Frequently Asked Questions

What is a sonnenBatterie?: The sonnenBatterie is a fully integrated energy storage solution with perfectly synchronized components including battery modules, integrated bi-directional inverter and smart energy management system – supplied in one easy-to-install box. Much more than just a battery, the sonnenBatterie enables users to change the way they manage and control their energy.
The latest (ninth) generation of the sonnenBatterie series was launched in Q1 2018 throughout sonnen’s global markets. It is a single-phase battery storage system which is available as both AC-coupled (eco 9.43) and DC-coupled (hybrid 9.53) options providing the optimum solution for both new and existing PV installations.
How much electricity can a sonnenBatterie 10 store?: It depends on which size of system you choose. A sonnenBatterie 10 can be sized either as an 11 kWh or 22 kWh unit. This means that you can size the system to suit your needs and you won't have to worry about future energy demands, because you can simply add more capacity at a later date.
What warranty does the sonnenBatterie have? How does it compare?: The sonnenBatterie comes with a market-leading warranty of 10 years or 10,000 charge cycles, and a battery service life of 20 years. The performance guarantee states that the battery will be not less than 70% of its installed capacity after 10,000 cycles. This is a market-leading warranty which is founded on the superior battery chemistry that we use in the sonnenBatterie to give a longer service life.
Is the sonnenBatterie 10 AC- or DC-connected?: The sonnenBatterie 10 is available as an AC connected system, allowing for a seamless integration into any existing solar PV system. However, we have a sonnenBatterie hybrid which is our DC system for homes that are thinking of installing new solar panels.
