Fronius Lithium Battery Module Reserve - 3.15kWh - 4,240,370

The Fronius Reserva is a DC-coupled, high-voltage lithium-ion battery designed to store solar energy with minimal losses and offer maximum efficiency, reliability and autonomy. Its modular design allows for a scalable capacity of 6.3 to 15.8 kWh - by combining two to five modules per tower - and is expandable up to 63 kWh with parallel operation of up to four towers. It is perfectly compatible with Fronius hybrid inverters, ensuring optimum system performance. Ideal for residential and industrial applications, it offers a high degree of self-consumption, efficient management of variable electricity tariffs and energy backup in the event of a grid outage.

Maximum independence

Experience maximum independence with the Fronius Standby. Thanks to DC coupling, the energy from your PV system is charged into the battery with almost no losses, ensuring maximum efficiency and power. At the same time, the high-voltage technology optimises the cost-effectiveness of your system. In combination with the Fronius GEN24 Plus, you benefit from exceptional charging and discharging performance that takes advantage of even short periods of sunshine. With lithium-ferrophosphate cells, the Fronius Reserva offers a long service life and high safety.

Features of the Fronius Lithium Battery Module Reserve - 3.15kWh - 4,240,370

Performance Assurance The Fronius battery retains at least 80 % of its original capacity after ten years, ensuring long-lasting performance.

Maximum adaptability Fronius Reserva lithium battery modules are easily stacked to configure towers with capacities between 6.3 and 15.8 kWh. To increase storage capacity, it is possible to connect up to four towers in parallel and reach up to 63 kWh, without requiring additional components such as interconnection boxes.

Status display Through the battery status display you can see important information such as the charge level or battery status, which makes it easy to monitor the system.

Compact design Designed to fit into any environment, the Fronius Reserva combines compact size with high durability (IP65, -20 to +55 °C), making it ideal for installations in confined spaces such as garages or machine rooms, with no loss of performance.

Ideal for variable electricity tariffs With the Fronius Reserve, you can make the most of variable electricity tariffs. With the Solar.web Premium Energy Cost Assistant (ECA), the battery charges when electricity prices are low and supplies you with energy when the tariffs rise again - efficiently and cost-effectively.

Emergency power The Reserve has emergency power, so in the event of a power failure it can start, charge and discharge. In this way, it maintains its autonomy and reliability of supply even in emergency situations.
