This protection device is installed between the solar inverter and photovoltaic panels. It provides the safest way to isolate solar PV strings with high current and voltage up to 600V. 

APPLICATION EXAMPLES

Assume that you have 5 strings of 3 panels in each string. That means 9A per string and total current from 5 strings 45A. This amount of power requires a 63A isolator. 

The BB1 Series of Volta-Switch, is a PV DC Isolator mainly used in PV solar systems with combiner boxes and controllers. It offers effective disconnections and Anti-reflux protection. For additional protection, we added in the design arc-extinguishing technology.

This product complies with IES60947-3/GB14048-3
