INTRODUCTION
Fronius Reserva Australia Home Battery
The Fronius Reserva is a cutting-edge, reliable choice for homeowners looking to improve their solar efficiency with a home battery. It’s an ideal solution if you already have a Fronius inverter, as the DC-coupled, high-voltage battery can easily complete your system (or complement it if you’re starting from the ground up). The DC-coupling means that you can connect directly to an inverter with fewer conversions, reduced energy loss, and increased efficiency.
The battery is intended to fit seamlessly with the Fronius GEN24 Plus hybrid solar inverter with long-term viability. The scalable design is a convenient choice for securing your home against blackouts and increasing your energy independence by simply reducing your energy bills. You can start with a single tower that ranges from 6.31 – 15.79 kWh and connect them in parallel for an impressive 63 kWh of usable energy.
Smart monitoring means you can track every part of your setup, including the inverter, battery, and EV charger, from one convenient app to get a full overview of your solar energy efficiency. The Reserva comes with a 10-year product warranty and guarantees that the battery will retain at least 70% of its usable capacity during the warranty period.
