Product description
Product description
The Fronius Reserva BMS (Battery Management System) is the central control unit of the Reserva battery tower. It is responsible for supervising the operation of the battery modules, monitoring the condition of the cells and ensuring communication with the Fronius hybrid inverters. Up to five modules can be connected to a BMS unit, and a separate BMS is required for each tower.
The control unit ensures safe charging and discharging processes, monitors cell temperature and voltage, and optimizes the energy flow. Thanks to compatibility with Fronius GEN24 Plus and Verto Plus hybrid inverters, the system operates directly on the DC side, minimizing conversion losses.
The IP65 protection and compact size allow for indoor and protected outdoor installation. The standard RS485 communication interface ensures easy integration and reliable data transmission.
Main features in brief:
- Battery controller for Fronius Reserva modules
- Manage up to 5 modules per tower
- Each tower requires a separate BMS
- Compatibility: Fronius GEN24 Plus and Verto Plus inverters
- Safety functions: cell voltage and temperature monitoring
- Optimized energy flow and protection
- IP65 protection, indoor and protected outdoor installation
- RS485 communication interface
What makes the Fronius Reserva BMS unique is that it is the safety and communication center for the operation of the entire battery system – without it, the modules cannot be operated.

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.
