DC disconnector for photovoltaic systems for 4 MPPT FoxESS 1500DC FOX-S-BOX_PLUS

DC Disconnector for Photovoltaic Systems – Safety and Efficiency

This DC disconnector, dedicated to photovoltaic systems with FoxESS inverters equipped with 4 MPPTs, is a key element ensuring the safety and reliability of the installation. The device allows for quick and effective disconnection of photovoltaic panels from the inverter in emergency, service, or maintenance situations. Its robust construction and high degree of protection make it an ideal solution for both professional installers and end users.

Design and Application

The disconnector is designed to operate at voltages up to 1500V DC and a current of 25A per string, making it compatible with most modern photovoltaic installations. Equipped with a motor drive, it ensures smooth and reliable switching of circuits. The housing with an IP66 protection rating guarantees resistance to weather conditions, and the built-in venting valve minimizes the risk of condensation inside the device. A particularly important function is the automatic shutdown at 70°C, which further increases the safety of the system. The device is supplied with connectors, which simplifies and speeds up installation.

Advantages and Benefits

• Safety First: Automatic shutdown in case of fire or network failure protects both firefighting teams and the photovoltaic system itself. In the event of a network failure detected after the AC power is switched off by firefighters, the disconnector automatically cuts off the DC circuit.
• Quick Installation: AC and DC leads and a complete set of supplied connectors significantly reduce installation time and facilitate connection to the existing installation.
• High Reliability: Robust housing made of PC+ABS and CE certificates guarantee long-lasting and trouble-free operation of the device.
• Overheat Protection: Automatic shutdown at 70°C protects against damage to installation components due to excessive temperature.
• Compliance with Standards: The operation of the disconnector complies with EN 60947-1&3, confirming its safety and quality.
• Versatility: Designed to handle four strings, allowing for use in various photovoltaic installation configurations.
• Weather Resistance: IP66 protection rating ensures tightness against water and dust, allowing for outdoor installation.
