Felicity Solar high-voltage storage system FLH96050SG01 25.6 kWh

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

• Enormous capacity: With 25.6 kWh usable capacity you achieve maximum independence from the grid and can also bridge periods of bad weather.
• 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.
 

Characteristics

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.
