With the Reserva battery system, our partner Fronius is rounding off its product portfolio and can now offer a complete PV system from a single source. The components are perfectly matched to ensure seamless configuration and installation, as well as efficient operation.
The Fronius Reserva can consist of two to five modules with 6.3 to 15.8 kWh per tower. By connecting four towers in parallel, the system can be expanded to up to 63 kWh. DC coupling enables maximum efficiency and, thanks to the lithium iron phosphate cell chemistry, the battery system is particularly durable and reliable.
For optimal charging and discharging performance, the Fronius Reserva can be optimally combined with the hybrid inverters GEN24 Plus and Verto Plus (coming soon). Thanks to the Solar.web monitoring platform, all information and processes can be kept in view at all times.
