Keno SH-98 DCAC Connection Box with DC and AC Surge Protection, 1000V, Type 2, 2x PV String, 2x MPPT

The Keno SH-98 DCAC connection box is a professional-grade electrical component engineered to provide comprehensive surge protection for photovoltaic systems. Designed for high-performance solar installations, this unit integrates both DC and AC Type 2 surge protection within a single, robust housing. It is specifically optimized for systems operating at up to 1000V, offering support for two independent PV strings and two MPPT inputs to ensure efficient energy management and enhanced safety for your solar array.

Advantages

This connection box offers a streamlined approach to solar system safety by combining essential protection mechanisms into one compact enclosure. By utilizing Type 2 surge protection, it effectively mitigates the risk of damage caused by transient overvoltages, thereby extending the lifespan of your inverter and other sensitive electrical components. The design simplifies the installation process by reducing the need for multiple separate protection devices, ensuring a cleaner and more organized wiring setup for both residential and commercial solar projects.

Suitable for

• Residential solar power installations
• Commercial photovoltaic systems
• Solar arrays utilizing dual MPPT inverters
• Systems requiring protection for two independent PV strings

This unit may not be suitable for industrial-scale solar farms that require higher voltage ratings exceeding 1000V or systems that necessitate Type 1 surge protection for direct lightning strike mitigation. It is also not intended for off-grid systems that do not utilize standard AC grid-tie configurations.

Key specifications

• Maximum operating voltage: 1000V DC
• Surge protection class: Type 2
• Input capacity: 2 PV strings
• MPPT support: 2 MPPT inputs
• Integrated protection: DC and AC circuits

Installation should be performed by a qualified electrician in accordance with local electrical codes and safety regulations. The box should be mounted in a location that allows for easy access while remaining protected from direct environmental extremes. Ensure all cable connections are tightened to the specified torque settings to prevent overheating and ensure optimal electrical conductivity throughout the system.

What to consider before purchase

• Verify that your inverter supports the 2 MPPT configuration
• Ensure your system voltage does not exceed the 1000V limit
• Check compatibility with your existing solar panel string layout
• Confirm that Type 2 protection meets your local safety requirements

Regular inspections of the surge protection status indicators are recommended to ensure the device remains fully functional. If the indicator shows a fault, the protection module should be replaced immediately to maintain system safety.
