Felicity Solar high-voltage storage tank FLH96050SG01 30.72 kWh
Description
Product information
The Felicity Solar FLH96050SG01 in the 30.72 kWh version is the absolute flagship model of this high-voltage series and represents the maximum that is possible in a single storage tower. Consisting of six powerful battery modules, this system offers massive energy density with minimal footprint. It is the perfect solution for large multi-generation houses, agricultural enterprises, commercial properties or sophisticated homes with maximum autonomy requirements and high night-time energy demands (e.g. due to electric vehicle fleets or server rooms).
Highlights at a glance
- Maximum tower capacity: With 30.72 kWh, this system fully exploits the capacity of a single battery stack – more energy on less than 0.3 m² floor space is hardly possible.
- 6-stack design: The system consists of six 5.12 kWh modules and the control unit. Thanks to the wireless plug-in system, installation remains straightforward despite the size.
- Highest system voltage: With a nominal voltage of over 600 volts, the system operates extremely efficiently, minimises line losses and enables very high charging and discharging performance.
- Industrial safety: Like all models in the series, this version has LiFePO4 cells and an integrated aerosol fire extinguishing system in every module for maximum protection.
- Commercial-ready: Ideal for peak shaving (load peak capping) and emergency power supply in small businesses or large residential buildings.
- Smart management: The BMS actively monitors and balances the six modules and communicates via CAN/RS485 with compatible inverters.
The power station for business and large-scale consumers
With over 30 kWh of storage capacity, this system leaves the scope of classic single-family home applications. It is designed to efficiently use large PV systems (> 20 kWp). During the day, the huge storage is charged to supply entire businesses or several households at night. High-voltage technology ensures that even at high discharge currents (e.g. fast charging of electric cars) efficiency remains high and heat generation low.
Installation and statics
With this configuration, the storage tower reaches a height of approx. 1.70 m to 1.80 m and a weight of over 300 kg. The modular construction makes transport to the installation site easier, but the ground must be absolutely level, firm and load-bearing (concrete floor recommended). Wall mounting for anti-tip protection is highly recommended at this height.

FAQs for the Felicity FLH96050SG01 (30.72 kWh)
Which inverter do I need for 6 modules?
This is the most critical point for this size: the final charging voltage is close to or above 700 V. You absolutely need an inverter that supports this high battery voltage range (e.g. Deye SUN-10K/12K/15K-SG01HP3 or large Solis hybrid devices). Smaller high-voltage inverters, which are only designed for up to 600 V battery voltage, are not compatible!
Can I expand the system?
A single tower is usually mechanically and electrically stretched to its limits with 6 modules. If you require even more capacity (e.g. 60 kWh), you must build a complete second tower in parallel and connect these 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 tower's height (6 modules + head), you may need a small ladder or step for the upper modules. In addition, installation should be carried out by two people to safely lift the 50 kg modules to head height.
What happens if a module is defective?
Thanks to the modular construction, it's not necessary to replace the entire system. A single defective module can be removed from or replaced within the tower. The BMS may then need to be recalibrated to balance the new voltage levels.

However, the current firmware allows a technical residual consumption of approx. 20 W. Users report that adjustments to Modbus registers or external energy management systems such as ioBroker can indeed achieve 0 W grid consumption. For standard applications such as full feed-in or net metering, the factory setting is usually entirely sufficient.Are the charge/discharge currents sufficient for large high-voltage batteries?Yes. According to the data sheet, the inverter allows 50 A charging or discharging current in each direction, which enables up to 20 kW output at a battery voltage of 400 V. Systems such as BYD HVS/HVM, Pylontech Force H and Dyness Tower are listed as fully compatible in the official Approved Battery List. This allows even large storage blocks to be operated quickly and in sync with the BMS.How much kWp can I connect, without the inverter clipping?On the 15 kW model, up to 30 kW PV access power and 24 kW PV input power are permitted. A typical 18 kWp PV installation results in a DC/AC ratio of 1.2, which is within the recommended oversizing range of 0.8 to 1.3. Slight clipping may occur on a few summer days but has little effect on total yield and offers valuable expansion reserves.Can I install the inverter outdoors?Yes. The device is protected against dust and water jets according to IP65, operates reliably at temperatures from –40 °C to +60 °C and tolerates 100 % humidity. For outdoor installation, the manufacturer recommends a protected, well-ventilated location to ensure unrestricted air cooling (≤ 55 dB(A)) and prevent fan blockage.Can the inverter be fully controlled via app or remote access?Yes. All relevant functions can be remotely controlled via Deye Cloud or the local SUN APP: parameter changes, firmware updates and emergency shutdowns are no problem. The app manual guides you step by step through the Wi-Fi setup including connection using the internal hotspot network. RS485, CAN, LAN and 4G sticks are also available for connecting external EMS solutions.
