Built for Fronius

DC-coupled to a Fronius hybrid

Reserva Pro is designed for Fronius GEN24 Plus and Verto Plus hybrid inverters, for homes, businesses and farms with higher energy demands.

Paired with a Verto Plus, the DC-coupled system charges and discharges at up to 28.3 kW, enough for larger loads and high consumption.

Fronius inverter models and ratings are on our Fronius inverter page.

Highly scalable

12 to 32 kWh a tower, 128 kWh in all

Each tower takes three to eight battery modules for 12 to 32 kWh of storage, 11.9 to 31.9 kWh of it usable. Up to four towers connect in parallel, taking the system to 128 kWh.

Backup and black start

Restarts on its own when the grid is down

With a compatible Fronius hybrid inverter the system supplies backup power and can restart autonomously without grid supply.

Durable LFP cells, with the cells and modules manufactured in Europe to Fronius' quality and safety standards.

Monitoring

One Fronius system, one view

Fronius Solar.web and Fronius' energy management tools monitor and optimise the battery within the complete Fronius ecosystem.

How the rebate estimate works

The federal Cheaper Home Batteries Program pays through STCs. Usable capacity counts in three tiers: the first 14 kWh in full, the next 14 kWh at 60% and the next 22 kWh at 15%, up to 50 kWh. That figure is multiplied by a factor that steps down every six months: 6.8 for installs from 1 May to 31 December 2026, then 5.7 from 1 January 2027. Batteries under 5 kWh usable are not eligible.

Estimate only. The final rebate depends on install date, the battery's CEC-listed usable capacity, approved equipment, accredited installation, solar eligibility and the STC price at the time. Your quote will confirm the exact amount.
