Felicity Solar FLH96050SG01 high-voltage storage system 30.72 kWh

The Felicity Solar FLH96050SG01 in the 30.72 kWh This model is the absolute top-of-the-range model in this high-voltage series and represents the maximum that is possible in a single storage tower. Consisting of six high-performance battery modules, this system offers a massive energy density within a minimal footprint. It is the perfect solution for large multi-generational homes, farms, commercial premises or high-end private residences with a strong emphasis on self-sufficiency and high night-time energy requirements (e.g. due to electric vehicle fleets or server rooms).

Highlights at a glance

• Maximum tower capacity: At 30.72 kWh, this system makes full use of the capacity of a single battery stack – it is almost impossible to achieve more energy in a footprint of less than 0.3 m².
• 6-stack configuration: The system consists of six 5.12 kWh modules and the control unit. Thanks to the wireless plug-in system, the installation remains neat and tidy despite its size.
• Maximum system voltage: With a rated voltage of over 600 volts, the system operates extremely efficiently, minimises line losses and enables very high charging and discharging rates.
• Industrial safety: Like all models in the series, this one also features LiFePO4 cells and an integrated aerosol fire-suppression system in each module for maximum protection.
• Commercial-ready: Ideal for peak shaving and emergency power supply in small businesses or large residential buildings.
• Smart management: The BMS actively monitors and balances the six modules and communicates with compatible inverters via CAN/RS485.

The power station for commercial and large-scale consumers

With a storage capacity of over 30 kWh, this system goes beyond the scope of traditional single-family home applications. It is designed to make efficient use of large PV systems (> 20 kWp). During the day, the massive storage unit is charged to supply entire businesses or multiple households at night. The high-voltage technology ensures that, even with high discharge currents (e.g. fast charging of electric cars), efficiency remains high and heat generation low.

Installation and structural analysis

With this configuration, the storage tower reaches a height of approx. 1.70 m to 1.80 m and weighs over 300 kg. Whilst the modular design facilitates transport to the installation site, the ground must be level, firm and load-bearing (concrete floor recommended). Wall mounting to prevent tipping is strongly recommended at this height.
 

FAQs on the Felicity FLH96050SG01 (30.72 kWh)

Which inverter do I need for 6 modules?

This is the most critical aspect at this scale: the final charging voltage is close to or above 700 V. You must use an inverter that supports this high battery voltage range (e.g. Deye SUN-10K/12K/15K-SG01HP3 or large Solis hybrid units). Smaller high-voltage inverters, which are only rated for a battery voltage of up to 600 V, are not Compatible!

Can I expand the system further?

A single tower with 6 modules is generally at its full mechanical and electrical capacity. If you require even more capacity (e.g. 60 kWh), you must set up a second complete tower in parallel and connect it via a combiner box or directly to the inverter (depending on the inverter model).

Is installation difficult?

The principle (“stacking”) is simple. However, due to the height of the tower (6 modules + top section), you may need a small ladder or a step stool for the upper modules. Furthermore, two people should carry out the assembly to safely lift the 50 kg modules to head height.

What happens if a module fails?

Thanks to the modular design, there is no need to replace the entire system. A single faulty module can be removed from the tower or replaced. The BMS may then need to be recalibrated to adjust to the new voltage levels.
