## Summary description

The Keno DC+AC connection box is designed for photovoltaic systems, supporting 2 PV strings and 2 MPPT inputs. It features a 1000V Type 2 DC surge protector and a 25A 3-phase Type 2 AC surge protector. This unit ensures safe and reliable integration of solar panels with the electrical grid, providing essential overvoltage protection for both DC and AC sides in residential or commercial solar installations.

## Long description

The Keno DC+AC connection box is a professional-grade solution engineered to streamline the integration of photovoltaic systems. Designed to support 2 PV strings and 2 MPPT inputs, this unit serves as a critical junction for managing solar energy flow while ensuring the safety of your electrical infrastructure. By combining DC and AC protection in a single, robust enclosure, it simplifies installation and enhances the reliability of residential and commercial solar power setups.
Advantages
This connection box offers comprehensive protection by integrating high-quality surge suppression for both the DC and AC sides of the system. The inclusion of a 1000V Type 2 DC surge protector and a 25A 3-phase Type 2 AC surge protector effectively mitigates the risks associated with voltage spikes and atmospheric discharges. Its compact design facilitates efficient space utilization, while the pre-configured architecture reduces the time and complexity required for professional installation.
Suitable for
Residential solar power installations
Commercial photovoltaic systems
Systems utilizing 2 PV strings and 2 MPPT controllers
Grid-tied solar energy setups requiring overvoltage protection
When it may not be suitable
This unit is not designed for systems exceeding 1000V DC or those requiring protection for more than 2 PV strings. It is also not suitable for single-phase AC grid connections, as it is specifically configured for 3-phase electrical systems.
Key specifications
Input capacity: 2 PV strings
MPPT support: 2 MPPT inputs
DC surge protection: 1000V Type 2
AC surge protection: 25A 3-phase Type 2
Application: Photovoltaic system integration
How to use
The connection box should be mounted in a location protected from direct environmental exposure, ideally near the inverter or the main distribution board. Connect the DC inputs from the solar panels to the designated terminals, ensuring correct polarity. The AC output should be wired to the 3-phase grid connection point according to local electrical safety standards. All connections must be tightened to the specified torque to prevent overheating and ensure long-term operational stability.
What to consider before purchase
Verify that your inverter supports 2 MPPT inputs
Ensure your solar array voltage does not exceed 1000V DC
Confirm that your electrical grid is a 3-phase system
Check local regulations regarding surge protection requirements for solar installations
Usage recommendations
Regularly inspect the surge protection indicators to ensure the devices remain functional. If a surge protector has triggered, it must be replaced immediately to maintain system safety. Annual maintenance by a qualified electrician is recommended to verify the integrity of all electrical connections.
