About Fronius, Solar Batteries

Fronius solar batteries review

Fronius is one of the world's longest established solar brands and the company's inverters are widely regarded as among the best, if not the best, in the world. Fronius has also put its toes in the water in relation to energy storage.

Fronius was founded in 1945 in Pettenbach, Austria, and originally produced battery chargers and welding transformers; which it continues to produce today. The company has also been producing solar components since 1992 - well before the PV revolution as we know it began.

The Fronius Solar Battery is the German company's only current contribution to the home energy storage arena. It uses lithium-iron phosphate storage technology - the safest of currently commercially available home energy storage chemistries. 

The Fronius Solar battery starts out at 4.5kWh, but can be easily expanded to as much as 12kWh capacity (9.6kWh usable) using 1.5kWh modules. The power rating is good at 4kW steady for the 12kWh configuration.

The battery can be purchased as part of the Fronius Energy Package, which also includes Fronius Symo hybrid inverter and smart meter.

Among some of the disadvantages of the Fronius battery are its rather high price, it can only be installed indoors, it has a comparatively short warranty (even though it has a long expected design life) and it can only be used in three-phase homes.

Also, the smart meter included as part of the Fronius Energy Package doesn't compare well against the features and capabilities offered by Solar Analytics; so you may want to give that component a miss.

The Fronius solar battery warranty isn't much chop given this is a quality product from a quality company - it's just 5 years if the battery purchase is registered with Fronius within 30 days, otherwise only 2 years. It's certainly good incentive to register quick-smart, but most good battery manufacturers offer a 10-year warranty these days. Still, whether some of those manufacturers will still be around in 5 years let alone 10 remains to be seen, while Fronius is very likely to be.
