## Long description

The Keno SH-5 DC is a professional-grade hermetic connection box engineered specifically for photovoltaic systems. Designed to manage a single PV string with one MPPT input, this unit integrates a high-performance Type 1+2 DC surge arrester rated for 1000V. It serves as a critical safety component, protecting sensitive solar equipment from voltage spikes and atmospheric discharges, while its durable, weather-resistant housing ensures long-term reliability in various outdoor conditions.
Advantages
The primary benefit of the Keno SH-5 DC is its comprehensive protection against overvoltage, which significantly extends the lifespan of solar inverters and other system components. The hermetic design provides excellent resistance to moisture, dust, and temperature fluctuations, making it ideal for demanding outdoor installations. By consolidating the connection and protection functions into a single, compact, and pre-wired unit, it simplifies the installation process and reduces the time required for system commissioning.
Suitable for
Residential solar power installations
Small-scale commercial photovoltaic systems
Systems requiring protection for one PV string and one MPPT input
Outdoor environments exposed to weather elements
When it may not be suitable
This connection box is not suitable for systems requiring multiple PV string inputs or those exceeding the 1000V DC rating. It is also not intended for use in indoor environments where a non-hermetic, standard electrical enclosure would suffice, or for systems that already have integrated surge protection at the string level.
Key specifications
Rated voltage: 1000V DC
Surge protection class: Type 1+2
Number of PV strings: 1
Number of MPPT inputs: 1
Enclosure type: Hermetic, weather-resistant
How to use
The Keno SH-5 DC should be mounted in a vertical position on a stable surface near the solar inverter or at the string entry point. Ensure that the cable glands are tightened correctly to maintain the hermetic seal. Connect the positive and negative conductors from the PV string to the designated terminals inside the box, and connect the output cables to the inverter input. The grounding terminal must be connected to the building's main earthing system using a conductor of appropriate cross-section to ensure effective surge dissipation.
What to consider before purchase
Verify that your system voltage does not exceed 1000V DC.
Ensure the box matches your requirement for a single string and single MPPT configuration.
Check the local electrical regulations regarding surge protection requirements for solar installations.
Confirm the mounting location allows for easy access for future inspections.
Usage recommendations
Regularly inspect the surge arrester status indicator to ensure the protection module is functional. If the indicator changes color, the protection cartridge must be replaced immediately to maintain system safety.
