Felicity Solar high-voltage storage tank FLH96050SG01 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 businesses with high energy requirements. By combining three stacked 5.12 kWh modules, this system offers an enormous storage capacity, ideally suited to running heat pumps, overnight charging of electric vehicles, or bridging long periods of poor weather. Thanks to modern LiFePO4 technology and modular tower design, it combines safety, efficiency, and space savings.

Highlights at a glance

• Massive capacity: With 15.36 kWh usable capacity, this storage offers enough reserves for large households and maximises the degree of self-sufficiency of your PV system.
• Modular stack system: Consists of three battery modules and one control unit that wirelessly plug together (“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: The higher system voltage ensures lower conversion losses and more efficient supply for high-power loads compared to low-voltage systems.
• Long service life: Uses high-quality lithium iron phosphate cells (LiFePO4) with over 6000 cycles at high depth of discharge (DOD).
• Wide compatibility: Seamless communication with common hybrid inverters (e.g. Deye, Growatt, Solis, GoodWe) via CAN/RS485 interfaces.

Maximum independence for your home

With 15.36 kWh, this storage system is in a performance class that far exceeds standard. It is the perfect solution for the energy transition at home (“sector coupling”). During the day it stores surplus solar power, which in the evening and at night is available for energy-intensive uses like cooking, the heat pump, or the EV charger. This minimises costly grid import to a minimum.

Flexibility and expandability

The system grows with your needs. If your electricity demand increases in the future (e.g. due to a second EV), the storage tower can be expanded simply by adding more modules (depending on the maximum input voltage of the inverter). The smart BMS recognises new capacities and automatically integrates them into the system.
 

Characteristics

FAQs for the Felicity FLH96050SG01 (15.36 kWh)

Who is the 15.36 kWh version suitable for?

This size is ideal for detached houses with an annual electricity consumption of over 5,000 kWh or households actively using sector coupling (heat pump + EV). It allows a significant share of demand to be covered from the storage system even on cloudy days or in winter.

How heavy is the system during installation?

The total system weighs over 160 kg. However, thanks to the modular design, you do not need to move the full weight at once. Each individual battery module (about 50 kg each) and the control unit are stacked one after the other at the installation site.

Is the storage suitable for outdoor use?

The housing has protection rating IP65, i.e. it is dust-tight and protected against water jets. Installation in a garage, carport or beneath a canopy is therefore possible. However, to maximise the life of the cells, we recommend a location protected from direct sunlight and extreme frost (e.g. cellar or utility room).

Can the system supply emergency power?

Yes, the Felicity high-voltage storage can provide high discharge power. In combination with an emergency power capable hybrid inverter (with grid switching), the system can continue to supply the home grid in the event of a power failure.
