# Step-by-Step: Configuring backup power 

[Demand for commercial-grade backup solutions (in Germany) is rising rapidly](/information-resources/blog/autarky-in-germany-2026-why-backup-solutions-are-dominating-the-market). Here is how to ensure your German installations perform flawlessly according to local expectations:

1. **Optimal module layout for German weather:** Leverage the low-light performance of [Denim Solar](/brands/denim/) modules to ensure sufficient battery charging during the grey winter months typical in Germany.
2. **Backup Prioritization for SMEs:** Configure the [Growatt ACE](/brands/growatt/growatt-commercial-battery) to maintain a mandatory safety reserve (State of Charge). This is critical for German commercial clients who require a guaranteed energy buffer for emergency operations.
3. **Switch-Over Accuracy:** Test the automatic switch-over time. In critical German manufacturing or office environments, loads must transition within milliseconds to avoid data loss or machine downtime.
4. **German Compliance & Briefing:** Ensure the installation meets German safety standards (VDE) and brief the client on which machinery or building sections are prioritized to maximize the battery’s runtime during a localized outage.
