Felicity Solar FLA48314-EU - 51.2V / 16.1 kWh low-voltage battery storage system
Description
Product information
The Felicity Solar FLA48314-EU is a powerful 48V lithium iron phosphate storage (LiFePO4) system specially developed for efficient energy management in residential buildings and small commercial operations. With a gross capacity of 16.07 kWh this compact system offers impressive energy density and is the ideal choice for users who value safety, durability, and easy installation.
Thanks to the low-voltage technology (48V/51.2V), the storage is compatible with a wide range of commonly available hybrid inverters. The robust construction and the intelligent battery management system (BMS) ensure that your photovoltaic system achieves maximum self-consumption and sustainably reduces your energy costs.
Highlights at a glance
- High storage capacity: With over 16 kWh capacity per unit, even larger households and heat pump systems can be reliably supplied overnight.
- Safe LiFePO4 chemistry: The lithium iron phosphate technology is extremely thermally stable and offers a lifespan of over 6000 cycles with high depth of discharge.
- Integrated smart BMS: Continuously monitors cell voltages, currents and temperatures to guarantee safe operation and uniform cell ageing.
- Broad compatibility: Works seamlessly with leading 48V inverters (e. g. Victron, Deye, Growatt, GoodWe), offering maximum flexibility in system selection.
- Scalable system: Up to 12 units can be connected in parallel to achieve total capacities of up to 192 kWh for commercial applications.
- Simple wall mounting: The compact design allows space-saving installation and neat wiring in the technical room or basement.
Areas of application
The FLA48314-EU is versatile for modern energy concepts:
- Maximising self-consumption
- Store your solar energy during the day to avoid expensive grid supply in the evenings and when it is cloudy.
- Emergency power & island solutions (off-grid)
- In combination with a suitable inverter, the storage ensures the power supply during grid failures or in remote areas.
- Retrofitting existing systems
- Ideal for upgrading older PV systems with a modern, long-lasting 48V battery storage.
Assembly & Safety Instructions
- Professional installation
- Due to the high capacities and currents, the connection must be carried out by a qualified electrician. Ensure sufficiently sized battery cables (cross-section).
- Site conditions
- Install the storage in a dry, well-ventilated place. The optimum operating temperature is between +15°C and +30°C to achieve maximum service life.
- Parallel connection
- When expanding the system, ensure that all battery modules have the same software version and a similar state of charge (SOC) before connection.

FAQs about the Felicity Solar FLA48314-EU
Is this storage compatible with my inverter?
Usually yes.
- The FLA48314-EU supports the most common protocols for 48V systems. It is compatible with Victron Energy, Deye, Growatt, Voltronic and many other manufacturers. Please check Felicity Solar’s current compatibility list in advance.
How many cycles does the battery last?
Over 6000 cycles.
- At a depth of discharge of 80% (DoD) and proper handling, the LiFePO4 chemistry guarantees a service life of over 10 years, making it one of the most durable storage solutions on the market.
Can I expand the capacity later?
Yes.
- You can connect up to 12 units of the FLA48314-EU model in parallel. In this way, the system grows flexibly with your energy requirements, whether due to a new EV or an air conditioner.
Does the storage require active cooling?
No.
- The housing is designed for efficient passive heat dissipation. As a result, the storage operates completely silently, which is especially beneficial for installation in residential buildings.
How safe is the LiFePO4 technology in the home?
Very safe.
- Unlike conventional lithium-ion batteries (NMC), LiFePO4 cells are not flammable and are not prone to thermal runaway even in the event of damage or short circuit. They are considered the safest choice for home storage.
