Adopting PV-specific DC circuit breakers of well-known brands at home and abroad, the working voltage is up to 1000V, the performance is stable and
reliable. The input end of the cabinet can be equipped with anti-reverse diodes to prevent reverse connection or short circuit, and protect the combiner
box and inverter from being affected;
Each input or output is configured with a configurable DC current sensor for monitoring and measuring the current at the input and output terminals. The
voltage output transmitter is configured at the bus output terminal to monitor the photovoltaic output voltage and monitor the working state of the input
and output circuit breakers;
It can detect the insulation of the input and output circuits to ensure the safe and stable operation of the system;
All monitoring and measurement data can be transmitted to the background monitoring through the RS485 communication interface, and the actual
situation of photovoltaic power generation can be mastered without going to the scene;
Built-in temperature and humidity sensor and controller, adjust the operating conditions in the cabinet at any time to ensure stable operation of the
system in a suitable working environment;
The operating element and the heating element are arranged separately, and the protective partition is added to effectively prevent the touch from being
touched, and the circuit breaker is protected from the heating element;
The output is equipped with a special lightning protection module for photovoltaics, which effectively protects the circuit breaker and the inverter from
overvoltage.
