After the convergence in the intelligent photovoltaic junction box, the output is through the DC circuit breaker, and it is used in conjunction with the photovoltaic inverter to form a complete photovoltaic power generation system and achieve grid connection with the city power. In order to improve the reliability and practicality of the system, photovoltaic dedicated DC lightning protection modules, DC fuses and circuit breakers can be configured in the intelligent photovoltaic junction box, and working status indicator lights, lightning counters, etc. can be set to facilitate users to timely and accurately grasp the working conditions of photovoltaic cells and ensure that the solar photovoltaic power generation system can achieve maximum effectiveness.
