Product description
Product description
The three-phase inverters of the Fronius Eco series (25 and 27 kW) are specifically designed for larger residential, community and smaller industrial solar systems. Thanks to their lightweight design and the SnapINverter mounting system, the devices can be easily installed, both indoors and outdoors.
The series is available in two versions:
- Fronius Eco Light (RS485) – with basic data communication and a cost-effective design.
- Fronius Eco Wlan (LAN/WLAN) – with integrated web connection, online monitoring and data logging.
Both versions offer outstanding efficiency of up to 98.3% and support 200% oversizing for flexible system design. Safety is also a priority in the inverters: DC isolator, integrated string fuses and reverse polarity protection are standard.
The Eco series is also Smart Grid ready, allowing it to seamlessly integrate into modern energy management systems. IP66 protection and controlled air cooling ensure long-term reliability in outdoor conditions.
- 25–27 kW power range, 3 phases
- SnapINverter mounting system for quick installation
- Light (RS485) and Wlan (LAN/WLAN) versions
- 98.3% maximum efficiency, 200% scalability
- Built-in DC isolator and string fuses
- Smart Grid Ready, for modern energy management
The Fronius Eco series is the ideal choice for any project where high performance, quick installation and easy system integration are key.

How do I choose the right inverter?
How do I choose the right inverter?
When choosing an inverter, it is worth considering the power of the solar panels, their voltage range, the number of phases in the system (single- or three-phase), and whether you plan to expand with batteries in the future.
In the case of three-phase systems, a distinction must be made between symmetrical and asymmetrical inverters. The symmetrical type distributes the power equally across all three phases, which is an advantageous solution for simpler networks. The asymmetrical inverter, on the other hand, can regulate the power differently per phase, thus adapting more flexibly to the real consumption pattern of the house - for this reason it is usually the more practical and efficient choice for domestic systems.
When is it worth choosing a hybrid inverter?
When is it worth choosing a hybrid inverter?
It is worth choosing a hybrid inverter if you want to expand the system with battery energy storage in the future or if you want to provide the house with protection against power outages.
Hybrid models are more expensive, but offer a more flexible solution in the long term, as they can be easily integrated into the existing system later.
What happens in the event of a power outage?
What happens in the event of a power outage?
During a power outage, traditional grid-fed inverters automatically shut down to prevent power from being fed back into the utility grid for safety reasons.
Hybrid inverters, on the other hand, can operate in stand-alone, so-called backup mode, if a battery is also connected to the system. In this case, the inverter disconnects itself from the grid and uses the energy stored in the battery to continue supplying designated consumers in the house, such as lighting, a refrigerator or a router. As soon as the grid voltage returns, the inverter automatically returns to normal operation and begins recharging the battery.
What warranty does the inverter have?
What warranty does the inverter have?
The warranty is typically 5-10 years, depending on the manufacturer and model. Some manufacturers also offer extended warranties with registration. The exact duration is listed on each product page, so it's worth checking before purchasing.
What happens if the inverter fails?
What happens if the inverter fails?
As a first step, it is always recommended to diagnose the fault, because often the problem is not related to the inverter, but to the settings or the communication module.
If there is an actual failure, the distributor or manufacturer's service partner will assist with the repair or replacement process, within or beyond warranty.
