Product information

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.
