Fronius GalvoSnapINverter mounting system
SmartGridReady The future-proof inverter for small self-consumption systems.

With power categories ranging from 1.5 to 3.1 kW, the Fronius Galvo is perfect for households – and is especially suitable for self-consumption systems. The integrated energy management relay allows the self-consumption component to be maximised. A host of other smart features make the Fronius Galvo one of the most future-proof inverters in its class: for example, the integrated datalogging, the simple connection to the internet by WLAN, or the plug-in card technology for retrofitting additional functions.

/  Suitable for all module technologies due to galvanic isolation
/  New hinged system for quick and easy installation
/  Low weight and compact size
/  For indoor and outdoor mounting (high protection class IP 65)

Note: Product availability and data will vary by location. Please visit your specific country’s website for available products and information.

SnapINverter mounting system

The special feature in the design of our devices is that the connection compartment is separate from the power stage set compartment. They are installed separately. The connection area and all its cabling is fitted to the wall first. The power stage set compartment is fitted afterwards. The innovative SnapINverter mounting system makes installation and servicing extremely user-friendly. The inverter is simply placed in the wall bracket and then secured. It is not necessary to remove the entire inverter for servicing, just the power stage set compartment. All the cabling, settings and configurations remain in place.

Automatic HF transformer switchover

Fronius transformer inverters use a high-frequency (HF) transformer. The automatic transformer switchover facility produces three efficiency peaks. The result: a constant level of efficiency across the entire input voltage range, resulting in higher yields. Other advantages of HF transformer technology are the compact, lightweight design and safety as a result of the electrical isolation.

Integrated WLAN interface

Simple, user-friendly system monitoring is very important to Fronius. With the Fronius Datamanager, we are the first inverter manufacturer to offer a WLAN interface in the inverter itself. The inverter is connected to the internet without additional cabling and grants you the perfect overview of how the PV system is operating.

Smart Grid Ready

Fronius inverters are ready for the Smart Grid of tomorrow. The inverters are optimally equipped to meet the technical requirements of grids in the future. A series of smart functions, known as Advanced Grid Features, are built into the devices. These include a number of control functions for optimum feed-in of reactive power and effective power. These functions are designed to enable stable grid operation even when the PV system density is very high and to prevent unwanted interruptions to feed-in and associated yield losses. Fronius inverters therefore help to guarantee the yield of a PV system.

Zero feed-in

Today, an increasing number of grid operators in various countries are stipulating a PV power feed-in limit as a precondition before a system is connected to the grid. With dynamic power reduction, Fronius is offering a solution for optimum feed-in management. The inverter supplies the household consumers with energy first and then reduces the system output to the maximum energy feed-in permitted by the grid operator. With Fronius inverters, zero feed-in is also a possibility thanks to this function, meaning that no PV power is fed into the grid. The relevant requirements of the grid operator can be fulfilled by simply enabling a setting on the inverter's web interface.
