Store Solar Energy
for Flexible Use

Solar power, even if the sun is not shining
Use solar power, even at night
A photovoltaic system produces electricity during the day when the sun is shining. In a typical household, however, the electricity demand is highest in the morning and evening hours. This is precisely when little or no electricity is being produced.In order to use as much solar power as possible instead of expensive electricity from the public grid, you can either postpone your energy consumption until the sun is shining, or store solar energy for later.

Backup power supply in the event of a blackout
Most photovoltaic systems are automatically disconnected from the grid and switched off during a grid blackout.
However, with an emergency-capable hybrid inverter, a battery storage system and a grid switching device, the PV system also runs when it is disconnected from the grid, and you can continue to supply yourself with your own energy during a power outage.

How a photovoltaic system with storage unit works
In this way the energy from your own roof can be used throughout the household.Keep an eye on your photovoltaic system at all times
With the free Fronius Solar.web monitoring tool, you can keep an eye on your energy yield and consumption at all times and get the most out of your photovoltaic system.
- Ensure functionality
- Shorten the payback period
- Expose energy guzzlers
- Analyse and optimise energy consumption
- Keep the system up-to-date
- Save more money with individual extensions
- Extend warranty free of charge

Fronius UP.storage
For those who still can’t decide: With the Fronius UP.storage* software upgrade for the Fronius GEN24, the existing device can be retrofitted with a battery connection at any time, including the Full Backup option.**
* Available in the Fronius webshop in selected countries.
** Not available for the Fronius Symo GEN24 3.0–5.0 Plus.

What capacity of storage system do I need?
The size, or capacity, of a storage unit is calculated based on your individual energy requirements. With the right storage unit, you can increase your self-sufficiency with solar energy to up to 85%,meaning that energy costs decrease and your energy independence increases.
The following rule of thumb applies when selecting the correct storage unit:


High quality, worthwhile investment
What makes a good energy storage system?
Owing to our years of experience, we know what really matters when it comes to photovoltaic systems with storage units.
Particularly important is the interaction between storage unit and inverter. Only when these two components work together smoothly can you use your own solar power in a truly flexible and efficient way. This particularly applies n the event of a blackout.
Fronius inverters in combination with high-quality storage units enable flexible charging management: Thanks to the possibility of parallel energy flows, for example, the household can be supplied with solar power and a storage unit can be charged at the same time. You also have the choice of two backup power variants and can expand your Fronius system on a modular basis at any time. Your PV system with storage unit is therefore the perfect basis for a sustainable energy supply.
