## Summary description

The Keno SH-1 DC is a hermetic junction box designed for photovoltaic systems. It features a built-in Type 2 DC surge arrester rated for 1000V, specifically configured for 1 PV string and 1 MPPT input. This protective enclosure ensures safe and reliable connection of solar panels, providing essential overvoltage protection for DC installations in residential or commercial solar energy systems.

## Long description

The Keno SH-1 DC is a professional-grade hermetic junction box engineered specifically for photovoltaic installations. This robust enclosure provides a secure and weather-resistant housing for critical DC electrical components, ensuring the longevity and safety of your solar energy system. Equipped with a high-performance Type 2 DC surge arrester rated for 1000V, it is optimized for systems utilizing a single PV string and one MPPT input, effectively shielding your inverter and panels from dangerous voltage spikes caused by atmospheric discharges or grid fluctuations.
Advantages
The primary benefit of the Keno SH-1 DC is its integrated protection mechanism, which significantly reduces the risk of damage to sensitive solar equipment during electrical surges. Its hermetic design offers superior protection against dust, moisture, and environmental factors, making it suitable for both indoor and outdoor mounting. By centralizing the connection point and incorporating surge protection in one compact unit, it simplifies the installation process, reduces wiring complexity, and enhances the overall reliability of the solar power plant.
Suitable for
Residential solar power systems with a single string configuration
Small-scale commercial photovoltaic installations
Protection of MPPT inputs in string inverters
Outdoor and indoor solar energy setups requiring weather-resistant enclosures
When it may not be suitable
This junction box is not suitable for systems requiring multiple PV strings or multiple MPPT inputs, as it is specifically configured for a single string setup. It should not be used in high-voltage systems exceeding 1000V DC, as this would exceed the rated capacity of the internal surge protection components.
Key specifications
Rated voltage: 1000V DC
Protection type: Type 2 surge arrester
Configuration: 1 PV string, 1 MPPT input
Enclosure rating: Hermetic/Weather-resistant
How to use
The unit should be mounted on a stable, vertical surface near the inverter or at the end of the PV string run. Ensure that the cables are routed through the provided cable glands to maintain the hermetic seal of the enclosure. Connect the positive and negative DC cables from the PV array to the designated input terminals and connect the output terminals to the inverter. The surge arrester must be properly grounded to a reliable earth connection to ensure effective dissipation of overvoltage energy.
What to consider before purchase
Verify that your solar system configuration matches the 1 PV string and 1 MPPT input requirement.
Ensure the maximum system voltage does not exceed 1000V DC.
Check the available mounting space to ensure the enclosure fits comfortably in your desired location.
Confirm that you have the necessary grounding infrastructure available at the installation site.
Usage recommendations
Regularly inspect the surge arrester status indicator to ensure the device is still operational. If the indicator shows a fault, the surge arrester cartridge should be replaced immediately to maintain system protection.
