FRONIUS Battery RESERVA solar panel - Module - 4.230.370

The battery module Fronius Reserva 3.15 kWh is a high-voltage storage element intended for systems Fronius Reserva in modular configuration. Based on lithium iron phosphate (LFP) technology, this module integrates into a scalable architecture allowing the storage capacity to be precisely adapted to the energy needs of the site.

Each module provides a nominal capacity of 3.15 kWh and can be stacked 2 to 5 units per battery pack, offering a total capacity of between 6.3 and 15.76 kWh per tower. High-voltage DC coupling with inverters Fronius GEN24 and GEN24 Plus allow direct use of photovoltaic energy, including outside of production periods, with optimized efficiency.

The system Fronius Reserva allows for various backup power scenarios, with the possibility of simultaneous charging and discharging in backup mode, depending on the chosen configuration. This approach promotes high rates of self-consumption and energy self-sufficiency, while maintaining consistent management of electrical flows.
The module comes with a 10-year manufacturer's warranty.
