Reserva, the Fronius storage solution

Premium storage, built to integrate

Fronius Reserva is a scalable high-voltage lithium iron phosphate (LFP) battery, engineered to pair directly with the Fronius GEN24 Plus inverter for single and three phase homes. One brand, one system, one point of contact.

  • DC-coupled efficiency

    Direct DC coupling with the Fronius GEN24 Plus keeps more of every kilowatt on its way to and from the battery.

  • One system, one contact

    Battery, inverter and management from Fronius, backed by the Solar Juice wholesale team, means streamlined service.

  • Modular and scalable

    Stackable high-voltage LFP modules scale from 3.15 kWh up to 63 kWh as your customer needs grow.
