Felicity Solar FLA48230-EU low-voltage battery storage - 51.2V / 11.8 kWh
Description
Product information
The Felicity Solar FLA48230-EU is a powerful lithium iron phosphate (LiFePO4) home storage system in the low-voltage range (48V). With an impressive capacity of 11.8 kWh in a single housing, this model is aimed at homeowners who want to realise a large storage capacity in a small space and with minimal cabling.
In contrast to modular systems, where you often have to stack two to three modules for 10-12 kWh, the FLA48230-EU offers this energy in a single, wall-mountable block. It is particularly popular in combination with Deye, Growatt or Victron inverters and is characterised by an excellent price-performance ratio.
Highlights at a glance
- Massive capacity (11.8 kWh): Offers 230 Ah at 51.2 V in a single device. This drastically reduces the installation effort, as fewer cable bridges and connections are required than with small storage systems.
- Safe LiFePO4 technology: Utilises lithium iron phosphate cells which are considered thermally stable, intrinsically safe (no thermal runaway) and extremely durable.
- Integrated display & BMS: A front-mounted LCD display shows SOC (state of charge), voltage and cell status. The BMS protects against overcharging, deep discharge and overheating.
- Space-saving wall mounting: The slimline design enables flat wall mounting (similar to a radiator), saving valuable floor space in the plant room.
- High cycle stability: Designed for >6000 cycles (at 80% DOD / 25°C). This corresponds to a service life of over 15 years with daily use.
- Wide compatibility: Has CAN and RS485 interfaces and is compatible with the market leaders in the 48V segment (Deye, Victron, GoodWe, Growatt, SMA via CAN box).
- Built-in DC isolator switch: Often has an integrated circuit breaker on the side to safely and quickly disconnect the battery from the system.
Areas of application
The FLA48230-EU is ideal for medium to large households:
- Self-consumption optimisation: Stores enough energy to power households with heat pumps or electric cars through the night.
- Emergency power supply (backup): In combination with hybrid inverters (e.g. Deye 12K), the storage system can supply the entire house in the event of a grid failure.
- Off-grid systems: Popular for self-sufficient holiday homes due to its robust design and high capacity.
Technology & Advantages
- "All-in-one" advantage: Instead of wiring three 4kWh blocks (sources of error, contact resistances, space requirements), you only install one unit here. The BMS only has to balance one large cell block, which is often more efficient.
- Scalability: Despite its size, the system is expandable. Up to 12 or 15 units (depending on the firmware) can be connected in parallel to build storage systems in the three-digit kWh range.
- Ease of maintenance: The connections are easily accessible and the display allows diagnostics without a laptop/PC.
Installation & safety instructions
- Weight warning: With over 100 kg this storage system is extremely heavy. The wall bracket must be anchored in load-bearing masonry (concrete/brick). Installation on plasterboard walls is not possible without solid reinforcement. Use a pallet truck or lift for installation.
- Cable cross-section: Due to the high currents (up to 120A), battery cables with at least 35mm², better 50mm² can be used to minimise voltage drops.
- DIP switch: When communicating with the inverter (esp. Deye/Victron), the DIP switches on the communication port must be set correctly to define the BMS protocol.

FAQs for the Felicity FLA48230-EU
Does this battery work with the Deye SUN-12K-SG04LP3?
Yes, excellent. This is one of the most common combinations. The battery is connected via CAN bus. In the Deye inverter, you usually select "Lithium Mode" and the protocol "00" (or "12" for Felicity, depending on the firmware), and the system automatically recognises the 230Ah.
Can I retrofit two of these batteries later?
Yes. You can connect several FLA48230s in parallel. One battery is configured as the "master" (DIP switch 1 ON) and the others as "slaves". Important: The batteries should have the same voltage (same state of charge) when they are connected in order to avoid high equalising currents.
Why is "EU" in the name?
The "EU" model is specifically certified for the European market (CE, UN38.3, MSDS) and complies with the applicable safety standards. The instructions and support are often also orientated towards European dealers.

The Deye SUN-6K-SG05LP1-EU is an ultra-modern and powerful single-phase hybrid inverter that acts as an intelligent control centre for larger photovoltaic systems. It has been developed to offer you maximum independence, efficiency and security of supply. With a high output power of 6 kW, it manages the energy flows between your solar modules, the battery storage system and the public grid. Thanks to its integrated emergency power function, you are reliably supplied with high power even in the event of a power failure.Highlights at a glanceIntelligent hybrid system: Manages PV generation, battery storage and grid consumption for maximum self-consumption.High performance: With 6 kW output power ideal for larger households, heat pumps or small commercial operations.Integrated emergency power supply: Provides an uninterruptible power supply (UPS level) in the event of a grid failure.Two MPP trackers: Enables the connection of two independent module arrays, ideal for east-west roofs or partial shading.Flexible battery connection: Compatible with a wide range of 48V low-voltage battery storage systems.Comprehensive monitoring: Integrated WLAN module for simple and intuitive system monitoring via app.Intelligent energy management for your homeThe Deye hybrid inverter is more than just a converter from direct current to alternating current. It is the brain of your energy supply. During the day, it supplies your consumers directly with solar power, while surplus energy is stored in your battery storage system for the night or for cloudy days. The energy is only fed into the public grid when the storage system is full and no consumer requires electricity. This maximises your self-consumption and significantly reduces your electricity costs.Maximum yields through flexible PV connectionThanks to the two integrated MPP trackers (Maximum Power Point), the Deye SUN-6K offers maximum flexibility when planning your PV system. You can connect two separate module strings with different orientations (e.g. east and west side of the roof) or with different module types. Each tracker optimises the output of its string individually so that you always achieve the maximum possible energy yield, even with complex roof situations or partial shading.Independence through integrated emergency power supplyA special feature of this inverter is the integrated emergency power function. If the public power grid fails, the device switches to a separate emergency power output in less than 10 milliseconds and continues to supply selected critical loads such as lighting, refrigerators or the IT infrastructure with power from the battery storage system. This switchover time to UPS level (uninterruptible power supply) ensures maximum security of supply.

It is the link between the solar modules, the battery storage system and the public grid. It decides intelligently whether the solar power generated is consumed directly, stored in the battery or fed into the grid.Who is a 6 kW inverter suitable for?A 6 kW inverter is ideal for larger single-family homes with a higher power consumption, for example due to the operation of a heat pump or an electric car. It is also suitable for small businesses or farms that want to optimise their own consumption.Which batteries are compatible with this inverter?The Deye SUN-6K is designed for operation with 48V low-voltage (LV) lithium-ion battery storage systems. It is compatible with many leading manufacturers. The exact compatibility list can be found on the manufacturer's website.Do I need additional devices for the emergency power function?The inverter has an integrated emergency power output (EPS port). To use it, the emergency power consumers to be supplied must be placed on a separate circuit by a qualified electrician and connected to this output. An additional external changeover switch is generally not required.
