Integrated heating technology: No more winter limitations

The key feature of the EL-A05 is its optional heating function*. Unlike standard lithium batteries, which lose performance or refuse to charge below 0°C, this system is a game-changer:

• Performance in extreme cold: Thanks to its thermal system, it supports a discharge range from -20°C to 55°C.
• Active thermal protection: The heating system maintains the cells at an optimal temperature, thereby extending their lifespan even in an uninsulated garage or outdoors.
• Safe charging: The system ensures that charging begins under ideal safety conditions for LiFePO4 chemistry.
• Unrestricted installation: Its IP65 rating, combined with the heating system, allows for safe installation outdoors or in uninsulated areas such as a garage, basement or utility room.

Important note: The built-in preheating function can only be activated with certain specific inverters (notably the Deye range). Please check your inverter’s compatibility to benefit from this option in cold weather.

Power and responsiveness: Support for 1C rate

The Leapton EL-A05 is not just a battery, it is a dynamic power source:

• 1C discharge rate: At a temperature of 25°C, it can handle a maximum charge and discharge current of 100A.
• 5.12 kW power: It is capable of delivering its full capacity instantly to meet the needs of the most power-hungry appliances in your home.
• Energy efficiency: The system boasts a conversion efficiency of 90%.

Longevity and safety with LiFePO4 chemistry

Invest for the long term with one of the most stable chemistries on the market:

• Superior cycle life: Offers over 6,000 cycles (at 25°C), representing more than 15 years of daily use.
• Integrated Smart BMS: Its intelligent management system (BMS) monitors each cell in real time for total protection against overvoltage and overheating.
• Natural cooling: Its natural convection system ensures completely silent operation, ideal for living areas.
• 10-year warranty: Leapton Solar is committed to the durability of its product with a 10-year manufacturer’s warranty.

Leapton Prismatic Cell Technology: Performance and Safety

Leapton batteries integrate the latest generation of Lithium-Iron-Phosphate (LiFePO4) cells in a prismatic format. Unlike standard batteries, this high-end architecture is specifically designed for intensive residential and industrial energy storage.

Maximum Safety and Thermal Stability

Leapton's prismatic design uses a rigid aluminum casing that provides superior protection against mechanical stress.

• Ultra-Stable Chemistry: LFP technology is the safest on the market, virtually eliminating any risk of fire or thermal runaway.
• Pressure Relief Valves: Each cell is equipped with an individual safety vent for optimal management of internal pressure.

Exceptional Lifespan (6000+ Cycles)

Thanks to an optimized internal structure, prismatic cells undergo less physical stress during charge and discharge cycles.

• Increased Longevity: Benefit from a useful lifespan exceeding 15 years in daily use.
• Low Internal Resistance: Maximum energy efficiency with minimal heat loss.

Compact Design and High Density

The rectangular format of prismatic cells allows for assembly without wasted space.

• Space Saving: Greater storage capacity in a more compact and elegant casing.
• Uniform Cooling: The large flat surface of the cells allows for homogeneous heat dissipation, ensuring your battery remains efficient even under heavy loads.

Why choose Leapton Prismatic cells?

1. Reliability: Fewer internal connections than cylindrical cell packs, reducing potential points of failure.
2. Eco-friendly: Without cobalt or nickel, our cells are more environmentally friendly and easier to recycle.
3. Sustainable Investment: One of the lowest costs per cycle on the market thanks to extremely slow degradation.

We recommend Leapton prismatic cells to our customers seeking the best safety/longevity ratio. It is a robust technology that makes no compromises on safety, ideal for maximizing solar self-consumption.

IP65 protection rating: Hassle-free installation

Its robust design allows for total flexibility during installation:

• Certified waterproofing: Thanks to its IP65 rating, it is fully protected against dust and water splashes.
• Versatile installation: It can be wall-mounted indoors or outdoors.
• Natural cooling: Its natural convection system ensures completely silent operation, ideal for living areas.

Scalability and smart connectivity

The EL-A05 adapts to your changing energy needs:

• Massive parallelisation: You can connect up to 15 units in parallel to increase your storage capacity.
• Extensive compatibility: Works with hybrid and retrofit inverters, in single-phase or three-phase configurations.
• Multi-protocol communication: Features RS485, RS232 and CAN ports for seamless communication with your photovoltaic system.

Why does the Leapton EL-A05 exceed industry standards?

1. Exceptional lifespan (6000+ cycles)

Fitted with highly stable LiFePO4 (LFP) cells, this battery delivers over 6,000 cycles (at a temperature of 25°C). This exceptional longevity ensures that efficiency is maintained at 80% of the initial capacity after 10 years of use. For the user, this represents over 15 years of reliable storage before reaching the standard wear threshold.

2. Intelligent management with the Smart BMS

The integrated Smart BMS (Battery Management System) is not just a safety feature; it is the true brain of your energy system.

• Total safety: It ensures constant monitoring of voltage, current and temperature for risk-free use and increased durability
• 1C Performance: Unlike many batteries limited to 0.5C, the EL-A05 supports a 1C charge and discharge rate at 25°C. This allows it to instantly unleash its full 5.12 kW power to meet the power demands of your most power-hungry devices.

3. All-Weather Technology: Heating function and IP65

The distinctive advantage of the Leapton EL-A05 is its ability to withstand harsh environments thanks to its heating function.

• Frost resistance: Whilst cold temperatures often cripple lithium batteries, the EL-A05 remains operational with a discharge range down to -20°C.
• Outdoor Protection (IP65): Certified to IP65, it is completely dust-tight and protected against water splashes, allowing for worry-free installation outdoors or in unheated premises.

4. Modularity and full compatibility

The EL-A05 has been designed to evolve seamlessly with your energy needs:

• Massive parallel connection: Thanks to its optimised design, you can connect up to 15 units in parallel, achieving an impressive storage capacity of over 75 kWh.
• Hybrid inverter compatibility: It integrates seamlessly with hybrid inverters (such as WKS, Deye, etc.) and ‘retrofit’ systems, whether single-phase or three-phase.
• Advanced communication: It features RS485, RS232 and CAN ports for seamless synchronisation with the majority of communication protocols on the market.

Leapton Solar: why Japanese heritage makes the difference

Leapton Solar is a Japanese manufacturer specialising in photovoltaic panels and storage systems. Whereas many batteries on the market are generic products from anonymous manufacturers, the EL-A05 benefits from a Japanese design and quality control process — a rigour that translates into increased long-term reliability and consistent performance cell by cell.
