Felicity Solar FLH96050SG01 high-voltage storage unit 15.36 kWh

The Felicity Solar FLH96050SG01 in the version with 15.36 kWh is a performance-optimised high-voltage battery storage system for homes and commercial premises with high energy requirements. By combining three stacked 5.12 kWh modules, this system offers an enormous storage capacity, ideally suited to powering heat pumps, charging electric cars overnight or bridging longer periods of bad weather. Thanks to state-of-the-art LiFePO4 technology and its modular tower design, it combines safety, efficiency and space-saving features.

Highlights at a glance

• Massive capacity: With a usable capacity of 15.36 kWh, this storage system offers sufficient reserves for large households and maximises the self-sufficiency of your PV system.
• Modular stack system: Consists of three battery modules and a control unit, which are connected wirelessly to one another (“Plug & Play”), simplifying installation.
• Maximum safety: Each module features an integrated aerosol fire suppression system and a multi-stage battery management system (BMS) for continuous monitoring of the cells.
• High-voltage efficiency: Compared with low-voltage systems, the higher system voltage results in lower conversion losses and a more efficient supply to high-power loads.
• Long service life: Utilises high-quality lithium iron phosphate (LiFePO4) cells with over 6,000 cycles at a high depth of discharge (DOD).
• Wide compatibility: Communicates seamlessly with common hybrid inverters (e.g. Deye, Growatt, Solis, GoodWe) via CAN/RS485 interfaces.

Maximum independence for your home

With a capacity of 15.36 kWh, this storage system falls into a performance class that far exceeds the standard. It is the perfect solution for the energy transition in the home (“sector coupling”). During the day, it stores surplus solar power, which is then used in the evening and at night for energy-intensive applications such as cooking, the heat pump or the wallbox. This reduces expensive grid consumption to a minimum.

Flexibility and expandability

The system grows with your needs. Should your electricity requirements increase further in the future (e.g. due to a second electric car), the storage tower can be expanded by simply plugging in additional modules (subject to the maximum input voltage of the inverter). The intelligent BMS recognises the new capacities and automatically integrates them into the system.
 

FAQs on the Felicity FLH96050SG01 (15.36 kWh)

Who would benefit from the 15.36 kWh version?

This size is ideal for detached houses with an annual electricity consumption of over 5,000 kWh or households that actively practise sector coupling (heat pump + electric car). It enables a significant proportion of the energy requirement to be met from the storage system, even on cloudy days or in winter.

How heavy is the system during installation?

The entire system weighs over 160 kg. However, as it has a modular design, you do not need to move this weight in one go. The individual battery modules (approx. 50 kg each) and the control unit are stacked on top of one another one by one at the installation site.

Is the storage unit suitable for outdoor use?

The housing has an IP65 protection rating, meaning it is dust-tight and protected against water jets. It can therefore be installed in a garage, a carport or under a canopy. However, to maximise the service life of the cells, we recommend a location protected from direct sunlight and extreme frost (e.g. a cellar or utility room).

Can the system supply emergency power?

Yes, the Felicity high-voltage storage system can deliver high discharge power. When combined with a hybrid inverter capable of providing emergency power (which features a grid switch), the system can continue to supply the domestic grid in the event of a power cut.
