Felicity Solar FLH96050SG01 high-voltage storage system 10.24 kWh

The Felicity Solar FLH96050SG01 (10.24 kWh) is a high-performance, modular high-voltage battery storage system, specifically developed for modern photovoltaic systems in detached and multi-occupancy dwellings. Based on safe lithium iron phosphate (LiFePO4) technology, this system, with a usable capacity of 10.24 kWh, offers the ideal energy reserve for households with high energy requirements, heat pumps or electric vehicles. Thanks to its stackable design, the storage system can be installed in a space-saving manner and flexibly expanded as energy requirements increase.

Highlights at a glance

• High storage capacity: With a capacity of 10.24 kWh (consisting of two 5.12 kWh modules), the system provides sufficient buffer capacity to significantly increase self-consumption and minimise grid draw.
• Modular stack design: The wireless plug-in system enables quick ‘plug-and-play’ installation without the need for complex cabling between the modules.
• Maximum safety: Equipped with an integrated aerosol fire suppression system and advanced battery management (BMS) for maximum protection against overheating and malfunctions.
• Long-lasting technology: The LiFePO4 cells guarantee over 6,000 charge cycles at a high depth of discharge (DOD), ensuring a secure investment for many years to come.
• Wide compatibility: The high-voltage system works efficiently with leading hybrid inverters (e.g. Deye, Solis, GoodWe, Growatt) and communicates via CAN/RS485.
• Robust housing: With an IP65 protection rating, the battery is protected against dust and water jets and is suitable for flexible installation locations (indoors and in sheltered outdoor areas).

Efficiency through high-voltage technology

Unlike low-voltage systems, the Felicity FLH96050SG01 operates in this configuration at a nominal voltage of approx. 204.8 V. This significantly reduces conversion losses and allows the use of thinner cable cross-sections whilst increasing the overall efficiency of the PV system. The system is therefore perfectly suited to powering high-power loads, as high discharge currents can be supplied without significant heat build-up.

Scalability for the future

A key advantage of this system is its flexibility. Start with 10.24 kWh and simply expand as required by adding further modules (up to 6 modules per tower possible, approx. 30 kWh). The intelligent BMS automatically recognises the new modules and integrates them into the system management.
 

FAQs on the Felicity FLH96050SG01

Which inverters are compatible?

The Felicity high-voltage storage system is compatible with a wide range of high-voltage hybrid inverters. Officially supported brands include Deye, Solis, GoodWe, Growatt, Megarevo and SofarSolar. Always check the inverter manufacturer’s current compatibility list before purchasing.

Can I upgrade the storage capacity at a later date?

Yes, the system has a modular design. You can add further 5.12 kWh modules of the same type at a later date (up to a certain maximum voltage of the inverter, usually up to 6 modules per tower). However, it is recommended that you carry out any expansions as soon as possible to minimise capacity differences caused by ageing.

What does the integrated aerosol extinguishing system mean?

This is an advanced safety feature. Each module is fitted with sensors which, in the extremely unlikely event of a thermal runaway (internal fire), automatically release a fire-suppressant aerosol to immediately smother the source of the fire and prevent it from spreading.

Is the storage unit capable of providing emergency power?

Yes, the battery is powerful enough to supply the domestic mains supply in the event of a power cut when used in conjunction with a hybrid inverter capable of emergency power supply. The high-voltage technology ensures stable discharge performance, even for larger loads.
