DC disconnector for photovoltaic systems for 2 MPPT FoxESS 1500DC FOX-S-BOX

Safety and Reliability in Photovoltaic Installations

The DC Disconnector FOX-S-BOX is a key element ensuring safety in photovoltaic systems with two independent MPPTs, dedicated to cooperation with FoxESS inverters. In addition to the standard DC circuit disconnection function, this device offers additional fire protection, meeting the requirements of the latest legal regulations. Its design and functionality are intended for both professional installers and end-users, providing easy installation and trouble-free operation.

Design and Functionality

FOX-S-BOX is a motorized disconnector designed to safely cut off the DC voltage from photovoltaic panels in the event of a failure or fire. Thanks to automatic shutdown at 70°C, it minimizes the risk of fire spreading. The device is equipped with an IP66 protection class housing, which guarantees resistance to weather conditions and the possibility of outdoor installation. The set includes complete MC4 connectors, making the installation process easier and faster. Additionally, the built-in condensate drain valve prevents moisture from accumulating inside the housing, extending the device's lifespan.

Application and Benefits

This disconnector is used in domestic and commercial photovoltaic installations where high safety and reliability are required. Automatic shutdown in the event of AC voltage failure on the AC side (e.g., after fire department intervention) provides an additional layer of protection. Thanks to supporting two strings (chains) of photovoltaic panels, it allows for optimization of system operation and increased energy generation efficiency. Simple operation and no need to reset after shutdown make the device extremely convenient to use. Compliance with EN 60947-1 and 3 standards and possession of CE certificates confirm the high quality and compliance with European safety standards.
