Fronius' state-of-the-art 3-phase inverters convert DC electricity from solar panels into AC power suitable for household appliances with an efficiency of up to 97%.

The inverter is the heart and brain of the photovoltaic system, enabling the efficiency of the solar panels' power output and the security of the entire energy system.
The electricity produced by a 3-phase inverter can be fed to all electrical appliances in the home.
Feeding electricity into the public distribution grid is less cost-effective than using it for your own needs.
The amount of electricity fed into the distribution grid can be minimised by keeping all three phases on when the PV system is generating electricity. Appliances requiring high electrical power, such as hot water heaters, heat pumps, stoves and cookers, are usually connected to all three phases of the grid.

System power optimisation
Intelligent monitoring software enhances the performance of solar panels by monitoring parameters such as current and voltage values to ensure optimum power output.

Safe power generation
The inverter has a built-in cooling feature to prevent the system from overheating.
The automation also controls the grid frequency and reduces the output as needed.
In the worst case, the inverter can disconnect the solar power system from the home's electrical grid.

Fronius Smart Meter - smart meter
With the optional Smart Meter, you can monitor and record your electricity consumption with great accuracy. Fronius inverters can manage your household's electricity load and ensure that as much of your own solar power as possible is used. They are also easy to integrate into popular smart home systems.

Monitoring portal - Solar.web Classic
Take advantage of a comprehensive control portal for configuration, monitoring, analysis and visualisation. Install the useful application on your phone or tablet. Up-to-date information is available at any time, clearly presented. If you wish, the software can automatically notify an authorised installer if problems occur. In the best case, faults are fixed before you even know they exist.

Fronius extended warranty - www.solarweb.com
Free registration within 30 months of delivery extends the warranty to 7 years.

Backup power
For safety reasons, a photovoltaic system connected to the public grid will be switched off during a power outage.
