Felicity Solar FLA48314-EU low-voltage battery storage system – 51.2V / 16 kWh

The Felicity Solar FLA48314-EU is a high-performance 48V lithium iron phosphate (LiFePO4) battery, specially developed for efficient energy management in residential buildings and small businesses. With a gross capacity of 16.07 kWh This compact system offers impressive energy density and is the ideal choice for users who prioritise safety, durability and ease of installation.

Thanks to low-voltage technology (48V/51.2V), the storage system is compatible with a wide range of standard hybrid inverters available on the market. Its robust construction and 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 a capacity of over 16 kWh per unit, even larger households and heat pump systems can be reliably supplied with power overnight.
• Safe LiFePO4 chemistry: Lithium iron phosphate technology is extremely thermally stable and offers a service life of over 6,000 cycles at a high depth of discharge.
• Integrated Smart BMS: Continuously monitors cell voltages, currents and temperatures to ensure safe operation and uniform cell ageing.
• Wide compatibility: Works seamlessly with leading 48V inverters (e.g. Victron, Deye, Growatt, GoodWe), offering maximum flexibility when selecting a system.
• 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 for space-saving installation and neat cabling in the plant room or basement.

Areas of application

The FLA48314-EU is highly versatile for use in modern energy concepts:

• Maximising self-consumption
  • Store your solar power during the day to avoid having to draw on the grid at evening times and when it’s cloudy.
• Emergency power & off-grid solutions
  • When used in conjunction with a suitable inverter, the storage system ensures a continuous power supply during power cuts or in remote areas.
• Retrofitting existing systems
  • Ideal for upgrading older PV systems with a modern, durable 48V-based battery storage system.

Installation & Safety Instructions

• Professional installation
  • Due to the high capacities and currents involved, the connection must be carried out by a qualified electrician. Ensure that the battery cables are of sufficient cross-section.
• Site conditions
  • Install the storage unit in a dry, well-ventilated location. The optimum operating temperature is between +15°C and +30°C to ensure the longest possible 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 connecting them.

FAQs on the Felicity Solar FLA48314-EU

Is this storage system compatible with my inverter?

Generally speaking, yes.

• The FLA48314-EU supports the most common protocols for 48V systems. It is compatible with, amongst others, Victron Energy, Deye, Growatt, Voltronic and many other manufacturers. Please check Felicity Solar’s current compatibility list in advance.

How many cycles will the battery last?

Over 6,000 cycles.

• With a depth of discharge (DoD) of 80% and when handled correctly, LiFePO4 chemistry guarantees a service life of over 10 years, making it one of the longest-lasting storage solutions on the market.

Can I increase the capacity at a later date?

Yes.

• You can connect up to 12 FLA48314-EU units in parallel. The system therefore scales flexibly with your energy requirements, whether due to a new electric car or an air-conditioning system.

Does the storage system require active cooling?

No.

• The housing is designed for efficient passive heat dissipation. This means the storage unit operates completely silently, which is particularly advantageous when installed in residential buildings.

How safe is LiFePO4 technology in the home?

Very safe.

• Unlike conventional lithium-ion batteries (NMC), LiFePO4 cells are non-flammable and do not tend to undergo thermal runaway, even if damaged or short-circuited. They are considered the safest choice for home energy storage.
