Advantages at a glance
Maximum single tower
8 modules is the maximum for one tower. For more capacity, up to 4 towers can be operated in parallel – a total of 127.6 kWh.
LFP cell chemistry
Lithium iron phosphate is thermally stable and cobalt-free – the safest cell chemistry commonly used in homes.
IP65 – also outdoors
Indoor and protected outdoor areas, -20 to +50 °C, up to 2,000 m above sea level. No separate technical room required.
High-voltage technology
566.72 V nominal voltage and 50 A maximum output current – fewer conversion losses than with low-voltage systems.
10 year warranty
Fronius guarantees 80% of the originally usable capacity (State of Health) after 10 years.
Made in Europe
Fronius develops and produces in Upper Austria – relevant for the Made in Europe bonus of the EAG funding.
Warranty & Longevity
Funding in Austria
The prerequisite is that the product is listed on the White List of the EAG processing body and that the bonus is applied for together with the main application. Storage systems are also only subsidized in conjunction with a newly built or expanded PV system. Non-binding information, as of August 2026. Funding rates, conditions and product listings may change at any time – without guarantee and without claim to a funding commitment. Binding information is provided exclusively by the EAG processing body.

Frequently asked questions
What does LFP mean and why this cell chemistry?
LFP stands for lithium iron phosphate. These cells do not contain cobalt, are significantly more thermally stable than NMC cells, and tolerate many charging cycles. For a storage unit that is charged and discharged daily for years and is located in a residential building, this is the safest widespread design.
How much do 31.9 kWh provide in everyday life?
31.9 kWh is the largest single-tower stage and suits an annual consumption of 10,000 to 14,000 kWh – large house with a heat pump, pool and several electric cars, or a commercial business with a high base load.
Is there funding for the storage system?
The EAG investment grant supports electricity storage systems in 2026 with €150 per kWh of usable capacity, with a Made-in-Europe bonus of €165 per kWh. Up to 50 kWh and a maximum of 30% of the investment costs are subsidized, only in conjunction with a new or expanded PV system. All information is non-binding – binding information is provided by the EAG processing body.
Is more than 31.9 kWh possible?
Yes, but not in one tower. 8 modules is the maximum per tower. In addition, up to 4 towers can be operated in parallel, totaling up to 127.6 kWh – interesting for commercial use and large peak loads.
Can the storage system be placed outdoors?
The Reserva Pro is IP65 protected and approved for indoor and protected outdoor areas, at -20 to +50 °C and up to 2,000 m above sea level. Protected means: no continuous direct rain and no blazing sun, for example under a canopy or in a carport.
Who is Fronius?
