From pv magazine Germany.

Sonnen started its new three-phase “Sonnenbatterie 10 Performance” on Wednesday. Currently only available for the German market, the storage system has 8 kilowatts of charging and discharging power, according to the German manufacturer. The storage capacity can reach up to 55 kWh.

The company also offers an emergency power box called “Sonnen Protect 8000”, with which new storage systems can be made network-independent. This means that if the power supply fails over a longer period of time, the “Sonnenbatterie 10 Performance” can set up its own power grid in the household. This means that the power supply can be ensured solely by the photovoltaic system and the battery. The emergency power box is available as both an AC and a DC version.

“With the flexible AC or DC-side island function, we would like to make an offer to customers who want even more independence and maximum security in the event of a power failure,” said Sascha Koppe, Country Director DACH at Sonnen. This is an alternative to the Solar Plus storage systems currently available on the market.

Sonnen also offers the “sonnenDC Module” function. This means that the AC version can be converted into a hybrid version with which the photovoltaic system can be connected directly. This provides the storage system with a black start capability. According to the manufacturer, only a few steps are required for the installer. This means that the “10-power solar battery” is also suitable for small businesses and agricultural companies that require three-phase electricity and high storage capacities.

Sonnen relies on the proven lithium iron phosphate technology for its new storage system. The company gives a 10-year guarantee on all parts and a service life of 10,000 charging cycles for the entire system.
