Main benefits of the KOSTAL BackUp Switch:

• Reliable backup power mode during grid outages
• Compact design, requiring only 8 modular spaces in the control cabinet
• Seamless integration with PLENTICORE G3 inverters
• Manual changeover switch for easy transition to backup mode
• Integrated cable break detection for enhanced safety
• Supports up to 63 amps of current for domestic connections

Ensured backup power during grid failures

If the public grid fails, the KOSTAL BackUp Switch offers a cost-effective solution to disconnect the house grid and seamlessly transition to backup mode using the PLENTICORE S, M and L G3 inverters and battery storage. Once the house is disconnected from the public grid, the system restores power to the home from self-generated solar energy and stored battery power, allowing critical circuits to stay powered even during grid outages.

Simple installation and space-saving design

Designed for quick installation, the BackUp Switch requires only eight modular spaces in the control cabinet and is mounted on a top-hat rail. It uses a single AC connection for both grid and backup modes, streamlining installation and reducing costs. Existing safety features, such as circuit breakers and residual current devices, remain in place for continued protection.

Seamless integration with KOSTAL PLENTICORE

The KOSTAL BackUp Switch works in conjunction with the PLENTICORE G3 inverter, which automatically detects when the grid power fails. The manual changeover switch allows you to quickly switch to backup mode, and the inverter resumes operation, supplying energy to selected circuits or even the entire home.

Enhanced safety and flexibility

The BackUp Switch includes integrated cable break detection for added safety and is compatible with all third-generation PLENTICORE inverters. Its flexible design supports domestic electrical systems up to 63 amps, ensuring that your home remains powered when it matters most.
