.Flexibility for your energy systemThe FLH96050SMG01 module is the building block of your independence. Whether you start with a small storage (e.g. 2 modules = 10.24 kWh) and expand later, or your consumption has increased due to purchasing an electric car: This module grows with you. You can combine between 2 and 6 of these modules in a tower (depending on BMS and inverter).Safety and installationFelicity Solar sets new standards in safety. Each individual module has sensors and an extinguishing unit that reacts instantly in the event of critical faults. Installation is extremely simple: the module is placed on the existing tower (or base). Guide pins ensure the correct fit, and the electrical connection is established automatically. No cables have to be screwed between the battery modules.

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.
