Low voltage

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 glanceMassive 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 applicationThe 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 instructionsWeight 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. Characteristics ModelFelicity Solar FLA48230-EU Technology**LiFePO4** (Lithium Iron Phosphate) - Safe & Durable Nominal voltage**51.2 V** (standard low voltage system) Capacity**230 Ah** Energy content**11.77 kWh** (Marketed as ~11.8 kWh) Usable energy (DOD)approx. 90% - 95% (depending on inverter setting) Lifespan**≥ 6000 cycles** (at 25°C, 80% DOD) Communication**CAN / RS485** (Compatible with Deye, Growatt, etc.) Mounting**Wall mounting** (bracket included) or stand Weightapprox. **100 - 105 kg** (Attention: Very heavy!)

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. Scope of delivery: Felicity Solar FLA48230-EU (11.8 kWh LV battery storage) 1 x Felicity Solar FLA48230-EU battery moduleA standing 51.2V LiFePO4 energy storage system with a capacity of 230 Ah (11.77 kWh) and integrated battery management system (BMS).1 x set of DC power cables (power cable)A pair of high-current-resistant cables (plus and minus) for the electrical connection of the storage system to the low-voltage inverter.1 x BMS communication cableA pre-assembled data cable (RJ45) for communication between the battery and the inverter via CAN or RS485 interface.1 x earthing cableA yellow-green protective earthing cable for safe earthing of the battery housing.1 x wall mounting set / anti-tilt deviceMounting accessories for fixing the housing to the wall to prevent the upright storage system from tipping over.1 x mounting kit (screws and accessories)All small parts and screws required for installation and electrical connections.1 x User manualA technical manual with installation instructions, pin assignments for various inverters and safety instructions.
