Product description
Product description
The Fronius Reserva Module 3.15 kWh is a battery module based on lithium iron phosphate (LFP) cells and is the basic unit of the Fronius Reserva high-voltage energy storage systems. 2 to 5 modules can be installed in a tower, allowing the total storage capacity to be flexibly scaled between 6.3 and 15.8 kWh. Multiple towers can be connected, so the system can be expanded to meet higher energy demands.
Each module provides a usable capacity of 3.15 kWh and has a nominal voltage of 102.4 V. For operation, a Fronius Reserva BMS control unit is required in each tower, which monitors the modules and connects them to the hybrid inverter. The direct DC connection with the Fronius GEN24 Plus and Verto Plus hybrid inverters enables low-loss energy storage.
The module is IP65 rated, making it safe for both indoor and protected outdoor installation. Reliability is guaranteed by long-life LFP cells and international safety certifications (IEC62619, VDE 2510-50, UN38.3).

How do I choose the right battery?
How do I choose the right battery?
The most important thing is that the battery fits your inverter and the performance of your system. It is worth considering how much capacity (kWh) you need and whether you want to expand the system later.
Always check the inverter's technical data sheet, as it will tell you which batteries it is compatible with. For example, Huawei inverters only work with Huawei batteries, while Deye inverters can be connected to multiple manufacturers, offering a more flexible solution.
How do inverter types differ?
How do inverter types differ?
The lifespan of modern lithium batteries is usually 10–15 years, depending on usage and temperature conditions.
Manufacturers typically give an expected lifespan of 6,000–8,000 charging cycles – this can mean up to a decade and a half, assuming one cycle per day.
What happens in the event of a power outage?
What happens in the event of a power outage?
If the inverter supports backup (stand-alone) operation, it will automatically switch to the battery during a power outage, so the most important consumers continue to operate.
It is important to know that if there is no backup function, the system will completely stop in the event of a power outage, even if the solar panels are producing. This is because most on-grid inverters cannot operate without mains voltage for safety reasons, so they cannot supply power or charge batteries.
What warranty does the battery have?
What warranty does the battery have?
Depending on the manufacturer, batteries come with a 5 or 10 year warranty, and for some models this is also tied to the number of cycles. We indicate the exact warranty period on each product page, so you can always see how long the manufacturer's warranty lasts before you buy.
What happens if the battery fails?
What happens if the battery fails?
If the battery is not working properly, it is a good idea to first have the problem diagnosed by a professional to rule out incorrect setup or installation. It is possible that the problem is not with the battery itself, but with a non-activated function or communication setting.
If it is proven that there is indeed a problem with the product, you should contact the manufacturer's or distributor's customer service, who will assist you in the troubleshooting process and the warranty administration process.
