Frequently Asked Questions
No, the sonnenPro Cascade is based on the sonnenBattery 10 performance and uses the sonnenBattery's smart energy system. The sonnenPro EMS is compatible with the sonnenPro Compact and sonnenPro FlexStack.
Yes, the sonnenPro Cascade can optionally be supplemented with the sonnenProtect 8000, making it backup power capable. Depending on the design, it can help continue to supply selected consumers or critical areas with energy even in the event of a power outage.
The specific backup power solution always depends on the system configuration, on-site requirements, and the consumers to be supplied. Therefore, our specialist partners always individually assess and plan the backup power capability for each project.
Since its founding, sonnen has exclusively relied on lithium iron phosphate technology. While we base our technology selection on current knowledge, we ultimately rely on our own expertise. Therefore, we have thoroughly tested all batteries we use over long periods to guarantee maximum safety and longevity for our customers. In our specially built battery laboratory, we have 10 years of experience testing batteries for home storage systems and have built up extensive expertise in this area.
We constantly test a large number of different battery technologies from many different manufacturers. So far, however, only lithium iron phosphate technology has passed our tests to the extent that its use in home storage systems is justified from our perspective. Since sonnen is fundamentally technology-agnostic, sonnen can use other battery technologies at any time if they meet the requirements for safety, longevity, and market-appropriate costs. However, this has not yet been the case.
sonnenBatterie owners receive a warranty on all components for 10 years or 10,000 charging cycles. The sonnenHome manufacturer's warranty applies to this. The guaranteed storage capacity of the modules is still at least 80 percent after 10 years or 10,000 charging cycles.
This means sonnen clearly exceeds, for example, the requirements of the state-owned KfW bank, which only provides a replacement value guarantee.
