Fronius' own high-voltage battery, designed as a matched partner for GEN24 Plus hybrids.
Supplied and installed by our CEC-accredited team across Queensland.
Reserva is Fronius' own high-voltage LFP battery, designed as a matched partner for GEN24 Plus (and Verto Plus) hybrid inverters. One tower holds 2 to 5 modules, for 6.3 to 15.8 kWh. Up to four towers can be combined for 63 kWh, or 38.4 kWh on a single-phase system.
How it works, simply: during the day, surplus solar charges the battery instead of being exported for a few cents. In the evening the battery powers your home before you draw from the grid. LFP (lithium iron phosphate) chemistry is known for thermal stability and long cycle life.
It suits homeowners who want an all-Fronius system with one warranty partner and Solar.web monitoring, and those who value backup, since Fronius specifies backup and black-start capability.
For Queensland conditions: the manufacturer specifies an operating range of -20 to +55 °C, and its enclosure rating is Indoor/outdoor (IP 65). In hot climates many systems reduce output at the top of their range, so we install out of direct afternoon sun with clearance for airflow wherever possible. With storm season bringing outages, the backup set-up (which circuits stay on) is something we'll design with you.
Designed alongside Fronius' hybrid inverters for straightforward commissioning and monitoring in Solar.web.
Two to five modules per tower, and up to four towers per system.
Fronius lists operation from −20 to 55°C, in an IP65 enclosure.
It can restart the system from the battery after an outage, even without solar.

Products from other categories that work well alongside the Reserva.
Reserva is designed for Fronius GEN24 Plus and Verto Plus hybrid inverters.
The manufacturer warranty is 10 years, with battery capacity remaining at end of warranty: 70%; warranted throughput: 39,140. Terms may require product registration. We register it for you.
The manufacturer lists Indoor/outdoor (IP 65). In Queensland we still avoid direct afternoon sun where possible, because heat can reduce performance, and we'll recommend the best spot during the site visit.
