Felicity Solar high-voltage storage tank FLH96050SG01 10.24 kWh

The Felicity Solar FLH96050SG01 (10.24 kWh) is a powerful and modular high-voltage battery storage system, specially developed for modern photovoltaic systems in single and multi-family houses. Based on safe lithium iron phosphate technology (LiFePO4), this system with a usable capacity of 10.24 kWh offers the ideal energy reserve for households with high demand, heat pumps or electric vehicles. Thanks to its stackable design, the storage unit can be installed to save space and flexibly expanded as energy demand increases.

Highlights at a glance

• High storage capacity: With 10.24 kWh (consisting of two 5.12 kWh modules), the system provides enough buffer to significantly increase self-consumption and minimise grid usage.
• Modular stack design: The wireless plug-in system enables fast "Plug & Play" installation without complex cabling between the modules.
• Maximum safety: Equipped with an integrated aerosol fire extinguishing system and advanced battery management system (BMS) for maximum protection against overheating and malfunctions.
• Long-lasting technology: The LiFePO4 cells guarantee over 6000 charging cycles at high depth of discharge (DOD), providing investment security for many years.
• 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 IP65 protection rating, the storage is protected against dust and water jets and is suitable for flexible installation locations (indoors and protected outdoors).

Efficiency through high-voltage technology

Unlike low-voltage systems, the Felicity FLH96050SG01 operates in this configuration at a nominal voltage of approximately 204.8 V. This significantly reduces conversion losses and enables the use of thinner cable cross-sections while increasing the overall efficiency of the PV system. The system is therefore perfect for operating high-power consumers, as high discharge currents can be provided without significant heat generation.

Scalability for the future

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

Characteristics

FAQs about the Felicity FLH96050SG01

Which inverters are compatible?

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

Can I expand the storage later?

Yes, the system is modular. You can subsequently add further 5.12 kWh modules of the same type (up to a certain maximum voltage of the inverter, usually up to 6 modules per tower). However, it is recommended to carry out expansions in a timely manner to minimise capacity differences due to aging.

What does the integrated aerosol extinguishing system mean?

This is an advanced safety feature. Each module is equipped with sensors that, in the extremely unlikely event of thermal runaway (fire inside), automatically release an extinguishing aerosol to immediately stifle the source of the fire and prevent it spreading.

Is the storage emergency power capable?

Yes, the battery is powerful enough to supply the home grid during a power failure in combination with a backup-capable hybrid inverter. The high-voltage technology ensures stable discharge performance, even for larger consumers.
