Backup power function – independence, even in the event of a power outage

Photovoltaics with backup power function

PV system owners want maximum independence with their PV system – even during power failures and grid disturbances. In order to provide the household with an optimal supply of energy during a power outage, Fronius hybrid inverters have an integrated backup power function that can be perfectly adapted to various customer needs.

Advantages of a photovoltaic system with backup power function

If you were to sum up Fronius backup power options in just a few words it would be maximum independence and flexibility. Maximum independence thanks to the three-phase backup power supply, which is integrated as standard in all hybrid inverters and automatically supplies the household with energy via a PV generator and battery during a grid failure. Maximum flexibility thanks to Multi Flow Technology, which enables the battery to continue to be charged via the PV generator during a power failure and at the same time supply the household with electricity.

Basic backup power supply & complete independence

Basic backup power supply with the PV Point

The Fronius GEN24 Plus inverters feature an innovative basic backup power supply with no need for any complex additional installation work. This is a backup power socket, which can be used to operate single-phase loads up to 3 kW.

This enables system owners to charge their phone or laptop with ease, ensuring that they remain contactable and up-to-date with the latest information during a power outage.

Advantages

Automatic activation in the event of power failure
No complex additional installations required
Supply of 1-phase loads up to 3 kW

Full Backup option for maximum independence

With the Full Backup option, maximum independence and flexibility can be achieved with the Fronius GEN24 Plus hybrid inverter. In the event of a power failure, the inverter switches to emergency power mode using a grid switching device, in either a fully automatic or manual process. This supplies the entire household with energy via the photovoltaic system and the battery. This makes it possible to supply both smaller single-phase and larger loads like electric cookers or heat pumps.

A battery storage system and a switchover device for safe network disconnection are required for this. Thanks to integrated Multi Flow Technology in the hybrid inverter, the loads can be supplied by the PV system and the battery during a grid failure. If sufficient PV energy is being generated, it is also possible to supply loads and charge the battery simultaneously in the event of a power outage.

Advantages

Supplying the entire household including large loads such as heat pumps
Grid switching device tailored to customer needs for switching to emergency power mode
Efficient energy flows also possible in a backup power situation

How it works at a glance

In the case of the PV Point backup power variant, a socket is connected to the inverter. This socket can be used to operate household electrical appliances in the event of a power outage.

If a grid failure occurs with a Full Backup option in place, the building is disconnected from the public grid. The electricity required is supplied to the household from the photovoltaic system and the battery storage system.

Safely supplied in the event of a power outage

“We want to supply our entire household with PV electricity in the event of a power outage. It was therefore clear that we were looking for an inverter that could do this. There aren’t that many that can, but we have found one in the Fronius GEN24 Plus.”

Thomas Ringer, PV system owner
